Grid Control CurrentCell not reset when RowCount = 0

[Julie Levy]

Hi -
I have a situation where the only row of a GridControl is removed using Rows.RemoveRange and the CurrentCell object is still representing a cell in that row (which was the current cell when the row was removed). This is causing problems in our code in keypress events (where the rowindex and columnindex are still set to that cell) as well as the CurrentCellChanged event which is firing (see my attached screenshot). The Renderer is null so i can check for that in the event, but i'm wondering if there's something that can be done to null out the CurrentCell so that the events don't fire.

I don't know if this is a bug or due to something i'm doing in code. It's present in both versions 5.2 (VS2005) and 7.4 (VS2008).
Thanks,
Julie

Hi Julie,

Thank you for your interest in Syncfusion products.

While removing the rows using RemoveRange() method, the current cell renderer cannot get refreshed and notifies the old indexes. Hence, we can make use of MoveTo() method after removing the range to force the current cell to refresh.

Here is the code snippet regarding this,

          this.gridControl1.Rows.RemoveRange(0, this.gridControl1.RowCount);
          if (this.gridControl1.RowCount == 0)
          {
              this.gridControl1.CurrentCell.MoveTo(0, 0, GridSetCurrentCellOptions.SetFocus); //refresh the current cell

          }

Please refer the following sample which illustrates the above.
