Yes, that trick ought to work! I verified that your code works with a slightly modified XAML (I used SilverLight 4):
<Image Source="..." MouseLeftButtonDown="editText_MouseLeftButtonDown" Tag="{Binding ElementName=UserNameTB}"/>
<Image Source="..." MouseLeftButtonDown="editText_MouseLeftButtonDown" Tag="{Binding ElementName=AddressTB}"/>

If I were doing this, I'd have a collection containing the details of the image, and a text item representing the text you want to display in the TextBlock. Then, I'd bind to this using something like a ListView.
In other words, I'd use MVVM to cope with this. I suggest that you have a look into this, and simplify the problem hugely.

Sounds like a newbie question. But can't help my self for already an hour.
I've Silverlight application with tabs and don't want to put all code in one large file. So I have made single UserControls and now I want to put them into the tab control.
<telerik:RadWindow xmlns:my="clr-namespace:UserEditorApp" x:Class="UserEditorApp.UserDetailsWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk"
mc:Ignorable="d" xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" Height="500" Width="750" Header="User details">
<Grid>
<StackPanel Orientation="Vertical">
<telerik:RadTabControl x:Name="rowDetailsTabControl" ReorderTabRows="False" >
<!-- User Details tab -->
<telerik:RadTabItem x:Name="UserDetailsTab" Header="Benutzer Details">
<StackPanel>
<my:UDW_Details /> <!-- how can I add the control here? -->
</StackPanel>
</telerik:RadTabItem>
</telerik:RadTabControl>
<StackPanel>
</Grid>
</telerik:RadWindow>
I can't see anything in the designer. Can somebody help me out of this?
Thanks!

StackPanels size to the size of the content. In your case, the size is 0x0, so you don't see anything.
You need to have your d namespace defined in the my:UDW_Details XAML and then add:
d:DesignWidth="300" d:DesignHeight="300"
to have a design time width and height.
or you can stub in design time data. Either way works.

1) Dont shout.
2) You can do this. Loop through the items inside an accordion and then remove items from it (or add new items to it).
Sample here[^].
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.

I have a treeview with a Template
The treeviewitem has an event handler. I want to access the parent treeviewitem from here. How can I achieve this.
End Goal - User can select a node and delete it.
Template
<br />
<sdk:HierarchicalDataTemplate x:Key="TreeViewMainReadTemplate" ItemsSource="{Binding Children}"><br />
<TextBlock Text="{Binding Text,Mode=TwoWay}" <br />
MouseLeftButtonDown="TreeViewMain_MouseLeftButtonDown"></TextBlock><br />
</sdk:HierarchicalDataTemplate><br />
TreeView
<br />
<sdk:TreeView Name="TreeViewMain" <br />
ItemTemplate="{StaticResource TreeViewMainReadTemplate}" <br />
Width="400" Height="400" ><br />
</sdk:TreeView><br />
Event Handler Where I want to access parent
<br />
private void TreeViewMain_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)<br />
{<br />
}<br />
Binding Data Class
<br />
public class Node<br />
{<br />
private String text;<br />
private ObservableCollection<Node> children;<br />
public ObservableCollection<Node> Children<br />
{<br />
get{ return children;}<br />
set{ children = value;}<br />
}<br />
<br />
public String Text { get { return text; } set { text = value; } }<br />
<br />
public Node(String text)<br />
{<br />
Children = new ObservableCollection<Node>();<br />
Text = text;<br />
}<br />
<br />
public void Add(Node node)<br />
{<br />
children.Add(node); <br />
NotifyPropertyChanged("Children");<br />
}<br />
<br />
public void Delete(Node node)<br />
{<br />
children.Remove(node);<br />
NotifyPropertyChanged("Children");<br />
}<br />
<br />
public event PropertyChangedEventHandler PropertyChanged;<br />
<br />
private void NotifyPropertyChanged(String info)<br />
{<br />
if (PropertyChanged != null)<br />
{<br />
PropertyChanged(this, new PropertyChangedEventArgs(info));<br />
}<br />
}<br />
}<br />

'sender' should be your Node object. You can then do something like:
Node node = sender as Node;
TreeViewItem tvi = ItemContainerGenerator.ContainerFromItem(node) as TreeViewItem;
You need to be careful here though because the WPF treeview is virtualized, so the TreeViewItem objects come and go as you scroll, collapse, etc. Its possible that ItemContainerGenerator.ContainerFromItem(node) will return null.

