If I have a column named Source which corresponds to a property of MySourceEnum Source how do I write a filter expression for this?
So far everything I've tried along the lines of
Keeps resulting in a server exception.
Should I be using something like MySourceEnum.SourceEnumValue or perhaps the concrete name Some.Name.Space.MySourceEnum.SourceEnumValue isntead?
Also I should point out I use Nullable enums on my object incase it could be an issue with the grid not handling nullable enums correctly.

| RadGrid1.MasterTableView.FilterExpression = "[Source] = 'SourceEnumValue'" |

Having similar issue, except I'm doing it server-side using FilterExpression against a dataset that is a List<> of custom objects. Can't figure out what to specify that will make it properly filter on an Enum property. Tried the integer, tried the string, tried the string without quotes. Answer is non-obvious. Let me know what you figure out.

I got it working with this syntax (which I believe is the LINQ filter syntax as opposed to SQL-like)
| RadGrid1.MasterTableView.FilterExpression = "Source = \"EnumName\"" |

Thanks, Chris, but I'm working in 2.0, so Linq expressions are supported. Still stuck.... :(
