Create a table in a SQL Server.
Create table Videos
(
ID Int identity,
Video varbinary(MAX),
Video_Name nvarchar(50),
Video_Size bigint
)

Tools
Drag and Drop FileUpload Control, Button,Lable,
Panel and inside the panel drag and drop Repeater Control.
Change the text property of BtnUpload control to Upload.
Code
1. Save Data in DataBase. Here data may be Video file, Image file or audio
file. On click event of upload button write down the following code.
using
System;
using
System.Collections.Generic;
using
System.Linq;
using
System.Web;
using
System.Web.UI;
using
System.Web.UI.WebControls;
using
System.Data.SqlClient;
using
System.Data;
public
partial class
_Default : System.Web.UI.Page
{
protected void Page_Load(object
sender, EventArgs e)
{
}
byte[] buffer;
SqlConnection connection;
protected void BtnUpload_Click(object
sender, EventArgs e)
{
if (FileUpload1.HasFile &&
FileUpload1.PostedFile != null
&&
FileUpload1.PostedFile.FileName != "")
{
HttpPostedFile file = FileUpload1.PostedFile;
//retrieve the HttpPostedFile object
buffer =
new byte[file.ContentLength];
int bytesReaded = file.InputStream.Read(buffer,
0,
FileUpload1.PostedFile.ContentLength);
if (bytesReaded > 0)
{
try
{
connection = new
SqlConnection("Data Source=.;Initial Catalog=Sample;User
Id=sa;Password=faculty");
SqlCommand cmd = new
SqlCommand
("INSERT
INTO Videos (Video, Video_Name, Video_Size)" +
"
VALUES (@video, @videoName, @videoSize)", connection);
cmd.Parameters.Add("@video",
SqlDbType.VarBinary, buffer.Length).Value =
buffer;
cmd.Parameters.Add("@videoName",
SqlDbType.NVarChar).Value =
FileUpload1.FileName;
cmd.Parameters.Add("@videoSize",
SqlDbType.BigInt).Value = file.ContentLength;
using (connection)
{
connection.Open();
// int i = cmd.ExecuteNonQuery();
cmd.ExecuteReader();
Label1.Text = "uploaded";
}
}
catch (Exception
ex)
{
Label1.Text = ex.Message.ToString();
}
finally
{
connection.Close();
}
}
//Response.Redirect(Request.Url.AbsoluteUri);
}
else
{
Label1.Text =
"Choose a valid video file";
}
}
The above code will help you to save your data in database.Notice one thing, if
your data is large in size then you need to increase maxRequestLength in
web.config under System.web node.
<system.web>
<httpRuntime maxRequestLength="2097151" />
2. Select Data and show it on your Page.
Here we are going to use Player Control to display data on your page. But our
file exists in a database, so we need a handler to read the bytes in the
database. you can call handler like handler.ashx?Id=1. Id=1 is a query string.
So Next step is add Handler to your Project and name it as VideoHandler.ashx.
This handler is going to retrieve data from database.
Code
using
System;
using
System.Web;
using
System.Data.SqlClient;
using
System.Data.SqlTypes;
using
System.Data;
public
class VideoHandler
: IHttpHandler
{
// SqlConnection connection;
public void ProcessRequest(HttpContext
context)
{
SqlConnection connection =
new SqlConnection("Data
Source=.;Initial Catalog=Sample;User Id=sa;Password=faculty");
SqlCommand cmd = new
SqlCommand("SELECT
Video, Video_Name" + " FROM Videos WHERE ID =
@id", connection);
cmd.Parameters.Add("@id",
SqlDbType.Int).Value =context.Request.QueryString["id"];
try
{
connection.Open();
SqlDataReader reader = cmd.ExecuteReader(CommandBehavior.Default);
if (reader.HasRows)
{
while (reader.Read())
{
context.Response.ContentType = reader["Video_Name"].ToString();
context.Response.BinaryWrite((byte[])reader["Video"]);
}
}
}
finally
{
connection.Close();
}
}
public bool IsReusable
{
get
{
return false;
}
}
}
3. Show Video on Page.
You have to read the data from the SQL Server with a SQL adapter and bind the
data source to the Repeater control. Well, here you can specify which videos to
select in the datasource..
Add one textBox and Button right above the Panel. Change the text property of
button to Show Video. This textbox we are going to use to enter Id of
video.Finally on click event of ShowVideo button we are going to display video
on page.
So here we will create one method, this will retrieve data from sqlserver
private
DataTable GetSpecificVideo(object i)
//pass the id
of the video
{
connection =
new SqlConnection("Data
Source=.;Initial Catalog=Sample;User Id=sa;Password=faculty");
SqlDataAdapter
adapter = new
SqlDataAdapter("SELECT Video, ID " +
"FROM
Videos WHERE ID = @id", connection);
adapter.SelectCommand.Parameters.Add("@id",
SqlDbType.Int).Value = (int)i;
DataTable
table = new
DataTable();
adapter.Fill(table);
return
table;
}
On click event Bind this data to repeater Control...
protected void Button1_Click(object sender, EventArgs e)
{
int id = Convert.ToInt32(TextBox1.Text);
Repeater1.DataSource = GetSpecificVideo(id);
Repeater1.DataBind();
}
Now we will add Palyer control. In source view of Repeater Control add an
Itemtemplate
<asp:Panel
ID="Panel1"
runat="server"
Height="126px"
Width="881px">
<asp:Repeater
ID="Repeater1"
runat="server">
<ItemTemplate>
<object
id="player"
classid="clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6"
height="300"
width="300">
<param
name="url"
value='<%#
"VideoHandler.ashx?id=" + Eval("ID") %>'/>
<param
name="showcontrols"
value="true"
/>
<param
name="autostart"
value="true"
/>
</object>
</ItemTemplate>
</asp:Repeater>
</asp:Panel>
Run your application . Now you can upload file as well as show
your uploaded video file on page.
