I have to change the value of a categorical field from "Draft" to "Approved" of a single record the moment the user clicks on the save button after he's done writing\editing the selected record.

Which event should I use to handle this case?

I think I have to handle this on the datasource level, but there are a lot of apparently similar events I could use, which eventhandler should I choose?

-OnCreated

-OnCreating

-OnValidatedWrite

-OnWritten

I think it must one of these but I can't tell the diffrence,which one is closer to the "On Save" event?

OnWritten is when record actually saved.

OnValidatedWrite after validation but before save

OnCreating and OnCreated is about creation but not save.

Thank you very much.

So which one is triggered by the save action? Should I use the OnWritten?

Yes. If you want to do something after record is saved on the form.

I think it would be better to use the OnWriting event, then you let the framework write it to the DB, without the need to call the update() method in your code.

Here is an example:

[FormDataSourceEventHandler(formDataSourceStr(CustTable, CustTable), FormDataSourceEventType::Writing)] public static void CustTable_OnWriting(FormDataSource sender, FormDataSourceEventArgs e) { CustTable custTable = sender.cursor(); custTable.Blocked = CustVendorBlocked::All; }

Note: OnWriting would be like placing your code before the super() of the DS write() method, and OnWritten would be like placing it after the super() call.

It can be done on either event but better to do onValidatedWrite once validations are done you can set field value to approved and it will save it with other changes once record is saved

Hi Fabio,

Is it implemented via initValue() on the form?

Then I think you can modify your field values with the onCreated event handler.

Here's an example:

[FormDataSourceEventHandler(formDataSourceStr(EcoResAttribute, EcoResAttribute), FormDataSourceEventType::Created)] public static void EcoResAttribute_OnCreated(FormDataSource sender, FormDataSourceEventArgs e) { FormRun formRun = sender.formRun(); EcoResAttribute ecoResAttribute = sender.cursor(); ; if (formRun.args().parmEnumType() && formRun.args().parmEnumType() == enumNum(EcoResAttributeModifier) && formRun.args().parmEnum() == EcoResAttributeModifier::MyDirParty) { ecoResAttribute.AttributeModifier = EcoResAttributeModifier::MyDirParty; } }
