Postback after selecting a value from a dropdown jquery

Question

After I select a value from a combobox in the page, it does not return on the server side.

<asp:DropDownList ID="dllTest" runat="server" AutoPostBack="true" OnSelectedIndexChanged="dllTest_SelectedIndexChanged">

I am making the dropdownlist to a combobox

$("#<%=dllTest.ClientID%>").combobox();

Also I want to trigger the ddlTest_SelectedIndexChange.

I tried doing this $('#dllTest').combobox(); and adding a property of the dropdown to ClientIDMode="Static" not working.

What I want is after I select a value from the combobox, the selectedindexchange will fire in code behind

You need to use select function of combo-box as as follows. Because when you use combo box it hide you drop-down list.

select: function (event, ui) {
                 ui.item.option.selected = true;
                self._trigger("selected", event, {
                     item: ui.item.option
                 }
                 );
                 __doPostBack('<%= dllTest.UniqueID %>', '');
             },
