Setting the checkboxes in the TreeViewAdv by selecting the labels

Hi, Is it possible to set the Checked flag of tree nodes by the user clicking on the label rather than the checkboxes? I have implemented it by listening for the tree AfterSelect events and setting the Checked property of the selected node but requires quite a bit of coordinated event handling complicated by different behaviour if the tree has just got focus. If not, it might be a good idea for the next release. Jeremy Dickson.

Hi Jeremy, TreeViewAdv contains methods that allow you to convert Control.MousePosition into a location inside the TreeViewAdv. If you handle MouseDown, you can use those methods to detect whether or not a label was clicked on and set the Checked property accordingly. The following code snippet demonstrates this: private void treeViewAdv1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e) { if (e.Button == MouseButtons.Left) { // get the point where the mouse was left clicked Point p = this.treeViewAdv1.PointToClient(Control.MousePosition); // get the node at the left click point TreeNodeAdv node = this.treeViewAdv1.PointToNode(p); if (node != null) { // see if the label was clicked on if (node.TextAndImageBounds.Contains(p)) { node.Checked = !node.Checked; } } } } Hope it helps.
