How to set Cell value of DataGridViewRow by column name?

Question

In windows forms, I\'m trying to fill a DataGridView manually by inserting DataGridViewRows to it, so my code looks like this:

Data

The problem is that referencing cells by name doesn't work until the row is added to the DataGridView. Internally it uses the DataGridViewRow.DataGridView property to get at the column names, but that property is null until the row is added.

Using C#7.0's local function feature, the code can be made halfway readable.

DataGridViewRow row = new DataGridViewRow();
row.CreateCells(dgvArticles);

DataGridViewCell CellByName(string columnName)
{
    var column = dgvArticles.Columns[columnName];
    if (column == null)
        throw new InvalidOperationException("Unknown column name: " + columnName);
    return row.Cells[column.Index];
}


CellByName("code").Value = product.Id;
CellByName("description").Value = product.Description;
.

dgvArticles.Rows.Add(row);
