Grouping with column template not working

[Steve]

Hi,

    I read many thread talking about grouping not working with row template, but didn't find my problem with grouping and column template.

I have a simple grid (simplified version) here:

groupable: true,
  filterable: { extra: false },
  toolbar: ["create"],
  columns: [
                    { command: ["edit", "destroy"], title: " ", width: "200px" },
                    {
                        field: "Number",
                        title: "Numéro",
                        width: 140
                    },

                    {
                        field: "Parent",
                        title: "Parent",
                        template: "#= Parent == null ? '' : Parent.Number #",
                        editor: projectDropDownEditor,
                        filterable: {
                            extra: false,
                            field: "Parent.Number"
                        }
                    }
  ],

 

Because my parent column is a column template based on an object with Number and Id, grouping is not working.  Do you have any idea how to fix it?

 

Thank you for your help

Hello Steve,

Could you try the implementation, demonstrated in the forum thread below?

In case this does not help, please provide a runnable example of your scenario for further investigation.

Hi,

   I cannot use the example you provide, because it is a row template and not a column template grouping.  I did a little sample using Kendo UI Dojo.

Hello Steve,

Please excuse me for the misunderstanding.

In regard of the observed behavior I am afraid that it is not supported scenario. 

In order Grid to be able to group by "actors", it should know by which field exactly should group by("actors.Id" or "actors.Name"). However, in your scenario it is not possible to specify the exact field, because actors.Id and actors.name are not accessible for all items in the data source(in some of the items "actors" is null ). You can see an example that if provide data for "actors" in all items, the grouping functionality will work as expected.

Additional information for this limitation could be found also here.

Hi,

   I will log it, but for now, I have no solution.  I tried this solution, but it does not works.

I always have this client error without and with your changes and only with this column containing nulls...

angular2-polyfills.js:143 Uncaught SyntaxError: Unexpected identifier

 

Thank you for your help

Hello Steve,

As I mentioned in my previous post, the desired behavior is not supported. Unfortunately, I am not able to provide a workaround for this behavior, because currently there is no a good solution for such scenario.
