Hi all;
My problem seems to be quite simple, but it's not working the intuitive way.
I'm designing a Windows Forms Application, and there is a dialog that should NOT exit when the enter key is pressed, instead it has to validate data first, in case enter was pressed after changing the text of a ComboBox.
I've tried by telling it what to do on KeyPress event of the ComboBox if e is the Enter key:
Private Sub ComboBoxSizeChoose_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles ComboBoxSizeChoose.KeyPress
If e.KeyChar = Convert.ToChar(Keys.Enter) Then
Try
TamanhoDaNovaFonte = Single.Parse(ComboBoxSizeChoose.Text)
Catch ex As Exception
Dim Dialogo2 As New Dialog2
Dialog2.ShowDialog()
ComboBoxSizeChoose.Text = TamanhoDaNovaFonte
End Try
End If
End Sub
But no success so far. When the Enter key is pressed, even with the ComboBox on focus, the whole dialog is closed, returning to the previous form. The validation is NOT done at all, and it has to be done before exiting. In fact, I don't even want to exit on the form's enter KeyPress, the only purpose of the enter key on the whole dialog is to validate the ComboBox (but only when in focus, for the sake of an intuitive UI).
I've also tried appending the validation to the KeyPress event of the whole dialog's form, if the key is Enter. NO SUCCESS! It's like my code wasn't there at all.
What should I do?
