There is no way to know when a browser window is closed. You can do couple of tricks though

1- Set a JS timer on the client, when the timer is set, make a call to your server to end the session, then you can clean tempTable entry for the given custID.

2-Time Stamp your tempTable entry, then run a job on given interval to wipe out all expired records

3-On SessionEnd, clean your tempTable entries for the given custID

Hi Guys

You have probably heard this question before.

I sit and try to create a Master Page with nested Master Page in

That I had intended is this:

I have a Master Page (globalMaster.Master) which contain the Header and Footer.
In the Master Page I have a nested master of the left menu (leftColumnNav.master) and right menu (RightColumnNav.master)
In addition, I have Content Placeholder for my content.

My problem is that I neither get my left or right menus to show. While the text in the middle (content) is showing fine.

I lists the code (yes is f. ..... long)

What do I do wrong and is there a more clever way to do it.

Themes?

I'm using VS2008

don't post the same question again. If you make a mistake, you can use the delete button to delete the second entry.

Problem with Form and Sessions

Hi

I have a form which has a mixture of text boxes and drop down lists. The data that a user enters in through the form are sent off to a database query with the results appearing in a gridview on another page. To give the user flexibility the values they enter are stored in session variables, which after they have seen their results in the gridview page, they can click back and see their parameters. All of this works great, but I have a big problem in that the values on the form can't be changed!! Even though I can enter in new values on the form and click submit, when I see the results in the gridview, I am seeing the results of the first query, and when I click back I see the parameters of the first entry too!

Further, when I run the page in debug mode in Visual Studio 2008, I can confirm that the values in the textboxes and dropdown lists are not showing the amended values. In my submit button I do reset my Session Variables, and then give them new variables to hold by passing the values from the text boxes and dropdown lists.

So, my scratching head question is - why can't reset my form to show the new values I have entered in?

Can someone please help me!

check all the places your are setting the session variables.

It is very hard with out looking on the code to know what is going on. post some of the code snippets where you are setting your session variables

Hi
On my page load I have set a Session Flag called keepsession, which is set by the result page. If this flag is true on load of the page then the session variables, which are set when the submit button is clicked will pass the values from the sessions to the textboxes and dropdown lists, else nothing goes to them. This is working, because if I enter the form from a different part of the site, the boxes and lists are empty, which is what I want, and if I enter the page from the results page, the parameters from the first query are present.

The problem being is that I can't enter in new values to overwrite the old ones.

On my Page Load on the form page, I have

If keepsession = true then

TextBox1.Text = Session("var1")

TextBox2.Text = Session("var2")

Else

Session.Remove("var1")

Session.Remove("var2")

End If

On my button Submit

'Make sure sessions are cleared down

Session.Remove("var1")

Session.Remove("var2")

Session("var1") = TextBox1.text

Session("var2") = TextBox2.Text

'Stored Procedures go here to pass parameters to Db

Gridview takes the result from the stored procedure, which goes into a session variable. This session variable is taken in to a SqlDataSource called by the gridview to show the results on the second result page.

This is all I have done. It is not really complicated stuff.

On the debug in my button submit method and on the page load method the text boxes etc shows the values from the first query not the new values I have entered in

What do you know what the problem is?

I'd simplify as follows

Create your session variables the first time you need it. From that time, I'd not remove them at all, either I set the value or I clear the value. Then

if session variables exist then load to the text box.
TextBox1.Text = Session("var1")
TextBox2.Text = Session("var2")

In this case it will have either a previous string or String.Empty whenever you clear it.

I think this will simplify your code and you can then debug it wherever your are settings/clearing it.

just my 2cents.

Try adding the following to the start of your form_load sub:

If IsPostBack then
     Return
End If

If it works, it's because the submit button postback forces the form_load to happen, which resets the control values. The fix avoids that.

If it doesn't work, then I'm stymied.
