Crashing when trying to see if my Cell is checked or unchecked

Question

My system clock is 9/16/2014 (Tuesday)

But in code, I'm always jumping to Monday.

DayOfWeek dow = DateTime.Now.DayOfWeek;
int columnNumber = 0;

columnNumber = columnNumber + 0;

foreach ( DataGridViewRow row in dataGridView1.Rows )
{
  switch ( dow )
  {
  case DayOfWeek.Monday:
    columnNumber = 4;
    if (Int32.Parse(row.Cells[columnNumber].Value.ToString()) == 1)
    {
         row.Cells["activeTodayDataGridViewCheckBoxColumn"].Value = true;
    }
    break;

I have a DataGridView

Columns 0—3 are Text
Columns 4—9 are DataGridViewCheckBoxColumn

why dont you check if the cell is not null before checking it is true? — Val Nolav, Sep 16 '14 at 17:38

@EhsanSajjad someone pointed out that it was 2 questions in 1 posting so the code had very small changes but the problem is the same. Crashing on a cell. — software is fun, Sep 17 '14 at 12:34
I updated the code to reflect what I tried. Any help would be appreciated — software is fun, Sep 17 '14 at 13:20

What will IsNewRow do? The data is already loaded on the screen when accessing the contents. – software is fun Sep 17 '14 at 12:35
It's always returning false so we go to the switch and crash – software is fun Sep 17 '14 at 13:16
IsNewRow returns true for the empty row at the bottom of the grid ... it's sometimes important to check because there rows[].Cells[].Value will be null – PrfctByDsgn Sep 17 '14 at 13:44
This is happening on the very first row, 2nd row, third row. If I check the box then uncheck it, it doesn't appear to crash – software is fun Sep 17 '14 at 16:13
