dropdownlist as templatefield needs outer gridview's row value as select parameter

[Managed Code]

Hello,
I have a status and definition table. The status table's current
status field relates the ID field of the definition table. I am trying
to retrieve the definitions that are associated only with the master_id
for the status table's current status. After having some trouble
databinding I found a solution using a hidden label to save the value I
need for my select parameter. The error I am receiving is

'ddlStatus' has a SelectedValue which is invalid because it does not
exist in the list of items.
Parameter name: value

Any hints on where to go from here would be appreciated.

Thanks, MC
