Tooltip In Kendo Autocomplete

Introduction

Kendo autocomplete is the control that provides a suggestion based on the input given in a text box. In this blog, I’m going to explain how to implement a Kendo tooltip in the autocomplete control to show some additional information about a list item.

Here is a simple demo to implement the Kendo autocomplete with static data source.

  47.   
  48.                     
  49.                     $("#countries").kendoAutoComplete({  
  50.                         dataSource: data,  
  51.                         dataTextField:"code",  
  52.                         dataValueField:"value",  
  53.                         filter: "startswith",  
  54.                         placeholder: "Select country...",  
  55.                         separator: ", "  
  56.                     });  
  57.                 });  
  58.             </script>  
  59.         </div>

Kendo Autocomplete provides a country code suggestion based on the user entry in the text box. Now, let us make it more informative using tooltip.

Using a tooltip, now we are going to display the complete country name to the user, which makes it more informative.

  31.                     var item = autoComplete.dataItem($(e.target));  
  32.   
  33.                     var result = '<h3>' + item.Desc + '</h3>' ;  
  34.                       
  35.                     return result;

  55.         "Desc""United Kingdom"  
  56.     }  
  57.       
  58.                       ]  
  59.   
  60.                     //create AutoComplete UI component  
  61.                     $("#countries").kendoAutoComplete({  
  62.                         dataSource: data,  
  63.                         dataTextField:"code",  
  64.                         dataValueField:"value",  
  65.                         filter: "startswith",  
  66.                         placeholder: "Select country...",  
  67.                         separator: ", "  
  68.                     });  
  69.                 });  
  70.             </script>  
  71.         </div>  
  72.   
  73.   
  74. </body>  
  75. </html>  

From the above code, you can notice that the content of the tooltip will be the description of the country code from the data source with respect to the list item which the user selected.
