At the moment, the CollapsedGroups  collection in the grid state is the indexes of the root-level groups that you can collapse. I want to also be able to control the expanded state of nested groups.

ADMIN EDIT:

Ideas I can see are the following, do add your vote and comments on how you expect that to be exposed:

• a form of Id/field in the group descriptor that controls this. Caveat - groups don't generally have such an id and the descriptor does not control the UI, it controls the data.
• an event that provides the level, field name and group value that lets me choose this for every group as it renders. Caveat - might not plug in the state, but if you have a certain business logic for that you can just keep it in that event always, regardless of the grid state, or keep additional information in an application state.
• the current indexes could become recursive (see the image attached below). Caveat: you can't be sure that the next time data loads the data and so the groups will be the same when loading state

For example, when I have two levels of grouping, I want to render only the inner footer templates, but not the outer.

While this is possible with some CSS like the snippet below, this does not scale well, and does not work well for arbitrary number of groups

<style>
    .k-group-footer + .k-group-footer {
       display:none;
    }
</style>

Group by the Vacation and Team columns to see the effect

<TelerikGrid Data=@GridData Groupable="true" Pageable="true">
    <GridColumns>
        <GridColumn Field=@nameof(Employee.Name) Groupable="false" />
        <GridColumn Field=@nameof(Employee.Team) Title="Team">
            <GroupFooterTemplate>
                Team group footer
            </GroupFooterTemplate>
        </GridColumn>
        <GridColumn Field=@nameof(Employee.IsOnLeave) Title="On Vacation">
            <GroupFooterTemplate>
                IsOnLeave group footer
            </GroupFooterTemplate>
            </GridColumn>
    </GridColumns>
</TelerikGrid>

@code {
    public List<Employee> GridData { get; set; }

    protected override void OnInitialized()
    {
        GridData = new List<Employee>();
        var rand = new Random();
        for (int i = 0; i < 15; i++)
        {
            GridData.Add(new Employee()
            {
                EmployeeId = i,
                Name = "Employee " + i.ToString(),
                Team = "Team " + i % 3,
                IsOnLeave = i % 2 == 0
            });
        }
    }

    public class Employee
    {
        public int EmployeeId { get; set; }
        public string Name { get; set; }
        public string Team { get; set; }
        public bool IsOnLeave { get; set; }
    }
}

I would like to start the tree grid with all rows collapsed. At the moment I can do this only through load on demand.

I have a requirement to design our own custom add/edit template form for scheduler control.

I looked at  custom edit form example and found very helpful, However this example does not demonstrate how to use RecurrenceEditor and use them in custom template.

how to use Multiple Column Header in grid?

thanks

I want to edit the Excel file the grid exports before it gets to the user. For example, to add a sheet with data I want to generate, or to change columns, formats, colors.

----

ADMIN EDIT

I have attached to this post an example that shows how you can generate your own exported file so you can customize colors, sheets and so on. It also shows how to cache the DataSourceRequest of the grid so you can extract only the current page or all data, and so you can also apply the current grid sorts/filters and so on to the export. This also lets you add metadata to the sheet such as the current user settings such as filters that resulted in this filter.

Please add a feature to export the grid to Microsoft Word file

---

ADMIN EDIT:

I am attaching a sample to this post that you can use to generate the docx file through the Telerik Document Processing libraries by looping over the data.

You can extend it further (add more fields, refactor so it is more reusable, extract to service,...) and if you would like to export the current grid data, see about implementing the data operations manually through the OnRead event - you can cache the DataSourceRequest object and then run a .ToDataSourceResult() query on the data to get what the grid displays on its current page. An example of a similar approach is available here for a customized excel export.

You can also read more about working with tables in a Word document here to apply more styling options as needed.

Hi !

How can i hide some columns on small device ?

Telerik.Blazor.Components.GridColumn.Class does not exist ?

Regards,

Is it possible to do group scheduling similar to what is done https://demos.telerik.com/aspnet-mvc/scheduler/resources-grouping-horizontal.

If not how do i include kendo in a serverside blazor application?

Cheers

Ian

I want to change what is shown in the scheduler headers, depending on my current culture, and on the view (different things for a week view and for a day view, for example).
