filtering options for system.string column

[Dave]

I am wondering why the following options are showing up in the FilterMenu for a column that I have defined as a system.string:

GreaterThan
LessThan
GreaterThanOrEqualTo
LessThanOrEqualTo

I don't understand why numeric filters are showing up on a column defined as a string.  Here is how the column is set up:

<telerik:GridBoundColumn DataField="request" HeaderText="Request" SortExpression="request" DataType="System.String" UniqueName="request" FilterListOptions="VaryByDataType"></telerik:GridBoundColumn>

Hello Dave,

You can use these to filter strings as well. For example "A" is less than "S".

Kind regards,

Thanks for the clarification.  I'm just not used to seeing LessThan or GreaterThan with strings, but I guess it makes sense.  Thanks!
