You've been kicked (a good thing) - Trackback from DotNetKicks.com

Thanks for the tip.

But where is ViewState["IsUserControlPostBack"] set to some value?

No, it won't. The IsPostBack property for a UserControl returns the same value as the IsPostBack property for the page. If you're getting true every time, you must be doing something unusual.

You should do a little testing on your assumption of IsPostBack always equaling true inside of a UserControl.  I'm working on a user control right now and put in Response.Write(Page.IsPostBack) and Response.Write(IsPostBack), and on a get request they both output "False".

Are you sure that IsPostBack is "always" true inside of a UserControl?

I have a project I'm working on, and the UserControl is called Contracts.ascx...Inside the Page_Load event, I have the following code:

           if (!Page.IsPostBack)

           {

               Response.Write("Can you see me?");

               SetProjectLabels();

           }

I only see the message "Can you see me?" one time...not every time the Page posts back.

Umm, IsPostBack can be false in a UserControl.  Are you sure you're not doing something else wrong?

Hi there,

Page.IsPostBack is not always true inside a control. What's the catch?

Thanks

I could Not follow. Where are you adding the value for the ViewState["IsUserControlPostBack"]

A couple of remarks.

> IsPostBack method will always be true inside user control.

This is wrong: it will be true the first time you load a UserControl dynamically in response to a page PostBack, but is not true in the general case.

> You can use following alternate method to by pass this isse

The code has a bug - looks like you copied it incorrectly from blogs.clearscreen.com/.../2838.aspx

You omitted the line:

this.ViewState.Add("IsUserControlPostBack", true);

But wouldn't Page.IsPostBack achieve this?

As far as I know, the IsPostback property works the same inside a Web User Control as it would be working inside a page.

Could you provide an example where it doesn't?

I'm sorry, I don't get this article at all. What do you mean IsPostBack is always true. Under what circumstances? If a Page is postbacked? Yes of course it is.

Could you please clarify things a bit more.

This is simply false. IsPostBack returns the proper value inside a user control. Maybe you are misguided? Is there some other issue that you or not seeing?

Please don't spread false information.

The IsPostBack property will *NOT* always return true in a UserControl - it returns the same value as the Page.IsPostBack property.
