+## Description
+
+I want to auto-play an MP4 video with sound on page load and make the video player disappear after the video has finished playing. The goal is to play a short welcome video by the owner that automatically hides itself upon completion.
+
+This KB article also answers the following questions:
+
+- How can I make RadMediaPlayer auto-play a video?
+- Is it possible to hide RadMediaPlayer after the video ends?
+- Can RadMediaPlayer start playing a video automatically and then hide itself?
+
+## Solution
+
+To achieve the desired behavior of auto-playing a video and hiding the [RadMediaPlayer](https://docs.telerik.com/devtools/aspnet-ajax/controls/mediaplayer/overview) after it ends, use the `OnClientEnded` [client-side event](https://docs.telerik.com/devtools/aspnet-ajax/controls/mediaplayer/client-side-programming/overview#client-side-events). In the event handler, you can set the visibility of the RadMediaPlayer to `false`.
+
+Add the RadMediaPlayer control to your ASP.NET AJAX page. 
+
+````ASP.NET
+<telerik:RadMediaPlayer RenderMode="Lightweight" ID="RadMediaPlayer1" runat="server" Width="640px" Height="360px"
+    Source="https://www.example.com/path/to/your/video.mp4" OnClientEnded="onClientEnded" />
+````
+
+Define the `onClientEnded` JavaScript function. This function will be triggered when the video playback ends, hiding the RadMediaPlayer control.
+
+````JavaScript
+function onClientEnded(sender, args) {
+    sender.set_visible(false);
+}
+````
+
+By following these steps, the RadMediaPlayer will automatically begin playing the video when the page loads and will hide itself after the video concludes, achieving the effect of a welcoming video that disappears post-playback.
