Repository Description: A Blazor Server application demonstrating how to implement cascading ComboBox components using Syncfusion, where dependent ComboBoxes automatically populate based on parent selection values.
This project explains how to create a cascading Blazor ComboBox in a Blazor Server Application. Cascading ComboBoxes allow you to build dependent dropdown lists where the options in one ComboBox depend on the selection made in another ComboBox. This pattern is commonly used for scenarios like country-state-city selections or category-subcategory filtering.
This sample demonstrates the implementation of cascading ComboBox components using Syncfusion's Blazor ComboBox control, showing best practices for handling data binding and event management in a Blazor Server environment.
- Visual Studio 2022 - Required for development and debugging
- .NET 6.0 or higher - Core framework requirement
- Blazor Server - Web framework for this application
- Basic knowledge of Blazor and C# programming
Follow these steps to set up and run the application:
-
Clone or Download: Checkout this project to a location on your disk.
-
Open in Visual Studio: Open the solution file using Visual Studio 2022.
-
Restore Dependencies: Restore the NuGet packages by rebuilding the solution. This downloads all required Syncfusion libraries and dependencies.
-
Run the Application: Execute the project. The Blazor Server application will start and be accessible in your browser.
In a cascading ComboBox setup:
- The parent ComboBox contains initial options
- When a user selects a value, it triggers a change event
- The change event filters or fetches data for the dependent ComboBox
- The dependent ComboBox dynamically updates with the filtered data
- This pattern can be extended to multiple levels of cascading
