Binding to IsExpanded - is it supported?

[Tomasz]

Hi,

I browsed the forum for the issue with binding to IsExpanded property and there is some confusion. Can you clarify current status?

More details:
TreeListView is used to show hierarchy of objects.

 

 

<telerik:RadTreeListView.ChildTableDefinitions

 

 

 

>

 

 

 

<telerik:TreeListViewTableDefinition ItemsSource="{Binding Children}"/>

 

 

 

</telerik:RadTreeListView.ChildTableDefinitions>

 

Children is notifying property of type IList<myclass>.

I'm attaching following Style to RowStyle property of treelistview.

 

 

<Style x:Key="TreeRowStyle" TargetType="telerik:TreeListViewRow">

 

 

 

<Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay}" />

 

</

 

 

Style>

 

Should it work or not?

Setting IsExpanded to fixed value 'true' doesn't help.

I'm using binaries version 2012.3.1404.1050

Hello,

With our internal build (version 2012.3.1321.40) we have introduced two new properties - IsExpandedBinding and IsExpandableBinding which can be used in your scenario. For example you can check our online demos.
 
Would you upgrade to a most recent version so that you could benefit from those properties?
