SQL 2005
NO code-behind page

Hello.  I have a search page that queries a SQL 2005 db for records by "State" from a dropdown list.  That works great.

I would like to, however, add other dropdown lists to search by different parameters (ie. "City", "Type", "County", "Title", etc.).  They can use the same gridview, if possible, or somehow manipulate the Show/Hide parameters to only display certain gridviews based on the Request.Form currently being used.

Either way - I have not been successful with more than one dropdown list control being used on the same page.

Is there a way to do that?
If so, how?
If not - what would be the best way to go about achieving that?

I am new to .NET, but I am comfortable with Classic ASP, if that makes a difference; which, from what I'm seeing with .NET --- it doesn't make a difference.  

I will attach the code for the page, but the link to which I'm referring is:

The easiest way I've found to do this is to do the following:

1) Create your page with all the filter/search fields
2) Either set them to autopostback (for ddls) or create a button to click that will cause the filter
3) Create the SQL like so:

SELECT field1, field2, field3 FROM myTable WHERE State = COALESCE(@State, State) AND City = COALESCE(@City, City)

4) Use this SQL query for your SqlDataSource and bind the values to the controls created above
5) The OnClick method of the button should then just need to call MyGridView.DataBind();
