    We have a drop down that is used to filter items in a gridview. The ddl is set to autopostback and the selected value is used as a selection parameter in the SQL data source. However, when it posts back, the item selected in the ddl now appears in the list as it normally would, and again at the bottom of the list items in the ddl.

     The ddl is databound to another SQL data source, which pulls unique names from the table.

     Any ideas?

    Are you adding the selected value back onto the list in the postback code?  That would do it. 

    If this answered your question, be sure to mark it as the answer. That way, everybody after you will know it's the answer also!

    If you are reloading the DropDown on postback, don't forget to clear the DD before re-adding the selected value.

                      dd_box.Items.Clear
