Using typed datasets and ran into an issue with nulls. Been able to annotate the dataset and work-around the issue. The annotations work properly in all cases but are NOT reflected in the GetXml. The values clearly are there when referenced with the dot notation. But are never there with the GetXml method. I expected to get the values I specified using nullValue="x", instead I do NOT see the column at all. Also, the GetXmlSchema method returns the xsd without any of my changes. <BR><BR>Needed to get the xml as a string WITH the annotations. Also, needed to get the xmlschema with the annotations as I&#039;m passing this back to a legacy application that expects ALL columns to be in the xml.<BR><BR>Any help would be greatly appreciated. Thanks!
