Go through the datagrid and store all of the data that you want to update in arrays or the like. Sql server has a bit datatype and you can set it to 0 if the checkbox is off or 1 if it is checked. Once you collect all the data pass it to your data layer for a sql update

You can use the DataGrid object to iterate through its cells/controls. For example, using a nested loop you can do:

myDG.Items[index1].Cells[index2].Controls[0]

Edit: It depends on the input controls you have in the columns because you have to cast them. Say you have a datagrid with 10 columns and TextBoxes in all columns except the last, which is CheckBox, you would do:

CheckBox cb = null;
TextBox tb = null;
List myList = new List();
for(int row = 0; row < myDG.Items.Count; row++)
{
  for(int col = 0; col < myDG.Columns.Count; col++)
  {
    if(col < 9){
      tb = myDG.Items[row].Cells[col].Controls[0] as TextBox;
      myList.Add(tb.Text);
    }
    else{
      cb = myDG.Items[row].Cells[col].Controls[0] as CheckBox;
      myList.Add(((cb.Checked) ? "1" : "0"));
    }
  }
}

You could use a 2D array/list to store if you wanted too. HTH
