How to Filter an Array of Objects in Kendo Grid (AngularJS)

Handling data efficiently is crucial for web application development, especially when dealing with frameworks like AngularJS and libraries like Kendo UI. In this guide, we'll explore how to filter an array of objects effectively in a Kendo Grid.

The Problem

Imagine you have a Document object representing a collection of signers, and you want to filter this data displayed in a Kendo Grid. Below is a sample representation of this object:

One column of the Kendo Grid contains the names of these signers, and you may want to filter them, say, by their names, such as "Bob" or even by their country. The challenge comes in when you want to apply this filtering on the client side.

The Solution

To filter the signers in your Kendo Grid, you can utilize the JavaScript filter() method along with Set for efficient checking of names. Below, we’ll walk through the process of implementing this solution.

Step-by-Step Instructions

Create a Set of Names: First, prepare a set containing the names you want to filter.

Additional Considerations

Filtering by Country: If you also want to filter by the country, you can expand your Set to include country values and adjust the filtering logic accordingly.

Client-Side vs Server-Side Filtering: While client-side filtering offers immediate results, consider using server-side filtering for larger datasets to improve performance.

Conclusion

Filtering an array of objects within a Kendo Grid using AngularJS can be straightforward if you leverage JavaScript’s array methods effectively. By making use of the filter() method and Set, you can easily manage how your data is presented based on user input.

This approach not only enhances user experience but also promotes efficient data management within your application. Now you’re equipped to filter signers and make your Kendo Grid even more dynamic!
