    Please find attached a snapshot of Form having 2 spreads. Visual Style is OFF for first spread and ON for the second one. Observe that for a comboboxcelltype if the cell is locked it appears as dithered in spread with visual style OFF and enabled with visual styles ON. The expected behavior is it should appear dithered. Any work around to fix this?

    <span style="font-family:Tahoma, Arial, Helvetica;font-size:12px;">I am using Spread Version 5.0.3511.2008</span>


    Here is the code:

     private void Form1_Load(object sender, EventArgs e)


                this.fpSpread1.ActiveSheet.Cells[0, 0].CellType = new FarPoint.Win.Spread.CellType.ComboBoxCellType();

                this.fpSpread1.ActiveSheet.Cells[0, 0].Locked = true;

                this.fpSpread2.ActiveSheet.Cells[0, 0].CellType = new FarPoint.Win.Spread.CellType.ComboBoxCellType();

                this.fpSpread2.ActiveSheet.Cells[0, 0].Locked = true;


     <span style="font-size:10pt;"> </span>

    This is the correct behavior wherein when VisualStyles is Off, it will render as dithered and if VisualStyle is On then it will render as enabled but you wont be able to click them as the cells are locked.

    Same behavior is observed with latest builds as well. And this is then intended behavior.

    Screenshots of the Spread with latest build is attached.
