Hi,

will there be a focusout-event in the future? Similar to the focusout-event of html-input...

I want to do something after leaving a row.

Lots of greetings

I have a new project that requires real-time data updates on a grid for a team of users to collaborate within the application.

It seems SignalR is a good candidate for this project. I am new to programming with SignalR. Since I am familiar with .NET 4.x framework and MVC, I initially was thinking of implementing the project as an ASP.NET Core 3.0 MVC with Telerik.UI for Asp.Net Core since it has Grid Binding to SignalR.

However, with the release of Blazor, I am considering using Blazor and Telerik.UI.for.Blazor. But I don't see any samples or documentations to use with SignalR in Telerik.UI. 

My questions:

1. Given that my project requires SignalR for real-time data updates, should I choose the stable approach of ASP.NET Core with MVC and the more-documented Telerik.UI for asp.net Core grid ? or is it possible to use Blazor / SignalR / Telerik.UI (if such thing exists) ? What are the pros vs. cons of those 2 choices?

2. Where can I find tutorials on building:
1) ASP.NET Core 3.0 MVC / SignalR / Telerik for ASP.NET Core;
2) ASP.NET Core Blazor / SignalR / Telerik for Blazor

Hello,

I have blazor grid inside my custom component. I need to call InvokeAsync method on my EventCallback passed to this component. When I do that from SelectedItemsChanged event app gets crashed without any exception. I read the docs about async operations in this event (https://docs.telerik.com/blazor-ui/components/grid/selection/overview#asynchronous-operations), but don't know how to workaround this.

Hey all,
I'm working on a wrapper for the KendoUI color picker to allow users more control over the colors of how their data is being represented.
So the overall flow will be, given a dynamic list of data, create a color picker for each one, passing an object reference for that specific item. Then, upon a color being picked, call a function on that object to update it's color property with the selection.
My problem being that I can't figure out how to get the object reference into the color changed event. I thought using JS protoyped functions would work (because I need each color picker to have it's own scope so it knows which object's function to call) but 'this' inside of ColorPickerWidget is scoped to the window instead of to ColorPickerWidget. 

Any suggestions would be appreciated!

JS functions:
function ColorPickerWidget(bindTo, objRef) {
    var objectRef = objRef;
    this.create(bindTo);
};

ColorPickerWidget.prototype.create = function(bindTo) {
    $(bindto).kendoColorPicker({
        value: "#ffffff",
        buttons: false,
        select: this.selectColor
    });
}

ColorPickerWidget.prototype.selectColor = function(e) {
    this.objectRef.invokeMethodAsync("ChangeColor", e.value);
}

.NET Functions:
protected async override Task OnInitializedAsync()
        {
            await JsRuntime.InvokeVoidAsync(identifier: "ColorPickerWidget", elRef, DotNetObjectReference.Create(this));
        }

        [JSInvokable]
        public void ChangeColor(string color)
        {
            Color = color;
            ColorChanged.InvokeAsync(color);
        }

Hi
I am just learning/testing with Blazor and have created a standard Blazor Server App, using the default template built into VS 2019.  Is there a simple way I can convert this to a Telerik Blazor app?  For exampe copy over some DLLs or maybe install a nuget package?

Or do I have to start from scratch and use the Telerik Blazor built into VS Studio?

Manythanks in advance

Hi,

I have a calendar control with initial date. It could be "Today" or any other date. The Calendar works fine but the initial date is not visually selected. If I click on any date it's get selected and displayed in "red" but I need it selected initially without user intervention.

                                <TelerikCalendar SelectionMode="@CalendarSelectionMode.Single"
                                                 ValueChanged="@( (DateTime d) => OnBeginDateChangeHandlerAsync(d) )"
                                                 Min="@beginmin" Max="@beginmax"
                                                 @bind-Date="@begindate">
                                </TelerikCalendar>

@code {
    protected DateTime begindate { get; set; } = DateTime.Now.AddDays(-8).Date;

}

Thanks.

Hi,

Is there any way to disable all weekends on Calendar control? Yes, I could create a list of disable dates but it will be a huge list. I just curious if there is some setting to do that.

Thanks.

I've used your example code to adjust the font size on a grid and been using rowheight to adjust the row height but there appears to be some limit as too how small you can make the row height.

I've attached a screen shot which shows there is a lot of space in the row above and below the small text, can this be reduced?

Cheers

Steve
