</td></tr></table>
</div>
</form>
my code behind :
protected void Button 1_Click(object sender, EventArgs e)
{
// Read the file and convert it to Byte Array
string filePath = FileUpload1.PostedFile.FileName;
string filename = Path.GetFileName(filePath);
string ext = Path.GetExtension(filename);
string contenttype = String.Empty;
Image1.ImageUrl = filename;
//Set the contenttype based on File Extension
switch (ext)
{
case ".doc":
contenttype = "application/vnd.ms-word";
break;
case ".docx":
contenttype = "application/vnd.ms-word";
break;
case ".xls":
contenttype = "application/vnd.ms-excel";
break;

contenttype = "application/pdf";
break;
}
if (contenttype != String.Empty)
{
Stream fs = FileUpload1.PostedFile.InputStream;
BinaryReader br = new BinaryReader(fs);
Byte[] bytes = br.ReadBytes((Int32)fs.Length);
//insert the file into database
string strQuery = "insert into empimage(Name, ContentType, Data)" +
" values (@Name, @ContentType, @Data)";
SqlCommand cmd = new SqlCommand(strQuery);
cmd.Parameters.Add("@Name", SqlDbType.VarChar).Value = filename;
cmd.Parameters.Add("@ContentType", SqlDbType.VarChar).Value
= contenttype;
cmd.Parameters.Add("@Data", SqlDbType.Binary).Value = bytes;
InsertUpdateData(cmd);
Label1.ForeColor = System.Drawing.Color.Green;
Label1.Text = "File Uploaded Successfully";
}
else
{
Label1.ForeColor = System.Drawing.Color.Red;
Label1.Text = "File format not recognised." +
" Upload Image/Word/PDF/Excel formats";
}
}
private Boolean InsertUpdateData(SqlCommand cmd)
{
pd = ConfigurationManager.ConnectionStrings["su"].ConnectionString;
con = new SqlConnection(pd);
//String strConnString = System.Configuration.ConfigurationManager
//.ConnectionStrings["conString"].ConnectionString;
//SqlConnection con = new SqlConnection(strConnString);
cmd.CommandType = CommandType.Text;
cmd.Connection = con;
try
{
con.Open();
cmd.ExecuteNonQuery();
return true;
}
catch (Exception ex)
{
Response.Write(ex.Message);
return false;
}
finally
