Multiple tree nodes remain highlighted.

[Bijender]

Hi,

I am using Telerik tree control inside the busy indicator. When user clicks on a tree node then busy indicator shows that some process is going on. But when user clicks on multiple tree node as soon as the busy indicator stops then multiple tree nodes become hightlighted. It creates ambiguity to user that which node was selected.

When I take out the Telerik tree view code from the busy indicator then Tree works fine.

Below is the code used.  I have attached the image as well.

 

 

 

 

 

<telerik:RadBusyIndicator x:Name="BusyInd" HorizontalAlignment="Center" Background="Transparent" VerticalAlignment="Center" BorderThickness="0" >

 

 

 

 

 

 

<

 

 

telerik:RadTreeView x:Name="locationTree" LoadOnDemand="locationTree_LoadOnDemand" VerticalAlignment="Top" Margin="0" Grid.Row="1" MinHeight="300" Width="Auto" Height="{Binding Height, ElementName=grdTree}" ExpanderStyle="{StaticResource ExpanderStyle1}" IsLineEnabled="True" Background="White" PreviewSelectionChanged="locationTree_PreviewSelectionChanged" SelectionChanged="locationTree_SelectionChanged">

 

 

 

 

 

 

 

 

 

 

<telerik:RadTreeView.ItemTemplate>

 

 

 

 

 

 

 

 

 

<telerik:HierarchicalDataTemplate ItemsSource="{Binding SubLocation}">

 

 

 

 

 

 

 

 

 

<StackPanel>

 

 

 

 

 

 

 

 

 

<TextBlock Text="{Binding LOCATION_ID}" />

 

 

 

 

 

 

 

 

 

</StackPanel>

 

 

 

 

 

 

 

 

 

</telerik:HierarchicalDataTemplate>

 

 

 

 

 

 

 

 

 

</telerik:RadTreeView.ItemTemplate>

 

 

 

 

 

 

 

 

 

</telerik:RadTreeView>

 

</

 

 

telerik:RadBusyIndicator>

Hi Bijender,

Which version of our products are you using? We did have such an issue but it was fixed for the official Q2 2011 release. I've attached my test project. Could you please take a look at it and let me know if I am missing anything. I'd be glad to further assist you.

Hello Bala,

 In databinding scenario, if your DataTemplate set for an ItemTemplate of the RadTreeView could be set like this:
<DataTemplate>
    <Grid>
          <TextBlock Text={Binding Name"}"/>
    </Grid>
</DataTemplate>
This way , when you want to ""highlight" particular RadTreeViewItem, you will be able to access the Grid by RadTreeViewItem.Header and set its Background property. Hope this is suitable for you.

All the best,
