Has Dataset Changed?Hello,
I have a form where I want to only enable a save button when something has changed in the dataset. Currently I'm checking current values against original values everytime a value is changed to enable/disable the save button. Is there a way of telling if a dataset has been changed (ds property?) other than using this method? Any help greatly appreciated! Thanks in advance Mark,

No, I don't believe it is that smart. Kerry Moorman Show quoteHide quote "za***@construction-imaging.com" wrote: > > > I wonder if the DataSet class is "smart" enough to set this property > off if a changed value is changed back to the original value? > Kerry,
What do you mean with set back, if you mean set back by hand to the original values, than it will forever be a question if that was a change or not, however if it is using the methods Reject changes or accept changes, than it would do that. (Even it it has been a datarow that was changed) I hope this gives an idea, Cor <za***@construction-imaging.com> schreef in bericht Show quoteHide quote news:1156190452.936603.319310@m73g2000cwd.googlegroups.com... > > Kerry Moorman wrote: >> Mark, >> >> If ds.HasChanges Then ... > > I wonder if the DataSet class is "smart" enough to set this property > off if a changed value is changed back to the original value? > >> >> Kerry Moorman >> >> >> "Mark" wrote: >> >> > Hello, >> > >> > I have a form where I want to only enable a save button when something >> > has >> > changed in the dataset.
