Header And No Data Template In Kendo Drop Down List

Introduction

In this blog, I’ll describe how to implement the header and no data template in Kendo DropDownList. To explain the implementation of these templates in Kendo DropDownList, I have used HTML page with the Kendo UI framework

Prerequisites

Basic knowledge in HTML 5, jQuery, and Kendo UI framework.

Create a HTML page

Create a new HTML page in your application. In my case, I named it as Kendo DropDownList.html.

Header Template

Basically, the header template will be rendered as a header of the DropDownList. In Kendo, DropDownList is initialized through the headerTemplate property. 

KendoDropDownList.html
  1.    <!DOCTYPE html>  
  2. <html>  
  3. <head>  
  4.     <meta charset="utf-8"/>  
  5.     <title>Kendo UI Snippet</title>  
  6.   
  7.     <link rel="stylesheet" href="http://kendo.cdn.telerik.com/2016.3.1028/styles/kendo.common.min.css"/>  
  8.     <link rel="stylesheet" href="http://kendo.cdn.telerik.com/2016.3.1028/styles/kendo.rtl.min.css"/>  
  9.     <link rel="stylesheet" href="http://kendo.cdn.telerik.com/2016.3.1028/styles/kendo.silver.min.css"/>  
  10.     <link rel="stylesheet" href="http://kendo.cdn.telerik.com/2016.3.1028/styles/kendo.mobile.all.min.css"/>  
  11.   
  12.     <script src="http://code.jquery.com/jquery-1.12.4.min.js"></script>  
  13.     <script src="http://kendo.cdn.telerik.com/2016.3.1028/js/kendo.all.min.js"></script>  
  14. </head>  
  15. <body>  
  16.   <h2>Header Template</h2>  
  17.   <br>  
  18. <input id="dropdownlist" />  
  19. <script>  
  20. $("#dropdownlist").kendoDropDownList({  
  21.   dataSource: [  
  22.     { id: 1, name: "India" },  
  23.     { id: 2, name: "China" },  
  24.     { id: 3, name:"Australia"}  
  25.   ],  
  26.   dataTextField: "name",  
  27.   dataValueField: "id",  
  28.   headerTemplate: '<div><h2>Countries</h2></div>'  
  29. });  
  30. </script>  
  31. </body>  
  32. </html>  

From the code mentioned above, you can notice the list of countries will be displayed in the DropDownList with the header as “Countries”.

Result
  
No data template

No data template is used to show a message when the DropDownList contains an empty list.

Write the code given below to enable the no data template in DropdDownList.

  1. <input id="dropdownlist1" />  
  2. $("#dropdownlist1").kendoDropDownList({  
  3.   dataSource: [],  
  4.   dataTextField: "name",  
  5.   dataValueField: "id",  
  6.   noDataTemplate: 'No Data To Display'  
  7. });  
Result
 
Complete code is given below in KendoDropDownList.html. 
  1. <!DOCTYPE html>  
  2. <html>  
  3. <head>  
  4.     <meta charset="utf-8"/>  
  5.     <title>Kendo UI Snippet</title>

  32. });  
  33.   
  34. $("#dropdownlist1").kendoDropDownList({  
  35.   dataSource: [],  
  36.   dataTextField: "name",  
  37.   dataValueField: "id",  
  38.   noDataTemplate: 'No Data To Display'  
  39. });  
  40. </script>
