How to fetch data from Microsoft Dynamics CRM OnPremise and show them on Gridview with Search, Select, Paging and Sorting feature in Asp.Net, C#

In this blog I am going to show how we can fetch data from Dynamics CRM OnPremise and Show them in a gridview on Web Page. Not only this but also following points:

Selecting value of row by clicking anywhere on a row.
Searching data in Gridview.
Sorting of data in Gridview.
Paging in Gridview.

First of all take a Textbox for serach box and Gridview on your web page and place below code::

 <form id="form1" runat="server">  

     <script type="text/javascript">
       function RefreshParent(row) {
         if (window.opener != null && !window.opener.closed) {
             var message = "";
             message += "Id: " + $("td", row).eq(0).html();
             message += "\nName: " + $("td", row).eq(1).html();
             alert(message);
           window.opener.location.reload();
         }
       }
       window.onbeforeunload = RefreshParent;
     </script>
     <div>
       <div>
         Search:
     <asp:TextBox ID="txtSearch" runat="server" />
         <asp:Button Text="Search Account " runat="server" OnClick="Search" /><div>&nbsp;</div>
       </div>
     <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
     <script type="text/javascript">
       $(function () {
         $("[id*=gvDetails] td").click(function () {
           RefreshParent($(this).closest("tr"));
         });
       });
     </script>
     <asp:GridView ID="gvDetails" runat="server" OnRowDataBound="gvDetails_RowDataBound" OnSorting="gvItemGrid_Sorting" AllowPaging="True"
       OnPageIndexChanging="gvDetails_PageIndexChanging" PageSize="3"
        DataKeyNames="name" AllowSorting="True" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3">
       <FooterStyle BackColor="White" ForeColor="#000066" />
       <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
       <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
       <RowStyle ForeColor="#000066" />
       <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="#660033" />
       <SortedAscendingCellStyle BackColor="#F1F1F1" />
       <SortedAscendingHeaderStyle BackColor="#007DBB" />
       <SortedDescendingCellStyle BackColor="#CAC9C9" />
       <SortedDescendingHeaderStyle BackColor="#00547E" />
     </asp:GridView>
     </div>
   </form>

Now add below code in code window::
