We are trying to update our site which is on 11.1 controls to the new controls. And we noticed that on IE !0 when we have a webhierarchicaldatagrid, the whole page is reduced to only half of the webpage size and the other half is empty, meaning the grid shrinks itself to half the page.

What could be a possible fix for this? In addition we have frames on this page plus the webtab control

Please help!
