Odbc .NET Data Provider problem

I use Microsoft Visual C# .NET in an Microsoft Development Enviroment 2002.

Also, I use the Odbc .NET Data Provider from http://msdn.microsoft.com/downloads.

I want to delete some records from the data source (an EXCEL sheet) but the task throws an exception:

"[Microsoft][ODBC Excel Driver] Deleting data in a linked table is not supported by this ISAM."

I managed to Select, Update and Insert data from/in the Excel sheet but the deletion seems to be a problem.

For deletion I used OdbcDataAdapter as well as OdbcCommand objects. In both cases it throws an exeption:
"[Microsoft][ODBC Excel Driver] Deleting data in a linked table is not supported by this ISAM."

Is this a bug of Odbc .NET DataProvider ?
Can anyone help me, please?
