Why does the code stop executing after filling the dataset?

Question

C++ / C#

Good afternoon.

private void invoiceItemEditForm_Load(object sender, EventArgs e)
        {
            itemsBindingSource.Sort = "name ASC";  
            this.itemsTableAdapter.FillByWithProducerName(this.e926595l_skladDataSet.items);
            invoiceItemComboBox.SelectedValue = itemID;
            this.unitsTableAdapter.Fill(this.e926595l_skladDataSet.units);
            unitscomboBox.SelectedValue = unitID;
        }

After the line

this.itemsTableAdapter.FillByWithProducerName(this.e926595l_skladDataSet.items);

the code is not executed. No errors found. What could be the problem?

Answer 1

only two options:
1) wrap the entire block of this code directly in Try / Catch and put a breakpoint (or logs) on catch. The message will make it clear what happened.
2) Run with a debugger. Wait until it freezes. Press "Break All" aka pause. Select Debug -> Windows - Threads from the menu. In the Threads window, search and browse to find the one that hangs on the invoiceItemEditForm_Load and see what it does / waits for. Optionally, you can unpause, and click again and see if this thread has progressed. Maybe he does not wait, but does endless work.
