Examples Of Formevent Handlers in AX 7

  Here Im using CustGroup Form To Perform Some Operations By using FormEventHandlers.

1.Using On Intilizing EventHandler To disable a Control In CustGroup form.

     Here the Code snippet....

2.Using On clicked EventHandler For a Button 

   [FormControlEventHandler(formControlStr(CustGroup, Clicked), FormControlEventType::Clicked)]

public static void Clicked_OnClicked(FormControl sender, FormControlEventArgs e)

{

// FormRun formRun = sender.formRun() as FormRun;

CustGroup custGroup;

custGroup = sender.formRun().dataSource().cursor(); // to get current activated Record

info(strFmt('%1 - %2 ',custGroup.CustGroup,custGroup.Name));

}

3. Using onInitilized event handler to disable a button 

[formeventhandler(formstr(custgroup), formeventtype::initialized)]

public static void custgroup_oninitialized(xformrun sender, formeventargs e)

{

custgroup custgroup;

formdatasource ds = sender.datasource(formdatasourcestr(custgroup, custgroup)); //current datasource

sender.design().controlname(formcontrolstr(custgroup,clicked)).enabled(false);

custgroup = ds.cursor(); 

info(custgroup.custgroup);

}

3.   Using onActivated event handler 

[formdatasourceeventhandler(formdatasourcestr(Custgroup, Custgroup), formdatasourceeventtype::activated)]

public static void custgroup_onactivated(formdatasource sender, formdatasourceeventargs e)

{

Custgroup custgroup;

// formdatasource ds = sender.datasource(formdatasourcestr(custgroup, custgroup));

FormRun formRun = sender.formRun() as FormRun;

custgroup = sender.cursor();

formRun.design().controlName(formControlStr(Custgroup,Clicked)).enabled(custgroup.CustGroup <='30');

//if(custgroup.CustGroup <='30')

//{

// formRun.design().controlName(formControlStr(Custgroup,Clicked)).enabled(false);

//}

//else

//{

// formRun.design().controlName(formControlStr(Custgroup,Clicked)).enabled(true);

//}

// info(strfmt('%1 - %2 ',custgroup.custgroup,custgroup.name));

}
