FluentSortableList Not Working In Hybrid App

by ADMIN 45 views

Introduction

FluentUI is a popular UI library for building web applications, and its Blazor components are widely used in the .NET community. However, when it comes to Blazor Hybrid (MAUI) applications, some components may not function as expected. In this article, we will delve into the issue of FluentSortableList not working in a Blazor Hybrid environment and explore possible causes and solutions.

The Problem

When attempting to use the FluentSortableList component in a Blazor Hybrid application, the drag and drop functionality doesn't work, and items remain unmovable. This is a significant issue, as the component is designed to allow users to reorder items by dragging and dropping them.

Repro or Code Sample

To reproduce the issue, you can clone the following GitHub repository:

https://github.com/parko65/MauiApp3.git

This repository contains a basic Blazor Hybrid application that demonstrates the issue with FluentSortableList.

Expected Behavior

In a regular Blazor Server/WebAssembly application, the FluentSortableList component functions correctly, allowing users to drag and drop items to reorder them. We expect the same behavior in a Blazor Hybrid application.

Current Behavior

The FluentSortableList component renders visually in the Blazor Hybrid application, but it doesn't respond to drag interactions. Items cannot be sorted or moved, making the component unusable.

Possible Causes

Based on our investigation, the issue might be related to two possible causes:

1. Web-Components Script Not Being Properly Loaded

There is a known issue with Blazor Hybrid where the web-components script is not imported automatically. This script is necessary for the web-components to function correctly. Additionally, the custom event handlers that are being configured by the web-components script may not be properly initialized in the WebView environment.

2. JS Interop Events Not Being Properly Initialized

The JS interop events that enable drag-and-drop functionality may not be properly initialized in the WebView environment. This could be due to the way the events are being configured or the fact that the WebView environment is not properly set up to handle these events.

Possible Solution

Unfortunately, we have not found a solution to this issue yet. However, we are actively working on resolving the problem and will provide an update as soon as a solution is available.

Context

The FluentSortableList component is based on SortableJS, which requires proper JavaScript initialization. Other FluentUI components work correctly in the same application, which suggests that the issue is specific to the Blazor Hybrid context.

Your Environment

To help us better understand the issue, please provide the following information about your environment:

  • OS: Windows 11 (or your OS)
  • .NET Version: 9.0 (or your version)
  • FluentUI.AspNetCore.Components Version: 4.11.8
  • Project Type: Blazor Hybrid (MAUI)

By providing this information, you will help us narrow down the possible causes and find a solution to this issue.

Conclusion

In conclusion, the FluentSortableList component is not functioning correctly in a Blazor Hybrid environment. have identified two possible causes for this issue and are actively working on resolving the problem. In the meantime, we recommend using the component in a regular Blazor Server/WebAssembly application or exploring alternative solutions for your Blazor Hybrid application. We will provide an update as soon as a solution is available.
