Hi Team,

we are using ultrawingrid for our development. We have a requirement to select rows across the bands when user uses the shift key + mouse down to a row all the rows in either first band or second band should be selected if the first band is expanded.

I tried doing with mouse event but it is not giving me the correct results. Is there a better way to handle this kind of things as the standard functionality is not allowing me to select the rows across bands.

 private Boolean ShiftKey, ControlKey;
        private UltraGridRow InitialRowSelected = null;

        private void ultraGrid1_KeyDown(object sender, KeyEventArgs e)
        {
            ShiftKey = false;
            ControlKey = false;
            switch(e.KeyCode)
            {
                case Keys.ShiftKey:
                    ShiftKey = true;
                    break;
                case Keys.ControlKey:
                    ControlKey = true;
                    break;
            }
        }
        
private void ultraGrid1_MouseDown(object sender, MouseEventArgs e)
        {
            Infragistics.Win.UIElement element = ultraGrid1.DisplayLayout.UIElement.LastElementEntered;
            UltraGridRow row = element.GetContext(typeof(UltraGridRow)) as UltraGridRow;

            if (null == row)
            {
                return;
            }

            if (null == InitialRowSelected)
            {
                InitialRowSelected = row;
            }


            if (ShiftKey) // if (row.ParentRow.Selected && ShiftKey)
            {
                //if (row.HasParent())
