Your listbox biding is correct but you should place it under Page Load event delegate and "Not Page.IsPostBack" condition to retain your listbox state.
<br />
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
if(!Page.IsPostBack)<br />
{<br />
query = "select CustId,FirstName+' '+LastName as Name from custdetails where BrokerId='" + Session["broker"] + "'";<br />
dt = obj.select(query);<br />
ListBox1.DataSource = dt;<br />
ListBox1.DataTextField = "Name";<br />
ListBox1.DataValueField = "CustId";<br />
ListBox1.DataBind();
}<br />
}<br />
<br />
protected void Button1_Click(object sender, EventArgs e)<br />
{<br />
Label2.Text = ListBox1.SelectedValue;<br />
}<br />
<br />

Thanks a lot....
But why did it not work before...

You have a typo error from your first post. See the bold font below.
query = "select CustId,FirstName+' '+LastName as Name from custdetails where BrokerId='" + Session["broker"] + "'";
dt = obj.select(query);
ListBox1.DataSource = dt;
ListBox1.DataTextField = "Name";
ListBox1.DataValueField = "CustId";
this.DataBind(); //"this" must be replaced by ListBox1.

You need to use a DNS to resolve the IPAddress.

This is why people look at the Certification with a suspicious eye these days.

microsot doesn't need money from a citizen of a developing country like me

It is not about the money alone Maite.
It is about the efforts too. You did not even want to make efforts to look in the internet for the available materials when it has loads of it available already.

It is for this reason that any company who hires people b/c they are certified, is plainly clueless.
