In this post I am going to tell you how to get IP Address of the client machine in ASP.NET 5 with C#.Net or fetch/discover IP location of the client or server machine utilizing ASP.NET with C#.Net. You can likewise put this code in your site to get or retrieve users IP address also you count the unique visitor in your website. In numerous site use this kind of usefulness so he can see that which user is visited our website. So you can likewise utilize or set this code to your site for getting the listof IP location of the users machine that are gone by your site.
The following code is to get the client IP address in ASP.NET:
<%@ Page Language="C#" AutoEventWireup="true"
CodeBehind="RetriveUserIpAddressInAspNet.aspx.cs" Inherits="ProjectDemo_Asp.et.RetriveUserIpAddressInAspNet" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>
<body>
<form id="form1" runat="server">
<div>
Client Id Address:
<asp:Label ID="lblIPddress" runat="server" Text=""
style="color: #FF0066; font-size: x-large"></asp:Label>
</div>
</form>
</body>
</html>
C#.Net code

{

{
public void Page_Load(Object sender, EventArgs e)
{
//code for print the time when the page loaded initially
lblIPddress.Text= GetLanIPAddress().Replace("::ffff:", "");
}
/*
Method to get the IP Address of the User
*/
public String GetLanIPAddress()
{
String ip = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if (string.IsNullOrEmpty(ip))
{
ip = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
}
return ip;
}
}
}

PeterIn this article, I will explain you about creating a custom configuration sections in ASP.NET 5. We want to extend ASP.NET configuration settings using XML configuration elements of your own. To do this, we produce a custom configuration section handler. The handler should be a .NET Framework class that inherits from the System.Configuration.ConfigurationSection class. The section handler interprets and processes the settings that are outlined in XML configuration elements in a specific section of a web.config file. We willl browse and write these settings through the handler's properties. And here is the code that I used:
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Linq;
using System.Web;
namespace CustomConfigSection
{
public class LoginRedirectByRoleSection : ConfigurationSection
{
[ConfigurationProperty("roleRedirects")]
public RoleRedirectCollection RoleRedirects
{
get
{
return (RoleRedirectCollection)this["roleRedirects"];
}
set
{
this["roleRedirects"] = value;
}
}
}
public class RoleRedirect : ConfigurationElement
{
[ConfigurationProperty("role", IsRequired = true)]
public string Role
{
get
{
return (string)this["role"];
}
set
{
this["role"] = value;
}
}
[ConfigurationProperty("url", IsRequired = true)]
public string Url
{
get
{
return (string)this["url"];
}
set
{
this["url"] = value;
}
}
}
public class RoleRedirectCollection : ConfigurationElementCollection
{
public RoleRedirect this[int index]
{
get
{
return (RoleRedirect)BaseGet(index);
}
}
public RoleRedirect this[object key]
{
get
{
return (RoleRedirect)BaseGet(key);
}
}
protected override ConfigurationElement CreateNewElement()
{
return new RoleRedirect();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((RoleRedirect)element).Role;
}
}
}
<configSections>
<section name="loginRedirectByRole" type="CustomConfigSection.LoginRedirectByRoleSection,CustomConfigSection" allowLocation="true" allowDefinition="Everywhere" />
</configSections>
<loginRedirectByRole>
<roleRedirects>
<add role="Administrator" url="~/Admin/Default.aspx" />
<add role="User" url="~/User/Default.aspx" />
</roleRedirects>
</loginRedirectByRole>
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using CustomConfigSection;
namespace CustomConfigSection
{
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
LoginRedirectByRoleSection roleRedirectSection = (LoginRedirectByRoleSection)ConfigurationManager.GetSection("loginRedirectByRole");
foreach (RoleRedirect roleRedirect in roleRedirectSection.RoleRedirects)
{
if (Roles.IsUserInRole("", roleRedirect.Role))
{
Response.Redirect(roleRedirect.Url);
}
}
}
}
}

In this article i will explain you how to Filter and Sorting in GridView using DataView in ASP.NET 5. First, you must create a new project and write the below code in ASP.NET:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Filter and Sorting in GridView using DataView</title>
</head>
<body>
<form id="form1" runat="server">

<td>
<asp:TextBox ID="txtId" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
Enter User Name:
</td>
<td>
<asp:TextBox ID="txtUserName" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
<asp:Button ID="btnSearch" runat="server" Text="Search"

At this short article, we will Create validation control's Error messages in Alert box in ASP.NET 5. First step, you need to know about how to show validation control's Error messages in Alert box in ASP.NET. Then, write the following code:
ASP.NET
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajax" %>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>How to show validation control's Error messages in Alert box in ASP.NET</title>
</head>
<body>
<form id="form1" runat="server">
<table>
<tr>
<td>
<asp:Label ID="lblName" runat="server" Text="Name"></asp:Label>
</td>
<td>
<asp:TextBox ID="txtName" runat="server" ValidationGroup="Validation"></asp:TextBox>
<asp:RequiredFieldValidator ID="rfvName" runat="server" ControlToValidate="txtName"
Display="None" ErrorMessage="Name is Required" ValidationGroup="Validation"></asp:RequiredFieldValidator>
</td>
</tr>

</td>
</tr>
<tr>
<td>
<asp:Label ID="lblEmail" runat="server" Text="Email Address"></asp:Label>
</td>
<td>

<asp:RegularExpressionValidator ID="regEmail" runat="server" ControlToValidate="txtEmail"

ValidationExpression="^([a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]){1,70}$">
</asp:RegularExpressionValidator>
</td>
</tr>
<tr>
