Syntax

'Declaration
<ExtensionAttribute> _
Public Shared Function AddLinkLabel ( _
    controls As ControlCollection, _
    range As Range, _
    name As String _
) As LinkLabel

public static LinkLabel AddLinkLabel(

    Range range,
    string name
)

Parameters

• controls
  Type: Microsoft.Office.Tools.Excel.ControlCollection

  The collection to add the control to. Do not supply this parameter yourself. When you call this method on the collection returned by the Worksheet.Controls property (in an application-level project) or the WorksheetBase.Controls property (in a document-level project), this parameter is supplied automatically.

• range
  Type: Range

  A Range that provides the bounds for the control.

• name
  Type: System.String

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

Return Value

Type: Microsoft.Office.Tools.Excel.Controls.LinkLabel
The LinkLabel control that was added to the ControlCollection instance.

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 or range argument is nulla null reference (Nothing in Visual Basic), 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.

Remarks

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

The control automatically resizes when the range is resized.

Examples

The following code example adds a LinkLabel control to cell A1, and then changes the text to First Name. The code then changes the color of the link to blue and sets the LinkBehavior to HoverUnderline. To use this example, run it from the Sheet1 class in a document-level project.

Private Sub ExcelAddLinkLabel()

        Dim LinkLabel1 As Microsoft.Office.Tools.Excel. _
            Controls.LinkLabel = Me.Controls.AddLinkLabel( _
            0, 0, 75, 17.25, "LinkLabel1")
        LinkLabel1.Text = "First Name"
        LinkLabel1.LinkColor = Color.Blue
        LinkLabel1.LinkBehavior = LinkBehavior.HoverUnderline

    End Sub

private void ExcelAddLinkLabel()
{

    Microsoft.Office.Tools.Excel.Controls.LinkLabel
         linkLabel1 = this.Controls.AddLinkLabel(
         0, 0, 75, 17.25, "linkLabel1");
    linkLabel1.Text = "First Name";
    linkLabel1.LinkColor = Color.Blue;
    linkLabel1.LinkBehavior = LinkBehavior.HoverUnderline;
}
