Hello I am trying to use a RadComboBox that has a RadTreeView inside of it for a filtering column on a RadGrid.  I am able to use the CustomFilteringColumn.cs example to use a dropdown and then modify it to use a RacomboBox just fine.  However, when I use the combo with the tree inside it I am unable to get the control to fire the combo_SelectedIndexChanged event until the control has lost focus, once the control has lost focus then it will perform the filter just fine.  I also am able to modify it so that I can fire a NodeClick event on the tree and the filter will perform just fine except that in this case I get a full postback, and I don't want that either.  So I was hoping there was a way to execute the FireCommandEvent without having a full postback and without having to lose focus.

Is there an example of this that might be helpful or if anyone has any idea on how to this it would be greatly appreciated.

Thank you

Aaron

I was able to fix this problem by attaching the RadComboClosed client side function and then cause a postback using __doPostBack, and passing the sender.get_id() and the value of the node that was picked after determining the value in the same function.
