    Determining Which Header Row Displays the Indicators
    In This Topic

    If you have multiple column header rows then you can specify which row displays the filter indicators. By default they appear in the bottom column header row. You can specify which row displays the indicator by setting the AutoFilterIndex property of the ColumnHeader class.

    Using Code

    Set the ColumnHeader class AutoFilterIndex property to the row index to display the indicator. The row index is zero based, so the first row is 0.

    Example

    The following example sets the indicator to appear in the next to the bottom column header row.

    C#
    Copy Code
    fpSpread1.ActiveSheet.Columns[1].AllowAutoFilter = true;
    fpSpread1.ActiveSheet.ColumnHeaderRowCount = 3;
    fpSpread1.ActiveSheet.ColumnHeader.AutoFilterIndex = 1;
    VB
    Copy Code
    fpSpread1.ActiveSheet.Columns(1).AllowAutoFilter = True
    fpSpread1.ActiveSheet.ColumnHeaderRowCount = 3
    fpSpread1.ActiveSheet.ColumnHeader.AutoFilterIndex = 1
