Updating a table on DB considering changes on a grid in Csharp

Question

I'm filling a Data Grid in C# (WinForms) via a System.Data.DataTable. DataTable is filled from a DB table via ODP.
I have a data navigator in Data Grid for updating, deleting and inserting rows.
I want to use DataTable to commit all changes made in Data Grid to the database.
I have to use OracleDataAdapter but I couldn't figure out how to achieve this.
What kind of a CommandText should I use to achieve all three commands (update, delete, insert)?
The code below didn't work (maybe because CommandText I inserted is not appropriate)
public void ExecuteNonQuery(string commandText, OracleCommand oracleCommand, CommandType commandType, DataTable dataTable)
oracleCommand.CommandText = commandText;
oracleCommand.CommandType = commandType;
try
oracleCommand.Connection = m_Connection;
OracleDataAdapter oracleDataAdapter = new OracleDataAdapter(oracleCommand);
oracleDataAdapter.Update(dataTable);
catch (Exception)
LoggerTrace.Instance.Write(TraceEventType.Error, LoggerTrace.LoggerTraceSource.DatabaseManagerError, "Query could not be executed!");
throw;
}

Hey,
use the update method of the dataadapter object and the adatagrid input object: <adapater>.update(<datagrid>)
but i think you post in the wrong forum.
Use the knowledge base of Microsoft and .Net!
