    How to append DropDownList value to button's PostBackUrl?

    Hi,

    I have a button whose PostBackUrl should include a value from a dropdownlist
    on the same page. Should I do that in the button's on click event? What
    I'd like to end up with is a post back url that looks like the following:
    PostBackUrl=som epage.aspx?para m=<valuewhere <valuecomes from the
    currently selected item in the list.

    Thanks,
    Rob

      Hi,

      this does not reply 100% exactly what you asked for but in my post

      ASP.NET: trigger cross-page postback on ListBox selection change
      http://aspadvice.com/blogs/joteke/archive/2007/11/11/ASP.NET_3A00_-trigger-cross_2D00_page-postback-on-ListBox-selection-change.aspx


      I demonstrate how to use PostBackUrl type of stuff (=cross-page postback)
      so that the value is accessible via PreviousPage

          Forgot to say, it should also work for DropDownList just as well as for
          ListBox.
