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

Syntax

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

public static CheckedListBox AddCheckedListBox(
    this ControlCollection controls,
    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: Microsoft.Office.Interop.Excel.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.CheckedListBox
The CheckedListBox 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 AddCheckedListBox method enables you to add CheckedListBox objects to the end of the ControlCollection. To remove a CheckedListBox 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 CheckedListBox control to cells A1 through B5, adds two items to the checked list box, and then selects the First Item check box. To use this example, run it from the Sheet1 class in a document-level project.

    Private Sub ExcelRangeAddCheckedListBox()

        Dim CheckedListBox1 As Microsoft.Office.Tools. _
            Excel.Controls.CheckedListBox = Me.Controls. _
            AddCheckedListBox(Me.Range("A1", "B5"), _
            "CheckedListBox1")
        CheckedListBox1.Items.Add("First Item")
        CheckedListBox1.Items.Add("Second Item")
        CheckedListBox1.SetItemChecked(0, True)

    End Sub

private void ExcelRangeAddCheckedListBox()
{

    Microsoft.Office.Tools.Excel.Controls.CheckedListBox
        checkedListBox1 = this.Controls.AddCheckedListBox(
        this.Range["A1", "B5"], "checkedListBox1");
    checkedListBox1.Items.Add("First Item");
    checkedListBox1.Items.Add("Second Item");
    checkedListBox1.SetItemChecked(0, true);
}
