New Entry / Grouping behavior when using a Pop-up Editor

[Richard]

I have a group-able Kendo grid with a pop-up editor. When the user clicks "New Entry" a new row is created in a new grouping even if the a group already exists for that value. Additionally, if the user clicks "Cancel" the incomplete row and its group is retained. If the user clicks "New Entry" again, the old incomplete entry is removed, but the group is retained.

How do I tell the Kendo Grid to not create a new row until the user has clicked OK for the new entry (and the entry has passed validation)? Is it possible to have this new row correctly placed in the appropriate grouping?

Thanks!

Hello Richard,

Creating a new group when adding new item is expected, unless there is a defaultValue for the column which the Grid is grouped by. Here I tried to reproduce the issue, but everything works as expected - both the new row and the new group are removed on Cancel. Could you please check the example and let me know if I am doing something differently? 
I am afraid that adding the new row only after pressing the OK button is currently not supported out of the box.

I know this is old, but I am having this same issue now as well.  I am grouping by a foreign key, and even tried adding a default value.  However, it still creates a new group (the new group is using the default value, which is an existing group, also odd...) and when I click cancel on the pop up editor, the new group and new row persist.  Any help or insight would be greatly appreciated!!  I was asked to add this property/foreign key specifically for grouping, so I need to get this right.

Here is my model:

public class RV_ReportViewModel
    {
        [ScaffoldColumn(false)]
        public int ReportId { get; set; }
        [DisplayName("Report Name")]
        public string ReportName { get; set; }
        [DisplayName("Report Path")]
        public string ReportPath { get; set; }
        [UIHint("GridForeignKey")]
        public int CategoryId { get; set; }
        public List<RV_ReportGroupsViewModel> Groups { get; set; }
    }

Here is the code for my grid. 

@(Html.Kendo().Grid<RV_ReportViewModel>()
                  .Name("gridReports")
                  .Columns(columns =>
                  {
                      columns.Bound(r => r.ReportName).Groupable(false);
                      columns.Bound(r => r.ReportPath).Groupable(false);
                      columns.ForeignKey(r => r.CategoryId,(System.Collections.IEnumerable)ViewData["categories"],"CategoryId","Name");
                      columns.Command(command =>
                      {
                          command.Edit();
                          command.Destroy();
                      }).Width(250);
                  })
                  .ClientDetailTemplateId("template")
                  .ToolBar(toolbar => toolbar.Create())
                  .Editable(editable => editable.Mode(GridEditMode.PopUp))
                  .Pageable()
                  .Sortable()
                  .Filterable()
                  .Groupable()
                  .DataSource(dataSource => dataSource
                      .Ajax()
                      .PageSize(10)
                      .Model(model =>
                      {
                          model.Id(s => s.ReportId);
                          model.Field(s => s.CategoryId).DefaultValue(1);
                      })
                      .Create(update => update.Action("Report_Create", "ReportViewer"))
                      .Read(read => read.Action("Report_Read", "ReportViewer"))
                      .Update(update => update.Action("Report_Update", "ReportViewer"))
                      .Destroy(update => update.Action("Report_Destroy", "ReportViewer"))))

Hi Cristina,

I am sending a sample runnable application which we can use as a reference point. Please modify the BatchSearch View in the attached sample ( run with /Home/BatchSearch ) to replicate the described scenario and send it back to us for further investigation.

Hi Eyup,

 I know this is just under 12 months old but I am having the exact same issue as above. I have added the DefaultValue but experience the same behavior. Did you guy's come up with a resolution?

 I can provide more details if required.

Thanks

Tom

Hello Tom,

At the moment there is no workaround that to be universal and to work in all configurations of the grid.

The new item have only top and bottom position to be placed at. And this is the reason it creates a group to be visible in. It is the desired approach and we do not plan to change it.
