Assembly:  Microsoft.Office.Tools.Excel.v4.0.Utilities (in Microsoft.Office.Tools.Excel.v4.0.Utilities.dll)

Syntax

'Declaration
<ExtensionAttribute> _
Public Shared Function AddTextBox ( _
    controls As ControlCollection, _
    range As Range, _
    name As String _
) As TextBox
public static TextBox AddTextBox(
    this ControlCollection controls,
    Range range,
    string name
)

Parameters

Return Value

Type: Microsoft.Office.Tools.Excel.Controls.TextBox
The TextBox 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 AddTextBox method enables you to add TextBox objects to the end of the ControlCollection. To remove a TextBox 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 TextBox control to cells A1 through B2, and then assigns text to the control. To use this example, run it from the Sheet1 class in a document-level project.

Private Sub ExcelRangeAddTextBox()
    Dim TextBox1 As Microsoft.Office.Tools.Excel. _
        Controls.TextBox = Me.Controls.AddTextBox( _
        Me.Range("A1", "B2"), "TextBox1")

    TextBox1.Text = "Sample text" 

End Sub
private void ExcelRangeAddTextBox()
{
    Microsoft.Office.Tools.Excel.Controls.TextBox
         textBox1 = this.Controls.AddTextBox(
         this.Range["A1", "B2"], "textBox1");
    textBox1.Text = "Sample text";
}
