DropdownList selectvalue does not seem to change

I have a dropdown list which is populated on page_load using a linq query. If I change the value in the dropdown then click a button to run an update query on the record, the original value is still there, if I step through in debug mode I can see the selected value is not changing at all

Here is how Im binding the data to dropdown

dlBookingRef.DataSource = d.BookingRef();
dlBookingRef.DataMember = "booking";
dlBookingRef.DataBind();

and here is the line in the function which gets the data from the form

item.booking_ref = dlBookingRef.SelectedValue;

Any idea why it's retaining its original value?

thanks

Put the binding code in if(!IsPostBack), it looks like that in button event as page load gets called due to that your dropdown list gets reset, so bind the dropdown only when page is not posted back:

protected void Page_Load(object sender, EventArgs e)
{    
    if(!Page.IsPostBack)
    {
    dlBookingRef.DataSource = d.BookingRef();
    dlBookingRef.DataMember = "booking";
    dlBookingRef.DataBind();
    }
}
