Question

I have two tables in my database Department and Faculty . I am populating a datagridview for department list in my winform application . Both of my tables are following

Department

1. Sno (int)
2. Name (varchar(max))
3. Status (bit)
4. Faculty_id (int)

Faculty

1. Sno (int)
2. Name
3. Status

Now come to code i simply drag and drop a datagridview into my form and go to code behind file . In my form’s load method i write following code

        var main = new SRMEntities();
        var departs = main.Department.ToList();
        DepartmentGrid.DataSource = departs;

now when my form load it show like this

Look in faculty column its showing nothing and when we create department we store a faculty id into department . i want to show faculty name here .

Please let me know if you have any question .

Thanks in advance

Answer 1

Here is correct join:

var main = new SRMEntities();
var query = from f in main.Faculty
            join d in main.Department on f.Sno equals d.Faculty.Sno
            select new { d.Sno, d.Name, d.Status, Faculty = f.Name };

DepartmentGrid.DataSource = query.ToList();
