Grid footer layout offset to one side

Hi,

We have an issue in IE 7 and onwards in all Telerik releases after 2013.1.417.40.

Two of our pages use a grid with manually calculated footers which are then added in the Footer Event. I have rolled back through various versions of the telerik toolkit and found that the footer works as expected in 2013.1.417.40, but when I run it using all later releases the footer is offset with the manually built values appearing to the right of the grid.

Are there any known issues with this feature in subsequent releases?

It only appears to manifest itself when run through IE - all versions 7 to 11 - but is OK in Firefox and Chrome.

For the moment I have had to roll back to the 2013.1 release to avoid customer complaints.

RadSearchBox bug: Supposes that there's only one form element on the page

When I tried using RadSearchBox, I found that the results drop down doesn't appear although the response is received successfully.
After some debugging, I found that the code appends the drop down element to the first FORM element it finds!
Here's the code:

b.DropDown.prototype = {

initialize: function ()

{

a(document.body).find("form").prepend(this._element);

}

ASP.Net restricts the existence of more than one FORM with runat=server, but I may have as many FORM elements as I want for other client side uses. Why supposing that there's only one FORM, while BODY should have been used for this, because there can't be more than one BODY.
