I have a DataBoundGrid with a ComboBox column and I would like the user to be able to select mutiple rows then when they change the option in the combo box in one of the selected rows, all of the other selected rows change their options to match. That would save my users a lot of hassle. Could you give me any pointers please? Thanks, Mark

You can try doing this in the CurrentCellChanged event.
private void gridDataBoundGrid1_CurrentCellChanged(object sender, System.EventArgs e)
{
	GridCurrentCell cc = this.gridDataBoundGrid1.CurrentCell;
	if(cc.ColIndex == 2) //id combo column somehow
	{
		GridRangeInfo range = this.gridDataBoundGrid1.Selections.Ranges.ActiveRange;
		if(!range.IsEmpty && range.Contains(cc.RangeInfo))
		{
			range = range.IntersectRange(GridRangeInfo.Col(cc.ColIndex));
			cc.ConfirmChanges(true);
			int position = this.gridDataBoundGrid1.Binder.CurrentPosition;
			this.gridDataBoundGrid1.Model.ChangeCells(range, cc.Renderer.ControlText);
			this.gridDataBoundGrid1.Binder.SetCurrentPosition(position, true);
		}
	}
}

Thanks Clay, that worked a treat. The code works great for block selections i.e. rows 1 though 6 but is there a way to expand the code to work for disjointed selections ie. selected rows 1,4,8,33 when the user selects via control+click. Is there a way to loop through the selected ranges in turn? Thanks, Mark

Instead of GridRangeInfo range = this.gridDataBoundGrid1.Selections.Ranges.ActiveRange; that only looks at the active range, you could try the same code in this type of loop foreach(GridRangeInfo range in this.gridDataBoundGrid1.Selections.Ranges) { //same code }
