Here's a weird one. I've got a RadTreeView that works fine and has a few client-side EventHandlers hooked up.  However, when I reload the RadTreeView using a CallBack, suddenly no EventHandlers work.  As a matter of fact, nodes won't even expand/collapse, so it's not just that the custom EventHandlers I've added don't work, even the built-in ones are gone.

What's going on and how do I stop it?

                                                        <telerik:RadTreeView  
                                                            RunAt="server"  
                                                            ID="RadTreeView1"  
                                                            OnClientNodeClicking="nodeClicking" 
                                                            EnableDragAndDrop="true" 
                                                            OnNodeDrop="RadTreeView1_HandleDrop" 
                                                            EnableDragAndDropBetweenNodes="true"
                                                            <DataBindings> 
                                                                <telerik:RadTreeNodeBinding  
                                                                    TextField="listitemName" 
                                                                    ValueField="listitemID" 
                                                                    /> 
                                                                <telerik:RadTreeNodeBinding  
                                                                    Depth="0"  
                                                                    TextField="listitemName"  
                                                                    ValueField="listitemID" 
                                                                    Expanded="true" 
                                                                    CssClass="rootNode"  
                                                                    /> 
                                                            </DataBindings> 
                                                        </telerik:RadTreeView>

Hello Jesse,

Could you please check whether you receive any javascript errors? How exactly the treeview is reloaded? Please send us more details so we to be able to reproduce the problem. Thanks

I was reloading it with a ComponentArt CallBack control.  When I switched to the Telerik RadAjax method of reloading, the problem went away.  Maybe ComponentArt has a sneaky way of sabotaging embedded Telerik controls (and vice versa?)!
