I know has that and gives the text but I need a values... so if I use like that

protected void RadComboBox1_ItemDataBound(object sender, RadComboBoxItemEventArgs e)
        {
            //set the Text and Value property of every item
            //here you can set any other properties like Enabled, ToolTip, Visible, etc.
            e.Item.Text = ((DataRowView)e.Item.DataItem)["ContactName"].ToString() ;
            e.Item.Value = ((DataRowView)e.Item.DataItem)["CustomerID"].ToString();
        }

it gives me values but I dont need on the Itemdatabound event.. because I am after when user selects have multiple values already done selecting.... which event I should try..

no event needed... get them on page_load

(why people use RadComboBox1 as id of the control? you should say rcbContacts or something like that, best practices...)

foreach (RadComboBoxItem item in RadComboBox1) {
  if (item.Selected) doSomething(item);
}

...

void doSomething(RadComboBoxItem item){
  Response.Write("<li>[" + item.Index + "] " + item.Value + " : " + item.Text);
}

thank you for your reply.  instead of line 8, since all I need item.value , and I am interested in getting multiple values, how can I combine values in under one statement.. For ex. my combobox item's value comes back as 1 , than 4, then 8   how can I combine those as totalString = {1,4,8} because I need to pass this value to stored proc. as a varchar string than probably use a split function to separete to values to 1
    4
    8  again  for each customer ID...

here it is:

string v ="";
foreach (RadComboBoxItem item in RadComboBox1.items) {
  v = (v=="")?item.Value.ToString():","+item.Value.ToString();
}

or for c# dummies :)

string v ="";
foreach (RadComboBoxItem item in RadComboBox1.items) {
  if (v == "") v = item.Value.ToString(); else v = v + "," + item.Value.ToString();
}

one fix

v = ((v == "") ? "" : ",") + item.Value.ToString();
-->
v = v + ((v == "") ? "" : ",") + item.Value.ToString();
