I have a List View which I am populating with Labels via code. When the user clicks the label I want to handle the MouseDown event, but it doesn't fire. The preview mouse down does fire.
I understand there is something here about routing / bubbling events which I guess is going to the issue I'm hitting, this is a concept I'm yet to grasp.
I cannot use the preview event as this does not contain the object I need (the label information does not get assigned until the second click of the label, so I assume I need the MouseDown and not the preview)
Appreciate your time.
XAML
<telerik:RadTabItem x:Name="Media" Header="Media" Height="22" Width="100">
<Grid x:Name="ListboxMedia">
<ListView x:Name="ListViewImages" HorizontalAlignment="Left" Height="303" Margin="697,10,0,0" VerticalAlignment="Top" Width="178" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Auto" IsTabStop="True" TabIndex="3" MouseDown="ListViewImages_MouseDown" PreviewMouseDown="ListViewImages_PreviewMouseDown">
<ListView.View>
<GridView>
<GridViewColumn x:Name="ListViewImageColumn" Header="Images" Width="178" />
</GridView>
</ListView.View>
</ListView>
<Button x:Name="BtnUpload" Content="Upload" Height="24" Margin="809,318,38,0" VerticalAlignment="Top" Click="BtnUpload_Click"/>
<Button x:Name="BtnDownload" Content="Download" Height="24" Margin="728,318,109,0" VerticalAlignment="Top"/>
<Image x:Name="ImageViewPort" HorizontalAlignment="Left" Height="293" Margin="21,20,0,0" VerticalAlignment="Top" Width="581"/>
</Grid>
</telerik:RadTabItem>
Method which populates Labels into ListViewImages
void PopulateMedia()
{
var collectImages = new Media().CollectMediaForAsset(_assetId);
int i = 1;
foreach (var collectImage in collectImages)
{
var label = new Label();
label.Tag = collectImage.FileName;
label.Content = "Image" + i.ToString();
ListViewImages.Items.Add(label);
i++;
}
}
Handlers
private void ListViewImages_MouseDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
Debug.WriteLine("Clicked Down"); //does not work
}
private void ListViewImages_PreviewMouseDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
Debug.WriteLine("Clicked Preview"); //works
}
Used selection changed event instead
