    Adding a Gradient to Header Cells
    In This Topic

    You can change the appearance of header cells by adding a color gradient. You can have a gradient from one color to another color.

    You can implement a gradient appearance by creating a custom class that inherits existing cell classes (a general cell, in this case) and change the display to a gradient. You can also use the GradientHeaderRenderer class.

    Header cells with color gradient

    Using a Shortcut

    Use the GradientHeaderRenderer class and the Renderer property for the column header row and row header column.


    This example sets a gradient for the headers and the sheet corner.

    FarPoint.Win.Spread.CellType.GradientHeaderRenderer gr = new FarPoint.Win.Spread.CellType.GradientHeaderRenderer(Color.Yellow,Color.Orange, Color.YellowGreen, Color.Bisque,Drawing2D.LinearGradientMode.ForwardDiagonal);
    fpSpread1.ActiveSheet.ColumnHeader.Rows[0].Renderer = gr;
    fpSpread1.ActiveSheet.RowHeader.Columns[0].Renderer = gr;
    fpSpread1.ActiveSheet.SheetCorner.DefaultStyle.Renderer = gr;
    Copy Code
    Dim gr As New FarPoint.Win.Spread.CellType.GradientHeaderRenderer(Color.Yellow, Color.Orange, Color.YellowGreen, Color.Bisque, Drawing2D.LinearGradientMode.ForwardDiagonal)
    fpSpread1.ActiveSheet.ColumnHeader.Rows(0).Renderer = gr
    fpSpread1.ActiveSheet.RowHeader.Columns(0).Renderer = gr
    fpSpread1.ActiveSheet.SheetCorner.DefaultStyle.Renderer = gr
