I want to create a filter template that works like the foreign key filter template but that isn't for a foreign key column but instead just a string column. The dropdown should be populated with the distinct values in the column. I'm having trouble accessing the values in the column from the new template though. I tried using GetColumnValuesFromRoute in Page_Init of the template but it's not returning anything in items below.
Dim items As IDictionary(Of String, Object)
items = Column.Table.GetColumnValuesFromRoute(Context)
I'm using VS2010 and .Net 4.0.
