Hi group,

I have got a custom textbox class.

How can I cancel/Block the TABKEY, to avoid a user can exit the the custom
textbox.

Please don't propose to set tabstop from the other controls to false because
can't do that for certain reasons.

I already tried this code INSIDE my custom textbox class:



Protected Overrides Sub OnKeyPress(ByVal e As
System.Windows.Forms.KeyPressEventArgs)

If e.KeyChar = Chr(System.Windows.Forms.Keys.Tab) Then

e.Handled = True

Else

e.Handled = False

MyBase.OnKeyPress(e)

End If

End Sub





Protected Overrides Sub OnKeyDown(ByVal e As
System.Windows.Forms.KeyEventArgs)



If e.KeyCode = System.Windows.Forms.Keys.Tab Then

e.Handled = True

Else

e.Handled = False

MyBase.OnKeyUp(e)

End If







End Sub



It does not work. How can I achieve my purpose?



Best regards,

Mobile boy

Is your form's KeyPreview set to true?
