I need to get the current value of the WebDropDown.

I wrote the following code.

I get null in  the object combo

it seems to be that the problem is that I use master page this time

    </div> 

</asp:Content>

    IIRC You'll need to check in the selected item.

     function Button1_onclick() { 

                var combo = $find("comboCurrencies"); 
                var txt = combo.get_selectedItem().get_value(); 
            }


    Grtz.
