assume i created a user control which contains a datagridview element.
assume i want to derive several custom controls from that control and i want
to edit the properties of the dgv in vs05 at design time (binding
datasources, editing columns and something like that).

When I try to open my .net2 windows form code file in the vs2005 designer, I
get the error message "Duplicate component name
'iDDataGridViewTextBoxColumn'. Component names must be unique and
case-insensitive."
