4 QueryCellInfo on refresh

[Kamil Dworakowski]

Hi,

When I attach a handler for QueryCellInfo event, and set float cells mode like this:

grid.Model.Options.FloatCellsMode = GridFloatCellsMode.BeforeDisplayCalculation

the handler is called four times for each cell on a refresh. We have already figured out that surrounding it with Begin- and EndUpdate takes it down to two. How do we take it down to 1 call per cell though?

See the attachment for repro. It needs to be run with ironpython interpreter, and need to edit the PATH_TO_SYNCFUSION_DLLS constant inside the script to point to the right directory.

Kamil Dworakowski

If I understand you correctly, you advise me to add a cacheing level on my own. Thanks anyway.

Hi Kamil,

Thank you for the update.

Sorry for the delay. In that kind of case base.QueryCellInfo event calling is prevented when cell not contains in GridControl visible range.

To be more clear the QueryCellInfo event is only triggered by the grid for a particular cell, whenever the cell information is needed by GridControl.

Please let me know if you have any other concerns.
