Property Value

Examples

The following code example adds three Button controls to a worksheet. These buttons share a Click event handler that uses the Index property to display the index of the button that was clicked.

This example is for a document-level customization.

Private Sub DisplayIndex()
    Dim IndexButton1 As Microsoft.Office.Tools.Excel.Controls.Button = _
        Me.Controls.AddButton(Me.Range("B2", "C3"), "IndexButton1")
    IndexButton1.Text = "Click to view the index" 
    AddHandler IndexButton1.Click, AddressOf indexButton_Click

    Dim IndexButton2 As Microsoft.Office.Tools.Excel.Controls.Button = _
        Me.Controls.AddButton(Me.Range("B5", "C6"), "IndexButton2")
    IndexButton2.Text = "Click to view the index" 
    AddHandler IndexButton2.Click, AddressOf indexButton_Click

    Dim IndexButton3 As Microsoft.Office.Tools.Excel.Controls.Button = _
        Me.Controls.AddButton(Me.Range("B8", "C9"), "IndexButton3")
    IndexButton3.Text = "Click to view the index" 
    AddHandler IndexButton3.Click, AddressOf indexButton_Click
End Sub 

Private Sub IndexButton_Click(ByVal sender As Object, ByVal e As EventArgs)
    Dim ClickedButton As Microsoft.Office.Tools.Excel.Controls.Button = _
        CType(sender, Microsoft.Office.Tools.Excel.Controls.Button)

    MsgBox("The index is " & ClickedButton.Index.ToString())
End Sub

private void DisplayIndex()
{
    Microsoft.Office.Tools.Excel.Controls.Button indexButton1 =
            this.Controls.AddButton(this.Range["B2", "C3"],
            "indexButton1");
    indexButton1.Text = "Click to view the index";
    indexButton1.Click += new EventHandler(indexButton_Click);

    Microsoft.Office.Tools.Excel.Controls.Button indexButton2 =
            this.Controls.AddButton(this.Range["B5", "C6"],
            "indexButton2");
    indexButton2.Text = "Click to view the index";
    indexButton2.Click += new EventHandler(indexButton_Click);

    Microsoft.Office.Tools.Excel.Controls.Button indexButton3 =
            this.Controls.AddButton(this.Range["B8", "C9"],
            "indexButton3");
    indexButton3.Text = "Click to view the index";
    indexButton3.Click += new EventHandler(indexButton_Click);
}

void indexButton_Click(object sender, EventArgs e)
{
    Microsoft.Office.Tools.Excel.Controls.Button clickedButton =
        (Microsoft.Office.Tools.Excel.Controls.Button)sender;

    MessageBox.Show("The index is " +
        clickedButton.Index.ToString());
}
