Delete Document Library in SharePoint 2010 Programmatically Using VS 2010

Introduction

 

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

Question: What is a document library?

 

In simple terms "A document library is a location on a site where you can create, collect, update, and manage files with team members. Each library displays a list of files and key information about the files, which helps people to use the files to work together".

 

I think we are now good to go and implement this wonderful concept.

 

Step 1: Create a custom list and modify the view.

 

Step 2: Open SharePoint 2010 Central Administration and navigate to a specific site.

 

Step 3: Open up Visual Studio 2010 and create an "Empty SharePoint project":

 

 

 Step 4: Select "Deploy as a farm solution" and click on the "Finish" button. Now an empty project will be created:

 

 

 

Step 5: Add a new visual webpart for that project.

 

Step 6: The complete code of visualwebpart1usercontrol.ascx looks like this:

 

<%@ Assembly Name="$SharePoint.Project.AssemblyFullName$" %>

<%@ Assembly Name="Microsoft.Web.CommandUI, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

<%@ Register TagPrefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls"

<%@ Import Namespace="Microsoft.SharePoint" %>

<%@ Register TagPrefix="WebPartPages" Namespace="Microsoft.SharePoint.WebPartPages"

    Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

<%@  Control Language="C#" AutoEventWireup="true" CodeBehind="DeleteWebPartUserControl.ascx.cs"

    Inherits="DocumentLibDelete.DeleteWebPart.DeleteWebPartUserControl" %>

<div style="text-align: center;">

    <table style="font-family: Verdana">

        <tr>

            <td colspan="2">

                <asp:label id="Label1" runat="server" text="Document Library Deletion - SharePoint 2010 via Visual Studio"

                    font-bold="true" forecolor="Maroon" font-size="Large"></asp:label>

            </td>

        </tr>

        <tr>

            <td>

                <asp:label id="Label2" runat="server" text="Please Enter Document Library Name:"></asp:label>

            </td>

            <td>

                <asp:textbox id="TextBox1" runat="server"></asp:textbox>

            </td>

        </tr>

        <tr>

            <td>

                <asp:label id="Label3" runat="server" text="Please Enter Document Library ID:"></asp:label>

            </td>

            <td>

                <asp:textbox id="TextBox2" runat="server"></asp:textbox>

            </td>

        </tr>

        <tr>

            <td colspan="2">

                <asp:button id="Button1" runat="server" text="Delete" forecolor="Orange" font-bold="true"

                    backcolor="Black" onclick="Button1_Click" width="116px" />

            </td>

        </tr>

        <tr>

            <td colspan="2">

                <asp:label id="Label4" runat="server" font-bold="true"></asp:label>

            </td>

        </tr>

    </table>

</div>

Step 7: The complete code of visualwebpart1usercontrol.ascx.cs looks like this:
 

using System;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using Microsoft.SharePoint;

namespace DocumentLibDelete.DeleteWebPart

{

    public partial class DeleteWebPartUserControl : UserControl

    {

        protected void Page_Load(object sender, EventArgs e)

        {

            TextBox1.Focus();

        }

        protected void Button1_Click(object sender, EventArgs e)

        {

            if (string.IsNullOrEmpty(TextBox1.Text) || string.IsNullOrEmpty(TextBox2.Text))

            {

                Label4.Text = "Please Enter Name and ID to Delete";

                Label4.ForeColor = System.Drawing.Color.Red;

            }

            else

            {

                SPSite site = SPContext.Current.Site;

                SPWeb web = site.OpenWeb() as SPWeb;

                web.AllowUnsafeUpdates = true;

                SPList listdoc = web.Lists[TextBox1.Text];

                SPListItem item = listdoc.GetItemById(Convert.ToInt32(TextBox2.Text));

                listdoc.OnQuickLaunch = true;

                item.Delete();

                web.AllowUnsafeUpdates = false; web.Dispose();

                web.Dispose();

                Label4.ForeColor = System.Drawing.Color.Green;

                Label4.Text = TextBox2.Text + "'item in " + TextBox1.Text + " Document Library is deleted successfully";

                TextBox1.Text = string.Empty;

                TextBox2.Text = string.Empty;

            }

        }

    }

}

 

Step 8: Deploy the solution file and add the created webpart to a SharePoint site.

 

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

 

 

 

 

 Step 10: Document library entering output of the application looks like this:

 

 

 

 

Step 11: Document library file deleted output of the application looks like this:
