public Microsoft.Office.Tools.Excel.ControlSite AddControl (System.Windows.Forms.Control control, Microsoft.Office.Interop.Excel.Range range, string name);
abstract member AddControl : System.Windows.Forms.Control * Microsoft.Office.Interop.Excel.Range * string -> Microsoft.Office.Tools.Excel.ControlSite
Public Function AddControl (control As Control, range As Range, name As String) As ControlSite

Parameters

control
Control

The control to be added to the ControlCollection instance.

range
Range

A Range that provides the bounds for the control.

name
String

The name of the control that can be used to index the control in the ControlCollection instance.

Returns

ControlSite

An object that represents the control that contains the specified control on the worksheet.

Exceptions

ArgumentNullException

The control, name or range argument is null, or the name argument has zero length.

ControlNameAlreadyExistsException

A control with the same name is already in the ControlCollection instance.

InvalidRangeException

The range that was specified is not valid. Multi-area ranges cannot be used. The range should be on the same worksheet as the ControlCollection instance.

Examples

The following code example adds two custom user controls to the worksheet using the AddControl method. The first control is added to a range of cells. The second control is added to a specific location. The code changes the Top property of the first custom user control, which only moves the control relative to the ControlSite that contains the control on the worksheet. The code then sets the Top property of the ControlSite returned by the second user control to illustrate the correct way to set the Top property of the control.

private void ExcelRangeAddControl()
{

    UserControl1 customUserControl = new UserControl1();
    UserControl2 customUserControl2 = new UserControl2();

    Microsoft.Office.Tools.Excel.ControlSite dynamicControl =
        this.Controls.AddControl(customUserControl,
        0, 0, 150, 150, "dynamicControl");

    Microsoft.Office.Tools.Excel.ControlSite dynamicControl2 =
        this.Controls.AddControl(customUserControl2, 200, 0,
        150, 150, "dynamicControl2");

    customUserControl.BackColor = Color.Blue;
    customUserControl2.BackColor = Color.Green;

    customUserControl.Top = 100;
    dynamicControl2.Top = 100;
}

Private Sub ExcelRangeAddControl()

    Dim CustomUserControl As New UserControl1()
    Dim CustomUserControl2 As New UserControl2()

    Dim DynamicControl As Microsoft.Office.Tools.Excel.ListObject = Me.Controls.AddControl( _
        CustomUserControl, 0, 0, 150, 150, _
        "DynamicControl")

    Dim DynamicControl2 As Microsoft.Office.Tools.Excel. _
        ControlSite = Me.Controls.AddControl( _
        CustomUserControl2, 200, 0, 150, 150, _
        "DynamicControl2")

    CustomUserControl.BackColor = Color.Blue
    CustomUserControl2.BackColor = Color.Green

    CustomUserControl.Top = 100
    DynamicControl2.Top = 100

End Sub
