Filtering issue with dhtml grid


We recently implemented dhtml grid in our products. It is really nice having wide features.
We are facing the filtering issue with the grid as explained below.

My grid has three columns and the first column is attached with #combo_filter header.
Let us say first column contains values 1,2,12,21. If I select the 2 from filter, it is displaying three rows containg 2,12 and 21. I want to filter with complete word match.

Please advice us as it become critical to our requirement.

Thanks & Regards,

It can be done only with custom filter creation. Please find more information here

As alternative solution you can try to use
If will show only results with full match
