How Do I: Populate the headers in a DataGridView?

Hello: I have a DataGridView that does not have any columns defined. I would like to add the columns and headers at run time. Can someone tell me the correct format of the line?

Hi Below lines will add 2 columns with behaviours defined in CellTemplate. Error normally committing is that CellTemplate not assigning to the specified Column. DataGridViewColumn col; DataGridViewCell cell; //Creation of 1st column col = new DataGridViewColumn (); col.HeaderText = Column1 ; cell = new DataGridViewTextBoxCell (); cell.Style.BackColor = Color .Blue; col.CellTemplate = cell; dataGridView1.Columns.Add(col); //Creation of 2nd Column col = new DataGridViewColumn (); col.HeaderText = Column2 ; cell = new DataGridViewTextBoxCell (); cell.Style.BackColor = Color .Red; col.CellTemplate = cell; dataGridView1.Columns.Add(col);
