Question

I have an ASP.NET web page that has an advanced search tab. Within this tab I have 10 fields that can be used to refine the search further. I want to write a single method to handle all of the permutations that result from this search.

What is the best way to achieve this? I know that I cannot create a search object to hold all the values and pass that in because the object cannot be exposed from the business layer to the UI layer).

Answer 1

var query = dc.MyTable; // Base query here
if (Field1.Text != "") // Filter Field1
    query = query.Where(x => x.Field1 == Field1.Text);

if (Field2.Text != "") // Filter Field2
    query = query.Where(x => x.Field2 == Field2.Text);

grid.DataSource = query;
