Hi guys,
I am trying to add some logic in some screens of a custom DW10 App.
I am trying to get to something like this:

More specifically, inject an Alert above the first element of the page.
Is this something already wired in the existing logic?

Thank you,
Adrian

Hi Adrian,
if you have some custom implemented list screen inherited from the ListScreenBase<T> class then you can override the GetAlert method to show the alert on your page:
protected override CoreUI.Displays.Information.Alert? GetAlert()
{
    if (_showAlert)
        return new CoreUI.Displays.Information.Alert
        {
            Type = CoreUI.Displays.Information.AlertType.Warning,
            Value = "Alert text"
        };
    return null;
}
BR, Dmitrij
