ASP.net Postback - Scroll to Specific Position

Question

I have an ASP.net WebForms page that has a lot of content on the top of the screen. It has a link button that will post back to the page and show another section of the page

Answer 1

I've tried Matthieu Charbonnier answer, but it didn't work unless I've added

" window.scrollTo = function () { };" 

as it was suggested in http://gnidesign.blogspot.com.au/2011/06/how-to-maintain-page-scroll-on-postback.html

I've created a helper method, that's working in Chrome,FireFox and IE

public static void ScrollToControl( Page page, string clientId, bool alignToTop)
 {
     //NOTE: if there are more than one call on the page, first one will take preference
     //If we want that last will take  preference, change key from MethodBase.GetCurrentMethod().Name to anchorName
     //recommended in http://gnidesign.blogspot.com.au/2011/06/how-to-maintain-page-scroll-on-postback.html              
     String script = " window.scrollTo = function () { };" + Environment.NewLine;
     script += String.Format("document.getElementById('{0}').scrollIntoView({1});" , clientId, alignToTop.JSToString());
     page.ClientScript.RegisterStartupScript(TypeForClientScript(), MethodBase.GetCurrentMethod().Name, script, true );
     //return script;
 }
 public static string JSToString(this bool bValue)
 {
     return bValue.ToString().ToLower();
 }

Use getElementById('{0}').scrollIntoView is simpler than location.hash , because you don't need to add extra anchor element.

Parameter alignToTop is very convenient to specify do you want to show control at the top or bottom of the screen.
