FIX: Add Method of the DataRowCollection Does Not Reflect Changes in XmlDataDocument View (320849)

MORE INFORMATION

• The following adds the specified DataRow to the DataRowCollection object:

  Overloads Public Sub Add(DataRow)
  					

• The following creates a row by using specified values and adds it to the DataRowCollection. The values are passed as an object array:

  Overloads Overridable Public Function Add(Object()) As DataRow
  					

Steps to Reproduce the Behavior

1. Open a new Microsoft Visual Basic .NET Windows Application project. By default, Form1 is added to the application.
2. Import the following namespace:

   imports System.XML
   					

3. Paste the following code in the Form1 Load event:

           'Create a dataset. 
           Dim ds As New DataSet("simpleexample")
   
           'Add a single columned table to it. 
           ds.Tables.Add("table1")
           Dim c As New DataColumn("col1")
           c.DataType = GetType(System.String)
           ds.Tables("table1").Columns.Add()
   
           'Create an xmldatadocument synchronized with the dataset. 
           Dim xd As New XmlDataDocument(ds)
   
           'Add a record to the table using an object array. 
           Dim vals(0) As Object
           vals(0) = "Add This Column"
           ds.Tables("table1").Rows.Add(vals)
   
   
           'Add a record to the table using DataRow. 
           'Dim dr As DataRow
           'dr = ds.Tables("table1").NewRow
           'dr(0) = "Add This Column"
           'ds.Tables("table1").Rows.Add(dr)
   
           ds.AcceptChanges()
           MsgBox(xd.OuterXml, , "Outer XML of XMLDataDocument")
           MsgBox(ds.Tables("Table1").Rows.Count, , "Number of Rows In DataSet")
   
           'Save the dataset and xmldatadocument and still do not see the added row in XMLDataDocument. 
           xd.Save("firstdatadocument.xml")
   
           ' The added row does show up when doing WriteXml of Dataset. 
           ds.WriteXml("simpleexample.xml")
   
   					

4. Run the application. The first message box shows the OuterXML of XMLDataDocument, which does not contain the newly-added row. The second message box shows the number of rows in the DataTable in DataSet, which in this case is 1.
   
   
5. Comment the lines that use Object Array to add rows, and then uncomment the lines that use DataRow to add a new row. Run the application again. This shows the correct behavior. The first message box shows the newly-added row, and the second message box shows the number of rows in the DataTable, which in this case is 1.
