Hi
I have extended a form and added an unbound combo box which has a new base enum as its enum type. How do I get the value of the combo box in the OnModified event handler? The sender variable which is of type FormControl doesn't seem to have a selection() method. Do I need to cast this to another type?
Thanks,
Joe

You must realize that the event handler has the same signature for all types of controls, therefore sender is declared as something compatible with all controls (= their common parent class). But the value of you get has a concrete type, such as FormComboBoxControl, and you can cast sender to it to be able to access its methods.

Hi
Here is the code I am using - the event handler has been copied from the combo box object on the form.
[FormControlEventHandler(formControlStr(TransportationDocument, MyComboBox), FormControlEventType::Modified)]
public void MyComboBox_OnModified(FormControl sender, FormControlEventArgs e) { }
I just need to know what value has been selected when a user changes the value.
Thanks,
Joe
Hi,
Could you please elaborate your requirement(or if I am missing something), as I don't think we cannot add eventhandler to the form control modified method.
Thanks,
