checkbox control passing null value in datagridview

I have a checkbox in a datagridview and it is passing a null value instead of a false/0 when user doesn't click on it. How can I change it, so it passes a value. I already tried passing values explicityly through the bounddatacolumn properties in the datagridview...

Have you modified the DataGridViewCheckBoxCell.ThreeState property

Unfortunately none of the solutions suggested worked. Here is what worked for me:
The value passed is not even null. there fore I had to convert to a string and then compare its length..

private void DGView_RowValidating(object sender, DataGridViewCellCancelEventArgs e)
{
int RowEdited = e.RowIndex;
if (DGView["MfgColumn",
RowEdited].Value.ToString().Length <= 0)
DGView["MfgColumn", RowEdited].Value = 0;
}

It's already set to False..I checked from the designer.

How are you getting the values This works for me

Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim chkCol As New DataGridViewCheckBoxColumn
chkCol.Name = "CheckMe"
chkCol.HeaderText = "Check Me"
DataGridView1.Columns.Add(chkCol)
DataGridView1.AllowUserToAddRows = False
DataGridView1.RowCount = 5
For Each r As DataGridViewRow In DataGridView1.Rows
Dim val As Boolean
val = CBool(r.Cells(0).Value)
Trace.WriteLine(val)
Next
End Sub

End Class
