Hi all,
I searched this forum and learned from other posts about how to add custom javascript that will be run when the treenode is clicked.
But now I want to add custom javascript that will be run when the expand button (which is next to every treenode that has childs) is clicked.
I examined the source html code and discovered that if the expand button is clicked, it first calls the ASP.NET-generated TreeNode_Populate javascript function. I want it to call my custom javascript function before it calls this ASP.NET-generated function.
Could somebody please suggest what the possible solutions are? Thanks a lot.
