ADO.Net entity framework CRUD function using store procedure in Gridview

In this article I am going to share how we can do CRUD (Create, Read, Update and Delete) operations in Gridview using ADO.Net Entity Framework

Description:

Create a table movie. I am going to insert, edit, update and delete the record into table using  Gridview.
ADO.Net entity framework CRUD function using store procedure in Gridview


Implementation:
First of all create store procedure to Insert, update, Select and delete the record.

Store Procedure to Insert Record
Create PROCEDURE Sp_InsertMovieDetail
(
@name varchar(100),
@genre varchar(100),
@cost int,
@poster varchar(max)
)
AS
BEGIN
            SET NOCOUNT ON;
Insert into Movie(Name,Genre,Cost,Poster) values(@name,@genre,@cost,@poster)
END

Store Procedure to Update Record
Create PROCEDURE Sp_UpdateMovieDetail
(
@id int,
@name varchar(100),
@genre varchar(100),
@cost int
)
AS
BEGIN
            SET NOCOUNT ON;
Update Movie set Name=@name,Genre=@genre,Cost=@cost where Id =@id
END

Store Procedure to select record
Create Proc Sp_GetMovieData
as
begin
Select * from Movie
End

Store Procedure to Delete Record
Create PROCEDURE Sp_DeleteMovieRecord
(
@id int
)
AS
BEGIN
            SET NOCOUNT ON;
Delete from Movie where Id =@id
END

Add webform to project/website. Drag and drop the Gridview control from toolbox to webform.

HTML Markup of Gridview:

Instantiate the Entity dbcontext
C#:
DemoEntities db = new DemoEntities();

VB:
Private db As New DemoEntities()

Create a function to fetch the record and bind to gridview and call it on page load event.
C#:
   protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            BindGrid();
        }
    }
    public void BindGrid()
    {
        try
        {
            grdmovie.DataSource = db.Sp_GetMovieData();
            grdmovie.DataBind();
        }
        catch (Exception ex)
        { }
    }  

VB:
Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
        If Not IsPostBack Then
            BindGrid()
        End If
    End Sub
    Public Sub BindGrid()
        Try
            grdmovie.DataSource = db.Sp_GetMovieData()
            grdmovie.DataBind()
        Catch ex As Exception
        End Try
    End Sub

Edit the record
C#:
protected void grdmovie_RowEditing(object sender, GridViewEditEventArgs e)
    {
        grdmovie.EditIndex = e.NewEditIndex;
        BindGrid();
    }

VB:
  Protected Sub grdmovie_RowEditing(sender As Object, e As GridViewEditEventArgs) Handles grdmovie.RowEditing
        grdmovie.EditIndex = e.NewEditIndex
        BindGrid()
    End Sub

Write the code on RowCommand event of Gridview to Insert, Update and delete the record.
C#:
protected void grdmovie_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "Insert")
        {
            TextBox txtname = (TextBox)grdmovie.FooterRow.FindControl("txtname");
            TextBox txtgenre = (TextBox)grdmovie.FooterRow.FindControl("txtgenre");
            TextBox txtcost = (TextBox)grdmovie.FooterRow.FindControl("txtcost");
            FileUpload fileupload = (FileUpload)grdmovie.FooterRow.FindControl("FileUpload1");
            string filepath = Server.MapPath("~/images/") + Guid.NewGuid() + fileupload.PostedFile.FileName;
            fileupload.SaveAs(filepath);
            string fl = filepath.Substring(filepath.LastIndexOf("\\"));
            string[] split = fl.Split('\\');
            string newpath = split[1];
            string imagepath = "~/images/" + newpath;
            db.Sp_InsertMovieDetail(txtname.Text, txtgenre.Text, Convert.ToInt32(txtcost.Text), imagepath);
            Response.Write("<script>alert('Record Insert Successfully');</script>");
            txtname.Text = string.Empty;
            txtcost.Text = string.Empty;
            txtgenre.Text = string.Empty;
            BindGrid();
        }
        if (e.CommandName == "Delete")
        {
            ImageButton imgbtn = (ImageButton)e.CommandSource;
            GridViewRow gvrow = ((GridViewRow)imgbtn.NamingContainer);
            int id = Convert.ToInt32(grdmovie.DataKeys[gvrow.RowIndex].Value);
            Movie objtb = new Movie();
            db.Sp_DeleteMovieRecord(id);           
            db.SaveChanges();
            BindGrid();
            Response.Write("<script>alert('Record Deleted Successfully');</script>");
        }
        if (e.CommandName == "Update")
        {
            ImageButton imgbtn = (ImageButton)e.CommandSource;
            GridViewRow gvrow = ((GridViewRow)imgbtn.NamingContainer);
            int id = Convert.ToInt32(grdmovie.DataKeys[gvrow.RowIndex].Value.ToString());
            TextBox txtname = (TextBox)grdmovie.Rows[gvrow.RowIndex].FindControl("txtname");
            TextBox txtgenre = (TextBox)grdmovie.Rows[gvrow.RowIndex].FindControl("txtgenre");
            TextBox txtcost = (TextBox)grdmovie.Rows[gvrow.RowIndex].FindControl("txtcost");
            db.Sp_UpdateMovieDetail(id,txtname.Text, txtgenre.Text, Convert.ToInt32(txtcost.Text));
            db.SaveChanges();           
            grdmovie.EditIndex = -1;
            BindGrid();
            Response.Write("<script>alert('Record Deleted Successfully');</script>");
        }
    }
protected void grdmovie_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
      
