Link DataGridView With Other VB Features?

I even have it set up so I can filter through the DataGridView by sorting though a specific company in the database. However, now I want to link specific cells from the DataGridView to other VB features such as a text box and check box. I am a bit lost as to the coding. In the DataGridView, there are numerous columns that contain a check box and I need them to correlate to actual check boxes I have in the form. I can do it through binding the check box on the form to the data source and it works but if I run a filter or sort through the company, the check boxes from the DataGridView no longer carry over to the actual check box on the page.
