Dynamics 365 FO extension

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 Mode
OpenMode 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;
#isoCountryRegionCodes

if (ve.parmFieldName() == fieldStr(LedgerParameters, ChineseVoucher_CN)
&& SysCountryRegionCode::isLegalEntityInCountryRegion([#isoCN]))
{
if ((select firstonly RecId from LedgerJournalTrans
where 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); } }
