Hello
The problem is that when the RecordSet is in changing ,after oda.fill,the All rows int DataSet.tables[0] will lose changing state

for example,there a ADOr.xml file
<xml xmlns:s='uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882
xmlns:dt='uuid:C2F41010-65B3-11d1-A29F-00AA00C14882
xmlns:rs='urn:schemas-microsoft-com:rowset
xmlns:z='#RowsetSchema'><s:Schema id='RowsetSchema'><s:ElementType name='row' content='eltOnly' rs:CommandTimeout='30
rs:updatable='true'><s:AttributeType name='CODE_NAME' rs:number='1' rs:writeunknown='true
rs:basecatalog='YSWebTest' rs:basetable='T_CODE_MEAN
rs:basecolumn='CODE_NAME' rs:keycolumn='true'><s:datatype dt:type='string' rs:dbtype='str' dt:maxLength='40
rs:maybenull='false'/></s:AttributeType><s:AttributeType name='CODE_DESC' rs:number='2' rs:nullable='true
rs:writeunknown='true' rs:basecatalog='YSWebTest' rs:basetable='T_CODE_MEAN
rs:basecolumn='CODE_DESC'><s:datatype dt:type='string' rs:dbtype='str' dt:maxLength='80'/></s:AttributeType><s:AttributeType name='CANMODIFY' rs:number='3' rs:nullable='true
rs:writeunknown='true' rs:basecatalog='YSWebTest' rs:basetable='T_CODE_MEAN
rs:basecolumn='CANMODIFY'><s:datatype dt:type='string' rs:dbtype='str' dt:maxLength='1'/></s:AttributeType><s:AttributeType name='REMARKS' rs:number='4' rs:nullable='true
rs:writeunknown='true' rs:basecatalog='YSWebTest' rs:basetable='T_CODE_MEAN
rs:basecolumn='REMARKS'><s:datatype dt:type='string' rs:dbtype='str' dt:maxLength='1000'/></s:AttributeType><s:extends type='rs:rowbase'/></s:ElementType></s:Schema><rs:data><z:row CODE_NAME='9' CODE_DESC='9' CANMODIFY='9' REMARKS='9'/><rs:insert><z:row CODE_NAME='8' CODE_DESC='8' CANMODIFY='8' REMARKS='8'/></rs:insert></rs:data></xml

in this XML Data ,there a new row in insert state (rs:insert)
then ,i read xml into a new ADO RecoredSet and fill into then DataSet ,like this code
OleDbDataAdapter oda = new OleDbDataAdapter ()
ADODB.Recordset adoRS = new ADODB.Recordset()
DataSet ds2 = new DataSet()
adoRS.Open(@"d:\ADOr.xml","Provider=MSPersist;",CursorTypeEnum.adOpenDynamic,LockTypeEnum.adLockOptimistic, 1)
oda.Fill (ds2,adoRS,"T_CODE_MEAN")

after fill,the rows in ds2.tables[0] has lose state
//ds2.WriteXml (StrWriter ,XmlWriteMode.DiffGram)
//dsXML = StrWriter.ToString()
//MessageBox.Show (dsXML)

if anyone could help me
THX!

I am not really sure why you are using the RecordSet here. Based on your
code snippit I do not see any reason for it.

Try setting the AcceptChangesDuringFill property to false before you fill
the dataset.

This property marks the rows as new so any changes are not lost and will
allow you to update a database based on the inserted data.
