public:
 property Microsoft::Office::Interop::Excel::AutoFilter ^ AutoFilter { Microsoft::Office::Interop::Excel::AutoFilter ^ get(); };

member this.AutoFilter : Microsoft.Office.Interop.Excel.AutoFilter

Public ReadOnly Property AutoFilter As AutoFilter

Property Value

AutoFilter

A AutoFilter that provides information about filtered lists on the worksheet if filtering is enabled; otherwise, null.

Examples

The following code example creates a filtered list of fruits in a Range, and then uses the AutoFilter property to display the filter criteria for the list. The example then prompts the user to turn off the filter by using the AutoFilterMode property, and finally uses the FilterMode property to display whether the worksheet has a filtered list.

This example is for a document-level customization.

private void ActivateAutoFilter()
{
    this.Range["A1"].Value2 = "Fruits";
    this.Range["A2"].Value2 = "Banana";
    this.Range["A3"].Value2 = "Apple";
    this.Range["A4"].Value2 = "Banana";
    this.Range["A5"].Value2 = "Orange";
    this.Range["A6"].Value2 = "Apple";
    this.Range["A7"].Value2 = "Orange";

    Microsoft.Office.Tools.Excel.NamedRange NamedRange1 =
        this.Controls.AddNamedRange(this.Range["A1", "A7"],
        "NamedRange1");

    NamedRange1.AutoFilter(1, "Apple",
       Excel.XlAutoFilterOperator.xlAnd, true);

    MessageBox.Show("The current criteria for the AutoFilter is: " +
        this.AutoFilter.Filters[1].Criteria1.ToString());

    if (this.AutoFilterMode)
    {
        if (DialogResult.Yes == MessageBox.Show("Would you like to " +
            "turn off the filter?", "Example", MessageBoxButtons.YesNo))
        {
            this.AutoFilterMode = false;
        }
    }

    if (this.FilterMode)
    {
        MessageBox.Show("The worksheet has a filtered list.");
    }
    else
    {
        MessageBox.Show("The worksheet does not have a filtered list");
    }
}

Private Sub ActivateAutoFilter()
    Me.Range("A1").Value2 = "Fruits"
    Me.Range("A2").Value2 = "Banana"
    Me.Range("A3").Value2 = "Apple"
    Me.Range("A4").Value2 = "Banana"
    Me.Range("A5").Value2 = "Orange"
    Me.Range("A6").Value2 = "Apple"
    Me.Range("A7").Value2 = "Orange"

    Dim NamedRange1 As Microsoft.Office.Tools.Excel.NamedRange = _
        Me.Controls.AddNamedRange(Me.Range("A1", "A7"), "NamedRange1")

    NamedRange1.AutoFilter(1, "Apple", Excel.XlAutoFilterOperator.xlAnd, _
        VisibleDropDown:=True)

    MsgBox("The current criteria for the AutoFilter is: " & _
        Me.AutoFilter.Filters(1).Criteria1.ToString())

    If Me.AutoFilterMode Then
        If DialogResult.Yes = MessageBox.Show("Would you like to " & _
            "turn off the filter?", "Example", MessageBoxButtons.YesNo) Then
            Me.AutoFilterMode = False
        End If
    End If

    If Me.FilterMode Then
        MsgBox("The worksheet has a filtered list.")
    Else
        MsgBox("The worksheet does not have a filtered list")
    End If
End Sub

Remarks

To programmatically enable filtering, use the AutoFilter method of the Range object or the AutoFilter method of a NamedRange object.
