out of the range

[Nietzsche]

Hi,
when I run this code
(when a oCol is a collection not empty):

private GridGroupingControl grdResult;
...

private void grdResult_TableControlCellButtonClicked(object sender, GridTableControlCellButtonClickedEventArgs e)
{
//
grdResult.TableControl.CurrentCell.Activate( e.Inner.RowIndex, 1, 0 );
//
oCol.RemoveAt(e.Inner.RowIndex-2);
//
grdResult.DataSource = null;
grdResult.DataSource = col;
grdResult.TableControl.CurrentCell.MoveTo(oCol.Count+1,0,0);
grdResult.TableControl.ScrollCellInView( grdResult.TableControl.CurrentCell.RowIndex, grdResult.TableControl.CurrentCell.ColIndex );
//
}

the following exception is raised on ".MoveTo(...)" :

Specified argument was out of the range of valid values.
Parameter name: Index was out of range. Must be non-negative and less than the size of the collection.

Waiting for one answer.

Thanks of everything.

Hi Nietzsche,

Based on the call stack it looks like there is a current record that was marked modified.

Does it help if you set

Table.CurrentElement = null;
- or -
Table.CurrentRecordManager.Navigate(null);
- or -
Table.CurrentRecordManager.Reset();

before you set the datasource to null.

I tried the solutions you proposed, but they doesn''t work.

I send a sample. If You delete the last record the exception raised.

Waiting for one answer.

Thanks of everything.

This code seems to delete the row fro me in your sample.

private void grdResult_TableControlCellButtonClicked(object sender, GridTableControlCellButtonClickedEventArgs e)
{
	e.TableControl.Table.GetCurrencyManager().Position -= 1;
	oCol.RemoveAt(e.Inner.RowIndex-2);
	grdResult.Engine.Table.TableDirty = true;
	grdResult.Refresh();
}
