Changing Grid.RowCount in Async Event

Hello!
I change Grid.RowCount in async event but it doesn't work, RowCount is changing only after page reload. What am I doing wrong?

Please make sure you call AsyncUpdateAllCells after the RowCount has changed and ShowRowsAlways is True.

I localized the problem. When the form executed for the first time, it executed in the synchronous mode and RowCount is set to the certain value, say, 15. Subsequent async calls update the grid, but it is updated only if RowCount <= 15, i.e. you can't specify the value greater then the value set in the previous sync call.

This is a limitation of the IWAdvWebGrid control.

The initial RowCount value can only by decreased and not increased on subsequent async calls.
