Page Name : AboutUs.aspx
Controls Available on Page : AboutUs.aspx
-----------------------
Controls ID

Steps:
1. Based on the PageName selected, Get that page
2. Loop through all the controls of that page

foreach (Control c in Page.Controls)
{       
  // control c
  // c.ID;
  // c.GetType
  // all control properties accessible
  // store this in a table
}

3. Maintain a table. Store all the things needed.
4. display the table in a Datagrid.

You have to design your website such that the pages are derived from some BasePageClass such that having a page reference is easy for you.

Step 1. All the Page Names in Dropdown

Add ddlPageNames Dropdown on aspx Page

C#

protected void Page_Load(object sender, EventArgs e)
   {
       if (!IsPostBack)
       {
           string[] filePaths = Directory.GetFiles(@"D:\WebSite1\", "*.aspx");
           foreach (String item in filePaths)
           {
               char c = '\\';
               String[] Filter = item.Split(c);
               ddlPageNames.Items.Add(Filter[2]);
           }
       }
   }

Step 2. Create a Sample Page where you can load another page with in using iFrame Object and Collect all the Control Properties and Save them into Session.

XML

<p>
    <iframe id="I1" runat="server" name="I1" width="0" height="0" src="Default.aspx" visible="true">
    </iframe>
   <asp:DropDownList ID="ddlPageNames" runat="server" AutoPostBack="true" onselectedindexchanged="ddlPageNames_SelectedIndexChanged"></asp:DropDownList>
        <asp:Button ID="btnListControls" runat="server" Text="Button" onclick="Button1_Click" />
        <asp:Label ID="TotalControls" runat="server"></asp:Label>
        <asp:GridView ID="GridView1" runat="server"
        onpageindexchanged="GridView1_PageIndexChanged"
        onpageindexchanging="GridView1_PageIndexChanging"
        onrowdatabound="GridView1_RowDataBound" >
        </asp:GridView>
</p>

C#

protected void btnListControls_Click(object sender, EventArgs e)
   {
       DataView dt;
       dt = (DataView)Session["dtData"];
       if (dt != null)
       {
           GridView1.DataSource = dt;
           GridView1.DataBind();
       }
   }
   protected void ddlPageNames_SelectedIndexChanged(object sender, EventArgs e)
   {
       I1.Attributes["src"] = Convert.ToString(ddlPageNames.SelectedValue);

   }

Step 3. Now Bind the Stored Control Names into Gridview to List all.

For Instance :

Suppose You Want to List all Controls Available on Default.aspx Page then Follow

C#

 DataTable dt = new DataTable();
 DataView objDV = new DataView();


protected void Page_Load(object sender, EventArgs e)
    {
        
        
        dt.Columns.Add("Ctrl", typeof(string));
        dt.Columns.Add("Name", typeof(string));
        foreach (Control ParentMain in Page.Controls)
        {
            #region //CurrentPage
            Page objpage = new Page();
            string sPath = System.Web.HttpContext.Current.Request.Url.AbsolutePath;
            System.IO.FileInfo oInfo = new System.IO.FileInfo(sPath);
            string sRet = oInfo.Name;
            //txtControlsList.Text = Convert.ToString(txtControlsList.Text) + sRet + "\n";
            //txtControlsList.Text = Convert.ToString(txtControlsList.Text) + ParentMain.ID+"\n";
            foreach (Control Child1 in ParentMain.Controls)
            {
                //txtControlsList.Text = Convert.ToString(txtControlsList.Text) + Child1.ID + "\n";
                FillControlList(Child1);
                foreach (Control Child2 in Child1.Controls)
                {
                    //txtControlsList.Text = Convert.ToString(txtControlsList.Text) + Child2.ID + "\n";
                    FillControlList(Child2);
                    if (Convert.ToString(Child2.ID) == "GridView1")
                    {
                        GridView myGridView1 = (GridView)Page.FindControl("GridView1");
                    }
                    #region
                    foreach (Control Child3 in Child2.Controls)
                    {
                        //txtControlsList.Text = Convert.ToString(txtControlsList.Text) + Child3.ID + "\n";
                        FillControlList(Child3);
                        if (Convert.ToString(Child3.ID) == "Button1")
                        {
                            Child3.Visible = false;
                        }
                        foreach (Control Child4 in Child3.Controls)
                        {
                            FillControlList(Child4);
                            if (Convert.ToString(Child4.ID) == "Button1")
                            {
                                Child4.Visible = false;
                            }
                            foreach (Control Child5 in Child4.Controls)
                            {
                                FillControlList(Child5);
                                if (Convert.ToString(Child5.ID) == "Button1")
                                {
                                    Child5.Visible = false;
                                }
                            }
                        }
                    }
                    #endregion
                }
            }
            #endregion
        }
        objDV = dt.DefaultView;
        Session["dtData"] = objDV;
}


Next 

 public void FillControlList(Control Ctrl)
    {
        ListItem li = new ListItem();
        li.Text = Convert.ToString(Ctrl.ID);
        li.Value = Convert.ToString(Ctrl.ID);
        if (!string.IsNullOrEmpty(Convert.ToString(li.Text)))
        {
            DataRow row = dt.NewRow();
            row["Ctrl"] = Ctrl.ID;
            dt.Rows.Add(row);
            dt.Rows[dt.Rows.Count - 1][1] = Ctrl.GetType().Name;
        }
    }
