Virtual grid + add new row

[Hui Zhong]

When the data source (view) behind the virtual grid is inserted a new row, I used the grid.refresh(), and want to move the current cell to the new added row:
this.CurrentCell.MoveTo(GridRangeInfo.Row(newRowIndex ));

the new row data was partially displayed, some column cells data are missing. And the grid did not scroll to the current cell. Please help. Thanks.

Hui,

try calling

grid.Model.ResetVolatileData();
grid.UpdateScrollBars();

The call to ResetVolatileData will force the grid to callback into the QueryRowCount event which you probably have overriden in your code and where you return the new row count (including the newly added row ...)

It doesn''t work for me. ResetVolatileData did force grid to callback into the QueryRowCount event, and the grid row count did increase by 1.
But the data is still partially displayed and the scroll bar doesn''t work either.

Do you have any example for this scenario? For example, how to add one row in the virtual grid, and heightlight the added row in the grid.

Please use this attached sample code. It''s an example from your website. I added one button to add new records. click it, you will see the record was inserted, however, the scroll bar doesn''t work in this scenario. Thanks. >Hui, > >try calling > >

Hi Hui, Here is a small sample in which, a button handler adds a new row to a virtual grid. Let me know if that does not help. Best regards, Stanley
