Question

If you go to http://ifdefined.com/btnet/bugs.aspx you will see a long list of sample data in an asp.net gridview control. What I need to do is something similar. I need to implement the filtering system by placing dropdown controls with dynamic values on the headers and then filter the record according to them.

If you look carefully they are filtering the data based on multiple drodown selections as well.

Kindly help me out. Any kind of input is highly appreciated.

Thanks in advance for your time.

You can:

1. set the dropdownlists to
   autoPostback=true
2. Reload the
   data in the Dropdownlist
   selectionChnaged event. Give the
   gridview a new dataset with the
   applied filter and call DataBind()
3. Place the griview + Dropdownlist into an UpdatePanel for ajax functionality
