jQuery Grid Plugin - jqGrid

Hi,
I am using microsofts Dynamic.cs with my jqgrid searches.

    I tried to do a contains (cn) on a numeric search field and got this error:

    No applicable method 'Contains' exists in type 'Int32' 

    i am wondering if i cannot use use contains (cn) for a numeric field? Or maybe i dont have the latest version of Dynamic.cs? Or perhaps i am just doing this just plain wrong?

    after looking around, i can understand that int32 does not have a contains method, but how do i use the "cn" search option on a numeric? Or should I just use the other search options like eq, ne etc.

i found a forum post

that i thought would tell me how to fix my Dynamic.cs so that it could handle contains-(cn), but that dosnt seem to work?

i guess i am wondering what the best practice is for this issue?

thanks for your time.
