c#: winforms: tooltip: how to delay tooltip.Show

I'm using winforms ToolTip class on a DataGridView (not tooltip of datagridview since I need custom formatting.)

And I call toolTip.Show() in DataGridView's CellMouseEnter event.

toolTip.Show() shows the the tooltip immediately and InitialDelay property is not working since I called toolTip.Show().

Is there another way to delay toolTip.Show() just like regular initaldelay.
