Question

private void ShowIterationSelection()
{
    IterationForm iterationForm = new IterationForm(lblProjectID.Text);
    iterationForm.ShowDialog();
}

When I show the dialog it displays a list of iterations associated with the project using the ProjectID:

public partial class IterationForm : Form
{
    public IterationForm(string projectID)
    {
        InitializeComponent();
        LoadIterationsForProject(projectID);
    }

    private void LoadIterationsForProject(string projectID)
    {
        IterationRepository iterationRepo = new IterationRepository();
        Int64 ID = Convert.ToInt64(projectID);
        dgvIterations.DataSource = iterationRepo.FindAllIterations().Where(i => i.IDProject == ID).Select(i => new { Codigo = i.ID, Descripcion = i.Description, Inicio = i.StartDate, Fin = i.EndDate });
    }
}

My question is, how can I capture the selected value from the datagrid view and pass it my calling form to open another form with the select IterationID?

Thanks for the help.

So maybe something like:

private void ShowIterationSelection()
{
    IterationForm iterationForm = new IterationForm(lblProjectID.Text);
    var result = iterationForm.ShowDialog();
    showTheThing(result); //this uses the iterationID
}

Just create a public property on the iteration form that you can access from your main form.

public partial class IterationForm : Form
{ 
    // set this to the selected object (change to w/e type you need)
    public object SelectedObject{get; private set;}
    public IterationForm(string projectID)
    {
        InitializeComponent();
        LoadIterationsForProject(projectID);
    }

    private void LoadIterationsForProject(string projectID)
    {
        IterationRepository iterationRepo = new IterationRepository();
        Int64 ID = Convert.ToInt64(projectID);
        dgvIterations.DataSource = iterationRepo.FindAllIterations().Where(i => i.IDProject == ID).Select(i => new { Codigo = i.ID, Descripcion = i.Description, Inicio = i.StartDate, Fin = i.EndDate });
    }
}

Then you can do:

private void ShowIterationSelection()
{
    IterationForm iterationForm = new IterationForm(lblProjectID.Text);
    var result = iterationForm.ShowDialog();
    showTheThing(iterationForm.SelectedObject); //this uses the iterationID
}
