JSON Viewer

The JSON viewer control allows you to visualize JSON text or files sourced from a specified location.

The JSON viewer is particularly valuable when you need to inspect JSON data from files, such as in applications designed for online courses. It enables users to examine predefined sample code or code they are experimenting with independently.

Binding Data Options

JSON Viewer control accepts JSON data to display in a structured format. There are different ways in which you can bind data to the JSON Viewer control.

Static Data Option

To display static JSON data in the JSON Viewer control, you can use the Bind Data option. The Bind Data option must be specified as valid JSON data.

"name": "John Doe",
"age": 30,
"email": ""
"name": "Jane Smith",
"age": 25,
"email": ""
"name": "Michael Johnson",
"age": 40,
"email": ""

Dynamic Data Option

In this example, we have a JSON Viewer Control that displays information about different products in an online store. The data is fetched from a database in JSON format and includes details such as product name, category, price, and availability.

  1. Set up a Data Query: First, make sure you have a data query configured to fetch the product information from your database. The query might look like this:
SELECT product_name, category, price, availability FROM products
  1. Configure the JSON Viewer Control: In the JSON Viewer control, navigate to the Bind Data Options section and select Quick Select -> Data Queries -> yourDataQueryName.

By selecting the data query you've set up (e.g., yourDataQueryName), the JSON Viewer control will automatically fetch the product information from your database and display it in a structured format. Users can view the product names, categories, prices, and availability in an organized manner.

With this JSON Viewer Control, online store administrators and customers can easily view and analyze real-time product information, making informed decisions about purchases and product management.
