Purpose:
The purpose of this document is to show how to override form control methods without overlaying in Dynamics 365 for Operations
Development:
To demonstrate
we are using the HRMCompFixedEmplActionDialog form and going to override the planId_Control lookup method.
First of all, create new event
handler class HRMCompFixedEmplActionDialogEventHandler and subscribe
to post-event handler of form init.
/// <summary>
/// The
<c>HRMCompFixedEmplActionDialogEventHandler</c> class is the event
handler class
/// for managing
HRMCompFixedEmplActionDialog form events
/// </summary>
class
HRMCompFixedEmplActionDialogEventHandler
{
///
<summary>
/// Post event handler for
HRMCompFixedEmplActionDialog
///
</summary>
///
<param name="_args">Event args</param>
[PostHandlerFor(formStr(HRMCompFixedEmplActionDialog), formMethodStr(HRMCompFixedEmplActionDialog, init))]
public static void
HRMCompFixedEmplActionDialog_Post_init(XppPrePostArgs _args)
{
FormRun formRun =
_args.getThis();
var methodOverrides =
HRMCompFixedEmplActionDialogEventHandler::construct();
FormStringControl PlanIdctrl =
formRun.design().controlName(formControlStr(HRMCompFixedEmplActionDialog, planId_Control));
PlanIdctrl.registerOverrideMethod(methodStr(FormStringControl, lookup), methodStr(HRMCompFixedEmplActionDialogEventHandler,
LookupPlanId ), methodOverrides );
}
///
<summary>
///
Constructs a new instance of
<c>HRMCompFixedEmplActionDialogEventHandler</c> class.
///
</summary>
///
<returns>
///
A <c>HRMCompFixedEmplActionDialogEventHandler</c> class.
///
</returns>
public static HRMCompFixedEmplActionDialogEventHandler
construct()
{
return new
HRMCompFixedEmplActionDialogEventHandler();
}
///
<summary>
/// Overrided method for Plan id lookup
///
</summary>
///
<param name="_ctrl">
///
FormStringControl buffer
///
</param>
public void LookupPlanId(FormStringControl _ctrl)
{
SysTableLookup sysTableLookup = SysTableLookup::newParameters(tableNum(HRMCompFixedPlanTable), _ctrl);
Query query;
QueryBuildDataSource qbds =
query.addDataSource(tablenum(HRMCompFixedPlanTable));
sysTableLookup.addLookupfield(fieldNum(HRMCompFixedPlanTable, PlanId));
sysTableLookup.addLookupfield(fieldNum(HRMCompFixedPlanTable, Description));
sysTableLookup.addLookupfield(fieldNum(HRMCompFixedPlanTable, Type));
sysTableLookup.addLookupfield(fieldNum(HRMCompFixedPlanTable, CurrencyCode));
sysTableLookup.addLookupfield(fieldNum(HRMCompFixedPlanTable, PayFrequencyId));
sysTableLookup.parmQuery(query);
sysTableLookup.performFormLookup();
}
}
Using this the approach we can override any form of control methods
