Hi

I'm trying to delete some rows from a grid. I use the following code (taken
from the help)

private void DeleteRows()

{

    int[] selectedRows = GridView.GetSelectedRows();

    if(selectedRows != null)

    {

        try

        {

            GridView.BeginUpdate();

            Array.Sort(selectedRows);

            for (int i=selectedRows.Length-1; i>=0; --i)

            {

                GridView.DeleteRow(selectedRows[i]);

            }

        }

        finally

        {

            GridView.EndUpdate();

        }

    }

}

I have a Grid with a DataSource with 3 rows. If I select row no. 1 and 3 in
that order and invokes the method, then I can't select the remaining row. I
get a DialogBox saying "Index was out of range. Must be non-negative and
less than the size of the collection. Parameter name: index Do you want to
correct the value ?".

If I select row no. 3 and then no. 1 there is no problem!

What am I doing wrong??



Thanks for your help!

Brian

After removing the 2 rows the FocusedRowHandle is 1 even though there is
only 1 row left in the grid and therefore should be 0.

Can anyone help me on this??

Hi Brian,

I've tried this code with the latest version (2.4.4) of the XtraGrid and it 
worked fine for me. Please check that you are using the latest version of 
the XtraGrid and if it still doesn't work, please send a sample project to 
our support team.
