How to combine 2 dataGridView filters

Question

I have a Windows Form program in C#.

 

I have a dataGridView with several columns and where 2 columns are State and Country

 

I have 2 comboBoxes populated with all items from the State and County

 

 My code for the 2 filters are:

 

BindingSource bs = new BindingSource();

bs.DataSource = dataGridView1.DataSource;

bs.Filter = "[State] Like '%" + FilterState.Text + "%'" ;

dataGridView1.DataSource = bs;

 

BindingSource bs = new BindingSource();

bs.DataSource = dataGridView1.DataSource;

bs.Filter = "[Country] Like '%" + FilterCountry.Text + "%'";

dataGridView1.DataSource = bs;

 

 This 2 filters work OK separately, but I also need have both filters active together..

I am trying to make a combination of these 2 filters 

 

bs.Filter = "[State] Like '%" + FilterState.Text + "%'" AND "[Country] Like '%" + FilterCountry.Text + "%'"; 

 

 But, the line above is not working. How can I do it? Or must I have a totally different approach to ahve multiple filters
