Insert data in datagridview gives exception

Question

I want to use datagridview for show some data(information) to user. My datagridview has 4 column. When I use this code

private void sfactor_Load(object sender, EventArgs e)
{
        dataGridView1.Rows[0].Cells[0].Value = "book";
        dataGridView1.Rows[1].Cells[0].Value = "pen";
        dataGridView1.Rows[2].Cells[0].Value = "x";
        dataGridView1.Rows[3].Cells[0].Value = "y";
        dataGridView1.Rows[4].Cells[0].Value = "z";
}

I want to show this info just in column[0]. When program run, it has exception:

Index was out of range.
Must be non-negative and less than the size of the collection.
Parameter name: index

I know why but I don't know how I can solve it. Now I need your help and your experience. I wait for your answer.

You want to create a datatable and fill that up.

Then you can use the datasource property of your datagridview to bind your datatable to the datagridview.

You need to create the rows before assigning values. There's an overload which lets you create and set values at the same time:

    dataGridView1.Rows.Add("book");
    dataGridView1.Rows.Add("pen");
    dataGridView1.Rows.Add("x");
    dataGridView1.Rows.Add("y");
    dataGridView1.Rows.Add("z");

@mahnaz Once you've added the rows you can address them by index.
