Hello,
I've got a problem with filtering string field using "between" and "not between" options from the standard available filter list. It just throw exception like "Operator '>=' incompatible with operand types 'Object' and 'String' (at index 20)"
ne.
I looked around the forum and I found out it can be "EnableLinqExpression" issue. So I add to my radGrid ( on the aspx page)
EnableLinqExpression=false. And all works fine!
Unfortunately another filter for the datetime field stoped working with "between" and "not between" options. This particular field filtering is handled separately by "OnItemCommand" (to allow filtering date without time).
What could be the best solution for this problem?
My telerik version is: 2008.3.1125.35
Thanks in advance,
Tom

Hi Tomasz,
Indeed the built-in GridDateTimeColumn do not allow between filter since the parsing mechanism of the date input (part of the date picker used for filtering) allows merely one date to be entered. To apply 'Between' filter you should either use the approach with two pickers in the filter template from the demo (OrderDate column) or built-in GridBoundColumn with textbox filter.
Kind regards,
