Cookies in silverlight

Posted by Viral Sarvaiya on August 27, 2010

hello friends…

here i demonstrate how to set the cookies and get the values of the cookies and set the values of the cookies in the silverlight. for that i am making 2 function named GetCookie() and SetCookie().

in my project i have 2 textbox for the key and the value of the cookies then 1 button that set the value of the cookies by the key and then one button that show the cookies value by the key.

Note : For using the cookie, you have to add namespance “System.Windows.Browser”.

Step 1 : Create new silverlight project.

Step 2 : in mainpage.xaml file

<UserControl x:Class="SilverlightCookies.MainPage"
 xmlns:d="" xmlns:mc=""
 mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480">
 <Grid x:Name="LayoutRoot" ShowGridLines="True">
 <ColumnDefinition Width="400"></ColumnDefinition>
 <ColumnDefinition Width="200"></ColumnDefinition>
 <RowDefinition Height="200"></RowDefinition>
 <RowDefinition Height="200"></RowDefinition>
 <RowDefinition Height="200"></RowDefinition>

 <TextBlock Name="lblKey" Text="Key : " Grid.Column="0" Height="30" Grid.Row="0"></TextBlock>
 <TextBox Name="txtCookieskey" Grid.Column="0" Grid.Row="0" Width="200" Height="30" Margin="0,0,0,0"></TextBox>
 <TextBlock Name="lblValue" Text="Value : " Grid.Column="0" Height="30" Grid.Row="0" Margin="0,70,0,0"></TextBlock>
 <TextBox Name="txtCookiesValue" Grid.Column="0" Grid.Row="0" Width="200" Height="30" Margin="0,70,0,0"></TextBox>
 <Button Name="btnSetCookies" Grid.Column="0" Grid.Row="1" Content="Set Cookies" Width="100" Height="30" Click="Button_Click"></Button>
 <TextBlock Name="LblCookies" Grid.Column="0" Grid.Row="2"></TextBlock>

 <Button Name="btnGetCookies" Grid.Column="1" Grid.Row="0" Content="Get Cookies" Width="100" Height="30" Click="Button_Click_1"></Button>
 <TextBlock Name="LblDisplayCookies" Grid.Column="1" Grid.Row="1" Width="auto" Height="auto"></TextBlock>


Step 3 : my mainpage.xaml.cs file

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using System.Windows.Browser;
namespace SilverlightCookies
 public partial class MainPage : UserControl
 public MainPage()

 private void SetCookie(string key, string value)

 DateTime expireDate = DateTime.Now + TimeSpan.FromHours(1);
 string newCookie = key + "=" + value + ";expires=" + expireDate.ToString("R");
 HtmlPage.Document.SetProperty("cookie", newCookie);

 private string GetCookie(string key)
 string[] cookies = HtmlPage.Document.Cookies.Split(';');
 foreach (string cookie in cookies)
 string[] keyValue = cookie.Split('=');
 if (keyValue.Length == 2)
 if (keyValue[0].ToString().Trim() == key.Trim())
 return keyValue[1];
 return null;

 private void Button_Click(object sender, RoutedEventArgs e)
 SetCookie(txtCookieskey.Text.Trim(), txtCookiesValue.Text.Trim());
 LblCookies.Text = "Cookes has been Created";

 private void Button_Click_1(object sender, RoutedEventArgs e)
 LblDisplayCookies.Text = GetCookie(txtCookieskey.Text.Trim());
 LblCookies.Text = "Display Cookies of " + txtCookieskey.Text;

Step 4 : Run the application…

for this you get 2 textbox and 2 button.

when i input the key and value in the textbox and press button of “Set Cookies”, it set the key of cookies by that value and when i click on “get Cookies” by typing key value in key textbox, it show me the value of the key in cookie.

Enjoy Coding……..
