Hello, 
   I am facing problem in data filtering using gridview. i.e i can display multiple selected fields of a table in gridiview with minimum and maximum range(texboxes in grdview item template). how can i filter the data from row by row. 

the image would be like this.(this is similar to se16 tcode in sap abap).
example :
id  6  to 30
firstnamesatish chandragirito
lastname
to
zip500045to
countryindia






(note : here the fields are not fixed. if user select multiple fields by checkbox option.)

in above table first it will search for 6-30 records in the table & again it will search for satish chandragiri in firstcname of the table. 
   how it could be achievable?
kindly help me.

Thanks in Advance
Satish Chandragiri
