OK, I cannot find any VB samples, (different issue if I was doing things in C#). Any way, I am using WebClient class and am successfully reading the XML file of business videos in my xaml.vb file asynchronously. But I am having a problem populating the datagrid properly:
My XML has these nodes:
<videos>
<profession name="lawyer">
<video id="1" title="Lawyer Title 1" />
<video id="2" title="Lawyer Title 2" />
</profession>
<profession name="doctor">
<video id="1" title="Doctor Title 1" />
<video id="2" title="Doctor Title 2" />
</profession>
</videos>
Here's my query
Dim BizVideos = _
From videos In xmlVideos.DescendantsAndSelf("profession") _
Where videos.Attribute("name") = "doctor" _
Select videos
dgridVideoList.ItemsSource = BizVideos
Here's the problem I am experiencing:
1. I am only getting one row in the datadrid with everything included in that one row, as opposed to what I want, i.e. one row for Video ID 1, and one for Video ID 2.
2. I am getting more fields in the datagrid than I want, i.e. "Has Elements", "Has Attributes", "Parent Node", etc.
Can anyone offer me (a.) the correct syntax for the query where I can break out the video child nodes under profession doctor and diplay them one video per row (b.) avoid showing superflulous fields like "Has Attributes", "Parent Node", etc., as well as (c.) what I am doing wrong in the binding of my datagrid?
Thank you all for your help.

I've been evaluating around 5 third-party WPF datagrids for my project.. Each Datagrid has some issues.. (Ref[^])
The following are my requirement for buying WPF datagrid..
* Controls inside the Datagrid Column: I wanna display one or more WPF controls (e.g. Checkedbox or Combobox, Textbox or etc) inside the column of Datagrid. Plus, I should be able to set/get the value to/from those controls at runtime.
* Excel-Like Filtering: Should we call it as the row filtering? In Microsoft Excel, we are able to filter by the rows.For example: There are ten student records showing in Datagrid and those students are from Math Major and Physic Major. So, I should be able to filter those students by Major. Yes. it’s like grouping but if I say “grouping”, you might get confused with grouping features of Datagrid.
* Sorting, Grouping: Of course!
* Hierarchical display: Same as Grouping featuer? (Importantly, It would be better if we can specify the appearance of hierarchical in XAML)
* SelectedItem Binding (two ways): I believe that this feature should be included in every datagrid but surprisely, I found a few datagrids that don’t provide this feature. Weird.
* Less work from Code-behind file: What does it mean? It means, I should be able to do the most of works in XAML. In my current project, we are using MVVM (Model-View-ViewModel) pattern with CompositeWPF (Codename: Prism) framework so we do the most of jobs in either XAML or ViewModel (which is not a code-behind file) and we try not to write as much as possible in code-behind file.
It would be great if anyone can recommend some cool WPF datagrid control.. Thanks in advance...

I've only used two of note, both of which I'm sure you'll have already tested.
Xceed WPF Grid & Infragistics XamDataGrid.
I'm working on a project for my own company and I'm also working on a large LOB WPF app for my employer, both are using the XamDataGrid. We too are using MVVM (Dan's flavour) in the LOB app. So far we are really pleased with the XamDataGrid. Before opting for the XamDataGrid I test run a few myself and wasn't overly impressed. The Component One stuff just looks terrible in my opinion. The Xceed looks good but due to us wanting to buy a complete suite we ended up opting for the Infragistics stuff (we wanted a good chart as well). In my opinion the Infragistics stuff is still the WPF suite of controls to measure things by.
That said I had an interested reply from one of the sales guys as Nevron. He basically said that for their WPF offering (not available yet) they were going to be implementing their own framework which will be merely hosted by WPF citing performance as their reasoning. I'll be looking out for that as I'm intrigued to find out exactly what he was on about. I've been using the XamDataGrid with datasets of 100,000+ records and i've not had any problems ...
There are a few other small component houses that are making things but they really don't compare to Infragistics yet. Not to mention that the support and developer interaction that I've had with the Infragistics folks has been exemplary. That's worth the price of admission. Don't forget that you can get a full blown copy of the XamDataGrid for FREE!!!! Look for their Express suite ... you get the grid, checkbox and an editor for zilcho ... nada ... nothing ... wooo!
Just out of interest, what have you found that you have liked??

I have tested 5 third-party controls and updated my post yesterday..
Based on my experience, Infragistics/C1 are so unstable for now even though they are big companies.
I like Xceed Datagrid and I think their doc and samples are really great.... I got one reply from Xceed in their forum.. http://xceed.com/CS/forums/thread/13984.aspx[^]
Hopefully, they can solve the problem that Im having now.

Infragistics?? Unstable???
Are you sure we're talking about the same things??? I have an app out at Beta testing stage using that grid and no-one is reporting problems with the grid ...
What exactly do you mean by unstable?

