The issue happens because Data Grid 2 or one of its parent containers may have Overflow : hidden or Overflow: auto
When the Tooltip opens outside the grid cell, the parent container clips the tooltip, so only part of it is visible.
I hope this works, if not solved can you please attach the screenshots. So that i can understand more clear.
Hi,
Could you please attach a clear screenshot showing the complete Tooltip widget and the DataGrid 2 area where the tooltip is getting cut off?
The current screenshot doesn't not vissible.
Once you share a proper screenshot, I can take a look and suggest the appropriate fix.
