Update a record with ADODataset

Goodmorning
I am using a database in access 2007 and c++ builder 2007. I have a problem and i want some help. I have a dbgrid on my simple application and the user find a record and click on it. When he clicks all the data return to Edit text. Now i want the user to make some changes on edit text (on data) and update the record. I have wrote the above code

[CODE]

Form7->ADODataSet2->Active=true;
Form7->ADODataSet2->Edit();

ADODataSet2->FieldValues["AR_PAROXHSD"]= Edit2->Text ;
ADODataSet2->FieldValues["CUSTOMER_NAMED"]=Edit4->Text;
ADODataSet2->FieldValues["CUSTOMER_SURNAMED"]=Edit5->Text;
ADODataSet2->FieldValues["CUSTOMER_FATHERD"]=Edit6->Text;
ADODataSet2->FieldValues["CUSTOMER_STATHEROD"]=Edit7->Text;
ADODataSet2->FieldValues["CUSTOMER_MOBILED"]=Edit8->Text;
ADODataSet2->FieldValues["CUSTOMER_AAKAT"]=Edit9->Text;
ADODataSet2->FieldValues["CUSTOMER_ADDRESSD"]=Edit10->Text;
ADODataSet2->FieldValues["CUSTOMER_CITYD"]=Edit11->Text;
ADODataSet2->FieldValues["CUSTOMER_ZIPD"]=Edit12->Text;

ADODataSet2->Post();
[CODE]
The problem is that when i push the update button it changes my first row of databse and not the one that user select. I need to add something on code so to move in record that the user choose and then edit and post

You'd better ask this in some Borland forums. As BC++/Delphi adodataset implementation is very Borland specific, and your question has nothing to do neither with C++ nor WinAPI.
