Hi,

 We have a problem when setting the datasource of the wingrid to a bindlinglist of hierarchical business objects. It seems that unless there is data in this binding list for ALL levels of the hierarchy then the grid seems to reset itself and shows ALL columns for that band irrespective of the setting s for the grid in regard to which columns to display. Is there any way around this issue ? Also, it causes us problems even if we want to do something simple like:-

 clear grid

    do some form input

refresh grid i.e. set datasource to bindinglist of business objects (hierarchical, 2 levels) 

If we clear the grid by setting the datasource to null or new bindinglist<business objects> then when we later refesh the grid we are presented with all columns being shown in the grid for the second level data. Is there a workaround for this?

It seems to be if at any point you set the datasource of the grid to a bindinglist that is empty or for which the first entry in the list doesn't contain data for all of the 'child' bands then you are stuffed ie. all columns are shown and you lose all formatting, value lists etc. Is this the case? 

Thanks

Jim
