rowstate problems

[Phil Townsend]

I have a datagrid in a windows forms application. The datagrid gets its
data via a web service. Users can modify rows in the datagrid then post
their changes. However, when changes are made the rowstate remains
"Added" for all the rows--those that were modified AND those that were
unchanged. Here is the code I am using to test (dsitems is the
underlying dataset):

private void btnSave_Click(object sender, System.EventArgs e)
{
string res=string.Empty;
foreach(DataRow dr in dsitems.GetChanges().Tables[0].Rows)
{
res+=String.Format("{0}|{1}|{2}\n",
dr["pagetitle"],
dr["pagelocation"],
dr.RowState.ToString()
);
}
lblresults.Text=res;
}

Any ideas as to why the rowstate is always set to "Added" ?

Phil,

Is it possible that the rowset that you receive already has that as the
rowstate? Is it possible that the web service is constructing the data set
and not calling AcceptChanges (since it might create it from scratch and add
the rows manually)?

Hope this helps.
