Hi,

Can anyone tell me how to capture the action button being pressed for a TreeView control?  Neither the Click or KeyDown / KeyPress events seem to pick this up!

Cheers,

Ben

Click is not supported but AfterSelect is.

Try this code as an example. it requires a textbox and treeview to work of course.

private void treeView1_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
{
switch((e.Action))
   {
   case TreeViewAction.ByKeyboard:
      textBox1.Text = "Keyboard";
      break;
   case TreeViewAction.ByMouse:
      textBox1.Text = "Mouse";
      break;
   case TreeViewAction.Collapse:
      textBox1.Text = "Treview Collapsed";
      break;
   case TreeViewAction.Expand:
      textBox1.Text = "Treview Expanded";
      break;
   case TreeViewAction.Unknown:
      textBox1.Text = "Unknown";
   break;
   }
}

Thanks for the response komplex

I got round the problem a different way - I used
OpenNetCFs ApplicationEx - it allows you to trap specific windows messages - something that MS should have included
