I think you're open to criticism. In general it looks appealing.
I suggest either to change 'filter' logic or completely remove it. Extremely slow and not working right I think (ie: Try directly searching for 'reason' you get 999).

Hi, Cetin,

Yes, I'm definitely open to criticm. I defintely appreciate people pulling it down and looking at it. This is an on-going project to demonstrate the capabilities of the .NET datagrid. I've received some good feedback on ways to improve it.

As for your example, I ran it on a 4-year old, low-end pentium with just 64 MB of memory, and the filters run in about a second. What type of machine are you running on and where specifically did you run into a speed problem?

I'll look into the '999' - when I created the test data, I included the word 'reason' in the parent description table. But I'll look into it.

Thanks,
Kevin
