    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

    Method to set

    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.

    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
