RadGrid GridBoundColumn and Filtering

[Andrew]

Hello,

My users have asked me if it's possible to filter a given column in a grid using boolean operators.  Using this demo as a example, they'd like to filter like this:

Show me all orders where the shipcountry starts with "fr" or "ge".

Is there a syntax for this when using basic/simple filtering on a RadGrid?  I don't want to use a RadFilter because it has not faired well in usability tests with this group of users.  I've tried the options listed below but they don't seem to accomplish what I'm looking for:

fr or ge
fr || ge

Can anyone tell me if this functionality is baked into the RadGrid basic filtering?

Thank you,
Andrew

Hello Andrew,

You can take a look into the following documentation.
Custom Option for Filtering (FilterListOptions -> VaryByDataTypeAllowCustom)
