We’re loading the tooltip text in the gantt_OnTimeItem_Hoover event. This works fine, but the tool tip appears too quickly. How and where should I set the toolTip.InitialDelay? Every way that I tried to set this property has no effect.
I tried the sample Gantt_TimeItems and you are correct, the tooltip shows directly…
This is a bit odd since these values are set on the tooltip component:
this.toolTip1.AutomaticDelay = 2000;
this.toolTip1.AutoPopDelay = 20000;
this.toolTip1.InitialDelay = 2000;
this.toolTip1.ReshowDelay = 2000;
It appears to be some un-document feature that if you call toolTip1.SetToolTip(gantt1.TimeItemArea,newTooltipText); with the same text, the tooltip show directly; ignoring the InitialDelay etc…
Work around is to avoid setting the same text twice:
Then it started to behave as expected (Only tested in VS2006 CLR20).
