SYMPTOMS

The event list of the TextBox control for Microsoft Windows forms does not display the following public event handlers that are documented in the Microsoft Developer Network (MSDN) library:

• Click
• ControlAdded
• ControlRemoved
• Disposal
• GetFocus
• HandleCreated
• HandleDestroyed
• Invalidated
• LostFocus
• MouseWheel
• Paint

RESOLUTION

To resolve this behavior, write event handlers manually for the events that do not appear in the event list.

To create a Click event handler:

1. Create a new Visual Basic .NET or Visual Basic 2005 Windows Application project.
2. Name the project SampleApplication, and then click OK.
3. Add a TextBox control to the form.

4. To add a Click event handler, add the following code to the existing code.

   Public Class Form1
       Inherits System.Windows.Forms.Form
   ...
       Private Sub TextBox1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.Click
           MsgBox("Clicked TextBox")
       End Sub
   ...
   End Class

   Note Events are not auto-populated. For more information about the control that gets parameter information for events, visit the MSDN Web site.

5. Run the application.
6. Click the TextBox control. A message box appears.

STATUS

Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

Steps to Reproduce the Behavior
