Introduction

Today, in this article let's play around with one of the interesting and most useful concepts in SharePoint 2010.

Question: What is select list data with wcf service?
 

In simple terms "It enables to select data from SharePoint custom list using a client side environment via WCF service".

Step 1: Open SharePoint 2010 Central Administration and navigate to a specific site.

Step 2: Open up Visual Studio 2012 and create an "ASP.NET Web Forms Application", as in:

Step 3: Remove the following reference for the project:

 

System.Data.Services.Client

 

Step 4: Replace with a new reference for the project. (For this you need to install ADO.NET Data Services.exe file from here.)

 

After installation, browse to the specific location at:

 

C:\Program Files (x86)\ADO.NET Data Services V1.5 CTP2\bin

 

Add this reference to the project: Microsoft.Data.Services.Client.dll

 

Step 5: Add the service reference to the project. This should come up from the following link. (So here the site URL is http://win-5c3g1lanj3k:29782/ . This might be differerent based on your custom site URL. Another part is _vti_bin/ListData.svc that should be common to access the service reference for any site.)

 

http://win-5c3g1lanj3k:29782/_vti_bin/ListData.svc

 

Step 6: The complete code of WebForm1.aspx looks like this:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="SelectListDataWCFDataServiceApp._Default" %>

 

<!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">

    <center>

        <div>

            <table>

                <tr>

                    <td colspan="2">

                        <asp:Label ID="Label1" runat="server" Text="Select List Data - WCF Data  in SharePoint 2010 using VS 2012 "

                            Font-Bold="true" Font-Size="Large" Font-Names="Verdana" ForeColor="Maroon"></asp:Label>

                    </td>

                </tr>

                <tr>

                    <td colspan="2" align="center">

                        <asp:Button ID="Button2" runat="server" Text="Select List Data" Font-Names="Verdana"

                            Width="166px" BackColor="Orange" Font-Bold="True" OnClick="Button2_Click" /><br />

                        <br />

                    </td>

                </tr>

                <tr>

                    <td colspan="2" align="center">

                        <asp:GridView ID="GridView1" runat="server" BackColor="LightGoldenrodYellow" BorderColor="Tan"

                            BorderWidth="1px" CellPadding="2" EnableModelValidation="True" ForeColor="Black"

                            GridLines="None" AutoGenerateColumns="False">

                            <AlternatingRowStyle BackColor="PaleGoldenrod"></AlternatingRowStyle>

                            <FooterStyle BackColor="Tan"></FooterStyle>

                            <HeaderStyle BackColor="Tan" Font-Bold="True"></HeaderStyle>

                            <PagerStyle HorizontalAlign="Center" BackColor="PaleGoldenrod" ForeColor="DarkSlateBlue">

                            </PagerStyle>

                            <SelectedRowStyle BackColor="DarkSlateBlue" ForeColor="GhostWhite"></SelectedRowStyle>

                            <Columns>

                                <asp:BoundField DataField="ID" HeaderText="Student Id" ReadOnly="true" SortExpression="Id" />

                                <asp:BoundField DataField="FirstName" HeaderText="First Name" ReadOnly="true" />

                                <asp:BoundField DataField="LastName" HeaderText="Last Name" ReadOnly="true" />

                                <asp:BoundField DataField="Age" HeaderText="Age" ReadOnly="true" />

                            </Columns>

                        </asp:GridView>

                    </td>

                </tr>

                <tr>

                    <td colspan="2" align="center">

                        <asp:Label ID="Label5" runat="server" Font-Bold="true" Font-Names="Verdana" ForeColor="Maroon"></asp:Label>

                    </td>

                </tr>

            </table>

        </div>

    </center>

    </form>

</body>

</html>

 

Step 7: 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;

using SelectListDataWCFDataServiceApp.ServiceReference1;

namespace SelectListDataWCFDataServiceApp

{

    public partial class _Default : System.Web.UI.Page

    {

        protected void Page_Load(object sender, EventArgs e)

        {

        }

        protected void Button2_Click(object sender, EventArgs e)

        {

            MainSiteDataContext objContext = new MainSiteDataContext(new Uri("http://win-5c3g1lanj3k:29782/_vti_bin/ListData.svc"));

            objContext.Credentials = System.Net.CredentialCache.DefaultCredentials;

            GridView1.DataSource = objContext.Students.ToList();

            GridView1.DataBind();

        }

    }

}

 

Step 8: The output of the application looks like this:

Step 9: The select data output of the application looks like this:
