How to set default value in Kendo DropDownList

How to set default value in Kendo DropDownList

In Kendo UI, you can set a default value for a DropDownList using the value property or by setting the value attribute in the HTML markup. Here's how you can achieve this:

Method 1: Using the value Property in JavaScript:

<!-- HTML --> <select id="myDropDownList"></select> <!-- JavaScript --> <script> $(document).ready(function () { // Initialize the DropDownList $("#myDropDownList").kendoDropDownList({ dataTextField: "text", dataValueField: "value", dataSource: [ { text: "Option 1", value: "1" }, { text: "Option 2", value: "2" }, { text: "Option 3", value: "3" } ], value: "2" // Set the default value here }); }); </script>

In the above example, the value property is set to "2" to specify the default value. Adjust the value according to the option you want to be selected by default.

Method 2: Using the value Attribute in HTML Markup:

<select id="myDropDownList" data-role="dropdownlist" data-value="2"> <option value="1">Option 1</option> <option value="2">Option 2</option> <option value="3">Option 3</option> </select> <script> // Initialize the DropDownList $(document).ready(function () { $("#myDropDownList").kendoDropDownList(); }); </script>

In this method, the data-value attribute is set in the HTML markup to specify the default value.

Choose the method that suits your requirements and coding style. Both methods allow you to set a default value for a Kendo DropDownList.
