I have three text boxs
1.txtname
2.txtage
3.txtmobile
and one dropdownlist
1.ddlcity
for search client information.
My requirement is when search button click the client information will bind in gridview based on data filled in textbox and dropdown list.
The difficulty is user can enter any combination for search.
eg.
1.age only
2.name and city
3.city only etc.
how can i achieve this......
