The same issue as described in
https://bugzilla.novell.com/show_bug.cgi?id=595568 happens with custom
BoundField in edit mode with overridden InitializeDataCell() and a TextBox.

Reproducible: Always

Steps to Reproduce:
1. Add GridView to Page markup.
2. Set AutoGenerateColumns property to False.
3. Create a derived class from BoundField.
4. Override InitializeDataCell().
5. Create a TextBox in InitializeDataCell().
6. Add newly created TextBox the Controls collection of the cell.
7. Attach OnDataBinding() event handler to the newly created TextBox.
8. During OnInit() event of the GridView create instance of the custom field.
9. Add custom field to the Columns collection of the GridView.
10. During Page_Load DataBind the GridView.
Actual Results:  
System.InvalidCastException: Cannot cast from source type to destination type.
