Question

i have a ListView sitting on a form in .NET.

Before the form is hidden the SelectedIncides are present and valid:

void buttonOK_click()
{
    Assert(listView.SelectedIndices.Count > 0);
    DialogResult = DialogResult.OK;
}

But after the modal form returns:

form1.ShowDialog();
Assert(form1.listView.SelectedIndices.Count > 0); 

This 2nd assertion fails.

How do read the SelectedIndices of a ListView once the form the listview is on is hidden (although not destroyed/disposed/freed)?

Answer 1

You could try having a public var on form1 which holds a List (or equivalent) of the selected indices? Have form1 set it on the form closing event. Once control is passed back to your original form you could just access that instead?
