] | I have a `DataGridView` with several created columns. I've add some rows and they get displayed correctly; however, when I click on a cell, the content disappears.
What am I doing wrong?
The code is as follows:
```

DataGridViewRow row = new DataGridViewRow();
... | Just to extend this question, there's also another way to add a row to a `DataGridView`, especially if the columns are always the same:
```
object[] buffer = new object[5];
List<DataGridViewRow> rows = new List<DataGridViewRow>();
foreach (SaleItem item in this.Invoice.SaleItems)
{
buffer[0] = item.Quantity;
