1. 窗体控件不再支持Active X 控件和ManagedHost控件，取而代之的是一种可扩展的控件架构。

2. 获得窗体的DataSource

[FormEventHandler(formStr(HcmPosition), FormEventType::Initialized)]public static void HcmPosition_OnInitialized(xFormRun sender, FormEventArgs e){FormDataSource hcmosition_ds = sender.dataSource(formDataSourceStr(HcmPosition, HcmPosition));Or 
FormDataSource                              hcmosition_ds = sender.dataSource('HcmPosition');}

 

3. FormDataSource的EventHandler获得FormRun

 

[FormDataSourceEventHandler(formDataSourceStr(HcmPosition, HcmPosition), FormDataSourceEventType::Created)]public static void HcmPosition_OnCreated(FormDataSource sender, FormDataSourceEventArgs e){FormRun formRun = sender.formRun() as FormRun;}

 

4. 通过FormControl的EventHandler获得FormRun

 

[FormControlEventHandler(formControlStr(HcmPosition, HcmPosition_PositionId1), FormControlEventType::Modified)]public static void HcmPosition_PositionId1_OnModified(FormControl sender, FormControlEventArgs e){FormRun formRun = sender.formRun() as FormRun;}

 

5. 获得窗体上的FormControl

[FormEventHandler(formStr(HcmPosition), FormEventType::Initialized)]public static void HcmPosition_OnInitialized(xFormRun sender, FormEventArgs e){sender.design().controlName(formControlStr(HcmPosition, HcmPositionNewPosition)).AllowEdit(false);// to get form open ModeOpenMode                                    openMode = sender.args().openMode();}

 

6. 获得Current Record

 

[FormControlEventHandler(formControlStr(HcmPosition, HcmPositionNewPosition), FormControlEventType::Clicked)] public static void HcmPositionNewPosition_OnClicked(FormControl sender, FormControlEventArgs e) { HcmPosition hcmposition = sender.formRun().dataSource(1).cursor();

            HcmPosition hcmposition = sender.args().record(); }

 

7. 使用DataEventArgs发送验证结果

[DataEventHandler(tableStr(CategoryTable), DataEventType::ValidatingDelete)]public static void CategoryTable_onValidatingDelete(Common _sender, DataEventArgs _e){CategoryTable categoryTable = _sender as CategoryTable;ValidateEventArgs validateEventArgs = _e as ValidateEventArgs;boolean ret = true;if (categoryTable.UseInProject){ProjCategory projCategory = ProjCategory::find(categoryTable.CategoryId);ret = projCategory.validateDelete();}if (ret && categoryTable.UseInExpense){TrvCostType trvCostType = TrvCostType::find(categoryTable.CategoryId);ret = trvCostType.validateDelete();}if (!ret){validateEventArgs.parmValidateResult(false);}}

 

8. 用 ValidateFieldValueEventArgs 发送验证结果给Validate Field method

 

[DataEventHandler(tableStr(LedgerParameters), DataEventType::ValidatingFieldValue)]public static void LedgerParameters_onValidatingFieldValue(Common sender, DataEventArgs e){ValidateFieldValueEventArgs ve = e;boolean isValid = true;LedgerParameters ledgerParameters = sender as LedgerParameters;#isoCountryRegionCodesif (ve.parmFieldName() == fieldStr(LedgerParameters, ChineseVoucher_CN) && SysCountryRegionCode::isLegalEntityInCountryRegion([#isoCN])){if ((select firstonly RecId from LedgerJournalTranswhere LedgerJournalTrans.LedgerVoucherType_CN != 0|| LedgerJournalTrans.Voucher_CN != '').RecId != 0){// The general journal needs to be empty in order to modify the setup for the Chinese voucher system.isValid = checkFailed("@GLS54497");}ve.parmValidateResult(isValid);}}

Form data source event handler

 

 [FormDataSourceEventHandler(formDataSourceStr(EcoResProductDetailsExtended, InventTable), FormDataSourceEventType::Written)]

public static void InventTable_OnWritten(FormDataSource sender, FormDataSourceEventArgs e){

    FormRun                 form           = sender.formRun();

