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:
![asp.net-web-form-application.jpg]()
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:
![select-list-data-sharepoint2010.jpg]()
Step 9: The select data output of the application looks like this:
![wcf-select-list-data-sharepoint2010.jpg]()
