Hi All,

I have a WebDataTree which I populate in the page_load on the server-side, all works well, but I am getting a problem where the NodeClick event seems to get fired multiple times.

The tree is defined as follows

<ig:WebDataTree ID="wdtCase" runat="server" Height="300px" Width="100%" 

    EnableConnectorLines="True" onnodeclick="wdtCase_NodeClick" 

    onselectionchanged="wdtCase_SelectionChanged">

    <AutoPostBackFlags NodeClick="On" SelectionChanged="Async" />

    <ClientEvents Initialize="InitializeHandler" NodeClick="NodeClickHandler" NodeCollapsed="NodeCollapsedHandler"

                    NodeCollapsing="NodeCollapsingHandler" NodeExpanded="NodeExpandedHandler" NodeExpanding="NodeExpandingHandler"

                    NodeHovered="NodeHoveredHandler" NodeUnhovered="NodeUnhoveredHandler" NodePopulated="NodePopulatedHandler"

                    NodePopulating="NodePopulatingHandler" CheckBoxSelectionChanged="NodeCheckBoxSelectionChangedHandler"

                    ActivationChanged="NodeActivationChangedHandler" ActivationChanging="NodeActivationChangingHandler"

                    SelectionChanged="NodeSelectionChangingHandler" SelectionChanging="NodeSelectionChangingHandler" />

    <AjaxIndicator AltText="Async post" />

</ig:WebDataTree>

Nothing out of place there, then the NodeClick event is

 protected void wdtCase_NodeClick(object sender, Infragistics.Web.UI.NavigationControls.DataTreeNodeClickEventArgs e)

        {

            // Raise the NodeClick event out.

            if(this.NodeClicked != null) 

            {

                // do stuff here

            }

        }

But the event is called multiple times, not just once. Has anyone got any suggestions?

Many thanks
