                              <tr>
                                  <td align="right">
                                      <asp:Label ID="UserNameLabel" runat="server" AssociatedControlID="UserName">User Name:</asp:Label>
                                  </td>
                                  <td>&nbsp;
                                      **<asp:TextBox ID="UserName" runat="server" Width="150px"></asp:TextBox>**
                                      <asp:RequiredFieldValidator ID="UserNameRequired" runat="server" 
                                          ControlToValidate="UserName" ErrorMessage="User Name is required." 
                                          ToolTip="User Name is required." ValidationGroup="CreateUserWizard1">*</asp:RequiredFieldValidator>
                                  </td>

I am using this code to find the control

Protected Sub CreateUserWizard1_CreatedUser(ByVal sender As Object, ByVal e As System.EventArgs)
    Dim UserNameTextBox As TextBox = DirectCast(CreateUserWizardStep1.ContentTemplateContainer.FindControl("UserName"), TextBox)
    Roles.AddUserToRole(UserNameTextBox.Text, "User")

End Sub

but it gives me an error

“Error 12 Name ‘CreateUserWizardStep1’ is not declared.”

You’ll have to use FindControl() on LoginView to reference CreateUserWizardStep1 first.

Dim CreateUserWizardStep1 As CreateUserWizard = 
    DirectCast(LoginView4.FindControl("CreateUserWizard1"), CreateUserWizard)

and then you can do

If CreateUserWizardStep1 IsNot Nothing 

     Dim UserNameTextBox As TextBox = DirectCast(CreateUserWizardStep1.ContentTemplateContainer.FindControl("UserName"), TextBox)
        Roles.AddUserToRole(UserNameTextBox.Text, "User")
End If
