Tooltips
Updated over 6 months ago
There are two ways to assign tooltips to RadButton, namely setting the ToolTipText property of the ButtonElement, or as in most of the RadControls by using the ToolTipTextNeeded event of RadButton. It is necessary the ShowItemToolTips property to be set to true which is the default value.
Setting the ToolTipText property
C#
this.radButton1.ButtonElement.ToolTipText = "I am a button";

Setting tool tips in the ToolTipTextNeeded event
C#
private void radButton1_ToolTipTextNeeded(object sender, Telerik.WinControls.ToolTipTextNeededEventArgs e)
{
e.ToolTipText = "Click me";
}

The ToolTipTextNeeded event has higher priority and overrides the tool tips set in the ToolTipText property.
