I'd say I usually avoid the ListBox because it makes the UI look "low budget". The work you need to put in should be irrelevant vs the end result. You can customize it, I suppose... but if I was just showing an item with "one column", I'd probably pick a ComboBox.

Somewhere in that HUGE code dump there should be an itemssource={binding observablecollection} and a selecteditem={binding SelectedObject}. The selectedobject then has the information you are looking for, wherever possible use the data container to manipulate your information, NOT your display object.
I do wonder why you used a listbox instead of a gridview, so far I have not ever had to use a listbox.

hi
I my SL 4 project used the Silverlight toolkit control : TimePicker.
I referenced the library the dll : System.Windows.Controls.Input.Toolkit
When i compile as Debug no problem. When colmpile as Release i get the following error(TimePicker) :
-Error 10 The type or namespace name 'TimePicker' does not exist in the namespace 'System.Windows.Controls' (are you missing an assembly reference?) C:\Users\user\Desktop\OLD version project\InfoCopy.SuiteSolution_CR funzionante\InfoCopy.SuiteSolution\obj\Release\Views\Interventi\DettagliStoricoDiarioChild.g.i.cs 221 58
"For as long as men massacre animals, they will kill each other. Indeed, he who sows the seed of murder and pain cannot reap joy and love." Pythagoras

Make sure you have added a reference to the TimePicker in the xaml file where this is being used.
Also, clean your solution once and then try again.
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

hi
yes i added ..
xmlns:inputToolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Input.Toolkit"
"For as long as men massacre animals, they will kill each other. Indeed, he who sows the seed of murder and pain cannot reap joy and love." Pythagoras
|
|
|
|
|
Also tried to clean and rebuild but getting same error

hmm....I just tried and had no problem. What version of the toolkit do you have installed?
Also make sure you've referenced the correct DLL. For example, the path to the assembly I used is C:\Program Files (x86)\Microsoft SDKs\Silverlight\v4.0\Toolkit\Apr10\Bin\System.Windows.Controls.Input.Toolkit.dll

Hi
i downloade from here : http://silverlight.codeplex.com/ The April 2010 Silvelight Toolkit
"For as long as men massacre animals, they will kill each other. Indeed, he who sows the seed of murder and pain cannot reap joy and love." Pythagoras

Should work....works fine here. Make sure the reference exists and is is pointing to the correct assembly in both build configurations.

Hi
In ServiceReference i referenced the System.Window.Controls.Input.Toolkit (i didn't installed the toolkit).
Can you help me with another thing ??
I downloaded the "April2010Toolkit.zip" that contain also the source code .. can i use only the code of TimePicker ???

So you got it working now? How did you reference an assembly that wasn't installed?

I suppose you could, but I wouldn't. The source code is there to allow the community to help with development and debugging as these new things are being developed, but using it in production code is unwise.

No not got it working yet.As i downloaded the "April2010Toolkit.zip", that contains the System.Winodws.Control.Input.Toolkit.dll file, and i referenced to this.

I'm confused. You stated "i didn't installed the toolkit". You need to install it to reference the correct assembly since that's where the control implementation is.
So if you did install it, what's not working?

I am using a Silverlight enabled WCF Service with the following attribute:
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
It has a method say
[OperationContract]
public IEnumerable<Entity> GetAllEntities();
Sometimes I want to call this method multiple times within short span of time.. as WCF calls from Silverlight have to be asynchromous, the second call ends up getting called before the first one returned with the results. This results into the UserState getting corrupted. I find that the UserState of one of the calls gets overwritten by that of another call. I find this problem when the calls return and I extract the UserState from the EventArgs.
This seems to be a concurrency problem. I know we should avoid design which causes such multiple calls in Silverlight, but in some cases you just have to. Is there any workaroung/ solution to this problem?

Well, call the second service once the first one executes. No other choice.
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.
|
|
|
|
|
Just asking....the UserState you refer to is your object right?
Like Abhinav S mentioned, you need to chain the asynchronous calls.

You mean the UserState on the server, right?
Either you need to write the service so that it can cope with being run concurrently, or wrap the content of that method with lock(UserState){ ... }. (You don't want to use [Synchronized] because it should be able to run concurrently for different users, even if making it work concurrently for the same one is too hard.) Obviously, the first way is preferred.
I'm guessing your method is actually not just a 'GetAllXxx' but instead updates some server state, because there should be no problem with doing multiple gets in parallel, and also you would not need to call that multiple times (the result could be cached).
Can you explain a bit more about what the service method is doing and why you need to call it multiple times? I would expect that it would be possible to bundle the requests up into a single service call in some way, reducing network traffic as well as reducing your concurrency issues. But you should still write a robust service regarding concurrency.

I have a datagrid where I have two buttons on each row - one for moving a row up and one for moving a row down.
Each button has a command for allowing the user to move the selected row in either direction. The problem that I am facing is that it not working. I think the problem that I may have is that the other controls (combo boxes) on the rows are bound to data sources through the MVVM model where I am manipulating the rows on the code behind of the XAML thinking this would be the logical place in which to do it.
The code I have for one of the buttons is below:
private void MoveRowDown(object sender, ExecutedRoutedEventArgs e)
{
int currentRowIndex = dg1.ItemContainerGenerator.IndexFromContainer(dg1.ItemContainerGenerator.ContainerFromItem(dg1.SelectedItem));
if (currentRowIndex >= 0)
{
this.GetRow(currentRowIndex + 1).IsSelected = true;
}
}
private DataGridRow GetRow(int index)
{
DataGridRow row = (DataGridRow)dg1.ItemContainerGenerator.ContainerFromIndex(index);
if (row == null)
{
dg1.UpdateLayout();
dg1.ScrollIntoView(selectedAttributes.Items[index]);
row = (DataGridRow)dg1.ItemContainerGenerator.ContainerFromIndex(index);
}
return row;
}

Instead of working with the grid you should work with the data. Add a sort field to the class used to populate the grid and manipulate the order in the VM.

