Upload/Download file in server

Hi,

These article said to posses 

   1) A file uploader

                   Which is used for uploading files to server

   2)A grid view

                Whic is used to store the uploaded file to te user and to delete it.

step1: Place a uploader in design page and write a coding as

protected void Button1_Click(object sender, EventArgs e)
    {
        if (FileUpload1.HasFile)
        {
           
            fname = FileUpload1.FileName;
            spath = @"~\ssg\" + FileUpload1.FileName;
            fpath = Server.MapPath("ssg");
            fpath = fpath + @"\" + FileUpload1.FileName;            
            desc = TextBox2.Text;
            if (System.IO.File.Exists(fpath))
            {
                Label1.Text = "File Name already exists!";
                return;
            }
            else
            {
                FileUpload1.SaveAs(fpath);
            }
            //Store details in the SQL Server table
            StoreDetails();
            TextBox2.Text = "";
//Refresh grid
            LoadGrid();
        }
        else
        {
            Label1.Text="Please select file!";
        }
    }

step 2: Now for loading grid and storing details write coding as

void LoadGrid()
    {
        sqlcon.Open();
        sqlcmd = new SqlCommand("select * from fileDet", sqlcon);
        da = new SqlDataAdapter(sqlcmd);
        dt.Clear();
        da.Fill(dt);
        if (dt.Rows.Count > 0)
        {
            GridView1.DataSource = dt;
            GridView1.DataBind();
        }
        else
        {
            GridView1.DataBind();
        }
        sqlcon.Close();
    }

Main concept behind this is

During uploaded time i have store the server path in the SQL Server.

 I had bind server path in Grid View Hyper link (Navigate URL).

Then bind in grid view If user click the file name in the grid view then files are downloaded.

NOTE: Create the folder named ssg in your application
