Hi,

i have an issue with my maintanance forms allways starting with the maintanance toolstrip showing the save and undo buttons enabled and the navigate buttons disabled.

i guess this is because automations on the form cause the bo to become dirty. ?

so within the bo, i tried this, to set it "undirty":

however, this throws a stackoverflow exception.

So, what is the appropriate way to handle this ?

thanks.

You created an infinite loop.  The first thing that you need to figure out is why the BO is becoming dirty.  Something is changing a value.  One thing I would do is handle the IsDirtyChanged event, put a break point, then look at the call stack to determine if I could see what is changing.
