    Hi,

    In my code behind page i have

    private int propertyDescription = 1;

    which is defined just above the page load (under all the web controls)

    when someone checks a box i set propertyDescription = 2 in the event handler but the value isnt getting updated. Any ideas ?

    I know i should know how to do this !!

    Thanks

    Sounds like a state issue. Http is stateless so your site won't maintain values between the client and the server for you. You have to store them somewhere yourself. Put the value into ViewState or the Session to maintain it between the postbacks.

    Try 
    protected void Page_Load(object sender, EventArgs e)
{
   if(!IsPostBack)
   {
        ViewState["_propertyDescription"] = 1;
    }
}
// Your event handler goes here
protected void btnSubmit_Click(object sender, EventArgs e)
{
    ViewState["_propertyDescription"] = 2;
}

    Then to access the propertyDescription value 
    private void foo()
{
    // Assumes you want it as an Int32
    Int32 propDescription = Convert.ToInt32(ViewState["_propertyDescription]); 
}
