Examples

The following code example adds a Button control to a worksheet and uses the Border property to color the border of the cell green. The Click event handler of the button uses the Visible property to hide the button, and then prompts the user to choose to either unhide the button, or allow it to remain hidden.

This example is for a document-level customization.

Private Sub AlterControlAppearance()
    Dim HideButton As Microsoft.Office.Tools.Excel.Controls.Button = _
        Me.Controls.AddButton(Me.Range("B2", "C3"), "HideButton")

    HideButton.Text = "Click to hide"
    HideButton.Border.Color = ColorTranslator.ToOle(Color.Green)
    AddHandler HideButton.Click, AddressOf hideButton_Click
End Sub 

Private Sub HideButton_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)
    ClickedButton.Visible = False 

    ' Allow the user to make the button visible. 
    If DialogResult.Yes = MessageBox.Show( _
        "This sheet contains a hidden control." & _
        " Make it visible?", "Example", MessageBoxButtons.YesNo) Then
        ClickedButton.Visible = True 
    End If 
End Sub

private void AlterControlAppearance()
{
    Microsoft.Office.Tools.Excel.Controls.Button hideButton =
        this.Controls.AddButton(this.Range["B2", "C3"],
        "hideButton");

    hideButton.Text = "Click to hide";
    hideButton.Border.Color = ColorTranslator.ToOle(Color.Green);
    hideButton.Click += new EventHandler(hideButton_Click);
}

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

    // Allow the user to make the button visible. 
    if (DialogResult.Yes ==
        MessageBox.Show("This sheet contains a hidden control." +
        " Make it visible?", "Example", MessageBoxButtons.YesNo))
    {
        clickedButton.Visible = true;
    }
}
