MVP

In a win forms application there is a grid view in the UI which should be populated with the details of branch offices of the client. There are about 50 branches. So `GetBranchDetails()` method in the `DataService` class returns a `DataSet` and the `Presenter` class passes that `DataSet` to the UI's `BindData()` method in which the `datasource` property of the grid view is set to the `DataSet` object as shown in the code.

The problem is the `DataService` is not returning a model rather it returns a `DataSet`. Can some one tell me how to use `BranchOffice` model instead of using a `DataSet` here? So that the `Model` should be returned from `DataService` and then the `presenter` will pass that `Model` to UI where the `Model` will be set as the `datasource` to the grid view. Please note that always there will be more than one branch offices!

DataService Class

public DataTable GetBranchDetails()
{
    string selectStatement = "SELECT ID, branch_name + ', ' + branch_add AS Branch,       area, sm, atten_status FROM Branch WHERE Status='Active'";
    using (SqlConnection sqlConnection = new   SqlConnection(db.GetConnectionString))
    using (SqlCommand sqlCommand = new SqlCommand(selectStatement, sqlConnection))
    using (SqlDataAdapter da = new SqlDataAdapter(sqlCommand))
    using (DataSet ds = new DataSet())
    using (DataTable dt = new DataTable())
   {
      ds.Tables.Add(dt);
      sqlConnection.Open();
      da.Fill(dt);
      return dt;
   }
}

Presenter Class

private void _View_ShowBranches(object sender, EventArgs e)
{
    ShowBranches();
}

private void ShowBranches()
{
    var dt = DataService.GetBranchDetails();
    this._View.BindData(dt);
}

View / UI

public partial class frmAttendancePoints : Form, IView
{
    public frmAttendancePoints()
    {
        InitializeComponents();
    }

    public void BindData(DataSet dt)
    {
        dgAttendancePoints.DataSource = dt;
    }
}
