It appears that the databinding cannot find the value member it is looking for. Can you provide more information? Has the DataSource/DisplayMember/ValueMember been set up for this column by the time you try to enter the grid? Is that datasource properly initialized at this point? Can you upload a sample showing this problem?

the valuemember of a combobox column seems to be case sensitive now :-( the whole dataset ist not case sensitive so why is your combobox column casesensitive???

Our binding support includes support for strongly typed objects using property descriptors which are case sensitive. We do not make a distinction between dataset binding and typed object binding. That is why our implementation is case sensitive.
