How to show lookup on a form's field in D365. #Dynamics #x++ #D365

Here is an example that shows how you can add look up on a field. I wrote my code in OnLookup event. 



public static void LedgerParameters_FinDimName_OnLookup(FormControl sender, FormControlEventArgs e)
    {
        SysTableLookup sysTableLookup = SysTableLookup::newParameters(tableNum(DimensionAttribute), sender);
        sysTableLookup.addLookupfield(fieldNum(DimensionAttribute, Name));        
        Query query = new Query();
        query.addDataSource(tableNum(DimensionAttribute)).addRange(fieldNum(DimensionAttribute, BackingEntityType)).value(queryValue(tableNum(DimensionFinancialTag)));
        sysTableLookup.parmQuery(query);


        //perform lookup
        sysTableLookup.performFormLookup();
        FormControlCancelableSuperEventArgs ce = e as FormControlCancelableSuperEventArgs;
        ce.CancelSuperCall();
    }
