1. There is no way to do that directly. Once you have your data in the grid, you can loop through the rows and check each box like this:

   foreach (DataGridViewRow row in dataGridView1.Rows)
   {
       row.Cells[CheckBoxColumn1.Name].Value = true;
   }
   

2. The Click event might look something like this:

   private void button1_Click(object sender, EventArgs e)
   {
       List rows_with_checked_column = new List();
       foreach (DataGridViewRow row in dataGridView1.Rows)
       {
           if (Convert.ToBoolean(row.Cells[CheckBoxColumn1.Name].Value) == true)
           {
               rows_with_checked_column.Add(row);
           }
       }
       // Do what you want with the check rows
   }
