Notification controls
The Notifications component I think would be a great addition to UI for Blazor!  
Use it quite often with SPAs

A perfect example of what we want for the standalone Toast control is like this one:

I am using Blazored Toast control which is an open source, so no problem about that. But, it will be nice to stick to one library rather than using many different nuget packages for UI purpose. So, I would like to see such control in Telerik Suite.

Additional features I'd like to see are:

  • A Duration parameter that indicates how long the notification should be visible.

    The notification should automatically disappear after the duration is reached.  This would save us from having to call HideAsync().
  • Ability to stack multiple notifications and have them float to the top as ones above it disappear.

    Currently the only way to position notifications is to use the Top and Left parameters and I suppose we'd have to do some CSS calculation to stack them dynamically.

Hello Tyler,

You can use the font icons from the Kendo suite in Blazor as well, as the SASS themes are shared. Here's an example:

@using Telerik.Blazor
@using Telerik.Blazor.Components.AnimationContainer
@using Telerik.Blazor.Components.Button
<TelerikButton OnClick="@Show">Show Notification</TelerikButton>
<div style="position: absolute; top: 50%; left: 50%">
    <TelerikAnimationContainer @ref="@AnimationContainer" Width="300px" Height="200px" AnimationType=@AnimationType.Fade>
        <div class="k-widget k-popup k-notification k-notification-info">
            <div class="new-mail">
                <h3><span class="k-icon k-i-info"></span>New E-mail</h3>
                    <span class="k-icon k-i-info"></span>
                    You have 1 new mail message!
@code {
    public TelerikAnimationContainer AnimationContainer { get; set; }
    public async void Show(UIMouseEventArgs args)
        await AnimationContainer.ShowAsync();
        await Task.Delay(2000);
        await AnimationContainer.HideAsync();
<style type="text/css">
    .new-mail .k-icon {
        font-size: inherit;
        /* this will make the icon large as its text container
        and you may want to tweak this further with different/more specific rules

On a close button - you just need to add an element whose click will call AnimationContainer.HideAsync().

I hope this helps you move forward for the time being.

Considering that most of these features can easily be achieved with the current components, I am not sure if this will be implemented soon, or if at all, yet I am going to keep it open so we can gather the community feedback and interest. As usual, if sufficient public interest is accrued, its priority will rise.

That could work. 
I think it would be nice to have some of the styling built-in like the Title Icon, Title Bar & Close button.
This be an optional element.

Hi Tyler,

You can use the AnimationContainer component for this, as shown in this demo:

What are the other features you would like to see in a standalone component of this type that cannot be done with this approach?
