SaveCellInfo + ResetVolatileData

[Hui Zhong]

I have one problem with SaveCellInfo()event for virtual grid. Please see the attached example code. Our intention is to change the one cell''s data in the SaveCellInfo() event, and change the another cell''s data in the datatable. And then call ResetVolatileData() to update the grid data. However, ResetVolatileData() not working. When you set a debug point at ResetVolatileData(), and test this function by going through this debug point. Then refresh is working in this scenario. Please instruct how to get ResetVolatileData() working in this case. Thanks.

Hi Hui,

The ResetVolatileData method is used to reset properties like the row count and column count. In order to display the changes in the datasource, the methods like refresh, refreshrange and invalidate are to be used.

For this scenerio, try setting the refreshcurrentcellbehaviour to refreshrow in the form load event to see if it helps or go for above mentioned methods in the savecellinfo event.
Below is the code snippet to resolve the issue

// In Form1_Load event
this.gridControl2.RefreshCurrentCellBehavior = GridRefreshCurrentCellBehavior.RefreshRow;

Best Regards,
Madhan.
