I'm using a function to delete all data from 9 Tables of my database using typed dataset and adaptermanager.UpdateAll.
The update fails with a DBConcurrencyException, because one table
throws an RowNotInTableException.
All I'm doing is Fill all my tables and then delete the rows. There is no other process working on the database. How can the row get detached?
Is there a way to get the primary key of the row that is producing the problem?
My Code (shortened):
--- 6 other fills before
FillDataTable("parameters");
List<AzureDataSet.parametersRow> parRows = (from p in azureDataSet.parameters where p.ID != "undefined" select p).ToList();
foreach (AzureDataSet.parametersRow item in parRows)
item.Delete();
FillDataTable("definitions");
List<AzureDataSet.definitionsRow> defRows = (from sd in azureDataSet.definitions where sd.hashPK != "undefined" select sd).ToList();
foreach (AzureDataSet.definitionsRow item in defRows)
item.Delete();
--- definitions table produces the error, there is only one more table to fill left
AzureDataSetTableAdapters.TableAdapterManager adapterManager = new AzureDataSetTableAdapters.TableAdapterManager();
adapterManager.parametersTableAdapter = new AzureDataSetTableAdapters.parametersTableAdapter();
adapterManager.definitionsTableAdapter = new AzureDataSetTableAdapters.definitionsTableAdapter();
adapterManager.BackupDataSetBeforeUpdate = true;
retryPolicy.ExecuteAction(() =>
{
adapterManager.UpdateAll(azureDataSet);
});
-- EDIT --
I tested the delete operation outside of the adapterManager. So I called every TableAdapter.Update method separately.
The same table throws the error:

-- EDIT 2: SOLVED --
I could solve my problem, but I have no idea what caused the problem. All I did was opening my DataSet.xsd, open the delete command of the table and save the DataSet again. I changed nothing!
