Question How to retain focus for listbox after setting index

[KAMPATEL1973]

Hi Guys,

I have some code as follows for a listbox that is in a windows form with an OK button:




What I am finding is that the item gets selected as I require, but the OK button on the form gets focus, ideally I would like the list box to retain focus even though I have selected an index for it to select.
Is there a way to do this?

            Dim source() As String = Split(xml, ",")
            Dim i As Integer
            For i = 0 To UBound(source)
                DialogBoxListBox.SelectList2.Items.Add(source(i))
            Next
            DialogBoxListBox.SelectList2.SelectedIndex = 0

Everything works ok, its just the focus part that's not working.

Any help appreciated...

Which form has focus when this code is executed? Which control?

There is only one form in the whole project and it has a list box on it with an OK button. I am looking at changing the tab index to see if this helps.

Thanks

If there's only one form then why does your code look like it's referring to a control on a different form?

That won't help because the listbox is not an input control, so the button will have initial focus no matter the tabindex order. You can select the listbox by using its Select method:

SelectList2.Select()

Using TabIndex really messed my forms up :-(. Its changed to 1 0.0 0.1 etc.

However using the method you have stated John. this has done what i wanted. Thanks
