Detecting mouse click on a node''s image

Is there a way to detect if the image on the left side of the node''s text was clicked on? Thanks

Hi Mike, You could do so by handling the TreeViewAdv''s MouseUp event as shown below : private void treeViewAdv1_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e) { TreeNodeAdv node = this.treeViewAdv1.SelectedNode; Point imgpt = new Point (node.TextAndImageBounds.X, node.TextAndImageBounds.Y); Size imgSize = new Size(this.imageList1.ImageSize.Width, this.imageList1.ImageSize.Height); Rectangle imgrec = new Rectangle(imgpt, imgSize); Point clickpt = new Point(e.X, e.Y); if (imgrec.Contains(clickpt)== true) { Console.WriteLine("Clicked on " + node.Text + "''s left image"); } } I have modified the TreeViewAdvImageOverlayingDemo sample accordingly and have attached it here. Please refer to it and let me know if this works for you. Regards, Guru Patwal Syncfusion, Inc.

Your sample does not work since the SelectedNode is not yet set to the node the user clicked on. The code below seems to work: Point clickpt = new Point(e.X, e.Y); TreeNodeAdv node = this.treeViewAdv1.PointToNode( clickpt ); string aText; aText = node.Text; Point imgpt = new Point (node.TextAndImageBounds.X, node.TextAndImageBounds.Y); Size imgSize = new Size(this.imageList1.ImageSize.Width, this.imageList1.ImageSize.Height); Rectangle imgrec = new Rectangle(imgpt, imgSize); if (imgrec.Contains(clickpt)== true) { Console.WriteLine("Clicked on " + node.Text + "''s left image"); }
