I am new to WPF and Infragistics Controls. I am trying to accomplish a
seemly simple task. use Xamdatagrid to display a collection of data records
retrieved from database.Besides the columns from the data records, I want an
additional unbounded column to contain a checkbox. I am having a really
hard time to get the databinding to work. I have spend 2 days to look up
examples and tutorials but none are complete or easy to understand(for me at
least). If I just set the datasource in the code behind and set
autogeneratecolumn to true, it works ok. But that's not what I need, I need
to control which field is visible in the grid and also add the checkbox
column. When I run the code below, I can see data is available but the
datagrid is blank. I think it's because I didn't specify binding of the
columns between the grid and datasource. But what's the syntax to do this
explicitly for XAMDatagrid? Please help me to see what I have done wrong in
code below and what I haven't done to get the desired behavior. I have no
BAOZI but sincere appreciation...

collection for infragistics xamdatagrid
for syntax google "infragistics binding object/s" | d***m

collection) to DataSource not DataContext.
DataContext="{Binding Source={StaticResource POAObjs}}"
