Not within the base VENUS dialog editor, as far as I know. From looking at both the XAML definitions and the HSL being used when the dialog is generated in-run, it appears to pull static parameters/variables prior to opening the dialog window. I’d love to be wrong, but without delving further into XAML capabilities I don’t believe it’s an option. If you’re keeping the dialog open while the method is running, perhaps something like the status dialog window would work for your purposes? I have a method that updates the status dialog as it loads carriers (e.g. “Loading carrier 1 of 3”/“2 of 3” etc), maybe you could finagle that in some way?
If you mean to have a dialog that updates during runtime…not in the sense that you can change the look and view instantly. If you want to update your user, use the statusdialog or ASW.Dialogs (Vector Custom too) and then Status Window. This is built to showcase a user what is happening, line by line.
