I have a BO in which I edit several records based on the BO.Filter condition, so I do this:





Now when I call the BO.Save() will the Save() method do the following:





I ask because originally the BO may have a couple of thousand records and need to know if the saving speed will be compromized in any way.

When looking at anything on the BO that deals with dirty records, the filter applied is irrelevant as the CurrenDataTable is used instead of the current view.  Your applied filter will be left alone so there will not be any speed issues as the applied filter will be ignored for dirty records.

The Select() is used through ADO.NET on the data table to get any rows that have an added, modified, or deleted row state.  The same logic is taken into account during a save.  So you should not experience any performance issues in this regard.  Just so you know, the current data table is enumerated (not the view) when checking any to see if a row needs to be checked for validation, so the applied filter is ignored there as well.  In short, the save and row checking only looks at rows that have been modified, deleted, or added.

Thanks for the explanation. Now I know I don't have to worry about which BO.Filter is in effect in order to save all modified records.
