Problem with the RadTreeView and Loading on demand

[frederic szymczak]

I am using the RadTreeView with the last version of Telerik dll, for Silverlight 4 but I have a strange comportement.
I am using LoadOnDemand. The Loading Panel never disappears.
Also, when I click the first time on an item, the children don't appear. They appear only when I click again.

Do you have an idea of this problem ?

<

 

Border x:Name="BorderBottomLeftPanel" Grid.Row="2" Style="{StaticResource BorderContentPanelStyle}">

 

 

 

<telerikNavigation:RadTreeView

 

 

Name="treeView"

 

 

Margin="2,10,2,10"

 

 

IsExpandOnDblClickEnabled="True"

 

 

IsExpandOnSingleClickEnabled="False"

 

 

ItemContainerStyle = "{StaticResource MyRadTreeViewItemStyle}"

 

 

Foreground="{StaticResource RadTreeViewForegroundBrush}"

 

 

ExpanderStyle="{StaticResource ExpanderStyle1}"

 

 

IsLoadOnDemandEnabled="True"

 

 

LoadOnDemand="RadTreeView_LoadOnDemand"

 

 

MouseLeftButtonUp="RadTreeView_MouseLeftButtonUp"

 

 

Selected="RadTreeView_Selected">

 

 

 

</telerikNavigation:RadTreeView>

Thank You,

Hi frederic szymczak,

Could you please find the attached project and let us know if it satisfies you. The single-click expand could be achieved with setting the IsExpandOnSingleClickEnabled property to true. On the other hand, the loading animation ( if this is what you had in mind ) stops when you set      

clickedItem.IsLoadingOnDemand = false;

supposing the clickedItem is the RadTreeViewItem that you wish to load new children on demand ( that you`ve clicked). 
If this doesn`t fit in  your scenario, we would highly appreciate if you can send us a sample that demonstrates the issue you have come up with. You can also modify the attached project and send it back. Thank your for your cooperation in advance.


Best wishes,
