context menu
Could you consider implementing a component for adding a "contextmenu" to any kind of markup/components. This is very important for more packed UIs and business applications.

FilterRow with DetailTemplate throws in 2.15.0

 

This error appears after update 15, in 14.1 it works correctly.

 

ADMIN EDIT:

This error occurs from the FilterMode set to FilterRow. As a workaround, until the fix is implemented, you could use the FilterMenu instead.

 

Regards

Create a toggle switch for Blazor UI
It would be nice to have a toggle switch available in the UI for Blazor components. The component could support true/false and have customized text for each value.

The test2 component created by me is this one It only includes a telerikdropdown

@using Olympus.Artemis.Shared
<TelerikComboBox Data="@Items" Value="@Value" ValueField="ID" OnChange="@OnChange" TextField="Date">

</TelerikComboBox>
@code {


    [Parameter]
    public EventCallback<Object> OnChange { get; set; }

 

    [Parameter]
    public Guid Value { get; set; }

    [Parameter]

    public DataSource<WeatherForecast> DataSource { get; set; }

    private IEnumerable<WeatherForecast> Items { get; set; } = new List<WeatherForecast>();
    protected async override Task OnInitializedAsync()
    {
        Items = await DataSource.GetDataAsync();

        await base.OnInitializedAsync();
    }


}

But when i try to select something from the dropdown list the grid cel does not close gracefully 

I get this error (the problem is when it executed the line   await _grid?.SetState(state);)

The test control is a simplified version of a more complex control i was trying to create (mutlicolumn combobox)

If I instead use the telerikdropdown in editortemplate everything works ok

Create a chips component for Blazor UI
One feature that is missing from the current set of Blazor UI components is a chips control. I'm not sure if it's OK to link to 3rd party controls, but this is a fairly common control that is available on multiple platforms. I can provide some samples if required.

ListView component
I would like a simple list with templates for my items. Much like the grid, but not confined to cells and rows.
