Why must the TextBox be built into the grid control? You could simply host your DataGrid inside a Grid with two rows, and set the first row to contain the TextBox.
|
|
|
|
|
The incremental search (which is one example) is a must for every datagrid in my applications and I use a lot of datagids some are created by code in runtime so you don't want to create the textbox and write all the code to do the search every time.
The most important thing in deriving the datagrid which is a very important control in my application is the ability to improve the datagrid all the time and all your applications get the benefit from it withot chaging your source code.

So just wrap it in a UserControl and use that. Seriously, you'll save a lot of heartache and effort over retemplating the DataGrid.
|
|
|
|
|
When wraping to User Control you are losing all the DataGrid design time properities and events. If there was an easy way to expose all the DataGrid properties then User Control will be graet.
|
|
|
|
|
Then you're on your own mate. We've tried to offer practical ways around this, but if you're absolutely set on retemplating then fly at it. You can download the DataGrid template from Microsoft.

I'm not sold on Silverlight/WPF's approach to controls, either, to be honest. Inheriting from WinForms controls is more comparable to Delphi and I find it nicer, in general.

hello guys... I am having difficult time and am unable to find the panel control (in Silverlight) inwhich we can group some of the controls (like labels, textboxes and buttons) and then name that group in top left corner of that panel. How to get/add/find that control and add on the silverlight app? thnx

u can use stackpanel for this... and for groupbox a free dll is available in codeplex u can google it n use it...
|
|
|
|
|
Have u tried System.Windows.Controls.GroupBox?
Just right-click anywhere in your tool box and then "select items" (or is it "select elements" I'm using the german version of VS2010) and type groupbox in the filter text box. Then select "GroupBox", click ok and you'll find it in the tool box. (The icon shows a small box labeled "XY")

Hello All,
I have strange problem. I have used WCF services in my Silverlight applications. Sometimes, WCF service called twice.
I have set following properties for the BasicHttpBinding.
-- binding.MaxBufferSize = Int32.MaxValue;
-- binding.MaxReceivedMessageSize = Int32.MaxValue;
For overcoming such type of situations, I have unregistered the WCF method call and its working fine. Is it proper solutions for that?
It would be gr8 if anyone can explain me, why such type of issue happens.

[EDIT] My bad, it was date against int, solved!
I have a scatter view with point and the axis are date against date (I know, weird, but work out quite well, i.e. very meaningful user experience).
At any rate I have trouble with the Y axis setup.
Here is my current XAML:
<chart:Chart TitleStyle="{StaticResource NoTitle}">
<chart:Chart.Axes>
<chart:DateTimeAxis
Orientation="X"
IntervalType="Months"
AxisLabelStyle="{StaticResource maxis}"
Minimum="2000/07/01"
Maximum="2001/06/30"
/>
<chart:DateTimeAxis
Orientation="Y"
IntervalType="Years"
>
</chart:DateTimeAxis>
</chart:Chart.Axes>
<chart:ScatterSeries
Title="{Binding ScatterTitle, ElementName=root}"
ItemsSource="{Binding GraphData, ElementName=root}"
IndependentValuePath="Date"
DependentValuePath="Value"
DataPointStyle="{StaticResource spoint}"
/>
</chart:Chart>
This kind of work except... I have 2 Y-Axis! One of the left with just the year, as I'd like.
And one on the right with regularly spaces dates (not falling on year start), I don't want it! Anything as a Y value of "xxxx january 1"
how could I get rid of it?
why visit even there?!

Hello,
Is there a simple mean in WPF to make one control overlay on top of another?
- Do you have to programmatically take a way with Adorner?
- Is this not standard?
My case is I have a UserControl named 'MenuControl', to show above another UserControl named 'ViewControl', inside a Window.
<br />
<Window ...><br />
<Grid><br />
<cc:ViewControl x:Name="viewControl" Margin="3,3,3,3" Width="Auto" Height="Auto" /><br />
<my1:MenuControl x:Name="menuControl1" HorizontalAlignment="Right" VerticalAlignment="Center" xmlns:my1="clr-namespace:Application.Controls" /><br />
</Grid><br />
</Window><br />
I am using: .NET Framework 3.5, VS 2008.

It is standard. Grid children will overlap each other if they are positioned that way. Your issue is that MenuControl is set to H Right / V Center, but ViewControl has something different entirely. They will overlap if the window is small enough and the controls are large enough, but if you truely want them to overlap, they needed to be positioned the same way.

Thanks in advance ,
I had downloaded Microsoft Expression 4 trial version, but unfortunately could not use it , i am new to silver light stuff etc, and had not used Mic. Expression before so basically was exploring but used only two to three times because of other projects burden and it has expired
My Question is, Is there any way to increase trial period even i re installed , but its still showing that i have to enter the key. i hope so its not piracy

Luck in life always exists in the form of an abstract class that cannot be instantiated directly and needs to be inherited by hard work and dedication.

