Has an item from the listbox been selected?

[gotham]

Does anyone know how to check if a selection has been made from a list Box?

[Lord_Rat]

I have a listbox named group:

Group.Items(Group.SelectedIndex).Value


As for handling the event, you need to have an event handler similar to:
Public Sub GroupSelected(ByVal sender As Object, ByVal e As EventArgs) Handles Group.SelectedIndexChanged

and the tag looks like:

<asp:DropDownList id="Group" runat="server" OnSelectedIndexChanged="GroupSelected" AutoPostBack="True"></asp:DropDownList>
