Introduction Today, in this article let's play around with one of the interesting and most useful concepts in SharePoint 2010. Question: What is a SPMetal LINQ to SharePoint Insert? In simple terms "It enables creation of a DataContext object using SPMetal, by which we can insert the data to a custom list with the help of a LINQ query". I think we are now good to go and implement this wonderful concept. Step 1 : Open the command prompt as an administrator and enter the following command by requesting a specific site: Spmetal.exe /web:http://win-5d57sl2rvt1:9107/ /code:C:\Student.cs After you have run this, the Student.cs file will be created in the C: Drive of your system directories. Step 2 : Open SharePoint 2010 Central Administration and navigate to a specific site. Step 3 : Open up Visual Studio 2010 and try to create an empty SharePoint project. Step 4 : Select "Deploy as a farm solution" and click the next button. Now an empty project will be created. Step 5 : Add a new visual webpart for that project. Also add the Student.cs file into the project. Step 6 : The complete code of visualwebpart1usercontrol.ascx looks like this: <%@ Assembly Name="$SharePoint.Project.AssemblyFullName$" %> <%@ Assembly Name="Microsoft.Web.CommandUI, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %> <%@ Register TagPrefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %> <%@ Register TagPrefix="Utilities" Namespace="Microsoft.SharePoint.Utilities" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %> <%@ Register TagPrefix="asp" Namespace="System.Web.UI" Assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" %> <%@ Import Namespace="Microsoft.SharePoint" %> <%@ Register TagPrefix="WebPartPages" Namespace="Microsoft.SharePoint.WebPartPages" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %> <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="SPMetalInsertWPUserControl.ascx.cs" Inherits="SPMetalInsertApp.SPMetalInsertWP.SPMetalInsertWPUserControl" %> <center> <div> <table> <tr> <td colspan="2"> <asp:label id="Label1" runat="server" text="LINQ-TO-SharePoint Insertion - SharePoint 2010 Programatically" font-bold="true" font-size="Large" font-names="Verdana" forecolor="Maroon"></asp:label> </td> </tr> <tr> <td> <asp:label id="Label2" runat="server" text="Please Enter First Name" font-size="Large" font-names="Verdana" font-italic="true"></asp:label> </td> <td> <asp:textbox id="TextBox1" runat="server" width="117px"></asp:textbox> </td> </tr> <tr> <td> <asp:label id="Label3" runat="server" text="Please Enter Last Name" font-size="Large" font-names="Verdana" font-italic="true"></asp:label> </td> <td> <asp:textbox id="TextBox2" runat="server" width="117px"></asp:textbox> </td> </tr> <tr> <td> <asp:label id="Label4" runat="server" text="Please Enter Gender" font-size="Large" font-names="Verdana" font-italic="true"></asp:label> </td> <td> <asp:dropdownlist id="DropDownList1" runat="server" style="margin-left: 0px" width="117px"><asp:ListItem Text="Male" Value="1"></asp:ListItem><asp:ListItem Text="Female" Value="2"></asp:ListItem></asp:dropdownlist> </td> </tr> <tr> <td> <asp:label id="Label6" runat="server" text="Please Enter Age" font-size="Large" font-names="Verdana" font-italic="true"></asp:label> </td> <td> <asp:textbox id="TextBox3" runat="server" width="117px"></asp:textbox> </td> </tr> <tr> <td colspan="2"> <br /> <asp:button id="Button1" runat="server" text="Insert Data" font-names="Verdana" width="282px" backcolor="Orange" font-bold="True" onclick="Button1_Click" /> </td> </tr> <tr> <td colspan="2"> <br /> <asp:label id="Label5" runat="server" font-bold="true" font-names="Verdana"></asp:label> </td> </tr> </table> </div> </center> Step 7 : The complete code of visualwebpart1usercontrol.ascx.cs looks like this: using System; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using Microsoft.SharePoint.Linq; using WebApplication2; namespace SPMetalInsertApp.SPMetalInsertWP { public partial class SPMetalInsertWPUserControl : UserControl { protected void Page_Load(object sender, EventArgs e) { TextBox1.Focus(); } 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 { StudentDataContext dataContext = new StudentDataContext("http://win-5d57sl2rvt1:9107/"); EntityList<PersonListItem> listItems = dataContext.GetList<PersonListItem>("PersonList"); PersonListItem item = new PersonListItem() { Title = TextBox1.Text, LastName = TextBox2.Text, Gender = DropDownList1.SelectedItem.Text, Age = int.Parse(TextBox3.Text), }; listItems.InsertOnSubmit(item); dataContext.SubmitChanges(); Label5.Text = "Data Successfully Inserted"; Label5.ForeColor = System.Drawing.Color.Green; TextBox1.Text = string.Empty; TextBox2.Text = string.Empty; TextBox3.Text = string.Empty; } } } } Step 8 : Deploy the solution file and add the created webpart to the SharePoint site. Step 9 : The output of the person list looks like this: Step 10 : The output of the application looks like this: Step 11 : The output of the data inserting application looks like this: Step 12 : The output of the data inserted in person list looks like this: I hope this article is useful for you.. I look forward for your comments and feedback.. Thanks Vijay Prativadi