Bypassing the limit on such a trial product would be piracy. If you do this make sure you pay your lawyers more than Microsoft pay theirs.

No there isnt. Not any legal way.

Working on our Silverlight Application. (1 year old, yoohoo!  ) everything runs fine, yoohoo!
And then, I press F5 and... I got a blank page with a big sign:
"To view this content, please install: Microsoft Silverlight"
Err... but it's already there with higher version than the minimum required... It already worked for hundreds of hour!
What's going on?!?
I tried again (you know, F5, Debug!) and this time it worked!
Very strange...
I'd like to get to the bottom of that as some customer had similar problem (except, for them, the nagging install screen didn't go away...)

I'm using the WPF DataGrid that comes with .net 4.0.
The DataGrid's ItemsSource is bound to an ObservableCollection of ViewModels - one ViewModel for each Row. The count of rows is constant at any time. Depending on a Property in a row's viewmodel, the row has to be visible or collapsed. I do not want to manipulate the underlying itemssource because I want to keep the data in the viewmodels. I just want to set the Visibility of the rows.
So I created a style and set the DataGrid's "RowStyle" Property to it:
<Style x:Key="MyRowStyle" TargetType="{x:Type DataGridRow}">
<Style.Triggers>
<DataTrigger Binding="{Binding PropertyFromViewModel}" Value="False">
<Setter Property="Visibility" Value="Collapsed" />
</DataTrigger>
</Style.Triggers>
</Style>
This actually works, but the datagrid scrollbar's size is not constant anylonger.
When I scroll through the list, the scrollbar size changes and when I start scrolling from the top of the list, the scrollbar moves, but the list stays where it is. Only when the scrollbar reaches a certain point, the list moves as well.
I have tried filtering the list with a CollectionViewSource, this solves the problem, but makes the triggering of visible/collapsed very slow when changing the property in the view model and refreshing the filtering of the collectionviewsource.

Uhm seems a lot weird to me, surely a ViewModel is designed to service the View, not 1 line of a datagrid in a View, Sorry. I have no idea why the DG is pissed at you, I can understand why it is but can't help with the scroll issue. mutter mutter now thats the weirdest design I have come across yet
Never underestimate the power of human stupidity

With "ViewModel" I mean a class that encapsulates all data for one row. Don't know what might be weird about this. It's just a capsule of data for the columns for each row plus the visibility flag.

Hi all,
I added to an already working (perhaps that was my mistake) a DataGridTemplateColumn containing a Button. The code looks like this:
<DataTemplate xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation' xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml' xmlns:local='clr-namespace:MyAssembly;assembly=MyAssembly>
<Button x:Name='btnShowSubgrid' Tag='{Binding ID}' Click='btnShowSubgrid_Click' Margin='4' Width='20'>
<Button.Content>
<Image x:Name='imgButtonTemplate' Source='Images/rightBlueArrow.png' />
</Button.Content>
</Button>
</DataTemplate>
All columns are runtime generated, and again, if I don't add this column, it all works fine.
This button's tag is bound to a column called "ID". There is another column that binds to "ID" but I don't think that's an issue. Even went as far as to remove all "embellisher" tags and content only leaving it with x:Name only but no luck.
This is how I add the column:
DataGridTemplateColumn buttonColumn = new DataGridTemplateColumn();
using (StreamReader reader = new StreamReader(Assembly.GetExecutingAssembly().GetManifestResourceStream("MyAssembly.CellTemplates.ButtonCellTemplate.xml")))
{
String str = reader.ReadToEnd();
str = str.Replace("(ColumnToBind)", _gridDefinition.SubGrid.Param);
buttonColumn.CellTemplate = (DataTemplate)XamlReader.Load(str);
}
dgGrid.Columns.Add(buttonColumn);
The ArgumentOutOfRangeException is thrown after the MainPage_Loaded event and it says:
Microsoft JScript runtime error: Unhandled Error in Silverlight Application
Code: 4004
Category: ManagedRuntimeError
Message: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: index
at System.Windows.PresentationFrameworkCollection`1.InsertDependencyObject(Int32 index, DependencyObject value)
at System.Windows.Controls.UIElementCollection.InsertInternal(Int32 index, UIElement value)
at System.Windows.PresentationFrameworkCollection`1.Insert(Int32 index, T value)
at System.Windows.Controls.DataGrid.InsertDisplayedColumnHeader(DataGridColumn dataGridColumn)
at System.Windows.Controls.DataGrid.OnApplyTemplate()
at System.Windows.FrameworkElement.OnApplyTemplate(IntPtr nativeTarget)
My DataGrid has AutoGenerateColumns set to "false". Has somebody have the same issue? How have you fixed it?
BTW, I'm using Silverlight 4.
All help is appreciated!
Thanks,
humble.apprentice
