Hello,

 

I have a tab stripe and the tab Content which is a grid bound to datatable gets loaded with Ajax call like this

      @(Html.Kendo().TabStrip()
.Name("myKendoTabs")
.Animation(animation =>
{
    animation.Enable(false);
})
.SelectedIndex(0)
    .Items(t =>
    {
        t.Add().Text("Objektliste").LoadContentFrom("GetObjectsforAdress", "AdressActivity", new { strAdressID = ViewBag.SelAdressID });
    })
        )

 

And the GetObjectsforAdress method in Controller Returns a partial view

return PartialView("DocumentList", ds.Tables[0]);

 

and the partialview is like this

            @(Html.Kendo().Grid(Model)
    .Name("Grid_ObjActivity")
                  .Scrollable()
     .HtmlAttributes(new { style = "height: 300px;" })
     .DataSource(dataSource1 => dataSource1
                    .Ajax()
                    .PageSize(100)
                    .Model(model1 =>
                    {
                        if (Model != null)
                        {
                            foreach (System.Data.DataColumn ocolumn in Model.Columns)
                            {
                                model.Field(ocolumn.ColumnName, ocolumn.DataType);
                            }
                        }
                    })
 .ServerOperation(false)
                     )
                      .Resizable(resize => resize.Columns(true))
    .Columns(columns =>
    {
        if (ViewBag.ObjListHeader != null)
        {
            for (int j = 0; j < ViewBag.ObjListHeader.GetLength(0); j++)
            {
              
                            columns.Bound(ViewBag.ObjListHeader[j, 0]).Title(ViewBag.ObjListHeader[j, 0]).Width(120);
                   
            }
        }
    })
    .Selectable(selectable => selectable
            .Mode(GridSelectionMode.Single))
.Filterable(filterable => filterable
                                  .Extra(false)
                                  .Operators(operators => operators
                                      .ForString(str => str.Clear()
                                          .StartsWith("Starts with")
                                          .IsEqualTo("Is equal to")
                                          .IsNotEqualTo("Is not equal to")
                                      ))
                                  )
                              .Groupable()
                              .Reorderable(r => r.Columns(true))
                    .Resizable(r => r.Columns(true))
                              )

 

The Problem is when the tab is selected then GetObjectsforAdress method is called twice. Loads once and again loads. Not sure why it is called twice.

Can you please suggest what am i doing wrong here.

 

Thanks

Looks like i had

$("#myKendoTabs").kendoTabStrip(); in

document.ready function. And that could be the culprit reinitializing Kendo tab. I remember adding this line as in one tab  have a Kendo Editor and that was read only if i do not call this in document ready.

 

Thnaks anyways
