JQGrid

Hi,

I am using JQGrid for showing results from database. Now I need to update rows by user. I have tried to use Inline Navigator. I have used the following code for making the grid.

 $("#MyGrid").jqGrid({
            url: service,
            datatype: "json",
            mtype: 'GET',
            colNames: ['Col1', 'Col2'],
            colModel: [
      { name: 'Col1', index: 'Col1', sortable: true, resizable: true, editable: true, sorttype: "text" },
      { name: 'Col2', index: 'Col2', align: 'left', sortable: true, resizable: true, width: 50, editable: true },
           
            pager: '#pagerLab',
            rowNum: 1000,
            rowList: [10, 30, 100, 1000],
            sortname: 'modified',
            viewrecords: true,
            gridview: true,
             loadonce: true,        
            editurl: '/Service.svc/UpdateGrid',
        });
          jQuery("#MyGrid").jqGrid('navGrid', "#pagerLab", { edit: true, add: false, del: false, search:false });
        jQuery("#MyGrid").jqGrid('inlineNav', "#pagerLab");

}

Now I am not sure how to write the server side code to save user's changes in database. I am using AJAX enabled web service.

Here is my web service code for showing the grid:

[OperationContract]
          [WebInvoke(Method = "GET", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]
          public JQGridViewTable MyGrid(string ID)
          {
              Reader reader = new Reader();

              return Reader.ReadDetails(ID);
          }

And my C# code in Reader class(in data model):

public JQGridViewTable ReadDetails(string ID)
      {
             JQGridViewTable table = new JQGridViewTable();
      // read data from database and store in table
          return table;
      }

I need help with:

1- Do I need to use Post instead of Get? Notice that I am displaying and editing the grid in one function.
2- Do I need to add anything else in Javascript? for example edit or restore functions? In documentations they have edit and restore functions in inline editing but not in Inline navigation.
3- In what format data is sent to web service for editing? For displaying, it is in JQGridView format.
4- I don't know how to implement UpdateGrid method in web service, because I don't know what exactly Inline Navigator functions are doing, what data it is sending to web service and what data it is expecting from server.

I have searched the whole web, but everyone is using it in a different way.
I would appreciate any help.
