Gridview binding based on user's selections

Tags: microsoft, dotnet, visual studio 2008, C#.net
Hi There,
         I have a Grid view in my asp.net application . I have a textbox and 2 dropdownlists.

Textbox===users will enter a product number

Dropdownlist1---product groups
Dropdownlist2---product subgroups

Those two dropdown lists are populated from a oracle table.

The functionality is the users can submit their parameter in any combinations like they would just enter a product number and click show button , then the gridview has to get the data related data and bind it.  For example

if textbox1.text.toString !=""

sql query
grdview binding

if textbox1.text.tostring!="" and dropdownlist 1.selected index>0

sql query
gridveiw binding

i----
----

all the combinations.

I want to know what would be the best way to do this. i feel its not worth to call the sql query , oracle connection and gridview binding each time under if conditions.,but iam not sure if that is the only way. could you please suggest me what would be the efficient way so that whatever parameter they submit in whatever combinations the sql query should take the appropriate parameter and bind it to the gridview.

Please advise me

Thanks
