Creating dynamic reports using the report viewer control visual studio 2010

I am attempting to create a dynamic report using the report viewer control that comes with Visual Studio 2010 pro. It is pulling the data in from my tables correctly, but what I need it to do is to show the data based on user input. Basically, what I need is something like this.

if(cert_number == int.Parse(txtcertnum.text))
{
     // get the report control to display this record
     report_control.Refresh();
}

Select allOpen in new window

Note, the language is C#
