Ok very new to this. I am using Visual Studio 2013. I have 3 tables I am working with from a database the database is called GC_Emp_data, the tables are TrainingCourse, Positions, and then Training_Positions. The training course has a list of all the courses the positions has all positions, and the last table merges the to together via the ID number. So a training course could be in multiple positions. What I wanting to do is Select a Training course via a combo box and then it populate a datagridview that will allow me to see what positions that it's has assigned in the (training_posoition table) and also allow me to add new positions to that table. Not sure where to start and cannot find the right starting point.
