Thank you for writing.
You can handle the RadGridView.ToolTipTextNeeded
event in order to assign a tooltip to a certain cell. In the event handler, you can specify the ToolTip.AutoPopDelay
in order to determine how long the tooltip remains visible if the pointer is stationary on a control with specified ToolTip
text. However, if you need to hide it programmatically, you can call the ToolTip.Hide
I hope this information helps. Should you have further questions I would be glad to help.
