[Solved] Grouping by Column Template

[Scott]

I am using the MVC Extensions Grid and have an embedded Grid which uses a combination of bound columns and template columns.  Is it possible to group by a template column, if so how?  The following code produces an error: "memberName" cannot be null or empty.

Html.Telerik().Grid(Model.GetPrivileges(item.SSGOid.Value, item.SSGApplicationID))
                    .Name("TopicPrivileges")
                    .Columns(columns =>
                    {
                        columns.Bound(o => o.IsEnabled).Width(75).Title("Enable");
                        columns.Template(o => o.GetTopicDisplayName(Model, item.SSGApplicationID)).Width(200);
                        columns.Template(o => o.GetParentTopic(Model, item.SSGApplicationID)).Width(200).Title("Home Topic");
                        columns.Bound(o => o.ActionId).Width(150);

                    })
                            .Groupable(grouping => grouping.Groups(groups =>
                            {
                                groups.Add(o => o.GetParentTopic(Model, item.SSGApplicationID));
                            }))
                    .Pageable()
                    .Sortable()
                    .Filterable()

Thanks for any help.

Hi Scott,

Grouping/Paging/Filtering on template columns is not supported. You can bind your column to a model property and set its template instead - this way the paging/grouping will be applied according to the value of the binding property.
