Set Session object using client-side code JavaScript

Hello Sonia,

To set Session object you need a bit AJAX
Just create ax extra asp.net page which accepts the parameter(s) you need to set and then just call the page with the necessary parameter(s)

For example (very basic example):

[FONT=courier new]var query = "setsession.aspx?sessionvalue= " + some-client-side-value;[/FONT]
[FONT=courier new]  request = new ActiveXObject("Microsoft.XMLHTTP");[/FONT]
[FONT=courier new]request[/FONT][FONT=courier new].open("POST", [/FONT][FONT=courier new]query[/FONT][FONT=courier new], true);                [/FONT]
[FONT=courier new]request[/FONT][FONT=courier new].send();[/FONT]

Setsession.aspx.cs

[FONT=courier new]private void Page_Load(object sender, System.EventArgs e)[/FONT]
[FONT=courier new]{[/FONT]
[FONT=courier new]    if(Request.QueryString["[/FONT][FONT=courier new]sessionvalue[/FONT][FONT=courier new]"] != null)[/FONT]
[FONT=courier new]    {[/FONT]
[FONT=courier new]         Session["[/FONT][FONT=courier new]mysession[/FONT][FONT=courier new]"] =Request.QueryString["[/FONT][FONT=courier new]sessionvalue[/FONT][FONT=courier new]"].ToString();[/FONT]
[FONT=courier new]    }[/FONT]
[FONT=courier new]}[/FONT]

nb. the previous post isn't cross browser compatible - you might want to use an AJAX framework

This is a VB.NET version of previously published sample code:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
      If Request.QueryString("sessionvalue") isNot Nothing Then 
            Session("mysession") = Request.QueryString("sessionvalue").ToString()
      End If
End Sub

I think you meant

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
      If Request.QueryString("sessionvalue")[B] Is Not Nothing[/B] then 
            Session("mysession") = Request.QueryString("sessionvalue").ToString()
      End If
End Sub
