TreeView AfterLabelEdit - no work

[bob]

Hello,

the nodes in my tree view show a name and then a suffix. I want to be
able to edit the name using 'label edit' but I want the suffix to be
removed and then added after the edit. I try this with the events
AfterLabelEdit and BeforeLabelEdit but they don't do anything. The
following bit of code just has a tree view with some nodes and has
BeforeLabelEdit set to change the node text to 'editing':

private void treeView1_Befor eLabelEdit(obje ct sender,
System.Windows. Forms.NodeLabel EditEventArgs e)
{
e.Node.Text = "Editing";
}
But it doesn't do anything.

Any one have any ideas?

sorry about the long post

Thanks,

Bob

Do this in AfterLabel Edit event

private void treeView1_After LabelEdit(objec t sender,
System.Windows. Forms.NodeLabel EditEventArgs e)
{
string text = e.Label;
e.CancelEdit = true;
e.Node.Text = "Edited: " + text;

Thanks for your help Shak, your tip fixes the AfterLabelEdit event.

But what about the BeforeLabelEdit event, I still don't seem to be
able to change the text at the start of the edit operation.

Any ideas?

As Shakir once told me, try the OnClick() event.
