Hi..
Welcome to Csharpcorner
Normally this error occur when we are trying to access the resource which is not available. In your case check out view.aspx location means see is it present in any directory.If it is then try like

Hyperlink.NavigateUrl = "~/view.aspx?ReturnUrl=" +
HttpUtility.UrlEncode(Request.Url.AbsolutePath); 
As well your target url must be able to Decode.
