I am migrating Excel Documents into Line of Business application into web pages. Which means everything excel can do, my client expect the telerik controls to do! On either a RadGrid or RadGantt I would like to be able to rotate the headings just like in Excel. An example is a heading like 'Days' but the actual value in that column is no bigger than 99. Another example if that the heading has a question, and the cell a check box.
