Introduction

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

Question: What is creating a list via COM?

In simple terms "To create a new list template using the client object model".

Step 1: Open Visual Studio 2010 and select web forms application

Now two references need to be added to the application, they are:

  • Microsoft.SharePoint.Client

  • Microsoft.SharePoint.Client.Runtime

Step 2: The complete code of webform1.aspx looks like this:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="CreateListCOMApp._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 style="text-align: center">

<tr>

<td colspan="2">

<asp:Label ID="Label1" runat="server" Text="Client Object Model List Creation - SharePoint 2010 Programatically"

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

</td>

</tr>

<tr>

<td>

<asp:Label ID="Label4" runat="server" Text="Please Enter List Name" Font-Size="Large"

Font-Names="Verdana" Font-Italic="true"></asp:Label>

</td>

<td>

<asp:TextBox ID="TextBox4" runat="server" Width="117px"></asp:TextBox>

</td>

</tr>

<tr>

<td colspan="2">

<br />

<asp:Button ID="Button1" runat="server" Text="Create List" 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>

</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;

using Microsoft.SharePoint.Client;

namespace CreateListCOMApp

{

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

{

protected void Page_Load(object sender, EventArgs e)

{

TextBox4.Focus();

}

protected void Button1_Click(object sender, EventArgs e)

{

if (string.IsNullOrEmpty(TextBox4.Text))

{

Label5.Text = "Please Enter Some Values";

Label5.ForeColor = System.Drawing.Color.Red;

}

else

{

ClientContext objContext = new ClientContext("http://win-kv3bo1rqqf7:25339/");

Web objWeb = objContext.Web; ListCreationInformation createInfo = new ListCreationInformation();

createInfo.Title = TextBox4.Text;

createInfo.TemplateType = (int)ListTemplateType.CustomGrid;

List objList = objWeb.Lists.Add(createInfo);

objList.OnQuickLaunch = true; objList.Update(); objContext.ExecuteQuery();

Label5.Text = "List Created Successfully";

Label5.ForeColor = System.Drawing.Color.Green;

TextBox4.Text = string.Empty;

}

}

}

}

Step 4: The output of the application looks like this:

Step 5: Data entering output of the application looks like this:

creation-client-object-model-list-sharepoint2010.jpg

Step 6: The output of the field created SharePoint application looks like this:
