QueryCellInfo event firing when i move the mouse over cells . .

I keep getting QueryCellInfo events when i am moving the mouse over cells. I am not moving any scrollbars or moving the size of the form or screen. I am not clicking anywhere. i am simply moving my mouse around the current grid. Is this a bug in the grid ? thanks, ak

No. This is by design. The grid needs the cell style to do hit testing as the mouse moves.

is there anyway to disable or turn this off this because it seems like it is wasting a lot of resources. >No. This is by design. The grid needs the cell style to do hit testing as the mouse moves.

You can use the technique shown in this sample. \Syncfusion\Essential Studio\3.2.1.0\Windows\Grid.Windows\Samples\Performance\OneTimeOnlyQueryCellInfo

It says in the sample that this sample is good for a: "data container that is optimized for non-virtual grids with a smaller number of rows where QueryCellInfo event is only wanted to be called once for a cell and not multiple times." i am confused.. i AM using a virtual grid with about 50 - 100 rows. i only want the QueryCellinfo to get called when i explicitly call a refresh on a cell or range. not any other time. (for example mouse move over) . . any ideas?? thks, ak >You can use the technique shown in this sample. > >\Syncfusion\Essential Studio\3.2.1.0\Windows\Grid.Windows\Samples\Performance\OneTimeOnlyQueryCellInfo

That sample is the only way you can avoid QueryCellInfo from being raised continuously.
