I generally try not to use 3rd party controls unless I really have to.
I now have a large datagrid that needs very complex column filtering and so I've decided to use the XamGrid from Infragistics (since I have a license for it I might as well use it).
However I'm having a problem with the columns.
The following key(s) do not correspond with the DataSource: "Supplier.CompanyName". If you'd like to add additional columns, please use the UnboundColumn type.
What do I need to be aware of when using the XamGrid?
