Hi,

I have the following:

Request("Id") => Which represents the ID of the TreeNode.

I want to get the TreeNode from this. I have used the following syntax but never works for me:

Dim node As TreeNode = CType(FindControl(Request("Id")), TreeNode)

Error:

Value of type 'System.Web.UI.Control' cannot be converted to 'System.Web.UI.WebControls.TreeNode'

Can you please give me the correct syntax ?

Thanks

is sender one of the inputs to your procedure?
that gives you a reference that will either be direct or that you should be able to drill through to what you need.

TreeNode unlike other controls does not inherit from System.Web.UI.Control. It inherits direct from System.Object only. So you can't find it using FindControl. It also does not have an ID property. You will have to go into the TreeView collection and search for it.
