Response.Redirect(url) problem

Posted by Community Admin on 27-Dec-2010 00:00

I'm having an issue attempting to redirect from one Sitefinity page to another. I have a page that sits at the following Sitefinity URL: http://schqvbid/eis/requests

It has a user control on it that contains a button. The button executes code and then performs a Response.Redirect(url); where url is a string variable set to "~/eis/request" which is another Sitefinity page.

When the code executes, it forms the url string as: schqvbid/...//eis/request/

I've tried changing my url string to every possible combination that I can think of to get it to redirect to http://schqvbid/eis/request.

What am I missing here? What is the correct way to navigate to a Sitefinity page using a redirect?

Thanks.

a little more information that I figured out...

The problem only happens when the RadGrid is ajaxified. If I remove the RadAjaxManagerProxy section, the link forms fine and I can redirect.

Is there a setting I need to add to my RadAjaxManager or RadAjaxManagerProxy to get links to form normally?

Another update...

I had been having the issue with pages that contain my User Controls and a custom Master Page needing a <asp:ScriptManager> tag on my Master Page or they would error out. Removing that tag from my Master Page doesn't cause the error any more and doing so also corrects the behavior with the Redirect url. Of course I lost all AJAX functionality on my pages as well which is probably why it also works when I remove the RadAjaxManagerProxy from this page.

Hi Philip Senechal,

It would be nice if you showed us some sample code on how you are handling the link as well as how you use your user control with RadAjaxManager. This will help us troubleshoot the error.

Hello Philip Senechal,

Thank you for getting back to me.

Have you tried this behavior in IE and Chrome? There seems to be no problem with using Response.Redirect. You can also try the bellow:

void button1_Click(object sender, EventArgs e)

string url = "~/test/redirect/";

var AjaxManager = RadAjaxManager.GetCurrent(this.Page);

AjaxManager.Redirect(url);

The problem does not appear to be related to the RadAjaxManager or the Ajax controls. The problem seems to be related to this bug in Firefox.

Best wishes,

Hi Radoslav,

Thanks for the reply. IE 7 displays the same behavior as Firefox on my computer. Unfortunately I cannot test Chrome because they won't let us install it on our laptops here.

I did however use your alternate code solution for the redirect and the problem doesn't appear when using the RadAjaxManager to do the redirect. I will use this solution. Thanks for the assistance.
