ProgressBarViewItem
The ProgressBarViewItem
package integrates a UI progress for long running tasks.
This is a platform agnostic
module that registers a ProgressViewItem
into the ViewItems of your application.
.
This is a ViewItem and is not bound to a property. To add it in a DetailView Layout you have first to add it in the IModelViewItems collection.
Let's assume you have a long running task such as an import which is done in a different thread and an asynchronous sequence emits its progress. To bind the sequence to a DetailView ProgressViewItem we have to:
var progressBarViewItem = View.GetItems<ProgressBarViewItemBase>().First();
progressBarViewItem.Start();
The ProgressViewItem
implements the IObserver<decimal>
so after start the binding becomes as simple as:
await signal.Cast<Decimal>.Do(progressBarViewItem);
The ProgressBarViewItem
features completion notification which can be configured like:
progressBarViewItem.SetFinishOptions(new MessageOptions(){});
Possible future improvements:
Any other need you may have.
Let me know if you want me to implement them for you.
The module is integrated with the ExcelImporter
.
Next we see how it looks on Desktop:
and the same view on the web:
-
First you need the nuget package so issue this command to the
VS Nuget package console
Install-Package Xpand.XAF.Modules.ProgressBarViewItem
.The above only references the dependencies and nexts steps are mandatory.

you need to enable Source Server support
in your Visual Studio/Tools/Options/Debugging/Enable Source Server Support. See also How to boost your DevExpress Debugging Experience.
If the package is installed in a way that you do not have access to uninstall it, then you can unload
it with the next call at the constructor of your module.
Xpand.XAF.Modules.Reactive.ReactiveModuleBase.Unload(typeof(Xpand.XAF.Modules.ProgressBarViewItem.ProgressBarViewItemModule))
The module is tested on Azure for each build with these tests. All Tests run as per our Compatibility Matrix
