Select, Edit, update and Delete in Gridview with store procedure using Linq

In this article I will explain how to Select, Edit, update and Delete in Gridview with store procedure using Linq

Description:

I have created a table Tb_Student and having records. To display, Update and Delete the students detail in Gridview create store procedures.

Implementation:
First of all I have created Store Procedures to Get, Update and Delete.

Store Procedure to get data:-
CREATE Proc Sp_GetStudentData 
As begin
Select * from dbo.Tb_Student
end

Store Procedure to Update data:-
Create Proc Sp_UpdateStudents
(
@id int,
@sname varchar(50),
@saddress varchar(200),
@rollno          int
)
As begin
Update Tb_Student set Student_Name=@sname,Student_Address=@saddress,RollNo=@rollno where id =@id
end

Store Procedure to Delete data:-
CREATE Proc Sp_DeleteStudents
(
@id int
)
As begin
Delete from Tb_Student where id =@id
end

Now drag and drop the Gridview control from toolbox to webform.
Gridview markup:
<asp:GridView ID="grdstudent" runat="server" AutoGenerateColumns="false" AllowPaging="true" PageSize="4" DataKeyNames="Id" CellPadding="4" ForeColor="#333333" GridLines="None">
          <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
            <Columns>
               <asp:TemplateField HeaderText="Name">
                   <ItemTemplate>
                       <asp:Label ID="lblname" runat="server" Text='<%# Eval("Student_Name") %>'></asp:Label>
                   </ItemTemplate>
                   <EditItemTemplate>
                       <asp:TextBox ID="txtname" runat="server" Text='<%# Eval("Student_Name") %>'></asp:TextBox>
                   </EditItemTemplate>
               </asp:TemplateField>
                  <asp:TemplateField HeaderText="City/State">
                   <ItemTemplate>
                        <asp:Label ID="lbladdress" runat="server" Text='<%# Eval("Student_Address") %>'></asp:Label>
                   </ItemTemplate>
                   <EditItemTemplate>
                       <asp:TextBox ID="txtaddress" runat="server" Text='<%# Eval("Student_Address") %>'></asp:TextBox>
                   </EditItemTemplate>
               </asp:TemplateField>
                  <asp:TemplateField HeaderText="Roll No.">
                   <ItemTemplate>
                        <asp:Label ID="lblrollno" runat="server" Text='<%# Eval("RollNo") %>'></asp:Label>
                   </ItemTemplate>
                   <EditItemTemplate>
                       <asp:TextBox ID="txtrollno" runat="server" Text='<%# Eval("RollNo") %>'></asp:TextBox>
                   </EditItemTemplate>
               </asp:TemplateField>
                <asp:CommandField ShowEditButton="True" />
                <asp:CommandField ShowDeleteButton="True" />
            </Columns>
            <EditRowStyle BackColor="#999999" />
            <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
            <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
            <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
            <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
            <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
            <SortedAscendingCellStyle BackColor="#E9E7E2" />
            <SortedAscendingHeaderStyle BackColor="#506C8C" />
            <SortedDescendingCellStyle BackColor="#FFFDF8" />
            <SortedDescendingHeaderStyle BackColor="#6F8DAE" />
        </asp:GridView>

Create object of dataContext
C#:
ProjectDataClassesDataContext db = new ProjectDataClassesDataContext();

VB:
Dim db As New ProjectDataClassesDataContext

Code to populate the gridview
C#:
protected void Page_Load(object sender, EventArgs e)
    {
        if(!IsPostBack)
        {
            BindGrid();
        }
    }
public void BindGrid()
    {
        grdstudent.DataSource = db.Sp_GetStudentData();
        grdstudent.DataBind();
    }

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()
        grdstudent.DataSource = db.Sp_GetStudentData
        grdstudent.DataBind()
    End Sub

PageIndex event of Gridview for paging
C#:
  protected void grdstudent_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        grdstudent.PageIndex = e.NewPageIndex;
        BindGrid();
    }

VB:
Protected Sub grdstudent_PageIndexChanging(sender As Object, e As GridViewPageEventArgs) Handles grdstudent.PageIndexChanging
        grdstudent.PageIndex = e.NewPageIndex
        BindGrid()
    End Sub

Enable the editing mode of Gridview record
C#:
  protected void grdstudent_RowEditing(object sender, GridViewEditEventArgs e)
    {
        grdstudent.EditIndex = e.NewEditIndex;
        BindGrid();
    }

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

Update the Record
Write the code on RowUpdating event of Gridview
C#:
protected void grdstudent_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        try
        {
            int id = Convert.ToInt32(grdstudent.DataKeys[e.RowIndex].Value);
            TextBox txtname = (TextBox)grdstudent.Rows[e.RowIndex].FindControl("txtname");
            TextBox txtaddress = (TextBox)grdstudent.Rows[e.RowIndex].FindControl("txtaddress");
            TextBox txtrollno = (TextBox)grdstudent.Rows[e.RowIndex].FindControl("txtrollno");
            db.Sp_UpdateStudents(id, txtname.Text, txtaddress.Text, Convert.ToInt32(txtrollno.Text));
            db.SubmitChanges();
            grdstudent.EditIndex = -1;
            BindGrid();
            Response.Write("<script type=\"text/javascript\">alert('Record has been Updated Successfully');</script>");
        }
        catch(Exception ex)
        {
        }
    }

VB:
Protected Sub grdstudent_RowUpdating(sender As Object, e As GridViewUpdateEventArgs) Handles grdstudent.RowUpdating
        Try
            Dim id As Integer = Convert.ToInt32(grdstudent.DataKeys(e.RowIndex).Value)
            Dim txtname As TextBox = DirectCast(grdstudent.Rows(e.RowIndex).FindControl("txtname"), TextBox)
            Dim txtaddress As TextBox = DirectCast(grdstudent.Rows(e.RowIndex).FindControl("txtaddress"), TextBox)
            Dim txtrollno As TextBox = DirectCast(grdstudent.Rows(e.RowIndex).FindControl("txtrollno"), TextBox)
            db.Sp_UpdateStudents(id, txtname.Text, txtaddress.Text, Convert.ToInt32(txtrollno.Text))
            db.SubmitChanges()
            grdstudent.EditIndex = -1
            BindGrid()
            Response.Write("<script type=""text/javascript"">alert('Record has been updated successfully');</script>")
        Catch ex As Exception
        End Try
    End Sub

Cancel the editing record
Write the code on RowCancelingEdit event of gridview
C#:
  protected void grdstudent_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
    {
        grdstudent.EditIndex = -1;
        BindGrid();
    }

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

Delete the record
To delete the record write the given code on RowDeleting event of gridview.
C#:
protected void grdstudent_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        try
        {
            int id = Convert.ToInt32(grdstudent.DataKeys[e.RowIndex].Value);
            db.Sp_DeleteStudents(id);
            db.SubmitChanges();
            BindGrid();
            Response.Write("<script type=\"text/javascript\">alert('Record has been Deleted Successfully');</script>");
        }
        catch(Exception ex)
        {

        }
    }

VB:
Protected Sub grdstudent_RowDeleting(sender As Object, e As GridViewDeleteEventArgs) Handles grdstudent.RowDeleting
        Try
            Dim id As Integer = Convert.ToInt32(grdstudent.DataKeys(e.RowIndex).Value)
            db.Sp_DeleteStudents(id)
            db.SubmitChanges()
            BindGrid()
            Response.Write("<script type=""text/javascript"">alert('Record has been Deleted successfully');</script>")
        Catch ex As Exception
        End Try
    End Sub

Now build, run the project/website and check the result.
