Question

I am trying to programmatically check a checkbox of a ListView (using VB & .NET 4).

The ListView lvVorschlag has been created in the designer, along with three elements. I then do the following:

Dim lviOptimal As New ListViewItem("Optimal")
lviOptimal.SubItems.Add(...) 'several SubItems are added
lvVorschlag.Items.Add(lviOptimal)
lvVorschlag.Items(0).Selected = True

All the SubItems are correctly added and the line lvVorschlag.Items(0).Selected = True does not give me an error. But nothing is checked. Any idea why?

Note: I also tried with lvVorschlag.Items("Optimal").Selected = True but it gives me an error saying that this object is Nothing. Too bad, referring by name would have been easier.

You should use the Checked property to check the item(s) you’d like:

lvVorschlag.Items(0).Checked = True
