Load data into grid

[harlem98]

I'm having huge problems loading data into a grid. i've encountered a number of problems, which i´ve been solving through different approachs, and now i dont have any exception, but i still cant load the data into the grid.

The data is filtered according to "rdpInvestigador" external selectedValue, and should load in the grid accordingly.

I use a n-layer architecture and ASP ObjectDataSource to Bind DB.

I will put the main parts of the code, in order to be possible to understand and find the issue. I will also attach an image with the appearence of the system.

I believe the problem is on CS code, but it could also be on the BLL "GetList" method.

// HTML

<script type="text/javascript">
  function refreshGrid(arg) {
  var radManager = $find('<%=
  RadAjaxManager.GetCurrent(Page).ClientID %>');
  if (!arg) {
   radManager.ajaxRequest("Rebind");
  }
    else {
   radManager.ajaxRequest(arg);
            }
   }
 
function myUserControlClickHandler() {
$find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest("FromUserControl");                       }
 </script>
