Selecting All Rows from a Datagridview

Question

I wonder how I do to select all the Rows of a DataGridView.

Code that I have:

DataGridView.Rows[0].Cells[0].Value.ToString();

Answer 1

Use the method DataGridView.SelectAll to select all lines:

dataGridView1.SelectAll();

To select the rows of a specific column, do so, for example in click one-button:

void Button1Click(object sender, EventArgs e)
{
    dataGridView1.ClearSelection();

    for(int i = 0; i < dataGridView1.RowCount; i++)
        dataGridView1[0, i].Selected = true; // "0" Indica a primeira coluna
}
