Hi,

The Grid does not have built-in support for tooltip. If you wish to have tooltip for a cell, you can put whatever HTML inside the cell that would display a tooltip (for example, instead of putting "cell data" in the cell, you can put "<div title='this is a tooltip'>cell data</div>" as the cell content). If you wish to have tooltip for a row, then you will have to handle the Grid's ClientSideOnItemOver to display tooltip with JavaScript (this is not as easy as it sounds, so if you do not already have the code to do it, then it probably won't be worth it).

Thanks!
