Delete Data From GridView And ObjectDataSource

The function that is supposed to delete a row, is not working. The function is called, and the windows is refreshed, but the row is not deleted.
Can anyone see anything wrong with this code:

public static void DeleteBlog(int original_BlogID)
{
string insertCommand = "DELETE FROM Blog WHERE BlogID = @BlogID";
SqlConnection myConnection = new SqlConnection(Blog.ConnectionString);
SqlCommand command = new SqlCommand(insertCommand, myConnection);

command.Parameters.Add(new SqlParameter("@BlogID", original_BlogID));

myConnection.Open();
command.ExecuteNonQuery();
myConnection.Close();
}
