title: Get the BindingSource position based on DataTable row
body: <p>I have a datatable that contains the rows of a database table. This table has a primary key formed by 2 columns.</p>
  
  <p>The components are assigned this way: datatable -> bindingsource -> datagridview. What I want is to search a specific row (based on the primary key) to select it on the grid. I cant use the bindingsource.Find method because you only can use one column. </p>
  
  <p>I have access to the datatable, so I do manually search on the datatable, but how can I get bindingsource row position based on the datatable row? Or there is another way to solve this?</p>
  
  <p>Im using Visual Studio 2005, VB.NET.</p>
