Help with controlling characters entered in a combo box of a Windows application.

hi ...Can you clarify a little bit more.In ComboBoxes we have a list of Values and we choose one of them...you need to filter these choises while typing only numbers 0 -9 and symbos "/" and "-" ?

Yes that is correct, forgot to mention letters A-Z are also allowed.

take a look at this
https://www.experts-exchange.com/questions/20866840/Allow-only-letter-number-or-backspace-in-textbox-vb-net.html

    Private Sub ComboBox1_KeyPress(sender As System.Object, e As System.Windows.Forms.KeyPressEventArgs) Handles ComboBox1.KeyPress

        e.Handled = Not (Char.IsDigit(e.KeyChar) Or e.KeyChar = "." Or Char.IsLetter(e.KeyChar) Or e.KeyChar = "-")
    End Sub

Select allOpen in new window

Thanks for the code, need to leave office for about two hours, will get back to you later.

Note that the above code does not restrict the Left Right Directional Keys..
If you want to Restrict these Keys Also Use The Key Down Event like:

If e.KeyCode = Keys.Left Then
            e.SuppressKeyPress = True
        End If

Select allOpen in new window

Hi,

The code works but I am unable to remove data, back space does not work. Also when I include the second part of your in the key press event. I receive the following error:
keycode is not a member of system.Windows.Forms.KeyPressEventArgs, Í receive the same error message for SupressKeyPress.

Thanks,

V.

It works!

Thank You.

Victor
