The default behavior of the sorting method is relying on the data source for the grid and by default sorting is done based on the value members present in the data source and not based on display member. It can be achieved by adding the foreign key reference to the grid. The code for foreign key column can be added to the view of the data table so that the sort behavior can be redirected to use foreign key column linked to the combo box column when the user sorts combo box column.
Moreover here we have provided the simple sample. In this sample, we have explained the SortByDisplayMember by ComboBox column and comment out the process for each step.
