Question

I’m developing a web application in visual studio 2010.

I’ve a list view and want the list box selectindexchange event to be fired when the user select a different item. but it is not working, as the page is not even refreshing. am i missing something?

Just to add some clarity to this question for future references:

1. I was using C#
2. Using a List Box from the visual studio toolbox.

<asp:ListBox ID="ListBox1" runat="server"
onselectedindexchanged="ListBox1_SelectedIndexChanged" AutoPostBack="True"></asp:ListBox>

Under the Properties of the ListBox1, the SelectedIndexChanged property is set to ListBox1_SelectedIndexChanged.

protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            ...some logic here...
        }
