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

Platform: WinForms |
Control: TreeViewAdv |
Published Date: April 30, 2011 |
Last Revised Date: February 6, 2020

Tooltip

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
