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;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

public partial class videoPlayer : System.Web.UI.UserControl

How to use the above control? 

Default.aspx

<div align="center">

<whPlayer:vaPlayer ID="videoPlayer" autoStart="true" runat="server" />

<br />

<asp:ValidationSummary id="valSumm" runat="server" />

<asp:Label ID="lblVideoName" Text="Enter Video Name" runat ="server" />

<asp:TextBox ID="txtVideoName" runat="server" EnableViewState="true" Text="D:\Videos\AVSEQ06.DAT" />

<asp:Button ID="btnPlayVide" runat="server" OnClick="btnPlayVide_Click" Text="Play Video" />

<asp:RequiredFieldValidator id="rfvtxtVideoName" ControlToValidate="txtVideoName" text="*" ErrorMessage="Please eneter Video to play" runat="server" />

</div>

Default.aspx.cs

protected void Page_Load(object sender, EventArgs e)

{

if (Request.QueryString["sourceUrl"] != null)

this.videoPlayer.sourceUrl = Convert.ToString(Request.QueryString["sourceUrl"]);

videoPlayer.autoStart = true;

videoPlayer.height = "300";

videoPlayer.width = "300";

}

protected void btnPlayVide_Click(object sender, EventArgs e)

{

if(IsValid)

Response.Redirect("videoplayercustomcontrol.aspx?sourceUrl=" + txtVideoName.Text);

}

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