Optional Parameters

For information on optional parameters, see Optional Parameters in Office Solutions.

The following code example sets cells A1 through A5 to five different name strings and then uses the AutoFilter method to filter for the name "Robert".

This example is for a document-level customization.

private void SetAutoFilter()
    this.Range["A1"].Value2 = "Kathleen";
    this.Range["A2"].Value2 = "Robert";
    this.Range["A3"].Value2 = "Paul";
    this.Range["A4"].Value2 = "Harry";
    this.Range["A5"].Value2 = "George";

    Microsoft.Office.Tools.Excel.NamedRange namedRange1 =
        this.Controls.AddNamedRange(this.Range["A1", "A5"],

    namedRange1.AutoFilter(1, "Robert",
        Excel.XlAutoFilterOperator.xlAnd, true);
