Hi all,

I have a control <asp:textbox id="myVar" runat=Server> to hold something on one of my page. When I submit the page to itself, the value of myVar does not retain. How can I fix this problem?

Thanks

John

Can you post your code?

Very simple, but the value of myVal just reset back to 0 when I debugged.

private void Page_Load(object sender, System.EventArgs e)
{

 if (!IsPostBack) {

    if ( Request.QueryString("Page") != null ) {

        // Dosomething

        myVar.Text = Convert.ToInt32(mayVar.Text) + 1 ;

   }
}

It seems like you are mixing techniques here. Your page will only set the textbox text to "value+1" on the first page hit. Is this what you want to do?

Are you sure there isn't something else in the page code that is setting the textbox text to another value?

Yes, I have alot more codes but I just want to show you the problem by cut and paste a few lines. My goal is to use that variable to hold the page index. Based on value of queryString then I will increase or decrease the variable.

I am also a bit confused about your message.
In your description you talk about myVal.

Then in your code you to try to cast the value of mayVar (notice the extra a) to an int, add 1 and assign it back to the Text property of the myVar control. That's three different names for (probably) the same stuff.

Are you sure this isn't related to a typo?

Cheers,

Imar

Forget about it. Let me tell you the problem one more time. My goal is to use 1 variable to hold the page index with a name( I don't care the name) . Based on value of queryString then I will increase or decrease the value of that variable. The problem is: the value variable never greater than 1. Every time I post the page, the variable on serverside equal 0, althought the value in aspx before I submit is 1. Sorry for confusing.
