Forms Data Controls :: Read The Values From GridView?

Snap shot of asp code

<Columns>
<asp:BoundField DataField="DeptarmentID" HeaderText="DeptarmentID" ReadOnly="true" />
<asp:BoundField DataField="DepartmentCode" HeaderText="DepartmentCode" />
<asp:BoundField DataField="DepartmentName" HeaderText="DepartmentName" />
<asp:BoundField DataField="Active" HeaderText="Active" />
</Columns>

snap shot of page behind

protected void GridViewDept_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
GridViewRow row = GridViewDept.Rows[GridViewDept.EditIndex];

string code = ((TextBox)(row.Cells[2].Controls[0])).Text;
string name = ((TextBox)(row.Cells[3].Controls[0])).Text;
bool active =((TextBox)(row.Cells[4].Controls[0])).Text=="True"?true:false;
//bool active = ((CheckBox)(row.Cells[4].Controls[0])).Checked;
int id = System.Convert.ToInt32(row.Cells[1].Controls[0]);
}

I get error on the last line stating out of index error, how do get the value which is not set editable in the gridview
