Changing combobox value back to original on Cancel 1

[ookete]

This is probably a simple solution. I have a combobox that holds a list of products. Under certain conditions a change of product can effect the form, and I prompt the user for confirmation:

Private Sub cboProduct_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboProduct.SelectedIndexChanged

    Dim changeConfirm As DialogResult
    changeConfirm = MessageBox.Show("Are you sure?",, _
    MessageBoxButtons.YesNo)

    If changeConfirm = DialogResult.Yes Then
        ' run code
    End If

End Sub

However, when they hit No even though the code did not run, the comboox still holds the new value.

How do I actually prevent the combobox value from changing? Perhaps there is a different event I should use, or is there a PreviousValue method, or something like that?

Thanks a bunch.

No previous value Im afraid, though you might be able to use your underlying datasource to put the value back

Alternatively hold the value in a variable/property on the Enter Event of the combo, and put this value back if No is selected

...if it works dont mess with it

you could capture the value in the Enter event in a class level variable, then apply that value after the yes/no box.

You wanna cracker?

So I made the change as suggested and it works. The only problem is now the SelectedIndexChanged event is recursive... it is firing again when I change the value back to the old value, so I get the messagebox twice. I probably need to use a boolean to flag whether the change is an initial change or a reset.

 

[ThatRickGuy]

Yup, the boolean flag should take care of it.
