I created a class that holds some event handlers, I added my own condition, and my code is entering my condition.

And based on my condition I want to cancel the inserting, updating, and validateWrite to return false but in event handlers, how?

[FormDataSourceEventHandler(formDataSourceStr(LedgerJournalTransDaily, LedgerJournalTrans), FormDataSourceEventType::ValidatingWrite)]
public static void LedgerJournalTrans_OnValidatingWrite(FormDataSource sender, FormDataSourceEventArgs e)
{
    if(some codition)
    {
        return false and don't insert or update the record
    }
}

--------------------------------------------------------------------------

[DataEventHandler(tableStr(LedgerJournalTrans), DataEventType::Updating)]
public static void LedgerJournalTrans_onUpdating(Common sender, DataEventArgs e)
{

    if(some codition)
    {
        don't update the record
    }
}
--------------------------------------------------------------------------

[DataEventHandler(tableStr(LedgerJournalTrans), DataEventType::Inserting)]
public static void LedgerJournalTrans_onUpdating(Common sender, DataEventArgs e)
{

    if(some codition)
    {
        don't insert the record
    }
}

The easiest way is throwing an exception.

Regarding ValidatingWrite, you can cast e to FormDataSourceCancelEventArgs and call cancel(true).

Martin Dráb thank you for your response, but in case of inserting and updating, which are on a table level, how can I cast the dataEvenArgs e, in a way that I can cancel the operation?

Throw an exception to prevent the record from being inserted or updated.
