I have a radGrid that is bound to a custom class called "BillingItem".
The user copies/pastes data from Excel into the radGrid, which then does some validation for each cell in the PastingCellClipboardContent Event that calls an Async WCF Service to ensure the data being is clean.
The Column "ProductLine" then has it's ItemSource set to a List of ProductLine objects returned from another Async WCF Call.
After this all takes place, the GridViewComboBoxColumn displays blank for every Row. However, when the field is clicked for any Row, the comboBox shows the correct available values.
Why is this showing blank until it is clicked?
