I have a scenario in which we have user definable columns for a grid, including hundreds if not thousands that need to be ported from the old version of our product. This means these column keys would be strings that may contain spaces or even special characters - and as such cannot be a valid C# property name (which means using an ExpandoObject approach will not work)

It would be really beneficial if the TelerikGrid component could be given Data of an IEnumerable<Dictionary<string, object>> where the Field property of GridColumn (or a new property) would line up with a key in that dictionary rather than a field name for the component to then use reflection with.

A customer with multiple modules of our product installed may very well have columns with similar names, i.e "Some Key", "SomeKey", "Some_Key", "Some & Key" - so simply replacing spaces or special characters may not always still give unique keys.
