          .Name("_projectGrid")
          .Editable(editable =&gt; editable.Mode(GridEditMode.InCell))

          {
  
  
  
            columns.Bound(p =&gt; p.FixedPrice).Title(@Dev.Crm.Web.Resources.Shared.Project.Label_FixedPrice).EditorViewData(new { OnChangeCallback = "Product_List_updateProjectChanges" }).Width("15%").EditorTemplateName("Number");
  
  
          })
  
          .Pageable()
          .Sortable()

                      .DataSource(dataSource =&gt; dataSource
  
                          .Ajax()

                                    {
                                        model.Id(p =&gt; p.ProjectID);
                                        model.Field(p =&gt; p.ProjectID).Editable(false);
  
  
                                    })
          .Read(read =&gt; read.Url(@Url.Project_Operation_Read()).Data("Project_List_searchData"))// the name of the javascript function which will return the additional data.      
                          //.Destroy(destroy =&gt; destroy.Action("Delete", "Project"))
