I added two unbound check boxes to my grid.

            UltraGridColumn defaultPrice = e.Layout.Bands[0].Columns.Add(DEFAULTPRICEOVERRIDE, "Override Default Pricing");
            defaultPrice.DataType = typeof(bool);
            defaultPrice.CellActivation = Activation.NoEdit;

            UltraGridColumn deleteProduct = e.Layout.Bands[0].Columns.Add(DELETEPRODUCT, "Delete Product from Grid?");
            deleteProduct.DataType = typeof(bool);
            deleteProduct.CellActivation = Activation.NoEdit;

I do not want the two boxes to edited unless the row is activated by a third checkbox that is bound.

I am setting the Activation to AllowEdit, however I still cannot check the boxes.  What am I missing?

       private void ugProductSelection_CellChange(object sender, CellEventArgs e)
        {
            // Get the grid.
            UltraGrid grid = (UltraGrid)sender;

            // Get the last UIElement entered.
            Infragistics.Win.UIElement lastElementEntered = grid.DisplayLayout.UIElement.LastElementEntered;
           
            // If there is no element, return.
            if (lastElementEntered == null)
                return;

            // Get the cell that the element is in.
            UltraGridCell cell = lastElementEntered.GetContext(typeof(UltraGridCell)) as UltraGridCell;

            // If there is no cell, return.
            if (cell == null)
                return;

            if (cell.Column.ToString() == PRODSELECTED)
            {
                UltraGridRow row = lastElementEntered.GetContext(typeof(UltraGridRow)) as UltraGridRow;
               
                if (cell.Text == "True")
                {
                    row.Cells[DEFAULTPRICEOVERRIDE].Activation = Activation.AllowEdit;
                    row.Cells[DELETEPRODUCT].Activation = Activation.AllowEdit;
                }
                else
                {
                    // User set the Product Selected box to unchecked, so make sure the other two
                    // boxes are unchecked.
                    row.Cells[DEFAULTPRICEOVERRIDE].Value = false;
                    row.Cells[DELETEPRODUCT].Value = false;
                    row.Cells[DEFAULTPRICEOVERRIDE].Activation = Activation.Disabled;
                    row.Cells[DELETEPRODUCT].Activation = Activation.Disabled;
                }
            }
        }
