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": protected override void OnIsDirtyChanged(bool DirtyShouldBe)
{
if (this.isDirty && this.EditingState == BusinessEditingState.Idle)
this.Save();
base.OnIsDirtyChanged(DirtyShouldBe);
} however, this throws a stackoverflow exception. So, what is the appropriate way to handle this ? thanks.

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)
