Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type ControlCollection. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Exceptions

Exception	Condition
ArgumentNullException	The name argument is nulla null reference (Nothing in Visual Basic) or has zero length.
ControlNameAlreadyExistsException	A control with the same name is already in the ControlCollection instance.

Remarks

The AddCheckBox method enables you to add CheckBox objects to the end of the ControlCollection. To remove a CheckBox control that was previously added programmatically, use the Remove method.

Examples

The following code example adds a CheckBox control to the top of the worksheet, and then adds text to the check box. To use this example, run it from the Sheet1 class in a document-level project.

Private Sub ExcelAddCheckBox()

        Dim CheckBox1 As Microsoft.Office.Tools.Excel. _
            Controls.CheckBox = Me.Controls.AddCheckBox( _
            0, 0, 78, 18, "CheckBox1")
        CheckBox1.Text = "Underline" 

    End Sub

private void ExcelAddCheckBox()
{
    Microsoft.Office.Tools.Excel.Controls.CheckBox checkBox1 =
        this.Controls.AddCheckBox(0, 0, 78, 18, "checkBox1");
    checkBox1.Text = "Underline";
}