I want to populate a TreeView dynamically during runtime of my program.
The WPF TreeView is for me very confusing and I can't really find any easy and simple guide. I hence this thread will be long because I have lot's of questions. Let's take them one by one.
My XAML is just:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<TreeView Name="tvTree"></TreeView>
</Grid>
</Window>
My C# code is:
namespace WpfApplication1
{
public partial class MainWindow : Window
{
List<Person> persons;
public MainWindow()
{
InitializeComponent();
persons = new List<Person>();
persons.Add(new Person("Person1"));
persons.Add(new Person("Person2"));
persons.Add(new Person("Person3"));
persons.Add(new Person("Person4"));
persons.Add(new Person("Person5"));
tvTree.ItemsSource = persons;
}
}
public class Person
{
string name;
public Person(string name)
{
this.name = name;
}
public string Name
{
get { return name; }
}
}
}
This will actually populate the TreeView with five TreeViewItems:
WpfApplication1.Person
WpfApplication1.Person
WpfApplication1.Person
WpfApplication1.Person
WpfApplication1.Person
This was somewhat expected since the TreeView read the ToString() method from my Person class.
But can I make the TreeView read the person's name from the Name property instead? I don't want to override the ToString() method to do this. I would like to use the Name property and connect that property to the XAML code.

In order to use the TreeView simply in WPF, it's important to understand that a tree represents a hierarchy of information. Another important concept to remember is that you are going to represent the hierarchy by changing the template of the control to display the data in a different fashion. I've deliberately used those words because the thing I want you to remember is that you can change the appearance of data using a DataTemplate, and that as you have a hierarchy of data in the TreeView, it takes a HierarchicalDataTemplate (even though you are only using one level of data, it has to cater for multiple levels).
So, we have a HierarchicalDataTemplate - how do we actually code this in our XAML? Well, we need to apply this to the template for each item (or the ItemTemplate), so you would add something in that represented a single item. In this case, let's use a TextBlock. This would look like:
<TextBlock Text="{Binding Name}" />That's all we need to do to actually bind to the name, but where do we put this? Well, we know that we need to add it into a HierarchicalDataTemplate, so let's add that into our TreeView. It looks like this:
<TreeView Name="tvTree">
<TreeView.ItemTemplate>
<HierarchicalDataTemplate DataType="{x:Type local:Person}">
<Grid>
<TextBlock Text="{Binding Name}" />
</Grid>
</HierarchicalDataTemplate>
</TreeView.ItemTemplate>
</TreeView>Now, you might be wondering why we put a DataType against the HierarchicalDataTemplate. Well, as it's a DataTemplate and there may be multiple different types of data under the tree nodes, the DataType tells WPF which particular type of data to render this TreeView out against. This allows you to build an incredibly complex hierarchy of data in the TreeView, and yet have small self-contained DataTemplate elements reshaping the data easily (don't forget to add a namespace reference so that it knows where to pick Person up from).
I hope this helps.

I know what the TreeView can do in WPF, I just don't know how to do it. So I start very simple and continue on that.
Thanks by the way for the code, it did the trick when I found out how to make a XAML-namespace reference
xmlns:local="clr-namespace:TreeView"
Notice I have change my namespace from WpfApplication1 to TreeView
Now I want to implement the TreeView to add sub TreeViewItems for some of the already existing TreeViewItems. I have changed my C# to:
namespace TreeView
{
public partial class MainWindow : Window
{
List<Person> persons;
public MainWindow()
{
InitializeComponent();
persons = new List<Person>();
Person p1 = new Person("Person1");
p1.Children.Add(new Person("Children1"));
p1.Children.Add(new Person("Children2"));
persons.Add(p1);
persons.Add(new Person("Person2"));
Person p3 = new Person("Person3");
p3.Children.Add(new Person("Children1"));
persons.Add(p3);
persons.Add(new Person("Person4"));
persons.Add(new Person("Person5"));
tvTree.ItemsSource = persons;
}
}
public class Person
{
List<Person> children = new List<Person>();
string name;
public Person(string name)
{
this.name = name;
}
public string Name
{
get { return name; }
}
public List<Person> Children
{
get { return children; }
set { children = value; }
}
}
}
As expected no XAML code is written to handle the Children list so no sub TreeItemView is visible. How shall I implement that in my XAML code?

This one's going to appear a little bit magic right now. If you add ItemsSource="{BindingChildren}" to your HierarchicalDataTemplate definition, you'll automatically get the children added into the correct location. This turns your TreeView into this:
<TreeView Name="tvTree">
<TreeView.ItemTemplate>
<HierarchicalDataTemplate
ItemsSource="{Binding Children}"
DataType="{x:Type local:Person}">
<Grid>
<TextBlock Text="{Binding Name}" />
</Grid>
</HierarchicalDataTemplate>
</TreeView.ItemTemplate>
</TreeView>
