Filtering Report using user-defined values from textBoxes

Question

I have Windows Forms Application (VS-2008) with Access database, and I'm using MicrosoftReportViewer. My problem is how to set filter to report. Something like: Column1.Value=textBox1.Text, and Column2.Value between dateTimePicker1 and dateTimePicker2 selected values. I don't know how to write filter/expression for that cases.

Please, help me.
