XL98: No Data Validation Property for UserForm TextBoxes

ID: Q184097

The information in this article applies to:

SYMPTOMS

When you add a TextBox control to a custom UserForm, you cannot use a property to automatically validate the data that is typed in the text box when you run a macro that displays the UserForm.

CAUSE

In Microsoft Excel 98 Macintosh Edition, you cannot use a property that allows you to validate the data. This behavior is different from earlier versions of Microsoft Excel. In earlier versions, you can set the InputType property for an Edit Box control that you place in a custom dialog box.

RESOLUTION

To validate the data that is typed in a text box on a custom UserForm, create an event-driven macro that verifies the data. For an example that shows you how to implement such a macro, please see the "More Information" section in this article.

The following example steps you through the process of creating a new UserForm with a TextBox control that allows you to type only numerical values in the text box. If you type nonnumeric data in the text box, a message box that prompts you to reenter the data or to cancel the procedure appears. To create the UserForm, follow these steps:

 1. Create a new workbook, point to Macro on the Tools menu, and click
    Visual Basic Editor to start the Visual Basic Editor.

 2. In the Visual Basic Editor, insert a new UserForm into your project.

 3. If the Toolbox is not visible, click Toolbox on the View menu.

 4. Click TextBox in the Toolbox, and then draw a text box on the UserForm.

 5. Double-click the text box.

 6. Type the following code in this Visual Basic module:

       Private Sub TextBox1_Change()

           Dim okstop As Boolean
           Dim yesno_continue As Boolean
           Dim mytext As String

           okstop = False

           Do
               mytext = TextBox1.Value
               If Not IsNumeric(mytext) And mytext <> "" Then
                   TextBox1.Value = ""    'Clears the TextBox

                   ' Displays a message box that informs you that you typed
                   ' something other than a number.
                   yesno_continue = MsgBox("Please type only numbers." & _
                       Chr(13) & "Continue?", vbYesNo)
               Else
                   okstop = True   'You typed a number in the TextBox.
               End If

           ' Continue with the loop if you click Yes.
           ' Stop the loop if they typed a number in the TextBox.
           Loop Until (yesno_continue = vbNo) Or (okstop = True)

       End Sub

 7. On the Insert menu, click Module.

    This step inserts a module sheet into the project.

 8. On this module sheet, type the following code:

       Sub Data_Validate()
           UserForm1.Show  'Displays the custom UserForm.
       End Sub

 9. Run the Data_Validate macro.

    Your custom UserForm appears. If you type a number in the text box,
    nothing happens. If you type a text string in the text box, the message
    box in the macro in step 6 appears and informs you that you did not
    type a number.

10. Click the Close button in the upper-right corner of the UserForm window
    to dismiss the UserForm.
