Overview

The ASP.NET MVC ComboBox component is a drop-down list with editable textbox that also allows users to choose an option from a predefined pop-up list. It can be used as an alternative to the HTML select tag and has several out-of-the-box features such as data binding, filtering, grouping, cascading, templates, UI customization, pop-up list customization, and more.


ASP.NET MVC ComboBox data binding from different data sources

Data binding

Bind data from different data sources in an array or list of primitive data, JSON data collections, or remote data sources using adapters such as OData, OData V4, URL, JSON, and Web API.

The control uses the Essential JS 2 data manager to manage data, and also has customization options for data requests and processing.


Custom value

The editable combo box allows the entry of a custom value when the option the user searched for is not available in the pop-up list. Also, you can set a value for the combo box or get the selected value from the combo box at any time through the interactive APIs.

Filtering

The combo box provides a built-in filtering support with a rich set of filtering configurations to meet all the application needs.

Custom filtering

Filter queries are customizable, and users can use their own filter libraries to filter data.

The filter search can be customized to be case sensitive, and can be performed with the minimum query string characters.


ASP.NET MVC ComboBox Grouping of pop-up list items based on category

Grouping with category

Group the pop-up list items with a corresponding category that makes it easy for users to pick an item quickly from the drop-down, and also improves the visual experience for users.


Autofill

The autofill option allows users to easily search through the options in the combo box. When a user types a query string to search, the available matching options will be filled automatically.

Cascading combo boxes

The ASP.NET MVC ComboBox control provides an option to create multiple cascading combo boxes. Users can populate the data source of the second ComboBox based on the value selected from the first ComboBox.


Another important combo box feature is templates, which allow you to make custom changes to the header, footer, and list items in the pop-up list to make them look unique.

You can find our ASP.NET MVC ComboBox demo here.

No, our 75+ ASP.NET MVC components, including ComboBox, are not sold individually, only as a single package. However, we have competitively priced the product so it only costs a little bit more than what some other vendors charge for their ComboBox alone. We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all 75+ ASP.NET MVC components for a flat fee of $995/developer. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.

No, this is a commercial product and requires a paid license. However, a free community license is also available for companies and individuals whose organizations have less than $1 million USD in annual gross revenue and five or fewer developers.

A good place to start would be our comprehensive getting started documentation.
