I have the following definition:
<bfgs:bRadGridViewComboBoxColumn UniqueName="colAccountPeriod"
HeaderText="Account Period"
IsReadOnly="False"
DataMemberBinding="{Binding FK_AccountPeriod, Mode=TwoWay}"
DisplayMemberPath="AccountPeriodEnd"
SelectedValueMemberPath="AccountPeriodKey"
IsSortable="True" />
However, it seems that the sorting sorts by FK_AccountPeriod and not the Display value. Is there a way to change this? I would like the dates in the DisplayMemberPath to be sorted on the header click, not the underlying FK.
Thanks..
