I removed the elements with tag <dcl> and the attached server-side events in order to run the page. After that I ran the page under IE6 and after adding the following CSS style:
| <style type="text/css">
| html, body, form
| height: 100%;
| padding: 0px;
| margin: 0px;
in the MastrePage's head the layout looked as expected as you can see from the attached screenshot.
Would you please make sure that the above shown CSS is present on your MasterPage and also all the RadSplitter's parent elements' heights are explicitly set?
In case this does not help, please send me a sample, fully runnable reproduction demo along with a detailed explanation of the reproduction steps and some screenshots. Once I receive it, I will do my best to help you solve the problem.
