Hello Yong,

To answer your question, an alternative solution to prevent the Column CellAppearance BackColor from overriding the EmptyRowSettings CellAppearance BackColor is to use a DrawFilter.

The following code sample demonstrates how to use a DrawFilter for the EmptyRowSettings CellAppearance:

// Add this line of code to the Form Constructor to set
// the UltraGrid DrawFilter Property to the EmptyRowDrawFilter

ultraGrid1.DrawFilter = new EmptyRowDrawFilter ();

Add the following Class to the program:

public

class EmptyRowDrawFilter : IUIElementDrawFilter
{
     #region IUIElementDrawFilter Members
     bool IUIElementDrawFilter.DrawElement(DrawPhase drawPhase, 
                    ref UIElementDrawParams drawParams)
      {
            drawParams.AppearanceData.BackColor = Color.White;
            return false;
      }

      DrawPhase IUIElementDrawFilter.GetPhasesToFilter(ref UIElementDrawParams drawParams)
     {
            if (drawParams.Element is EmptyRowCellUIElement)
           {
                 return DrawPhase.BeforeDrawBackColor;
           }
           return DrawPhase.None;
     }
     #endregion
}

Please let me know if the above code provides the functionality you require or if you have any questions.

Thank you.
