DataSet DiffGram Question

[John Lee]

Hi,

When I use DataSet.WriteXml(filename, XmlWriteMode.DiffGram), the xml file
contains current values (at <InvDataSet> node) and original value (at
<diffgr:before> node) - this means the original values are stored somewhere
in DataSet, Can someone tell me how can I access those original values from
code?

Thanks very much!

John

Hi John,

You can use AcceptChanges method to update the dataset and then
invoke the dataset's GetChanges method to get a new dataset that consist
by the modified values.
You can get the original value from the old dataset wipe off the modified
values

Hope this helps.
