Some days ago, I faced a little problem while trying to show streaming contents on my Web-Projects. I went through many R&d’s and then decided to write a custom control for the same. This code sample is that of the custom control I wrote.
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, let us start to write code-behind as follows:
File Name : videoPlayer.ascx.cs
