Why it is always: this.IsPostBack = false?

Hello, friends,

Help please, this has driven me nuts:

I am developing the default.aspx page. In this page, we allow a user to type
user name/password, and then click on Submit button to login.

<form name="form1" onsubmit="return isValidInput()" action="default.aspx"
method="post">
....
<INPUT type="submit" value="Submit" id="submit">
</form
In Page_Load(), we have a statement to check if this is a postback:

If (this.IsPostBack)
//verifying login info and direct to proper page
else
//display default page

However, for some reason, this.IsPostBack was always false, no matter it was
the first time to view default.aspx from IE or after a user typed a valid
user name/pswd and clicked on Submit button.

Any ideas?

Thanks a lot.> Hello, friends,

I'm not 100% but have you tried using the Server Button control instead?

Kev
You need to drag the <asp:button> onto your form.

NOT the html control "submit button"

...

What you don't see is that with the <asp:button>... ASP.NET is wiring up a
bunch of events for you.

DRAG and DROP the button, don't try to create it by handtyping.

Instead of :
<form name="form1" onsubmit="return isValidInput()" action="default.aspx"
method="post"
Try :

<form id="form1" onsubmit="return isValidInput()" runat="server" action="default.aspx"
method="post"
( You are missing the "runat" attribute...)

That would be advisable, too, but the main problem is
that his form didn't have the runat="server" attribute.
