Hi,
We are using RadSearchBox on one of our ASP.NET WebForms application pages and have noticed browser memory leaks running in IE8 (using
sIEve to detect the memory leaks).
It appears that leaks occur when SearchContextItems are added to the RadSearchBox.
I have created a sample app that demonstrates the leaks. The sample app is built in VS2012 .NET 4.0 using Telerik RadControls for Ajax Q3 2013 v 2013.3.1114.40.
Attached is screenshot of sIEve results. Memory usage in red is when I reloaded the page (ie, click Go button). Memory usage in green is when I unloaded the page (ie, clicking about:blank).
It is likely that upgrading to a newer browser would correct the leaks, but unfortunately, we're mandated by corporate IT to use IE8 and have no choice for upgrading the browser (Chrome and Firefox are not an option either).
Thanks in advance for any assistance you can provide.

Hi,
In the index.aspx of my web application i'm using a RadAjaxPanel do paginate a repeater . On top of the page is a list from A to Z where the user can navigate throught the letters for a faster pagination.
What i need is to enable the browser history for this pagination.
I have enabled the "EnableHistory=true" on the RadAjaxPanel and add some history point on the server side.
The browser history now shows every pagination, what is perfect.
But the problem is that when hit the back button on the browser, the event OnNavigateHistory is never called.
The question is : Is that possible to use RadAjaxPanel on this scenario ? How can I do it ?
Thanks,
Alfredo

I had sorting, paging, and filtering all working together with a Object Data Source in the ASP.Net version. I can get the paging and sorting to work in the new ASP.NET AJAX version, but I am having a problem with paging when using a filter. Apparently, the maximumRows parameter of the data source is returning 2147483647 instead of 10 which is the value defined in the Page Size property. The maximumRows parameter works fine while paging and sorting, so I don't understand why it doesn't seem to work while paging and filtering.

I've inserted RadCaptcha control on login.aspx page.I've radscriptmanager on the same page.
when I run this page,in Firebug i found "src" property of image sets to -
src="../Telerik.Web.UI.WebResource.axd?type=rca&guid=bff339e1-b3e3-4af8-aaca-0ca8cf274883"
& if I hover mouse on this property it says "failed to load given URL."
but on other page I tried the same thing and found that src sets to
src="Telerik.Web.UI.WebResource.axd?type=rca&guid=bff339e1-b3e3-4af8-aaca-0ca8cf274883"
Difference is only "../"
Can you please tell me how to solve this problem?
In Firebug,If I manually remove syntax "../" from src property then only Image loads.
Please reply ASAP.
Thanks

Buttons btnActivatebutton and btnInactiveButton show up like normal text. User will not know that they are buttons until they hover over them. I need fix for this. Thnaks.
