Today, in this article let's play around with the Insert and Update concept in LINQ.
Introduction Question: What is insert data with SP using LINQ? In simple terms "It enables insertion of data using a Stored Procedure with LINQ queries". Step 1: Create a new webform project: Step 2: The complete code of webform1.aspx looks like this: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="InsertSPLINQApp.WebForm1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head id="Head1" runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <center> <table> <tr> <td> <asp:Label ID="Label1" runat="server" Text="Insert using SP with LINQ" Font-Bold="true"></asp:Label> </td> </tr> <tr> <td> <asp:GridView ID="GridView1" runat="server" BackColor="#CCCCCC" AutoGenerateColumns="true" BorderColor="#999999" BorderStyle="Solid" BorderWidth="3px" CellPadding="4" CellSpacing="2" ForeColor="Black" OnLoad="Page_Load"> <FooterStyle BackColor="#CCCCCC" /> <HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" /> <PagerStyle BackColor="#CCCCCC" ForeColor="Black" HorizontalAlign="Left" /> <RowStyle BackColor="White" /> <SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" /> <SortedAscendingCellStyle BackColor="#F1F1F1" /> <SortedAscendingHeaderStyle BackColor="#808080" /> <SortedDescendingCellStyle BackColor="#CAC9C9" /> <SortedDescendingHeaderStyle BackColor="#383838" /> </asp:GridView> </td> </tr> </table> <br /> <br /> <table> <tr> <td> <asp:Label ID="Label2" runat="server" Text="Please Enter FirstName: " ForeColor="Brown" Font-Bold="true" Font-Italic="true"></asp:Label> </td> <td> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> </td> </tr> <tr> <td> <asp:Label ID="Label3" runat="server" Text="Please Enter LastName: " ForeColor="Brown" Font-Bold="true" Font-Italic="true"></asp:Label> </td> <td> <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox> </td> </tr> <tr> <td> <asp:Label ID="Label4" runat="server" Text="Please Enter Age: " ForeColor="Brown" Font-Bold="true" Font-Italic="true"></asp:Label> </td> <td> <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox> </td> </tr> <tr> <td colspan="2"> <asp:Button ID="Button1" runat="server" Text="Insert Data" OnClick="Button1_Click" BackColor="Orange" Font-Bold="true" /><br /> <br /> </td> </tr> </table> <br /> <br /> <table> <tr> <td colspan="3"> <asp:Label ID="Label5" runat="server" ForeColor="Red" Font-Bold="true"></asp:Label> </td> </tr> </table> </center> </div> </form> </body> </html> Step 3: The complete code of webform1.aspx.cs looks like this: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace InsertSPLINQApp { public partial class WebForm1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void Button1_Click(object sender, EventArgs e) { if(string.IsNullOrEmpty(TextBox1.Text)||string.IsNullOrEmpty(TextBox2.Text)|| string.IsNullOrEmpty(TextBox3.Text)) { Label5.Text = "Please Enter Some Values"; Label5.ForeColor = System.Drawing.Color.Red; } else { objEntities.InsertEmployeeData(TextBox1.Text, TextBox2.Text, int.Parse(TextBox3.Text)); var query = objEntities.SelectEmpData(); GridView1.DataSource = query; GridView1.DataBind(); Label5.Text = "Records Inserted Successfully"; Label5.ForeColor = System.Drawing.Color.Green; TextBox1.Text = string.Empty; TextBox2.Text = string.Empty; TextBox3.Text = string.Empty; } } #region Instance MembersCompanyEntities1 objEntities = new CompanyEntities1(); #endregion } } Step 4: The output of the application looks like this: Step 5: The output of the data inserted output operation result looks like this: Question: What is update data with SP using LINQ?

I look forward for your comments and feedback. Thanks Vijay Prativadi
