Assign RadScreenTip to nodes
Updated on May 7, 2026
In order to assign RadScreenTip to the nodes of RadTreeView you should use the ScreenTipNeeded event.
If the item which needs a ScreenTip is a TreeNodeElement, you set the necessary properties of the globally instantiated RadOffice2007ScreenTip:
C#
RadOffice2007ScreenTipElement screenTip = new RadOffice2007ScreenTipElement();
Size size = new Size(120, 70);
Padding pad = new Padding(2);
void radTreeView1_ScreenTipNeeded(object sender, Telerik.WinControls.ScreenTipNeededEventArgs e)
{
TreeNodeElement node = e.Item as TreeNodeElement;
if (node != null)
{
screenTip.MainTextLabel.Image = node.ImageElement.Image;
screenTip.MainTextLabel.TextImageRelation = TextImageRelation.ImageBeforeText;
screenTip.MainTextLabel.Padding = pad;
screenTip.MainTextLabel.Text = "This is " + node.ContentElement.Text;
screenTip.MainTextLabel.Margin = new System.Windows.Forms.Padding(10);
screenTip.CaptionLabel.Padding = pad;
screenTip.CaptionLabel.Text = node.ContentElement.Text;
screenTip.EnableCustomSize = true;
screenTip.AutoSize = false;
screenTip.Size = size;
node.ScreenTip = this.screenTip;
}
}