    FormDataSource          InventTable_ds =       form.dataSource(formDataSourceStr(EcoResProductDetailsExtended,InventTable)) as FormDataSource;

   InventTable             inventTable    = InventTable_ds.cursor();

}

 

Form event handler

Table Buffer on form closing event

 

[FormEventHandler(formStr(EcoResAttributeValue), FormEventType::Closing)]

public static void EcoResAttributeValue_OnClosing(xFormRun sender, FormEventArgs e)

{

     FormDataSource ecoResProduct_ds   =          sender.dataSource(formDataSourceStr(EcoResAttributeValue, EcoResProductAttributeValue));

      EcoResProductAttributeValue      ecoResAttributeValue = ecoResProduct_ds.cursor();

}   

 

 

Control value and form event level for which auto declaration must be set true

 

[FormControlEventHandler(formControlStr(EcoResProductCreate, OKButton), FormControlEventType::Clicked)]

public static void OKButton_OnClicked(FormControl sender, FormControlEventArgs e)

{

       FormRun             element       = sender.formRun();

       //form control

       FormControl         modelGroupRef = element.design(0).controlName("ModelGroupId");

        Info(strfmt(“Model Group %1”, modelGroupRef.valueStr()));

       //form parameter

       ItemId              itemId        = element.parmItemId();

}

 

Post handler for class method

 

[PostHandlerFor(classStr(EcoResProductReleaseManager), methodStr(EcoResProductReleaseManager, release))]

public static void EcoResProductReleaseManager_Post_release(XppPrePostArgs args){

     EcoResProductReleaseManager releaseMgr;

    //Getting the class object

    releaseMgr     = args.getThis();

   //Getting the class parameter

   ItemId itemId  = releaseMgr.parmItemId();

   //Getting the method argument

    boolean itemCreation = args.getArg("_isCreation");

}

 

Post handler for overriding table methods modified field and validate Write

 

[PostHandlerFor(tableStr(InventTable), tableMethodStr(InventTable, validateWrite))]

public static void InventTable_Post_validateWrite(XppPrePostArgs args)

{

      InventTable inventTable = args.getThis() as InventTable

      boolean ret = true;

      // Override the validations here and set the return value accordingly.

       Args.setReturnValue(ret);

}

 

[PostHandlerFor(tableStr(InventTable), tableMethodStr(InventTable, modifiedField))]

public static void InventTable_Post_modifiedField(XppPrePostArgs args)

{

        //Getting the table buffer

        InventTable inventTable = args.getThis() as InventTable

       //Getting the field id method argument.

        FieldId fieldModified = args.getArg("_fieldId");

        switch (fieldModified)

        {

            //Here you can write your logic on modified field method

                break;

        }

}

窗体内的方法

[ExtensionOf(formStr(PurchTable))]
final class RIC_PurchTable_Extension
{/// <summary>////// </summary>/// <param name="args"></param>[PostHandlerFor(formStr(PurchTable), formMethodStr(PurchTable, updateControlsForFrenchConfirmedPO))]public static void PurchTable_Post_updateControlsForFrenchConfirmedPO(XppPrePostArgs args){FormRun sender = args.getThis();FormDataSource purchTable_DS;PurchTable purchTable;boolean canEnable;if (PublicSectorUtils::isFrenchRegulatoryEnabled()){purchTable_DS = sender.dataSource(formDataSourceStr(PurchTable, PurchTable));purchTable = purchTable_DS.cursor();canEnable = purchTable.canModifyPurchaseOrder();purchLine_PurchPriceGrid.allowEdit(canEnable);}}}

Override Form DataSource method using Extensions in D3fO

[FormDataSourceEventHandler(formDataSourceStr(SalesTable, SalesLine), FormDataSourceEventType::Activated)] public static void SalesLine_OnActivated(FormDataSource sender, FormDataSourceEventArgs e) {              FormDataSource      fds = sender.formRun().dataSource("SalesLine");         SalesLine           salesline = fds.cursor();         FormRun             fr = sender.formRun();         FormControl         fc = fr.design(0).controlName("CreateServiceOrder");                if(salesLine.ProjID)         {             fc.enabled(true);         }         else         {             fc.enabled(false);         }     }
