Question

How do I refresh a page in ASP.NET? (Let it reload itself by code)

I\'d rather not use Response.Redirect() because I don\'t know if the page I will be on, as it\'s i

Answer 1

In your page_load, add this:

Response.CacheControl = "no-cache";
Response.AddHeader("Pragma", "no-cache");
Response.Expires = -1;

Answer 2

I personally need to ensure the page keeps state, so all the text boxes and other input fields retain their values. by doing meta refresh it's like a new post, IsPostBack is always false so all your controls are in the initialized state again. To retain state put this at the end of your Page_Load(). create a hidden button on the page with an event hooked up, something like butRefresh with event butRefresh_Click(...). This code sets a timer on the page to fire a postback just like a user clicked the refresh button themselves. all state and session is retained. Enjoy! (P.S. you may need to put the directive in the @Page header EnableEventValidation="false" if you receive an error on postback.

//tell the browser to post back again in 5 seconds while keeping state of all controls
ClientScript.RegisterClientScriptBlock(this.GetType(), "refresh", "<script>setTimeout(function(){ " + ClientScript.GetPostBackClientHyperlink(butRefresh, "refresh") + " },5000);</script>");

Answer 3

Response.Write("<script>window.opener.location.href = window.opener.location.href </script>");

Answer 4

Try this:

Response.Redirect(Request.Url.AbsoluteUri);

Answer 5

There are various method to refresh the page in asp.net like...

Java Script

 function reloadPage()
 {
     window.location.reload()
 }

Code Behind

Response.Redirect(Request.RawUrl)

Meta Tag

<meta http-equiv="refresh" content="600"></meta>

Page Redirection

Response.Redirect("~/default.aspx"); // Or whatever your page url

Answer 6

This might be late, but I hope it helps someone who is looking for the answer.

You can use the following line to do that:

Server.TransferRequest(Request.Url.AbsolutePath, false);

Try to avoid using Response.Redirect as it increases the steps in the process. What it actually does is:

1. Sends back the page with redirection header
2. The Browser redirects to the destination URL.

As you can see, the same outcome takes 2 trips rather than 1 trip.
