I have a ListBox that when in focus, and when I have an item selected returns a valid SelectedIndex. If I have a valid SelectedIndex and I click on a TextBox on the same Forum, the SelectedIndex now becomes -1. However I want it to keep its SelectedIndex from changing. How would I go about doing this?
ListBox will keep it’s SelectedIndex regardless of focus.
I tested it on a blank project with one ListBox, one TextBox and one Label used to display the ListBox’s SelectedIndex. Under both the ListBox’s SelectedIndexChanged and the TextBox’s TextChanged events I updated the Label with the ListBox’s SelectedIndex
There must be something else going on to cause the Selected Index to change to -1.
