Create List in SharePoint 2010 Programmatically Using VS 2010 Via COM

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.ClientMicrosoft.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;
            }
        }
    }
}
