Adding new columns to a Winforms DataGridView via code

Question

I\'m trying to add N number of columns for each days of a given month:

var daysCount = DateTime.DaysInMonth(DateTime.Now.Year, month);

for (int i = 1; i <= d         


        

Answer 1

set your table and add needed columns. then use:

var daysCount = DateTime.DaysInMonth(DateTime.Now.Year, 1);

for (int i = 0; i <= daysCount; i++)
        {
          i = dataGridView1.Rows.Add(new DataGridViewRow());


                        dataGridView1.Rows[i].Cells["YourNameCell"].Value = i.ToString();

       }

Frist row is 0, not 1. probabily your error are these.
