how to create photo album in asp.net – Part II OR how to upload or add photo to album in asp.net

This article is the 2nd part of create photo album application. In this part I am going to explain how to upload or add photo to album in asp.net

In the first part I have explained how to create photo album in asp.net.

Description:
After created the album we will be redirected to upload/add photo page. On this page we will upload the image and uploaded image will be displayed below (in gridview) to enter description and click the save button to save the changes.

Implementation:
Create store procedure to save/insert the uploaded photo and get the id of last inserted record

Create PROCEDURE Sp_InsertPhoto
(
@albumid int,
@photopath varchar(max),
@id int output
)
AS
BEGIN
            SET NOCOUNT ON;

    Insert into Tb_Photo (AlbumId,PhotoPath) values (@albumid,@photopath)
set @id = SCOPE_IDENTITY() 
return @id 
END

Store procedure to get the data
Create PROCEDURE Sp_GetPhotoData
(
@id int
)
AS
BEGIN
            SET NOCOUNT ON;
Select * from dbo.Tb_Photo where photoid = @id
END

Store procedure to update the information/description
Create PROCEDURE Sp_UpdatePhoto
(
@id int,
@PhotoName varchar(100)
)
AS
BEGIN
            SET NOCOUNT ON;
    Update Tb_Photo set PhotoName=@PhotoName where PhotoID=@id
END

Add the namespace
C# Code:
using System.Data;
using System.Data.SqlClient;
using System.Configuration;

VB.net Code:
Imports System.Configuration
Imports System.Data.SqlClient
Imports System.Data

Create sqlconnection and set visibility false of save button on page load.
C# Code:
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["connection"].ToString());
    int id;
protected void Page_Load(object sender, EventArgs e)
    {       
        btnsave.Visible = false;
    } 

VB.net Code:
Private con As New SqlConnection(ConfigurationManager.ConnectionStrings("connection").ToString())
    Private id As Integer
  Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
        btnsave.Visible = False
    End Sub

Inserting the record and show uploaded image in gridview
Save the uploaded image to folder and insert the path into database. On button click write the below given code:
C# Code:
protected void Button1_Click(object sender, EventArgs e)
    {
        string filepath = Server.MapPath("~/img/") + Guid.NewGuid() + FileUpload1.PostedFile.FileName;
        FileUpload1.SaveAs(filepath);
        string fl = filepath.Substring(filepath.LastIndexOf("\\"));
        string[] split = fl.Split('\\');
        string newpath = split[1];
        string imagepath = "~/img/" + newpath;
        con.Open();
        SqlCommand cmd = new SqlCommand("Sp_InsertPhoto", con);
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@albumid", Convert.ToInt32(Session["albumid"].ToString()));
        cmd.Parameters.AddWithValue("@photopath", newpath);
        cmd.Parameters.Add("@id", SqlDbType.Int);
        cmd.Parameters["@id"].Direction = ParameterDirection.Output;
        cmd.ExecuteNonQuery();
        id = (int)cmd.Parameters["@id"].Value;
        BindGrid();
    }

VB.net Code:
Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click
        Dim filepath As String = Server.MapPath("~/img/") + Guid.NewGuid().ToString() + FileUpload1.PostedFile.FileName
        FileUpload1.SaveAs(filepath)
        Dim fl As String = filepath.Substring(filepath.LastIndexOf("\"))
        Dim split As String() = fl.Split("\"c)
        Dim newpath As String = split(1)
        Dim imagepath As String = Convert.ToString("~/img/") & newpath
        con.Open()
        Dim cmd As New SqlCommand("Sp_InsertPhoto", con)
        cmd.CommandType = CommandType.StoredProcedure
        cmd.Parameters.AddWithValue("@albumid", Convert.ToInt32(Session("albumid").ToString()))
        cmd.Parameters.AddWithValue("@photopath", newpath)
        cmd.Parameters.Add("@id", SqlDbType.Int)
        cmd.Parameters("@id").Direction = ParameterDirection.Output
        cmd.ExecuteNonQuery()
        id = CInt(cmd.Parameters("@id").Value)
        BindGrid()
    End Sub

Bind the Gridview
Create a method to get the last inserted record from database to enter description
C# Code:
public void BindGrid()
    {
        SqlDataAdapter adp = new SqlDataAdapter("Sp_GetPhotoData", con);
        adp.SelectCommand.CommandType = CommandType.StoredProcedure;
        adp.SelectCommand.Parameters.AddWithValue("@id", id);
        DataTable dt = new DataTable();
        adp.Fill(dt);
        grdphoto.DataSource = dt;
        grdphoto.DataBind();    
        btnsave.Visible = true;
    }

VB.net Code:
Public Sub BindGrid()
        Dim adp As New SqlDataAdapter("Sp_GetPhotoData", con)
        adp.SelectCommand.CommandType = CommandType.StoredProcedure
        adp.SelectCommand.Parameters.AddWithValue("@id", id)
        Dim dt As New DataTable()
        adp.Fill(dt)
        grdphoto.DataSource = dt
        grdphoto.DataBind()
        btnsave.Visible = True
    End Sub

Updating the data
Enter the description for image and write the below given code on save button click:
C# Code:
protected void btnsave_Click1(object sender, EventArgs e)
    {
        foreach (GridViewRow gvrow in grdphoto.Rows)
        {
            int id = Convert.ToInt32(grdphoto.DataKeys[gvrow.RowIndex].Value.ToString());
            string name = ((TextBox)gvrow.FindControl("TextBox1")).Text;
            SqlCommand cmd = new SqlCommand("Sp_UpdatePhoto", con);
            cmd.CommandType = CommandType.StoredProcedure;
            con.Open();
            cmd.Parameters.AddWithValue("@PhotoName", name);
            cmd.Parameters.AddWithValue("@id", id);
            cmd.ExecuteNonQuery();
            con.Close();
            grdphoto.DataSource = null;
            grdphoto.DataBind();
        }
     }

VB.net Code:
Protected Sub btnsave_Click(sender As Object, e As System.EventArgs) Handles btnsave.Click
        For Each gvrow As GridViewRow In grdphoto.Rows
            Dim id As Integer = Convert.ToInt32(grdphoto.DataKeys(gvrow.RowIndex).Value.ToString())
            Dim name As String = DirectCast(gvrow.FindControl("TextBox1"), TextBox).Text
            Dim cmd As New SqlCommand("Sp_UpdatePhoto", con)
            cmd.CommandType = CommandType.StoredProcedure
            con.Open()
            cmd.Parameters.AddWithValue("@PhotoName", name)
            cmd.Parameters.AddWithValue("@id", id)
            cmd.ExecuteNonQuery()
            con.Close()
            grdphoto.DataSource = Nothing
            grdphoto.DataBind()
        Next
    End Sub

Redirect to Create new album and view gallery
C# Code:
protected void btngallery_Click(object sender, EventArgs e)
    {
        Response.Redirect("gallery.aspx");
    }
    protected void btncreate_Click(object sender, EventArgs e)
    {
        Response.Redirect("frmAlbum.aspx");
    }

VB.net Code:
Protected Sub btngallery_Click(sender As Object, e As System.EventArgs) Handles btngallery.Click
        Response.Redirect("gallery.aspx")
    End Sub

    Protected Sub btncreate_Click(sender As Object, e As System.EventArgs) Handles btncreate.Click
        Response.Redirect("frmalbumvb.aspx")
    End Sub
