How do I introduce a delay before the TreeViewAdv's Tooltip or HelpText popups are displayed ?

Platform: WinForms |
Control: TreeViewAdv |
Published Date: April 30, 2011 |

You could achieve this feature by getting hold of the ToolTipControl and HelpTextControl associated with the TreeViewAdv, and handling their BeforePopup events as shown below :

C#

this.treeViewAdv1.ToolTipControl.BeforePopup += new CancelEventHandler (TooltipBeforePopup_EventHandler);

this.treeViewAdv1.HelpTextControl.BeforePopup += new CancelEventHandler (TooltipBeforePopup_EventHandler);

private void TooltipBeforePopup_EventHandler (object sender, CancelEventArgs e)

{

Thread.Sleep(delay);

}

VB

Me.treeViewAdv1.ToolTipControl.BeforePopup += New CancelEventHandler (TooltipBeforePopup_EventHandler)

Me.treeViewAdv1.HelpTextControl.BeforePopup += New CancelEventHandler (TooltipBeforePopup_EventHandler)

Private Sub TooltipBeforePopup_EventHandler(ByVal sender As Object, ByVal e As CancelEventArgs)

' Introduce any desired delay here

Thread.Sleep(delay)

End Sub
