Hi every body

I have a table of courses and another for students.
And I need to fill a grid view with the following information

1- course ID
2- course name
3- number of students in each course

Without repeating the course name, means each course in a single row.

Note: I am using a query builder.

than you

More information is required. There ought to be a table to provide a many-to-many relationship between the students and courses.

I have the three tables, what I am really concerned about is how to calculate the number of students in the StudentCourses table for each course using the query builder or a C# code.
thank you