Thanks SledgeHammer01
I was just able to do this using TreeViewExtension part of the silverlight tookit.
TreeViewItem selectedTreeViewItem =
TreeViewExtensions.GetContainerFromItem(TreeViewMain, selectedNode);
if (selectedTreeViewItem != null)
{
TreeViewItem selectedTreeViewItemParent =
TreeViewExtensions.GetParentTreeViewItem(selectedTreeViewItem);
Also thankyou for your suggestions about binding the treeview data. I am doing that, and my life's much easier

And what does any of this have to do with Silverlight or WPF?

[EDIT]Issue below is solved. Somehow, for some reason, the properties indicating the binding needed to be in uppercase. I was under the impression that oracle was caseINsensative on this point? If anyone can elaborate, please do, because honestly, I don't understand.
[/EDIT]
I have a listview which ItemsSource is set from a dataset. I verified its contents and affter the assigment this property has the correct values.
In my XAML I then defined the GridViewColumns by binding the object-properties to the corresponding column in the grid. A prototype with MS Access worked perfectly. Now we moved to Oracle and changed one column from string to a datetime. To tackle this, I made a valueconverter.
Problem is, for some reason, the grid stays empty. No errors. the Items.Count shows there are items, but they don't show up in the grid. I can also select each row. In addition a breakpoint in the valueconverters classes don't break for some reason.
I'm pretty sure it's or the valueconverter or the XAML that's wrong, but after staring at it for 2 hours and googling I couldn't find my problem.
Does someone recognize this issue (it must be something small and stupid I'm overlooking)? Many thanks !
here's the XAML code:
<ListView Name="lv_logs" ItemsSource="{Binding}" FontSize="12">
<ListView.View>
<GridView>
<GridViewColumn Header="DateTime">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock VerticalAlignment="Center" Margin="5,0,0,0" Text="{Binding Path=logdts, Converter={StaticResource dts_valueconverter}}"></TextBlock>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Type">
<GridViewColumn.CellTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Image Source="{Binding Path=logtype, Converter={StaticResource logtype_valueconverter}}" Height="20" Width="20"/>
<TextBlock VerticalAlignment="Center" Margin="5,0,0,0" Text="{Binding Path=logtype}"></TextBlock>
</StackPanel>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Actor">
<GridViewColumn.CellTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Image Source="{Binding Path=logactor, Converter={StaticResource logactor_valueconverter}}" Height="20" Width="20"/>
<TextBlock VerticalAlignment="Center" Margin="5,0,0,0" Text="{Binding Path=logactor}"></TextBlock>
</StackPanel>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Application" DisplayMemberBinding="{Binding Path=logmodule}"></GridViewColumn>
<GridViewColumn Header="Machine" DisplayMemberBinding="{Binding Path=logmachine}"></GridViewColumn>
<GridViewColumn Header="Message" DisplayMemberBinding="{Binding Path=logmessage}"></GridViewColumn>
</GridView>
</ListView.View>
</ListView>

Hello,
When i wrote a "Source" property as full path "C:\aaa\aaa\aaa\aa\fileName" i do hear the sound, but when i'm trying to set the path using the resources, it doesn't work (no sound), i've marked build actions of the media file as "resources". and in source i wrote /namespace;component/Resources/filename
What i'm doing wrong here ?
thanks

you mean by /UIapp;component/Resources... didn't work still no sound
|
|
|
|

No that's not what I mean.
I mean that you CAN'T use Pack Uri for MediaElement.Source, therefor any syntax of Pack Uri you'll use won't work.
If you still wish to embed the wave/mp3 file as a resource, please re-read my previous answer for a workaround.
Thanks
Omer

just to make it clear,
you wrote "as you suggested"
what I suggested ?
the URI way, and the full path name way
|
|
|
|

"as you suggested" means NOT embedding the sound file in the assembly by using build action "content" and "copy if newer", and setting the Source property to a full or relative path, as your first attempt.
e.g.: \Soundfiles\myfile.wav

Hello,
At present I have visual web developer 2010 express which I use for silverlight development.
Now I would like to instal the visual c# 2010 express for WPF development.
During the install I get the following error:
The following component could not be downloaded:
.net framework 4 multi-targeting pack
Any thoughts on how to solve this please?
|
|
|
|
|

Try installing .Net framework 4 before you try to install C# 2010 express.
