Display Member Path wrong behavior

[Taher]

when using display member path proporty of the RadComboBox with a binding expression. it doesn't update the currently selected item display when the binding is changed. however when i open it's drop-down all the items are updated with the new value of the new display member path

<RadComboBox DisplayMemberPath={Binding Path=Language, Converter{StaticResource languageToProportyNameConverter}} ItemsSource="{Binding Path=Countries}"/>

Note: The right purposed behavior works fine in case of the silverlight ComboBox

<ComboBox DisplayMemberPath={Binding Path=Language, Converter{StaticResource languageToProportyNameConverter}} ItemsSource="{Binding Path=Countries}"/>

thanks for you help.

Hi George

Hello,

Now I understand. We are aware of this problem. Unfortunately, this is a limitation of the framework and we cannot implement it at this stage.
Sorry for any inconvenience caused.

George or someone at Telerik,



Does this limitation still apply in the latest versions of the SL controls because we are experiencing the same issue.  When the underlying value the DisplayMemberPath points to is updated the RadComboBox Selected Text is not updated even if we issue:



ctlRadComboBox.Rebind(RadComboBox.DisplayMemberPathProperty);



Can we manually change the SelectedText value from code behind?



Thanks...Bob Baldwin

Hi Bob,

Yes, this is still limitation in RadComboBox. However, you could change the selected text from code behind using the RadComboBox.Text property.

Hope this helps.
