"With the .NET 3.5 build of RadGrid for ASP.NET AJAX and LINQ filter
expressions enabled (EnableLinqExpressions = true), the filter
expressions set for the grid either internally by its filtering
mechanism or manually in code should conform to the LINQ expression
syntax instead of the old T-SQL syntax. Only thus they will be
evaluated properly by the control."
Is that means i should disable LINQ filter expressions to set the filter expressions internally?? if yes, how i can set the expressions internally for some columns and manually for others, as there is no way to enable/disable LINQ filter expressions in columns tag?
