If one wanted to use .net core 3.0 is there a version of UI for Blazor one could use?

Just updated to Telerik.UI.for.Blazor 2.2.1, but was having the problem before updating as well.  I suspect its just something Im missing.

This section
https://docs.telerik.com/blazor-ui/getting-started/server-blazor

When I load my page, im getting 404 errors in the dev console for telerik-blazor.js.  I am adding dependencies to an existing Blazor project I started.
We have the private nuget feed setup.  So that much looks right.  What am I missing? 

This is in _Host.cshtml

This is my MainLayout.cshtml

 I have tried to implement the dropdownlist and the data is being populated to the control, but the control will not dropdown when selected on.

I have tried to changed from Server/Prerender and also tried a static list. I also have the same issues with Telerik menus. What do I have configured wrong.

Running Blazor UI 2.1.1

<TelerikDropDownList Data="@DropDownListData" @bind-Value=@SelectedValue ValueField="ID" TextField="Organization">

</TelerikDropDownList>

<br />Selected product: @SelectedValue



@code {

    public IEnumerable<OrgModel> DropDownListData { get; set; }

    public int SelectedValue { get; set; } = 3;

    WeatherForecast[] forecasts;
    OrgModel[] Orgs;

    protected override async Task OnInitializedAsync()
    {
        forecasts = await ForecastService.GetForecastAsync(DateTime.Now);
        DropDownListData = await OrgService.Get_OrgList_Async();
    }

    //protected async Task OnAfterRenderAsync()
    //{
    //    forecasts = await ForecastService.GetForecastAsync(DateTime.Now);
    //    DropDownListData = await OrgService.Get_OrgList_Async();
    //}

I have a parent component when contains a child component with a TelerikChart.  Using cascading parameters, when I change a value in the parent component it cascades to the child and I rerun queries to create the proper data for the chart.  Often times, but no all the time, a chart will rerender with some of the old data mixed in with some of the new data, even though the data model only contains the new data.

Is there a way to force the chart to totally clear out before rerendering?

For example, the menu component.  Where are all the available attributes and events listed for this component. Yes, I see in the examples a "Data" and "orientation" attribute are used, but seems this should be explained in an "api" section for each component?

I see the API Reference link but this seems like just a dump of the entire library, rather than a component-by-component reference?

However, same goes for the other components as well.

There is a note on the documentation page for NumericTextBox saying "The decimal separator is . for the time being. When localization features get implemented in the Telerik UI for Blazor suite... Currency symbols are also rendered by the framework and they come from the current culture as well."

Is that note still relevant?

I made a simple test..

<TelerikNumericTextBox @bind-Value="Number" Format="C"></TelerikNumericTextBox>

@code {
    public decimal Number { get; set; } = (decimal)2.59;
    protected override void OnInitialized()
    {
        System.Globalization.CultureInfo.DefaultThreadCurrentCulture = new System.Globalization.CultureInfo("hr-HR");
    }
}

The numer in numeric text box is displayed as expected - "2,59 kn"  (Notice that it has the correct decimal separator and currency simbol)
When I want to change the number I cannot input "," (comma) as a decimal separator - numericTextBox won't accept it.
So I tried with "." (dot).
I can input "." (dot) but when I enter a number after "." the "." disappears leaving me with an whole number in numericTextBox.

Is this a bug or a missing feature? The note above is confusing because NumericTextBox get's it's formating options from current culture so why doesn't it apply the correct decimal separator?

Thank you

I am seeing that the grid filter mode causes the following exception to be thrown: "System.InvalidOperationException: JavaScript interop calls cannot be issued at this time. This is because the component is being prerendered and the page has not yet loaded in the browser or because the circuit is currently disconnected. Components must wrap any JavaScript interop calls in conditional logic to ensure those interop calls are not attempted during prerendering or while the client is disconnected."

Steps to reproduce (project using example from https://docs.telerik.com/blazor-ui/components/grid/overview is at https://github.com/austineric/GridTest):

1. Open solution
2. Ctrl + F5
3. In the address bar add "/test" to the url
4. In Visual Studio change the output to "GridTest - ASP.NET Core Web Server"
5. Clear All in the output window
6. Refresh the browser page
7. View the exception in the output window
8. Run the same test but remove the "FilterMode="Telerik.Blazor.GridFilterMode.FilterRow"" and see that the exception does not appear

Error produced using

• .Net Core 3.0.100
• Telerik UI for Blazor 2.2.1
• Visual Studio 16.3.5

The grid appears to be working and filtering correctly despite the exception. Should I disregard? Should I be doing something differently?
