result of a modal form in vb.net - vb.net

Question

I create a form 'frmX' and i call it as a modal form :
res = frmX.ShowDialog()
This form has 3 buttons, Abort(3), Retry(4) and Ignore(5), but when the form opens, all the buttons on the first click return 2.
I don't know why this occurs--all of the buttons has their property DialogResult right.
*Private Sub btnIgnorar_Click(sender As Object, e As EventArgs) Handles btnIgnorar.Click
btnIgnorar.DialogResult = DialogResult.Ignore
End Sub
Private Sub btnAbortar_Click(sender As Object, e As EventArgs) Handles btnAbortar.Click
btnAbortar.DialogResult = DialogResult.Abort
End Sub
Private Sub btnReintentar_Click(sender As Object, e As EventArgs) Handles btnReintentar.Click
btnReintentar.DialogResult = DialogResult.Retry
End Sub*
Can someone help me?

Answer 1

Could do with seeing a bit more context, but the following should do what I think you want:
Private Sub btnIgnorar_Click(sender As Object, e As EventArgs) Handles btnIgnorar.Click
DialogResult = DialogResult.Ignore
Close
End Sub
This will close the dialog and return the associated result code to the caller. As to the original code, it seems a bit strange setting the values in the buttons click handlers?

Answer 2

The error comes from the fact that you set the DialogResult of the buttons. You must set the DialogResult of the form !
You actually have more than one option.
Option 1 : Set the Form.DialogResult
Private Sub btnIgnorar_Click(sender As Object, e As EventArgs) Handles btnIgnorar.Click
Me.DialogResult = DialogResult.Ignore
End Sub
Private Sub btnAbortar_Click(sender As Object, e As EventArgs) Handles btnAbortar.Click
Me.DialogResult = DialogResult.Abort
End Sub
Private Sub btnReintentar_Click(sender As Object, e As EventArgs) Handles btnReintentar.Click
Me.DialogResult = DialogResult.Retry
End Sub
Option 2 : Set the Button.DialogResult
Public Sub New()
InitializeComponents()
'Your init code here
'...
'By setting the buttons DialogResults, you don't even have to handle the click events
btnIgnorar.DialogResult = DialogResult.Ignore
btnAbortar.DialogResult = DialogResult.Abort
btnReintentar.DialogResult = DialogResult.Retry
End Sub
'However, if you need to do some stuff before closing the form, you can
Private Sub btnAbortar_Click(sender As Object, e As EventArgs) Handles btnAbortar.Click
'Do some stuff
'You don't need the following line, as it will be done implicitly
'Me.DialogResult = DialogResult.Abort
End Sub