    }  
    protected void grdmovie_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {

    }

VB:
Protected Sub grdmovie_RowCommand(sender As Object, e As GridViewCommandEventArgs) Handles grdmovie.RowCommand
        If e.CommandName = "Insert" Then
            Dim txtname As TextBox = DirectCast(grdmovie.FooterRow.FindControl("txtname"), TextBox)
            Dim txtgenre As TextBox = DirectCast(grdmovie.FooterRow.FindControl("txtgenre"), TextBox)
            Dim txtcost As TextBox = DirectCast(grdmovie.FooterRow.FindControl("txtcost"), TextBox)
            Dim fileupload As FileUpload = DirectCast(grdmovie.FooterRow.FindControl("FileUpload1"), FileUpload)
            Dim filepath As String = Server.MapPath("~/images/") & Guid.NewGuid().ToString() & fileupload.PostedFile.FileName
            fileupload.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("~/images/") & newpath
            db.Sp_InsertMovieDetail(txtname.Text, txtgenre.Text, Convert.ToInt32(txtcost.Text), imagepath)
            Response.Write("<script>alert('Record Insert Successfully');</script>")
            txtname.Text = String.Empty
            txtcost.Text = String.Empty
            txtgenre.Text = String.Empty
            BindGrid()
        End If
        If e.CommandName = "Delete" Then
            Dim imgbtn As ImageButton = DirectCast(e.CommandSource, ImageButton)
            Dim gvrow As GridViewRow = DirectCast(imgbtn.NamingContainer, GridViewRow)
            Dim id As Integer = Convert.ToInt32(grdmovie.DataKeys(gvrow.RowIndex).Value)
            Dim objtb As New Movie()
            db.Sp_DeleteMovieRecord(id)
            db.SaveChanges()
            BindGrid()
            Response.Write("<script>alert('Record Deleted Successfully');</script>")
        End If
        If e.CommandName = "Update" Then
            Dim imgbtn As ImageButton = DirectCast(e.CommandSource, ImageButton)
            Dim gvrow As GridViewRow = DirectCast(imgbtn.NamingContainer, GridViewRow)
            Dim id As Integer = Convert.ToInt32(grdmovie.DataKeys(gvrow.RowIndex).Value.ToString())
            Dim txtname As TextBox = DirectCast(grdmovie.Rows(gvrow.RowIndex).FindControl("txtname"), TextBox)
            Dim txtgenre As TextBox = DirectCast(grdmovie.Rows(gvrow.RowIndex).FindControl("txtgenre"), TextBox)
            Dim txtcost As TextBox = DirectCast(grdmovie.Rows(gvrow.RowIndex).FindControl("txtcost"), TextBox)
            db.Sp_UpdateMovieDetail(id, txtname.Text, txtgenre.Text, Convert.ToInt32(txtcost.Text))
            db.SaveChanges()
            grdmovie.EditIndex = -1
            BindGrid()
            Response.Write("<script>alert('Record Updated Successfully');</script>")
        End If
    End Sub
Protected Sub grdmovie_RowDeleting(sender As Object, e As GridViewDeleteEventArgs) Handles grdmovie.RowDeleting

    End Sub
    Protected Sub grdmovie_RowUpdating(sender As Object, e As GridViewUpdateEventArgs) Handles grdmovie.RowUpdating

    End Sub

Cancel the edit mode
C#:
protected void grdmovie_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
    {
        grdmovie.EditIndex = -1;
        BindGrid();
    }

VB:
Protected Sub grdmovie_RowCancelingEdit(sender As Object, e As GridViewCancelEditEventArgs) Handles grdmovie.RowCancelingEdit
        grdmovie.EditIndex = -1
        BindGrid()
    End Sub

Build the project and run, test it. Hope this helps you.
