CRUD operation on below form on submit button Click

Hi All,

I am trying to build following sample.

https://msdn.microsoft.com/en-us/library/gg695790(v=crm.7).aspx

My Solution looks like below for DisplayCreateContactView.

<%@PageTitle=""Language="C#"MasterPageFile="~/Site.Master"AutoEventWireup="true"CodeBehind="WebForm_FromSavedQuery.aspx.cs"Inherits="WebApplication1.WebForm_FromSavedQuery" %>

<asp:ContentContentPlaceHolderID="HeadContent"runat="server"/>

<asp:ContentContentPlaceHolderID="MainContent"runat="server">

<asp:ScriptManagerrunat="server"/>

<crm:CrmDataSourceID="Contacts"runat="server"/>

<crm:CrmEntityFormViewDataSourceID="Contacts"EntityName="contact"SavedQueryName="Create Contact Webform"runat="server"/>

</asp:Content

1. How I can Perform basic CRUD operation from above form on submit button Click?

2. Also, Can I use fileuploader to upload the document from csv file to perform bulk CRUD operation?

Any help greatly appreciated.
