A VideoPlayer - Custom Control in ASP.Net
Some day ago, I have faced a little problem to show streaming contents on my Web-Projects, I have gone through many R & d's and then decided to write a custom control for the same, then I have written a custom control.
Here, the same, I want to share with you:
File Name : videoPlayer.ascx
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="videoPlayer.ascx.cs" Inherits="videoPlayer" %>
< asp:PlaceHolder ID="phError" runat="server" Visible="false">
<asp:Label ID="lblError" runat="server" ForeColor="Red" Text="Error" />
</ asp:PlaceHolder>
< asp:Table ID="tblPlayer" runat="server" BorderWidth="1">
<asp:TableRow>
<asp:TableCell>
<asp:Literal ID="ltVideo" runat="server" />
</asp:TableCell>
</asp:TableRow>
</ asp:Table>
Now, lets start to write code-behind as follows:
File Name : videoPlayer.ascx.cs
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;

using System.Web.UI.HtmlControls;

How to use the above control?

To play video, send the path of the video as a querystring to default.aspx.
