    I am having an aspx file where a value is saved in a variable after user inputs data. (i.e. customerID which is auto-generated from database is saved to an object  I defined).
    I am having one radComboBox which I set autoPostBack = true because I want other radComboBox's datasource to fulfill accordingly to the first one, but when I choose a value from the first combo the whole page refreshes because of the autoPostBack=true and the variable of the customer is set to null and doesn't keep its value.
    Is there a good way to bypass this problem without using session parameters ?

    It should be mentioned,my aspx file is having radMultiPage with 3 radPageViews.
    The 1st tab is where i get the new information, which I put in the 2nd tab, and my 2 comboboxes are on the 2nd tab.

    Thank you,

    Hi Tal,

    The value of the CustomerID object will be lost after postback if you don't recreate it or keep the value somewhere.  I think using the Session State is a good option. However there are multiple other options which you can use. For example store the CustomerID's value in a hidden field. The complete list is here.
