Public Function AddComboBox (controls As ControlCollection, range As Range, name As String) As ComboBoxParameters
- controls
- 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 Controls property (in an application-level project) or the Controls property (in a document-level project), this parameter is supplied automatically.
- name
- String
The name of the control that can be used to index the control in the ControlCollection instance.
Returns
The ComboBox control that was added to the ControlCollection instance.
Exceptions
The name or range argument is null, or the name argument has zero length.
A control with the same name is already in the ControlCollection instance.
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 a ComboBox control to cells A1 through B1, adds two items to the combo box, and then selects the first item. To use this example, run it from the Sheet1 class in a document-level project.
private void ExcelRangeAddComboBox()
{
Microsoft.Office.Tools.Excel.Controls.ComboBox
comboBox1 = this.Controls.AddComboBox(
this.Range["A1", "B1"], "comboBox1");
comboBox1.Items.Add("First Item");
comboBox1.Items.Add("Second Item");
comboBox1.SelectedIndex = 0;
}
Private Sub ExcelRangeAddComboBox()
Dim ComboBox1 As Microsoft.Office.Tools.Excel. _
Controls.ComboBox = Me.Controls.AddComboBox( _
Me.Range("A1", "B1"), "ComboBox1")
ComboBox1.Items.Add("First Item")
ComboBox1.Items.Add("Second Item")
ComboBox1.SelectedIndex = 0
End Sub
Remarks
The AddComboBox method enables you to add ComboBox objects to the end of the ControlCollection. To remove a ComboBox that was previously added programmatically, use the Remove method.
The control automatically resizes when the range is resized.
