Form2 Frm2 = new Form2();
public Form1()
{
InitializeComponent();
DataGridViewCheckColumn();
Frm2.newEvent += new FrmCheckbox(Frm2_Event);
}
public void DataGridViewCheckColumn()
{
dataGridView1.ColumnCount = 6;
dataGridView1.AllowUserToAddRows = false;
DataGridViewCheckBoxColumn colCB = new
DataGridViewCheckBoxColumn();
colCB.Name = "chkcol";
colCB.HeaderText = "Select";
colCB.Width = 40;
dataGridView1.Columns.Add(colCB);
dataGridView1.Columns[0].Name = "C0";
dataGridView1.Columns[1].Name = "C1";
