Get formRun, Form control, datasource and selected record from form datasource :

[FormDataSourceEventHandler(formDataSourceStr(MyForm, MyRandomTableDS), FormDataSourceEventType::Written)] public static void MyRandomTableDS_OnWritten(FormDataSource sender, FormDataSourceEventArgs e)
{

FormRun formRun = sender.formRun() as FormRun;

// you can even call custom methods
formRun.myCustomMethod();

// Get the selected datasource record
TableName tableBuffer = sender.cursor();

// Get datasource variable
FormDataSource DSVariable = sender.formRun().dataSource(“TableName”);
}

Get form datasource from xFormRun
[FormEventHandler(formStr(SomeForm), FormEventType::Initialized)] 

public static void SomeForm_OnInitialized(xFormRun sender, FormEventArgs e)
{
FormDataSource MyRandomTable_ds = sender.dataSource(formDataSourceStr(SomeForm, MyRandomTableDS));
…
}

Access form control from xFormRun
[FormEventHandler(formStr(SomeForm), FormEventType::Initialized)] 

public static void SomeForm_OnInitialized(xFormRun sender, FormEventArgs e)
{
// set the control to invisible as an example
sender.design().controlName(formControlStr(SomeForm, MyControl)).visible(false);
}

Get FormRun from form control
[FormControlEventHandler(formControlStr(MyForm, MyButton), FormControlEventType::Clicked)] public static void MyButton_OnClicked(FormControl sender, FormControlEventArgs e)
{
FormRun formRun = sender.formRun() as FormRun;
formRun.myCustomMethod();
}

Get current record in form control event
[FormControlEventHandler(formControlStr(SomeForm, SomeButton), FormControlEventType::Clicked)] public static void SomeButton_OnClicked(FormControl sender, FormControlEventArgs e)
{
// as an example the datasource number is used for access; I perceive the formDataSourceStr as more robust
SomeTable callerRec = sender.formRun().dataSource(1).cursor();
}
