Grouping by a nested (child) Grid column is not possible in OnStateInit.

A possible workaround is to group in OnAfterRenderAsync.

@using Telerik.DataSource

<TelerikGrid Data=@GridData @ref="TheGrid"
             Groupable="true"
             OnStateInit="@((GridStateEventArgs<User> args) => OnStateInitHandler(args))">
    <GridColumns>
        <GridColumn Title="Personal Information">
            <Columns>
                <GridColumn Field=@nameof(User.LName) Title="Last Name" />
                <GridColumn Field=@nameof(User.FName) Title="First Name" />
            </Columns>
        </GridColumn>
        <GridColumn Title="Status and Last Login">
            <Columns>
                <GridColumn Field=@nameof(User.StatusName) Title="StatusName" />
                <GridColumn Field=@nameof(User.LastLoginDate) Title="Last Login" DisplayFormat="{0:yyyy-MMM-dd}" />
            </Columns>
        </GridColumn>
    </GridColumns>
</TelerikGrid>

@code {
    TelerikGrid<User> TheGrid { get; set; }
    List<User> GridData { get; set; }

    protected override void OnInitialized()
    {
        var data = new List<User>();
        for (int i = 1; i <= 20; i++)
        {
            data.Add(new User()
            {
                Id = i,
                FName = "First Name " + i,
                LName = "Last Name " + i,
                StatusId = i * 123,
                LastLoginDate = DateTime.Now,
                StatusName = "Status Name " + (i % 5 + 1)
            });
        }
        GridData = data;
    }

    private void OnStateInitHandler(GridStateEventArgs<User> args)
    {
        GridState<User> desiredState = new GridState<User>()
        {
            GroupDescriptors = new List<GroupDescriptor>()

                new GroupDescriptor()
                {
                    Member = nameof(User.StatusName),
                    MemberType = typeof(string)
                }
            }
        };

        // will trigger an exception if grouping by a nested column
        args.GridState = desiredState;
    }

    @*protected override async Task OnAfterRenderAsync(bool firstRender)
    {
        if (firstRender)
        {
            var desiredState = TheGrid.GetState();

            desiredState.GroupDescriptors = new List<GroupDescriptor>()
            {
                new GroupDescriptor()
                {

                    MemberType = typeof(string)
                }
            };

            await TheGrid.SetState(desiredState);
        }

        await base.OnAfterRenderAsync(firstRender);

    public class User
    {
        public long Id { get; set; }

        public int StatusId { get; set; }
        public string StatusName { get; set; }

        public string FName { get; set; }
        public string LName { get; set; }

        public DateTime LastLoginDate { get; set; }
    }
}

GridCheckBoxColumn:  The check disappears when focus is on a editable cell.

Allow the Grid to support Enums which are mapped to use datatypes different from int. Currently, if I try to use the following Enum, an InvlidCastException is generated:

public enum ShortEnum : short
{
    Value1,
    Value2,
    Value3
}

Using OnRowDrop works fine but there is no configuration possible to set the column at the end of the grid.

Of course it's a personnal taste but I like to have the all the actions buttons on the right side

If the window component does not implement a Width parameter, it will seem like docked to right when dragging. The issue stems from the update of top and left styles while the width of the component grows with them.

1. Open the repl

2. Initiate dragging

**Workaround**

Set the Width parameter of the Window component

Hello,

My Grid is setting filters in OnStateInit. Then, the filters are cleared via GridRef.SetState(null)

This used to work until 3.0.1, but not in 3.1.0. Here is a test page:

Does the Blazor grid have any support for any or all queries on sub-property collections? I would like to have the grid OnRead be able to generate a query against a sub-entity collection.

E.g.

GET serviceRoot/People?$filter=Emails/any(s:endswith(s, 'contoso.com'))

From what I can tell the Column.FieldName property only will generate a valid query for scalar properties. Is there any way to make this work?

Given the Northwind OData sample https://demos.telerik.com/kendo-ui/service-v4/odata. I would like to display a grid of all customers. In the grid, I would like to have a column that provides filtering for the orders shipper column as in the query below.

https://demos.telerik.com/kendo-ui/service-v4/odata/Customers?$expand=Orders&$filter=Orders/any(d: contains(d/Shipper/CompanyName,'Speedy Express'))

There does not seem to be a way for the in-built filter mechanism to use a lambda and it seems like there should be.

When you type something in the grid searchbox, there will be a X at the end to clear the box.

However, if you restore the grid from previously stored state like localstorage, and if the box has value, the X is not there.

Thanks!

Hi, how to show a pointer cursor while mouse over the group arrow icon? I could probably set style="cursor: pointer", but just wondering if there is any other approach. Thanks.

I would like to be able to customize the title in Editing Popup. 

<AdminEdit>

We plan to expose the following customization options:

• Title,
• Width
• Height
• MaxWidth
• MaxHeight

</AdminEdit>

Sometimes, we just want a simple equal filter in grid, without operators options

ADMIN EDIT

If you want to modify the current behavior and layout of the filters, use the filter template (there is another example in this thread - in the post from 29 Jun 2020 that you can also use as base).

Hello,

If the Grid has X columns at first, and then it renders Y more columns, the new Y columns will not be resizable. Here is a test page.

A possible workaround is to define all columns initially, but hide some of them with Visible="false".

This worked in 2.29 and broke in 2.30.
