I have extended a form to write validation on timesheet delete line in the below event handler:

what should i write to prevent delete if enum value is yes.

[FormControlEventHandler(formControlStr(TSTimesheetEntry, DeleteLine), FormControlEventType::Clicked)]
public static void DeleteLine_OnClicked(FormControl sender, FormControlEventArgs e)
{
   FormDataSource    Table_ds   = sender.formRun().dataSource(formDataSourceStr(form, Table));
        Table record = Table_ds.cursor() as Table;
        if (record.field == NoYes::Yes)
        {

            checkFailed(/PTO line updation is not allowed/);


        }

}

pls suggest.

Hi Ayushii,

I think adding clicked eventHandler for the DeleteLine button won't work here.

It's better to add the validation at table level of TsTimesheetLine.

Add your logic on the ValidateDelete method on the table. You can use COC or event handlers.

Thanks,

Girish S.

Clicked is a wrong event for validation, it's too late there and pressing a button isn't the only way how to delete a record.

Instead, override validateDelete() method of the table or handle its ValidatingDelete event.
