how to set(get) cookie value in ext.net
scene: when I click item in ext:ComboBox and want to set the item selected value to cookie variable. Finally, after I click ext:Button, the ext:Label get cookie value and display it.
But I get a error :Ext.Ajax Communication Failure , any he开发者_开发问答lp will be appreciated.
aspx:
<ext:ComboBox ID="ComboBox1" runat="server" StoreID="Store1" Width="100" Editable="false"
DisplayField="name" ValueField="value" Mode="Local" TriggerAction="All`enter code here`" EmptyText="Select a locale...">
.....
aspx.cs
protected void lngIndexChanged(object sender, DirectEventArgs e)
{
//Sets the cookie that is to be used by Global.asax
HttpCookie cookie = new HttpCookie("CultureInfo");
cookie.Value = ComboBox1.SelectedItem.Value ;
Response.Cookies.Add(cookie);
Label1.Text = cookie.Value;
//Set the culture and reload for immediate effect.
//Future effects are handled by Global.asax
Thread.CurrentThread.CurrentCulture = new CultureInfo(ComboBox1.SelectedItem.Value);
Thread.CurrentThread.CurrentUICulture = new CultureInfo(ComboBox1.SelectedItem.Value);
}
I tested your code and it appears to work correctly. No Exceptions were thrown and the Cookie .Value is persisted properly.
Here's a sample demonstrating the full scenario including a second Button for fetching the Cookie .Value on a future request.
Example
<%@ Page Language="C#" %>
<%@ Import Namespace="System.Threading" %>
<%@ Import Namespace="System.Globalization" %>
<%@ Register assembly="Ext.Net" namespace="Ext.Net" tagprefix="ext" %>
<script runat="server">
protected void ComboBox1_Select(object sender, DirectEventArgs e)
{
// Sets the cookie that is to be used by Global.asax
HttpCookie cookie = new HttpCookie("CultureInfo");
cookie.Value = this.ComboBox1.SelectedItem.Value;
this.Response.Cookies.Add(cookie);
this.Label1.Text = "Cookie Value: " + cookie.Value;
// Set the culture and reload for immediate effect.
// Future effects are handled by Global.asax
Thread.CurrentThread.CurrentCulture =
new CultureInfo(this.ComboBox1.SelectedItem.Value);
Thread.CurrentThread.CurrentUICulture =
new CultureInfo(this.ComboBox1.SelectedItem.Value);
}
protected void Button1_Click(object sender, DirectEventArgs e)
{
this.Label1.Text = "Cookie Value Again : " + this.Request.Cookies["CultureInfo"].Value;
}
</script>
