Hi,

Using 2023 R2 SDK.

Using ServerSideCarrosal, we get exceptions when SQL is down and we drag/drop the server side carrosal plugin in SC view.

ServerSideCarrosal is a sample. In general the samples are kept simple and might not include error handling. For production code you might want to develop a better error handling.

We have put a try/catch block in serversidecarrosal. But still not able to catch exceptions. Is there any better way?

public Guid SelectedCarrouselId
{
 
	get { return _selectedCarrouselId; }
	set
	{
		try
		{
			if (_selectedCarrouselId != value)
			{
				_selectedCarrouselId = value;
				SetProperty("SelectedGUID", _selectedCarrouselId.ToString());
 
				Item item = Configuration.Instance.GetItemConfiguration(ServerSideCarrouselDefinition.CarrouselPluginId, ServerSideCarrouselDefinition.CarrouselKind, _selectedCarrouselId);
				CarrouselConfigUtil.BuildCarrouselList(item, CarrouselItems);
 
				SaveProperties();       // Moved down to after the re-build of camera list
			}
		}
		catch (Exception ex)
		{
			MessageBox.Show("Error");
		}
    }
}
 
private void OnLoad(object sender, EventArgs e)
{
	try
	{
		List<Item> items = Configuration.Instance.GetItemConfigurations(ServerSideCarrouselDefinition.CarrouselPluginId, null, ServerSideCarrouselDefinition.CarrouselKind);
		FillContent(items, _carrouselViewItemManager.SelectedCarrouselId);
	}
	catch (Exception ex)
	{
		MessageBox.Show("Error OnLoad");
	}
}

When I first answered I assumed you would be able to catch the exception and avoid the end-user seeing it. With your observation we found that the end-user dialog cannot be avoided, however you should be able to control what happens after the end-user has acknowledge the dialog by catching the exception then. I hope this will better fit your observations.
