DevExpress Gridview can't show data

Question

I have this code :

private void frmWeld_Load(object sender, EventArgs e)
{
    List<Weld> lst = _weldRepository.Get().ToList();
    gridControl.DataSource = new BindingList<Weld>(lst) { AllowNew = true };
}

I want to load my data into devExpressGridView

As you can see my data is loaded but the gridview can't show the data and my break point doesn't pass from gridControl.DataSource = new BindingList<Weld>(lst) { AllowNew = true} and my program remains with this state. Why?

I just add new column to my gridview after this the problems occurreded. I use entity framework ,when i change the database my application creates a new database using code first and after that my data is lost but the problem that i said is solved.

if you just assign lst directly to the data source, what would happen? — woodykiddy
I said no error happens just the gridview doesn't show ant data ,something like stopped — Mehrdad Ghaffari

Since your code is executing in Load event, add ForceInitialize() to your code.

private void frmWeld_Load(object sender, EventArgs e) 
{
  // your previous code
  gridControl.ForceInitialize(); <- add this line
}
