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"

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

<%@ Register TagPrefix="Utilities" Namespace="Microsoft.SharePoint.Utilities" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

<%@ Register TagPrefix="asp" Namespace="System.Web.UI" Assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" %>

<%@ 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:
