This will give you the same effect as setting the CheckBox control to Null (the OptionButton appears dimmed).

The following example macro demonstrates setting an OptionButton to Null.

Setting up the Control

1. Close and save any open workbooks, and then open a new workbook.
2. If the Control Toolbox is not visible, point to Toolbars on the View menu, and then click Control Toolbox.
3. Click the OptionButton control on the Control Toolbox toolbar, and then draw an OptionButton on Sheet1.
4. Click the Exit Design Mode button on the Control Toolbox toolbar.

Sample Macro Code

1. On the Tools menu, point to Macro, and then click Visual Basic Editor.
2. On the Insert menu click Module.
3. Enter the following code in the module.

      Sub Set_Option()
   
      Dim Choice As Integer
      Dim MyPrompt As String
   
      MyPrompt =  "Type 1 for Selected, 2 for Not Selected and 3 for Grayed"
      Choice = InputBox(MyPrompt)
   
      Select Case Choice
   
         Case 1
            Sheet1.OptionButton1.Value = True
   
         Case 2
            Sheet1.OptionButton1.Value = False
   
         Case 3
            Sheet1.OptionButton1.Value = Null
   
         End Select
   
      End Sub
   						

Running the Macro

1. Activate Microsoft Excel (press ALT+F11).
2. Select any cell in Sheet1.
3. On the Tools menu, point to Macro, and then click Macros.
4. Select Set_Option and click Run.
5. Enter either 1, 2, or 3 in the InputBox when prompted, and click OK.

The OptionButton will be set to the state that matches the number you entered in the InputBox (1 = ON, 2 = OFF, 3 = Grayed).