Please take a look at my post[^]?
I have four problems. It would be great if you can help me to solve those problems..

okay. If you don't want to go to my blog, I will post those issues here. Hope, you may suggest something...
* No SelectedItem: There is no dependency property called SelectedItem or equalivalient in xamlDatagrid. But they do have SelectedItems (with s). I wonder what wrong with SelectedItem. I don’t allow the user to select more than one row at a time so why do I need to loop through the SelectionItem list to get that selected item. Weird.
* Can’t get the reference of controls inside the Datagird: Maybe, I don’t know the correct way of doing this. And also, there is no documentation or sample for that. I tried to use VisualTreeHelper class to walk throught each and every element of Datagird but I just can’t find the controls which are inside DataTemplate. (It’s so easy to do with Xceed Datagrid.). Okay. Never mind.
* Showing the incorrect record if the datasource has some filters: I was using ListCollectionView as a datasource to bind the datagrid. There are some records that need to be excluded so I used the filter predicate for excluding those unnessary records. Then, I binded that ListCollectionView with Datagird. It works for the first time. So, I added new record to ListCollectionView and make it refresh. Opps! it shows the exclued record. crazy! then, I put WPF listview to find out whether this is a ListCollectionView problem or datagrid problem. And I found that it’s working fine with ListView. This issue is really crazy..
* Showing wrong checkedstate when scrolling: Here is another crazy issue. I created three columns for Datagrid in XAML. One of three columns has the checkbox inside. I showed around 30 records on the datagrid but only 10 rows are viewable within datagrid since I specify the height of datagrid explicitly. Then, I run the problem and checked a couple of checkbox. After that, I scrolled up and down a bit then the checkbox that I haven’t checked are automatially checked after scrolling.

Just reading the bit you did on XamDataGrid (since this is what I have most experience with) ...
1. Their "SelectedItem" is called "ActiveRecord" ...
2. I have loads of embedded controls in our grids with no problems. All easily controlable, I have some dynamically animated based on the grids contents as well.
3. In the app I'm doing for my company I used filters extensively to sort the results in the grid, not sure why you'd see problems here.
4. Not sure what is going wrong here, they did have an issue with the checkboxes that was fixed in a hotfix some months ago now.
Anyway, seems like you decicded on Xceed now. Although I'm not sure you have given them all a good thorough testing however.

Is this bindable? Let's say I bind this "ActiveRecord" with AA Get/Set property. If I select one row after another on datagrid, can i get the selected record from AA property?
Jammer wrote: 2. I have loads of embedded controls in our grids with no problems. All easily controlable, I have some dynamically animated based on the grids contents as well.
How can I get the reference of those embedded controls? I wanna use like DG.Row[1].Cell[1].FindControl("myextendedtextbox")
Jammer wrote: 3. In the app I'm doing for my company I used filters extensively to sort the results in the grid, not sure why you'd see problems here.
Are you using ListCollectionView.Filter? Did you bind it to Datagrid? Have you tried to add new item to that ListCollectionView? I'm not sure why I got that error, man.
>>seems like you decicded on Xceed now.
Not yet. I'm doing with Telerik Datagrid before I got the solution from Xceed. If Xcced can give me some solutions, I may use that grid. Otherwise, I hav to go with Telerik....

Good people,
I have assigned several items (including the background of my MainWindow) to a particular brush. My strategy is that instead of changing several different components (e.g. border background colors, border colors, control background colors, etc...), I can just change the color of the brush they all use via procedural code. The colors will change based on user preferences.
Unfortunately, when I try to do that, it doesn't work. The code is as follows:
public void SetClassicThemeBrushes()
{
// WindowMainBackground
Brush WindowMainBackgroundBrush = (Brush)TryFindResource("BrushWindowMainBackground");
WindowMainBackgroundBrush = (Brush)TryFindResource("MyCoolBreezeGradientBrush");
}
In the first line of code, attempt to get a reference to the existing brush that the components are assigned to. In the second line of code, I try to assign another color brush to the WindowMainBackground brush hoping it changes its color. Now I am wondering if all I have done is change a reference and not the color. Any idea on how I change the colors?
Any thoughts?
Thanks,
BP

You could either set a new value in the resource dictionary:
Resources["BrushWindowMainBackground"] = (Brush)TryFindResource("MyCoolBreezeGradientBrush");
Or change the brush itself, I don't know if this would work in all situations but it seemed to in this one.
SolidColorBrush b = (SolidColorBrush)TryFindResource("BrushWindowMainBackground");
b.Color = Colors.Green;
Also make sure your using DynamicResource in the xaml and not StaticResource.

Thanks, I will try that and see what happens.
Also, what do you think about using styles?
|
|
|
|

Actually, it worked. By the way, what do the Brackets "[]" mean? What do they do that parentheses would not?
Thanks,
BP

This is something you need to plan carefully imho.
At work I've spent about a month putting together/organising thousands of lines of styles into a style dll. We are planning on having a few 'skins' that users can choose from. Personally I prefer the idea of offering skins over allowing a user to change individual colours since that can wind up with an horrific mish mash of contrasting rubbish in the UI.
Have a look at this article on CP its where I started along this path and its a seriously cool CP article in general that covers this topic really well.

