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

 

Question: What is ClientOMDelete?

 

In simple terms "To delete the data from client side environment for SharePoint applications, this is used".

 

Step 1: Open Visual Studio 2012 and select "ASP.Net Web Forms Application", as in:

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="WebForm1.aspx.cs" Inherits="ClientOMDeletion.WebForm1" %>
 
<!DOCTYPE html>
<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 Deletion - 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>
                        <asp:Label ID="Label7" runat="server" Text="Please Enter ID" Font-Size="Large" Font-Names="Verdana"
                            Font-Italic="true"></asp:Label>
                    </td>
                    <td>
                        <asp:TextBox ID="TextBox5" runat="server" Width="117px"></asp:TextBox>
                    </td>
                </tr>
                <tr>
                    <td colspan="2">
                        <br />
                        <asp:Button ID="Button1" runat="server" Text="Delete 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>
    </form>
</body>
</
html>

 

 Step 3: The complete code of webform1.aspx.cs looks like this:

using Microsoft.SharePoint.Client;

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

namespace ClientOMDeletion

{

    public partial class WebForm1 : 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) || string.IsNullOrEmpty(TextBox5.Text))

            {

                Label5.Text = "Please Enter Some Values";

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

            }

            else

            {

                ClientContext objContext = new ClientContext("http://win-5c3g1lanj3k:46908/");

                List list = objContext.Web.Lists.GetByTitle(TextBox4.Text);

                Microsoft.SharePoint.Client.ListItem item = list.GetItemById(TextBox5.Text);

                item.DeleteObject();

                objContext.ExecuteQuery();

                Label5.Text = "Data deleted Successfully";

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

                TextBox4.Text = string.Empty;

                TextBox5.Text = string.Empty;

            }

        }

    }

}

 

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

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

Step 6: The output of the list on SharePoint application looks like this:
