Different icon in WebDataTree when node expanded/collapsed
posted

Hi,

I'm new to Infragistics and i want to use the WebDataTree. I can build the tree and i want to show an icon near each node. This works via NodeSettings. But i want to show a different icon if the node is expanded or collapsed. Like showing an Folder-icon when the node is collapsed and an OpenFolder-icon if it is expanded.

What must i do to achieve that?

Thanks

Martin

    Hi Martin,

    Thank you for posting in the community.

    In this scenario I can suggest that you enable postback on NodeExpanded and NodeCollapsed. By handling the respective server-side events you can set the ImageUrl or the target node as needed. For instance:

    

        protected void WebDataTree1_NodeExpanded(object sender, Infragistics.Web.UI.NavigationControls.DataTreeNodeEventArgs e)
        {
            e.Node.ImageUrl = "~/add_disabled.gif";
        }

    Please let me know if this helps.
