Hi,

There's no way to change this on the tooltips built-in to the grid. The tooltip delay is a system setting.

If you need to control the amount of time to tooltip displays, then you will need to provide your own tooltips in the grid. You could use the inbox ToolTip class, or the Infragistics UltraToolTipManager.

If you want to use UltraToolTipManager, I recommend that you check out one of the samples that installs with NetAdvantage (assuming you chose to install them when you installed).The sample is called "ToolTips With Context" and you can usually find it in a folder something like this:
