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.

Answer 1

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.
