DataSet rows being deleted, but after the update , the sql database is not updated. The de

Stepping thru the code with the debugger shows the dataset rows being deleted.

After executing the code, and getting to the page presentation. Then I stop the debug and start the

page creation process again ( Page_Load ). The database still has the original deleted dataset rows.

Adding rows works, then updating works fine, but deleting rows, does not seem to work.

The dataset is configured to send the DataSet updates to the database. Use the standard wizard to create the dataSet.

cDependChildTA.Fill(cDependChildDs._ClientDependentChild, UserId);

rowCountDb = cDependChildDs._ClientDependentChild.Count;

for (row = 0; row < rowCountDb; row++)
{

dr_dependentChild = cDependChildDs._ClientDependentChild.Rows[0];
dr_dependentChild.Delete();


//cDependChildDs._ClientDependentChild.Rows.RemoveAt(0);

//cDependChildDs._ClientDependentChild.Rows.Remove(0);
/* update the Client Process Table Adapter*/
// cDependChildTA.Update(cDependChildDs._ClientDependentChild);
// cDependChildTA.Update(cDependChildDs._ClientDependentChild);

}

/* zero rows in the DataSet at this point */

/* update the Child Table Adapter */
cDependChildTA.Update(cDependChildDs._ClientDependentChild);

Hi,

You should use AcceptChanges method after using delete in order to update the data. The following link may be helpful to you.

Thanks.

DataRow syntax

command.CommandText = "SELECT UserName from Users WHERE UserID = " = userID

Executing this command returns one table with one column with one row. What is the syntax for getting that value into a variable? I can get the information into a dataSet but I can't get it out. Should I be using a dataSet for this operation?

The rest of the code so far:

SqlDataAdapter dataAdapter =newSqlDataAdapter();

dataAdapter.SelectCommand = command;

dataAdapter.TableMappings.Add("Table","Users");

dataSet =newDataSet();

dataAdapter.Fill(dataSet);

Using that code, your data would be in dataSet.tables[0].rows[0][0].

If that's always just returning one value, you might want to look into using ExecuteScalar instead of the adapter and dataset.

You can just use executeScalar method of SQl command below is example from VB.Net help for scalar modified a little:

Public Function AddProductCategory( _ ByVal UserID As Integer, ByVal connString As String) As Integer Dim Username As string = "" Dim sql As String = "SELECT UserName from Users WHERE UserID = @.USERID" Using conn As New SqlConnection(connString) Dim cmd As New SqlCommand(sql, conn) cmd.Parameters.Add("@.USERID", SqlDbType.Int) cmd.Parameters("@.USERID").Value = newName Try conn.Open() userName = Convert.ToInt32(cmd.ExecuteScalar()) Catch ex As Exception Console.WriteLine(ex.Message) End Try End Using Return newProdIDEnd Function

Thanks

Got it working ... thank you for your help!

It's only populated for certain security related events. It won't be
populated for events like Batch Completed or SP Completed. When I load a
trace into a table I tend to have an auxillary table with the databaseid +
name and then create a view to look at the trace so I get the database name.
I do a similar thing with the Event column (you can find the names for the
eventid's in BOL)
