Hi,
I want to know how to control the multiple users editing in DA. Suppose records is stored in TDAMemDataTable. How to doing the record of version control? Is it like “Record Lock” if the other want to edit the same record?

Hi,

I can suggest our DA7 sample that does almost the same: Refresh Update Data.zip (5.5 MB)

Hi,

Hi,
I checked the source code that is not meet my expectation. It needs to create a lock field that control the status. I suppose it like MSSQL ROWLOCK feature or using the timestamp to control the version.
