We must use Event handlers, if you are
using Extension Model Development in AX 7.
1. How we can handle the Datasource fields based on active/selected record, in Event handler method.
[FormDataSourceEventHandler(formDataSourceStr(FormName, DataSource), FormDataSourceEventType::Activated)]
public static void
DataSource_OnActivated(FormDataSource sender, FormDataSourceEventArgs e){
Common common = sender.cursor();
sender.object(fieldNum(DataSource, ProjActivityNumber)).enable(common.ProjId);
}
2. How we can handle the Controls like,
Tab/TabPage/Button etc
[PostHandlerFor(formStr(
LedgerJournalTable), formMethodStr(LedgerJournalTable, init))]
public static void LedgerJournalTable_Post_init(XppPrePostArgs args)
{
FormRun sender = args.getThis();
LedgerJournalType journalType = sender.args().parmEnum();
if (journalType == LedgerJournalType::Assets)
{
sender.control(sender.controlId(formControlStr(LedgerJournalTable, YourControl))).visible (true);
}
}
3. To get new number sequence reference for an existing module.
[PostHandlerFor(formStr(AssetParameters), formMethodStr(AssetParameters, numberSeqPreInit))]
public static void AssetParameters_Post_numberSeqPreInit(XppPrePostArgs args)
{
TmpIdRef tmpIdRef;
NumberSeqScope scope;
NumberSeqApplicationModule numberSeqApplicationModule;
container numberSequenceModules;
numberSequenceModules = [NumberSeqModule::Asset];
numberSeqApplicationModule = new NumberSeqModuleAsset_XXX();
scope = NumberSeqScopeFactory::createDataAreaScope();
NumberSeqApplicationModule::createReferencesMulti(numberSequenceModules, scope);
tmpIdRef.setTmpData(NumberSequenceReference::configurationKeyTableMulti(numberSequenceModules));
args.setArg('tmpIdRef',tmpIdRef);
}
