IsPostBack always being true on every refresh in your ASP.NET

Ishika Tiwari

It appears that I have a page with 2 views. When you refresh the page, the postback is initially false. However, after clicking a submit button, the postback becomes true, and the 1 view changes to view 2. Now, when you refresh the page again, the postback is true, but i want it to be false.

Initially, after refreshing the page, the postback is false.
After submitting the form, the postback becomes true, and the view changes.
Subsequent page refreshes result in a true postback, but i want it to be false.

After processing the form submission, use the Post-Redirect-Get pattern. This involves redirecting the user to another page (typically the same page) after a successful form submission. This way, when the user refreshes the page, it won't trigger another form submission.
```
protected void SubmitButton_Click(object sender, EventArgs e)
{
    // Process form submission

    // Redirect to the same page to avoid postback
    Response.Redirect(Request.Url.AbsoluteUri, false);
}
```

Hello Ishika,

you need to check your page is loaded first time or nor, in this case

If the page is loaded for the first time or is refreshed without triggering a postback, IsPostBack will be false.

IsPostBack will not always be true on every refresh in ASP.NET WebForms. It will be true only when the page is loaded in response to a postback.
