Lookup on form datasource field

Posted on by Krushna

Lookup does not work on form data source field via chain of command. Though lookup works via event handler, I seek your input on achieving this by chain of command.

VERSION INFORMATION
Installed product version : Microsoft Dynamics 365 for Finance and Operations (10)
Installed platform version : Update26

[ExtensionOf(formDataFieldStr(InventNonConformanceTableCreate,InventNonConformanceTable,MyStingControl))]
final class FARInventNonConfTableCreateFrmCtrl_Extension
{
public void lookup(FormControl _control,str _filter)
{
next lookup(_control,_filter);

Query query = new Query();
query.addDataSource(tableNum(DirOrganization));

SysTableLookup sysTableLookup = SysTableLookup::newParameters(tableNum(DirOrganization),_control);

sysTableLookup.addLookupfield(fieldNum(DirOrganization,PartyNumber));
sysTableLookup.addLookupfield(fieldNum(DirOrganization,Name));

sysTableLookup.parmQuery(query);
sysTableLookup.performFormLookup();
}

}

Hi,

You are using the form control's event handler. Try this code: msdynamics.nevoitech.com/.../how-to-create-lookup-in-form-data-source-field-in-d365fo

I know this is an old post, however, I came across the need to override the lookup on a form datasource field. I used the link shared on how to do via event handler which works good.

As far as chain of command, I don't see how that would work. You have to call the 'next lookup', but that would then cause the original lookup to occur which is not what we want. I don't think chain of command is something that can be used in this situation.

You missed calling registeroverride method which can override the existing lookup from standard.
