hi, the issue is solved by setting the ClearOnNULL-Property of the DateTime-Picker to false.

the problem has something todo with binding to the datetime-picker control. on the form there are two of thoose. if i unbind them by selecting Business-Object = none in the property editor, the form behaves correctly (bo doesnt get dirty). however off course then they are not bound  i am setting default values to thoose from the bo's SetDefaultValues procedure. however this aint the cause of the problem, because if i comment theese lines out, the bo still gets dirty. the datetime picker controls are set up with following property values: BindableValue = 01.01.1800
BindingField = MyDateTimeField
BindingProperty = Value
BindingUpdateMode = OnPropertyChanged
BusinessObject = MyBO
ClearOnNULL = True
CustomFormat = dd.MM.yyyy HH:mm:ss
Format = Custom
MaxDate = 31.12.9998
MinDate = 01.01.1753
NullDateValue = 01.01.1800
ShowUpDown = True
StripTimeFromValue = False
Value = 01.01.1800

ive put code in the isdirty event to show a messagabox with all original and current fieldvalues of the modified-state row. for every field, the original and current values are the same.

The stack trace begins (at the bottom) with an edit, so you are going to have to look at the data table to determine the field that is changed. You may have to look at the row as well: MyBO.CurrentDataTable.Rows(0).RowState MyBO.CurrentDataTable.Rows(0)("MyField", Original)
MyBO.CurrentDataTable.Rows(0)("MyField", Current)

just put a breakpoint and looked at the stacktrace. whats immediatly happening before the isdirty changed event triggers is that a bo datetime field gets its value for the first datarow in the bo.

hi, ahem. i tried to figure out where it comes from, but no luck thus far. i put Messagebox.Show(Boname.isDirty.ToString()) infront and at the end of every procedure that i added to the bo and the form. it happens after the bo is filled, but where, is not clear. however, i also dont really care about if its dirty at that point or not, because the user hasnt specified to edit or add a row at that time anyways. actually when i press the undo-button on the maintanance-strip after the form appears, everything is how it should be. cant i just tell the maintanance form to only care about the isdirty-state of the bo if in edit or add mode ? 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.
