Platform :All
Product :C++Builder 1.x
Question:
How can I determine when the current record in a dataset has
changed?
Answer:
Check the DataSource's State property in the OnDataChanged event.
The State property will be set to dsBrowse if the record
position has changed. The following example will display a
message box every time the record position has changed in
MyDataSource:
void __fastcall TForm1::DataSource1DataChange(TSender* Sender, TField* Field)
{
if (DataSet1->State == dsBrowse)
MessageBox(0, "Record Changed", "Message", MB_OK);
}
