How to Create Custom Application Page in SharePoint 2010 to get List Owners?

In my environment, This is one of a Frequently asked question: How do I find who has created a List or Library? oops, I don't find any direct way from SharePoint interface to know who has created a List or Library.

Lets develop a Application page, host it under Layouts folder and let the users access that page to get the list owners information.

How to get Who has Created a List/Library?

Here is how to Create a Custom Application Page for SharePoint 2010 using Visual Studio - Step by Step:

1. Create a Visual studio "Empty SharePoint Project", Give it a name, Lets say "ListOwner".

2. Add a New Item to the Project, choose "Application Page", Name it, Say "ListOwner.aspx"

3. This will create the project structure as in the below screen.

4. Now, Lets add a grid to the page, to display all the Lists and its owners from the current site.
Go to the ListOwner.aspx page, locate the code block:

<asp:Content ID="Main" ContentPlaceHolderID="PlaceHolderMain" runat="server">
</asp:Content>

and add the SPGrid in between above code. So it will be:

<asp:Content ID="Main" ContentPlaceHolderID="PlaceHolderMain" runat="server">
<asp:Label ID="Label1" runat="server" Text="Label"><h2>List owners Info:</h2></asp:Label>
     
     <SharePoint:SPGridView runat="server" ID="GridView" AutoGenerateColumns="false"
            GridLines=Horizontal HeaderStyle-BackColor="#18518E" RowStyle-BackColor="#D3E4E5" RowStyle-ForeColor="Black" AlternatingRowStyle-BackColor="#fcfcfc" HeaderStyle-Font-Bold="true"  />
     
</asp:Content>

As the next step, we've to write the code to fetch the lists & libraries to the Grid, by editing ListOwner.aspx.cs

using System;
using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
using System.Data;
using System.Web.UI.WebControls;

namespace ListOwner.Layouts.ListOwner
{
    public partial class ListOwner : LayoutsPageBase
    {
   
        protected void Page_Load(object sender, EventArgs e)
        {
            DataTable dt = new DataTable();
      
            //Add columns to Data Table
            dt.Columns.Add("List Name", typeof(string));
            dt.Columns.Add("List URL", typeof(string));
            dt.Columns.Add("Description", typeof(string));
            dt.Columns.Add("Owner", typeof(string));
            dt.Columns.Add("OwnerURL", typeof(string));

            //Add List info as rows
            foreach(SPList list in SPContext.Current.Web.Lists)
            {
                //can Filter the Lists by SPListTemplateType http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.splisttemplatetype.aspx
                
                DataRow row = dt.NewRow();
                row["List Name"] = list.Title;
                row["List URL"] = SPContext.Current.Web.Url + list.RootFolder.ServerRelativeUrl;
                row["Description"] = list.Description;
                row["Owner"] = list.Author.LoginName;
                row["OwnerURL"] = SPContext.Current.Web.Url + "/_layouts/userdisp.aspx?ID=" + list.Author.ID + "&Source=" + Page.Request.Url;
       
                dt.Rows.Add(row);
            }

            //Add Columns to Grid
            HyperLinkField col1 = new HyperLinkField();
            col1.HeaderText = "List Name";
            col1.DataTextField = "List Name";
            col1.DataNavigateUrlFields = new string[] { dt.Columns["List URL"].ToString() };
            GridView.Columns.Add(col1);

            SPBoundField col2= new SPBoundField();
            col2.HeaderText = "Description";
            col2.DataField = "Description";
            GridView.Columns.Add(col2);

            HyperLinkField col3 = new HyperLinkField();
            col3.HeaderText = "List Owner";
            col3.DataTextField = "Owner";
            col3.DataNavigateUrlFields = new String[] { dt.Columns["OwnerURL"].ToString() };
            GridView.Columns.Add(col3);
                 
            //Set the Datasource and bind to Grid
            GridView.DataSource = dt;
            GridView.DataBind();

        }
    }
}

Build and deploy the project! That's all, we are done creating custom SharePoint 2010 application page using visual studio 2010.
