  You may be wraped in other controls...if you placed in another control just use FindControl Attribute.

  for ex:

  DropDownList ddl2=(DropDownList )panel1.FindControl("Your DDl Control ID");

  Here we Placing ddl2 in Panel

  hi

   function GetItemName() {
              var pageUrl = '<%=ResolveUrl("/Forms/MaterialRequest.aspx")%>';
              var projectStatus = $("#<%=ddlCategory.ClientID%>").val();
              debugger;
              $.ajax({
                  type: "POST",
                  url: pageUrl + '/getItemName',
                  data: '{ItemId:' + projectStatus + '}',
                  contentType: "application/json; charset=utf-8",
                  dataType: "json",
                  success: function OnlocationsPopulated(dvList) {
                      $("#<%=ddlItemName.ClientID%>").empty();
                      if (dvList.d.length > 0) {
                          $("#<%=ddlItemName.ClientID%>").removeAttr("disabled");
                          for (i = 0; dvList.d.length > i; i++) {
                              $("#<%=ddlItemName.ClientID%>").append("<option value=" + dvList.d[i].Value + ">" + dvList.d[i].Text + " </option>");
                          }
                      }
                      else {
                          $("#<%=ddlItemName.ClientID%>").empty().append('<option selected="selected" value="0">--Select--<option>');
                      }
                  }
              });
          }

  
  

  <asp:DropDownList ID="ddlItemName" runat="server" CssClass="bigdropdownList">

              dvList = BLL.Sales.clsMaterialRequest.GetItemDetails1(ItemId);

  try to give the AutopostBack="True" for the second dropdown. What it does is, the moment you select some value in the DropDown, the page gets refreshed and you will get the value expected where ever you want.

  But even if you do not provide that, still you should be getting it. But try the above and see if that does not harm or effect your process.

  Thanks
