Reload after DismissDialog

Question

Hello,

Is there a way to InvalidateViewState() of a Dialog after Dismissing a dialog presented ontop of the original one?

I was thinking about overriding the method Done() in the dialog i dissmissed  including Owner.InvalidateViewState() in it, so the underlaing dialog gets updated?

Thanks.

Hello Riccardo,

the Done() method is not allowed to access foreign objects. Therefore this approach will not work.

Anyway, whether a component actually acts as dialog or not, is reflected in the Dialog state of this component (See also Handle the view state of the Dialog). This state changes when the component is presented and it changes again when the component is dismissed. You could thus implement in the corresponding component the method UpdateViewState() and react there on the alternation of the Dialog state. This could include the invocation of Owner.InvalidateViewState().

Please note, Owner may become null. Therefore add if-condition to test whether Owner is valid before invoking InvalidateViewState().

I hope it helps you further.

Best regards
