C# WinForms: Adding rows to a dataGridView

Question

I've just started to use dataGridView, and some things seem strange to me:

when there is a Columns property, in which you can add columns, why is there not a Rows property? It seems you can only add rows programmatically. Or am I wrong?
the 'star' icon to the left of the first row, can't it be removed?
is it possible to disable sorting? I mean when you click on a column, the "sorting-arrow" appears, suggesting that the cells would be sorted.

If it is only possible to add rows programmatically, I have this question:

I need a dataGridView with 1 column and x rows. How to do this the quickest and easiest way? The cells will be filled at runtime, programmatically.

update: About disabling sorting, I found out myself: there is a property to change this if you open the (Collections) of the columns.

You can add Rows by calling dataGridView1.Rows.Add();. For multiple rows there is an overload for the same available. dataGridView1.Rows.Add(5);

Now to fill the dataGridView1 rows you can either assign a DataSource and set the DataPropertyName for the Column. Else loop through and fill the data cell wise like dataGridView1[columnindex,rowindex].Value =something

The star icon shows the current row which is being edited, you can choose to hide that cell by setting the RowHeadersVisible to false.

Thanks, so I guess it's only possible to add rows programmatically. Ok, I have added 4 rows, each with a different HeaderCell value. When I start the program, the names/values are not totally visible, but I can enlarge the width of that row (I'm just calling it a row although its index is actually -1) manually. Can this be done in code? I've tried various AutoSizeColumnsModes, but it doesn't seem to be doing the trick.

You mean the width of the column? Rows don't have widths. Setting width can definitely be done in code. dataGridView1.Columns[index].Width = value

@harlam357, this would work if the index weren't actually -1. You know, the width of the "column" I need to change is the leftmost column, not the first column with cells beneath.
