Grid Hierarchy - Child table dosen't show

[Jacob Saugmann]

Hi

Ive created at Hierarchy grid and the grid shows just fine in my .aspx page


But when i press the row to se the child table i get this:

When i debug my code i can see that the ActionResult ChildGrid does return a result


I've hidden the row where the id is for joining but it is passed to the code behind
What am i doing wrong?

My aspx:
   @{ Html.Syncfusion().Grid<DataRow>("GridSrc").Datasource(Model)
               .Caption("Hændelser")
               .AutoFormat(Skins.Metro)
               .AllowResizing(true)
               .AllowAutoWrap(true)
               .ChildGrid(child => child.ChildGridTemplate(Html.Syncfusion().Grid<DataRow>("ChildGrid_${JoinId}").Caption("Overblik over hændelser").Mappers(map => map.Action("ChildGrid", new { joinid = "${JoinId}" })).ToChildGridTemplate())).ClientSideEvents(events => { events.OnLoad("hideGridColumn"); }).Render();
        }

My codebehind:
        [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult ChildGrid(PagingParams args, string joinid)
        {
            DataTable table = new DataTable("Hændelser");

            using (SqlConnection sqlCon = new SqlConnection(_sqlConString))
            {
                try
                {
                    string sqlCmdQuery = @"SELECT
                                                Navn
                                                Maaned ,
                                                Aar ,
                                                Start_Dato ,
                                                Slut_Dato ,
                                                Type ,
                                                Varighed ,
                                                [Aktiv?]
                                        FROM Statistik.VW_OverblikAlleHaendelser AS VOAH
                                        WHERE VOAH.JoinId = '" + joinid +
                                         "' ORDER BY Start_Dato";
                   
                    SqlCommand sqlCmd;

                    sqlCmd = new SqlCommand(sqlCmdQuery);
                   
                    sqlCmd.Connection = sqlCon;

                    sqlCon.Open();

                    SqlDataAdapter sqlDataAdapter = new SqlDataAdapter(sqlCmd);
                    sqlDataAdapter.Fill(table);

                }
                catch (Exception exception)
                {

                }
                finally
                {
                    if (sqlCon.State == ConnectionState.Open)
                        sqlCon.Close();
                    sqlCon.Dispose();
                }
            }

            IEnumerable data = table.AsEnumerable().ToList();
            return data.GridActions<DataRow>();

        }

Hi Jacob,

 

Thanks for your patience.

 

We suggest you to set datasource for child grid initially to avoid your issue. Please refer the below code snippets.

 

[Index.cshtml]

  .ChildGrid(child =>
                        {
                            child.ChildGridTemplate(Html.Syncfusion().Grid<System.Data.DataRow>("ChildGrid_${OrderID}")
                            .Datasource((IEnumerable<System.Data.DataRow>)ViewData["data"])
                            .Caption("OrderDetails Grid")
                            .AutoFormat(Skins.Marble)                       
                            .EnablePaging()
                            .Mappers(map =>
                            {
                                map.Action("ChildGrid", new { OrderID = "${OrderID}" });
                            })
                            .ToChildGridTemplate());
                        })            

 

[HomeController.cs]

 public ActionResult Index()
        {
            ViewData["data"] = GetTable1(GetTable().Rows[0]["OrderID"].ToString()).AsEnumerable();
            return View(GetTable());
        }

 

For your convenience, we have prepared a simple sample to demonstrate this and the same can be downloaded from the below link.
