jQuery Grid Plugin - jqGrid

Hi,

I'm new to this plugin.I want to show 2 grids on same .aspx page. Both calling different web method to load the data. I can see the layout for both grids. But only one grid is loaded.Not the other one.Here is the code for ajax call.

 $(document).ready(function () {   
             $.extend($.jgrid.defaults,   
                  { datatype: 'json' },   
                  { ajaxGridOptions: { contentType: "application/json",   
                      success: function (data, textStatus) {   
                          if (textStatus == "success") {   
                              var thegrid = $("#Grid1")[0];
                              thegrid.addJSONData(data.d);
                             thegrid.grid.hDiv.loading = false;   
                              switch (thegrid.p.loadui) {   
                                  case "disable":   
                                      break;   
                                  case "enable":   
                                      $("#load_" + thegrid.p.id).hide();   
                                      break;   
                                  case "block":   
                                      $("#lui_" + thegrid.p.id).hide();   
                                      $("#load_" + thegrid.p.id).hide();   
                                      break;   
                              }
                                
                          }   
                      }   
                  }   
 
                 });    
               jQuery("#Grid1").jqGrid({   
                  url: 'AdvertiserRevenueActivityReport.aspx/GetDataTable',   
                  datatype: 'json',   
                  mtype: 'POST',

                  .........

              });

I'm doing the same for another grid too.

 $.extend($.jgrid.defaults,   
                  { datatype: 'json' },   
                  { ajaxGridOptions: { contentType: "application/json",   
                      success: function (data, textStatus) {   
                      if (textStatus == "success") {   
                              var summgrid = $("#gridSummary")[0];
                              summgrid.addJSONData(data.d);
                              summgrid.drid.hDiv.loading = false;  
                              switch (summgrid.p.loadui) {   
                                  case "disable":   
                                      break;   
                                  case "enable":   
                                      $("#load_" + summgrid.p.id).hide();   
                                      break;   
                                  case "block":   
                                      $("#lui_" + summgrid.p.id).hide();   
                                      $("#load_" + summgrid.p.id).hide();   
                                      break;   
                              }  
                          }   
                      }   
                  }   
              });
 
              jQuery("#gridSummary").jqGrid({   
                  url: 'AdvertiserRevenueActivityReport.aspx/GetSummaryDataTable',   
                  datatype: 'json',   
                  mtype: 'POST',

                  ........

             });

And I have two webmethod is .cs file.

[WebMethod]
   public static s_GridSummary GetSummaryDataTable(string _search, string nd, int rows, int page, string sidx, string sord, int totalrows)
   {}

[WebMethod]
   public static s_GridResult GetDataTable(string _search, string nd, int rows, int page, string sidx, string sord, int totalrows)
   {}

Following is also inside .cs file.

 public struct s_GridResult
  {
    public int page;
    public int total;
    public int record;
    public s_RowData[] rows;

  }
  public struct s_RowData
  {
    public int id;
    public string[] cell;
  }

  public struct s_GridSummary
  {
    public int page;
    public int total;
    public int record;
    public s_RowDataSummary[] rows;

  }
  public struct s_RowDataSummary
  {
    public int id;
    public string[] cell;
  }

I'm not sure the way I'm doing is right. Or what's a right way to do this?

Thanks,
