[RESOLVED] Get data from DataGridView

Hello everyone.I have a problem with reading data from DataGridView to array. Use code:

int[,] n = new int[3,19];

for (int i = 1; i <= StartDataView.Rows.Count; i++)
{
for (int j = 1; j <= StartDataView.Columns.Count; j++)
{
n[i - 1, j - 1] = (int)StartDataView.Rows[i].Cells[j].Value;
}
}

but all values results is "null";in this case:

n[i - 1, j - 1] = int.Parse(StartDataView.Rows[i].Cells[j].Value.ToString());

get "0";

What I do wrong?

At first please use codetags,( thats what you do wrong here in this forum :D ) So please edit your post. Without codetags code losts formatting.
we do not know if your grid contains integers. Are you sure ? maybe it contains strings, so what contains your grid. Please show a screenshot maybe so we can see

Code:

int[,] n = new int[3, 19];

            for (int i = 0; i < (StartDataView.Rows.Count - 1); i++)
            {
                for (int j = 0; j < StartDataView.Columns.Count; j++)
                {
                    try
                    {
                        n[i, j] = int.Parse(this.StartDataView.Rows[i].Cells[j].Value.ToString());
                    }
                    catch (Exception Ee)
                    { //get exception of "null"
                        MessageBox.Show(Ee.ToString());
                    }
                }
            }

JonnyPoet,thanks you for helping me,not only in understanding of my program mistakes...

Above the code, I have a StringGridView ,it's bind with BindingSource,user may enter the numbers(with int type) ...but when I debugging ,value is "NULL" ,add some attachments...

I tested your code in the added project and as you will see it works.
So the problem must be elsewhere maybe in the databinding itself ?

Thank you very much JonnyPoet,your example helps me to understand my mistakes..i have only binding source in my project,but when i do like in yor example it works!!
