Examples

The following code example adds two custom user controls to the document using the AddControl method. The first control is added to a Range. 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 document. 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 Sub WordRangeAddControl()
    Me.Paragraphs(1).Range.InsertParagraphBefore()
    Dim CustomUserControl As New UserControl1()
    Dim CustomUserControl2 As New UserControl2()

    Dim DynamicControl As Microsoft.Office.Tools.Word.ControlSite = _
        Me.Controls.AddControl(CustomUserControl, _
        Me.Paragraphs(1).Range, 150, 150, "DynamicControl")

    Dim DynamicControl2 As Microsoft.Office.Tools.Word.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

private void WordRangeAddControl()
{
    this.Paragraphs[1].Range.InsertParagraphBefore();
    UserControl1 customUserControl = new UserControl1();
    UserControl2 customUserControl2 = new UserControl2();

    Microsoft.Office.Tools.Word.ControlSite dynamicControl =
        this.Controls.AddControl(customUserControl, 
        this.Paragraphs[1].Range, 150, 150, "dynamicControl");

    Microsoft.Office.Tools.Word.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;
}