Hey guys.
I'm totally new to WPF and I'm trying to write a control with it. The control is a calender and will be used as a roster where the user will select a shift to use for a specific day and then when one cycle has been set up the user must be able to copy that cycle for the rest of the year for example.
Here is the XAML code i have so far... Sorry if its a bit long

As you can see ive got "Canvas" objects within the grid, but im not sure if thats the right control for what i need it to do.
at this point i need to be able to some painting on it from the code behind, depending on which month & year is selected the day numbers need to be drawn in the right blocks, but i cant seem to figure out how to do that... my brain is still thinking in GDI 
any help would be appreciated

WRAP PANEL ALERT!!!!
Have a look into the wrap panel. Also you could:
<Style x:Name="CalCellBorder" TargetType="{x:Type Border}">
<Setter Property="BorderBrush" Value="Black"/>
<Setter Property="BorderThickness" Value="0.5" />
<Style>
Then, if the style is placed inside:
<UserControl.Resources>
</UserControl.Resources>
Such As:
<UserControl.Resources>
<Style x:Name="CalCellBorder" TargetType="{x:Type Border}">
<Setter Property="BorderBrush" Value="Black"/>
<Setter Property="BorderThickness" Value="0.5" />
<Style>
</UserControl.Resources>
You can then do:
<Border Grid.Column="5" Grid.Row="5" Style="{StaticResource CalCellBorder}"/>

The first thing that jumped out at me is that you are not nesting the controls. The way it stands now, the Canvas and Label elements will end up on top of instead of inside the Borders in the same grid cell. My guess is that you are using the Rectangles as a background color for certain cells; if so, you can use the Background property of the Border instead.
Personally, I would use the lighter-weight TextBlock instead of Label (which unlike its Forms cousin can show a wide range of content) if all you will show is text.
As for the using a Canvas, if all you want to do is put the date in the cell, I would again use a TextBlock inside the Border and change the Text property to match the day you need.

Hi All,
Is this possible? You have a button in the UI with its content property set as:
XAML:
<Button x:Name="btn" Content="Original Value" />
Then in your C# code you change that Content property to be something else like:
CS:
btn.Content = "New Value";
Can you subsequently access the original value set in XAML without the need for doing something like this in more C#:
btn.Content = "Original Value";
I can't even seem to find the array of _effectiveValues for a button in Visual Studio ...
|
|
|
|
|
They both count as the local value so I think your better off keeping track of the original value yourself. If you set the xaml value using a style you could do it but that seemed to be an ugly hack.
|
|
|
|
|
Using an attached property to store the original value works quite well. You probably wouldn't want to declare the attached property in a window as I have done.
<Button x:Name="b" Click="b_Click" local:Window1.OriginalContent="OriginalValue" />
void b_Click(object sender, RoutedEventArgs e)
{
var newValue = "New Value";
var original = GetOriginalContent(b);
b.Content = b.Content.Equals(newValue) ? original : newValue;
}
#region OriginalContent Attached Property
public static readonly DependencyProperty OriginalContentProperty = DependencyProperty.RegisterAttached("OriginalContent", typeof (object), typeof (Window1), new UIPropertyMetadata(Changed));
private static void Changed(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
((ContentControl) d).Content = e.NewValue;
}
public static object GetOriginalContent(DependencyObject d)
{
return d.GetValue(OriginalContentProperty);
}
public static void SetOriginalContent(DependencyObject d, object value)
{
d.SetValue(OriginalContentProperty, value);
}
#endregion
|
|
|
|
|
Interesting idea ...
When I get to work in a couple of hours I'll dig out the code that I used to get at the _effectiveValues and see if anything can be done with that. I'll post it here as well.
Urgh, I feel sick just thinking about it!!
Thanks for this Dave.
|
|
|
|
|
Indeed, I was looking through the results of the LocalValueEnumerator and trying ReadLocalValue etc ...
I've had lots of fun in the past coding round the _effectiveValues array. Its really not pretty code at all. According to one thing I read this whole area of WPF is 'unfinished'. I just hope that in the next version some of this stuff is 'fixed' or 'completed'.
|
|
|
|
|
I've just tried this:
object _buttonContent = btnLoadData.ReadLocalValue(ContentProperty);
if (_buttonContent != DependencyProperty.UnsetValue && _buttonContent != null)
{
Type tx = _buttonContent.GetType();
PropertyInfo pinfo = tx.GetProperty("Content");
if (pinfo != null)
{
object objPropertyValue = pinfo.GetValue(_buttonContent, null);
string BtnContent = objPropertyValue as string;
}
}
No luck, as you say they both count as local values. There doesn't seem to be any way of 're-reading' the XAML Content="Original Value" ...
That just seems absolutely NUTS to me ... it must be doable ... surely ...
