Trying to use the following class to limit a textbox to text only:
However, it sees that its not text and e.Handled is false but its leaving the number in the textbox. How can i remove it?
Public Class LettersOnlyTextbox
Inherits TextBox
Public Class LettersOnlyTextbox
Inherits TextBox
Protected Overrides Sub onkeydown(e As System.Windows.Forms.KeyEventArgs)
Dim c = Convert.ToChar(e.KeyValue)
Select Case e.KeyCode
Case Keys.Back, Keys.Delete
e.Handled = False
Case Else
e.Handled = Not Char.IsLetter(c)
End Select
End Sub
End Class
I was able to solve it this way
Protected Overrides Sub onkeydown(e As System.Windows.Forms.KeyEventArgs)
Dim c = Convert.ToChar(e.KeyValue)
Select Case e.KeyCode
Case Keys.Back, Keys.Delete
e.Handled = False
Case Else
If Not Char.IsLetter(c) Then
e.SuppressKeyPress = True
End If
End Select
End Sub
