Hi Mieke,

I have something similar in which I grey out all the UI Fields and push updates about the progress to a TextBox.

To do this I used the "RequestManualMode" method on the InteractiveController object.
This is a small example of the code:

private readonly InteractiveController controller;
private void Confirm_Pressed(object sender, EventArgs e)
{

controller.RequestManualMode(
() =>
{
StatusTextBox.IsVisible = true;
DisableAllUiFields();
ProgressUpdate($"Prepping action …");
// Do something
});
}

private void ProgressUpdate(string progressString)
{
StatusTextBox.Text += $"\n[{DateTime.Now.ToLocalTime()}] {progressString}";
Show(false);

Engine.GenerateInformation(progressString);
}

I think with this you should be able to create and show a proper loading screen.

Hi Mieke,

We also encountered this use case.

Using the IASToolkit, you can implement it by using the following logic:

• ProgressDialog.Title = "Some Title"; // Set up title for your ProgressDialog
• ProgressDialog.Show(false); // Display ProgressDialog without user interaction
• ProgressDialog.AddProgressLine(string); // Show progress
• ProgressDialog.Finish(); // Finish showing progress
• InterActiveController.ShowDialog(ProgressDialog); // Show ProgressDialog through controller to allow user interaction.

Quick update, while testing this on DM 10.3.4, I noticed that the title was only updating after the progress was finished and I was getting a "Error trapped: Sequence contains no elements" message when running from Dashboards. As a workaround, I created a new simple Dialog that contains a single label with some text. I'm defining my custom title on this dialog and display it just before showing the initial progress.

public class Script
{
private InteractiveController app;

/// <summary>
/// The Script entry point.
/// Engine.ShowUI();
/// </summary>
/// <param name="engine">Link with SLScripting process.</param>
public void Run(Engine engine)
{
try
{
engine.SetFlag(RunTimeFlags.NoKeyCaching);
engine.Timeout = TimeSpan.FromHours(10);
RunSafe(engine);
}
catch (ScriptAbortException)
{
throw;
}
catch (Exception e)
{
engine.Log("Run|Something went wrong: " + e);
ShowExceptionDialog(engine, e);
}
}

private void RunSafe(Engine engine)
{
app = new InteractiveController(engine);

// Define dialogs here
var emptyDialog = new EmptyDialog(engine) { Title = "My Custom Title" };
emptyDialog.Show(false);

ProgressDialog progressDialog = new ProgressDialog(engine) { Title = "My custom title" };
progressDialog.OkButton.Pressed += (s, e) => engine.ExitSuccess("Done");
progressDialog.Show(false);

foreach (var message in new string[] { "Doing something", "Let's wait some more", "Almost there", "Just a little push" })
{
progressDialog.AddProgressLine(message);
engine.Sleep(500);
}

progressDialog.Finish();
app.Run(progressDialog);
}

private void ShowExceptionDialog(Engine engine, Exception exception)
{
ExceptionDialog dialog = new ExceptionDialog(engine, exception);
dialog.OkButton.Pressed += (sender, args) => engine.ExitFail("Something went wrong during the creation of the new event.");
if (app.IsRunning) app.ShowDialog(dialog); else app.Run(dialog);
}

private class EmptyDialog : Dialog
{
public EmptyDialog(IEngine engine) : base(engine)
{
AddWidget(new Label("This is a text"), 0, 0);
}
}
}
