Tooltips
There are two ways to assign tooltips to RadCheckBox, namely setting the ToolTipText property of the ButtonElement, or as in most of the RadControls by using the ToolTipTextNeeded event of RadCheckBox. It is necessary the ShowItemToolTips property to be set to true which is the default value.
Setting the ToolTipText property
this.radCheckBox1.ButtonElement.ToolTipText = "CheckBox tool tip";
Me.radCheckBox1.ButtonElement.ToolTipText = "CheckBox tool tip"
Setting tool tips in the ToolTipTextNeeded event
private void radCheckBox1_ToolTipTextNeeded(object sender, Telerik.WinControls.ToolTipTextNeededEventArgs e)
{
e.ToolTipText = "I am a checkbox";
}
Private Sub radCheckBox1_ToolTipTextNeeded(sender As Object, e As Telerik.WinControls.ToolTipTextNeededEventArgs)
e.ToolTipText = "I am a checkbox"
End Sub
The ToolTipTextNeeded event has higher priority and overrides the tool tips set in the ToolTipText property.
