I have this event handler for SelectedValueChanged on a ListBox:
private void SelectedValueChangedEvent(object sender, EventArgs e)
{
string sFilename = fileListBox.SelectedValue.ToString();
}
There's a NullReferenceException at runtime,
"System.NullReferenceException: Object reference not set to an instance
of an object". What's up? Evidently the value has changed as it reaches
the handler. To null? The listbox is not empty.
