Grouping Issues

[Tony]

I have a RadGridView with an unbound Select column (checkbox). If I group by any field, I can select a checkbox to select the row and everything appears to work fine. If I then select another checkbox, all grouping collapses, and that record is not selected.  I can then expand the grouping and select the record. This process then repeats for each record I select.  I am using the latest version of the WinForms controls.

Thanks in advance,
Tony

I'm having the exact same problem.  What was the solution?  Thanks!

Here is the solution as provided by Jack at Telerik Support...

I found a solution for this issue. You should remove the specific filter expression when handling CellValidated event. Here is the work-around:

void radGridView1_CellValidated(object sender, CellValidatedEventArgs e)
{
    if (this.radGridView1.CurrentCell is GridCheckBoxCellElement)
    {
        foreach (FilterExpression filter in this.radGridView1.MasterGridViewTemplate.FilterExpressions)
        {
            if (filter.FieldName == ((GridViewDataColumn)this.radGridView1.CurrentColumn).FieldName &&
                filter.Predicates[0].Function == GridKnownFunction.NoFilter)
            {
                this.radGridView1.MasterGridViewTemplate.FilterExpressions.Remove(filter);
                break;
            }
        }
    }
}

As to our next release, it will be in November.
