helo everybody and thanks again for taking your time to answer my simple questions.

I am using a treeview control in which the nodes have a check box (so far all built in finctionality of the treeview).

How can I respond when a user checks or unchecks a check box? It is not clear how I can raise an evemt for that particular event

Thank you

Marc

hi,

  there is a default event available to capture this change, ie. "TreeNodeCheckChanged" event. u can apply this event in a code behind file (file with .vb extension) by selecting this event from the methods listed there, then u can add ur own validations there,

  something like this,

If e.Node.Checked = True Then
  urcode
Else
  urcode
End If

Hope it helps.
