Grid.SetState() doesn't work with observable collection

[Bert]

Hello,

 

when I try to sort a grid, bound to an observable collection, it doesn't work. The function SetState does not exit

 

Best Regards

Hi Bert,

The following seems to work fine for me with the current latest 2.13.0. Am I missing something, or do you have a different scenario?

 

@using Telerik.DataSource;
@using System.Collections.ObjectModel

<TelerikButton Primary="true" OnClick="@SetGridSort">set sort from code</TelerikButton>

<TelerikGrid Data="@MyData" Height="400px" @ref="@Grid"
             Pageable="true" Sortable="true">
    <GridColumns>
        <GridColumn Field="@(nameof(SampleData.Id))" Width="120px" />
        <GridColumn Field="@(nameof(SampleData.Name))" Title="Employee Name" />
        <GridColumn Field="@(nameof(SampleData.Team))" Title="Team" />
        <GridColumn Field="@(nameof(SampleData.HireDate))" Title="Hire Date" />
    </GridColumns>
</TelerikGrid>

@code {
        public TelerikGrid<SampleData> Grid { get; set; }

        async Task SetGridSort()
        {
            GridState<SampleData> desiredState = new GridState<SampleData>()
            {
                SortDescriptors = new List<SortDescriptor>()
                {
                    new SortDescriptor { Member = "Id", SortDirection = ListSortDirection.Descending }
                }
            };

            await Grid.SetState(desiredState);
        }

        public ObservableCollection<SampleData> MyData { get; set; } = new ObservableCollection<SampleData>( 
            Enumerable.Range(1, 30).Select(x => new SampleData
             {
                Id = x,
                Name = "name " + x,
                Team = "team " + x % 5,
                HireDate = DateTime.Now.AddDays(-x).Date
            })
        );

    public class SampleData
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Team { get; set; }
        public DateTime HireDate { get; set; }
    }
}

I tried again and now it works.

I don't know why it didn't work before.

Thanks anyway and sorry for the the trouble

No worries, Bert, it's best to check and if it's a bug that gives us the chance to improve the component. If it does come up again, let us know.
