چون در عمل به ندرت از movePrev و امثال اینها استفاده می شود این موارد از ADO.NET حذف شده اند . واقعا شما چه استفاده ی خاصی از این متد در دیتاگرید می خواهید داشته باشید؟
Say goodbye
In classic ADO, the Recordset was the primary method of accessing data. It was as simple as executing a query, and a Recordset was created with the requested columns from one or more tables. In cases where multiple rows (records) were returned, navigation was accomplished through the use of the move, moveNext, movePrevious, moveLast, or moveFirst methods. Useless, of course, since a forward-only cursor was used, in which case only moveNext, moveLast, and move (if moving forward) are permitted.
In ADO.NET, Recordsets are gone and cursors exist in concept only. They have been replaced by data classes that provide the same functionality. For example, most of the cursors that I used in classic ADO were forward-only, read-only, because I’m one of those developers who believes that it is best to get the input/output over with as soon as possible. With the advent of ADO.NET, instead of the forward-only, read-only cursor, a DataReader object provides the same functionality.
