FormControl LookUp:

[FormControlEventHandler(formControlStr(SalesTable, DiplItemProductType), FormControlEventType::Lookup)]

public static void DiplItemProductType_OnLookup(FormControl sender, FormControlEventArgs e)
{

SysTableLookup sysTableLookup = SysTableLookup::newParameters(tableNum(InventTable), sender);

QueryBuildDataSource            qbdsProduct,qbdsInvent;
Query                                        query;
FormRun                                   formRun;
FormControl                              formCtrl;

           formRun = sender.formRun();
           formCtrl = formRun.design().controlName(formControlStr(SalesTable, DiplItemProductType));

           query           = new Query();qbdsInvent = query.addDataSource(tableNum(InventTable));
           qbdsProduct = qbdsInvent.addDataSource(tableNum(EcoResProduct));
           qbdsProduct.addLink( fieldNum(InventTable, Product), fieldNum(EcoResProduct, RecId));
          qbdsProduct.addRange(fieldNum(EcoResProduct, ProductType)).value(SysQuery::value  (EcoResProductType::Service));

          sysTableLookup.addLookupfield(fieldNum(InventTable, ItemId), true);
          sysTableLookup.addLookupfield(fieldNum(InventTable, ItemType), true);
          sysTableLookup.parmQuery(query);
          sysTableLookup.performFormLookup();

 }  

FormControl Modified:

[FormControlEventHandler(formControlStr(SalesTable, SalesLine_ItemId), FormControlEventType::Modified)]
public static void SalesLine_ItemId_OnModified(FormControl sender, FormControlEventArgs e)

{

FormRun              element = sender.formRun();
FormControl        itemidctrl = element.design(0).controlName("SalesLine_ItemId");
FormDataSource SalesLine_ds = element.dataSource(formDataSourceStr(SalesTable, SalesLine)) as FormDataSource;
SalesLine           salesLine = SalesLine_ds.cursor();

salesLine.DiplItemId = itemidctrl.valueStr();

}

Modified method for unbound controls of a form

Grid field appear/disappear based on  field status

My scenario : Based on unbound enum field in form, grid field should be apper/disapper.

Solution: I have copied onmodified event for filed and created and pasted in new class as shown below.

class DIPLCustomerEH
{

 [FormControlEventHandler(formControlStr(DIPLCustomer, DIPLCustomer_AccountType), FormControlEventType::Modified)]

public static void DIPLCustomer_AccountType_OnModified(FormControl sender, FormControlEventArgs e)
{

 

FormRun element = sender.formRun();

FormComboBoxControl schemactrl = element.design(0).controlName("DIPLCustomer_AccountType");

FormDataSource DIPLCustomer_ds = element.datasource(FormDataSourcestr(DIPLCustomer,DIPLCustomer)) as FormDataSource;

 

FormDataObject schema = DIPLCustomer_ds.object(fieldNum(DIPLCustomer, Sechema));

 

if(schemactrl.selection() == DIPLAccountType::Debit)

{

schema.visible(false);

}

else

 

{

schema.visible(true);

}

  }

}
