rik,

Did you create a new SqlCommand for your data adapter's SelectCommand?

// Create the SelectCommand.

cmd = new SqlCommand("SELECT * FROM Customers " +
"WHERE Country = @Country AND City = @City", conn);

cmd.Parameters.Add("@Country", SqlDbType.NVarChar, 15);
cmd.Parameters.Add("@City", SqlDbType.NVarChar, 15);

da.SelectCommand = cmd;

yes i did.
and the command type was a stored procedure.


da.SelectCommand.CommandType = CommandType.StoredProcedure;

thanks
rik

rik,

Where are you assigning the newly created SqlCommand to the new SqlDataAdapter? Something like:

da.SelectCommand = cmd;

 

[rbutch]

i thought what i sent you was that.
i basically ripped this right off of the microsoft website:
