How to set default value in Kendo dropdownlist using jQuery?

Kendo dropdownlist is a powerful JavaScript-based UI component that allows users to select from a list of predefined options. It provides a seamless and intuitive user experience. Sometimes, we may want to set a default value for the dropdownlist, so that a specific option is preselected when the page loads. In this article, we will explore how to achieve this using jQuery.

The answer is:

To set a default value in Kendo dropdownlist using jQuery, you can use the value method provided by the Kendo DropDownList widget. This method allows you to programmatically set the value of the dropdownlist. By using jQuery to select the dropdownlist by its ID or class and calling the value method with the desired default value, you can set the default selection. Below is an example:
