Session State being lost in Internet Explorer but not Firefox [modified]

Hi,

I'm having a problem with session state being lost in the live environment when using Internet Explorer Versions 6,7 or 8.

The application I am working on is www.rugbyroundup.com[^]. The behaviour should be that when a user selects a country they get a different country based page, with different Fixtures and Results available. Then, when clicking on the various Leagues, they should stay with that country. For instance, if you were to select England, followed by National 1 you would still see the England Bar after selecting the National 1 League.

This is happening correctly in Mozilla Firefox. However, in Internet Explorer, after clicking the League, the Country setting returns to international!!! Mad | :mad:

(this can be seen by the change of the flags towards the top of the page).

What is equally infuriating is that when testing against my local development version, it functions perfectly on both browsers!!!

I've done a bit of investigation into the problem. As the page is using IFRAMES I had a look at the article Session variables are lost if you use FRAMESET in Internet Explorer 6[^] but after giving the various resources the appropriate HTTP Headers the problem is still occurring.

I also looked at the Trace when the pages are being run - here is a summary:

LIVE
====

Mozilla
Browse to index
index fires twice with same session variables

select country
index fires twice with same session variables

Got to League
Fires twice with same session variables

IE
Browse to Index
index fires once with correct session variables.

Select country
index fires twice, Second time, the Country code is changed, almost reset

Local
=====
Mozilla
Browse to index
index fires twice with same session variables

select country
index fires twice with same session variables

Got to League
Fires at least once --- does fire twice - page load occurred twice, thread stack was overflown...

IE
Browse to Index
index fires once with correct session variables.

Select country
index fires once with correct session variables

Select League
league.aspx fires once with correct session variables.

I would be grateful for any help with this problem

What do you mean?
Textboxes are generally used to input data from the user.

You want to set the size of the textbox while user types something to the textbox. This is weird.

If this is so, then what size means, you mean width of the textbox. You can set width using javascript.

Confused | :confused:

Enable options according to button click

18-Jun-09 2:05

This will solve your problem to some extent:
<pre>
<asp:TextBox ID="TextBox1" runat="server" onkeypress="return dWd(this);" onkeyup="return dWd2(this);" onkeydown="return dWd2(this);" Width="20"></asp:TextBox>

<script language="javascript">
function dWd(e)
{

var wt=parseInt(e.style.width);
wt+=10;
e.style.width=wt + "px";

}

function dWd2(e)
{
if(event.keyCode==8)
{
if(parseInt(e.style.width)>20)
{
var wt=parseInt(e.style.width);
wt-=10;
e.style.width=wt + "px";
}
}
}
</script>

Assuming your first row of gridview is the last inserted record

in design mode provide backcolor in SelectedRowStyle or in your CSS.
then in ur insert function after Binding gridview write the below line

gridview1.SelectedIndex = 0;

The Code

In order to run the code below, you must first set up Membership. The simplest way to do this is to simply add to your web.config a very small section enabling RoleManager. This will automatically create the membership database in sqlexpress. You should probably add a couple users just so your gridview is not empty from the start. The code you need to add to an empty asp.net 2.0 web site project is as follows (put it in the <System.Web> section).

<roleManager enabled=“true“></roleManager>

Once you have done that, you can copy the code below to a new web page and simply run it.

Briefly, the way the code works is that when a row is inserted into the database the sqldatasource’s Inserted event is called. In this event, we take a look at the return parameter which comes from the sql:

InsertCommand=”INSERT INTO [Names] ([name]) VALUES (@name);SELECT @NewID = Scope_Identity()”

NewId is actually a return parameter, so we can get that back in the inserted event. Once we get the value back, we store it in viewstate so that on the upcoming page_prerender, we can check and see which row has that id in it, and then highlight that row. The reason we do it in prerender and not load is because the inserted event is processed after load and it would not work if we put it there.

So, here is the code! Good luck.

<%@ Page Language=”C#” %>

<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>

<script runat=”server”>

// simple table named: Names. Two columns: id int, name varchar(64)

protected void ButtonInsert_Click(object sender, EventArgs e)

{

SqlDataSource1.InsertParameters["name"].DefaultValue = DateTime.Now.ToString();

int numInserted = SqlDataSource1.Insert();

GridView1.DataBind();

}

protected void SqlDataSource1_Inserted(object sender, SqlDataSourceStatusEventArgs e)

{

object newId = e.Command.Parameters["@NewId"].Value;

ViewState["NewId"] = Convert.ToInt32(newId);

}

protected void Page_PreRender(object sender, EventArgs e)

{

string newIdLast = string.Empty;

if (ViewState["NewId"] != null)

{

int newId = (int)ViewState["NewId"];

newIdLast = newId.ToString();

int rowCnt = 0;

foreach (GridViewRow row in GridView1.Rows)

{

string newIdText = row.Cells[1].Text;

if (newIdText.Equals(newIdLast))

{

//GridView1.EditIndex = rowCnt;

//GridView1.SelectedIndex = rowCnt;

row.Attributes.Add(“bgcolor”, “Gray”);

break;

}

rowCnt++;

}

}

}

You'll need to buy third party software (or create a database with every possible address yourself but I doubt you'll want to do that. QAS is a popular product but it isn't cheap IIRC.
