I have need to create kendo auto completes dynamically, where each one could potentially have thousands of records... Thus, I am wanting to call my controller, get data from a Salesforce database based on the current search, then reset the dataSource of the auto complete with returned data in the filtering event.

 

My code is: 

if(fieldMap[i].fieldType == 'REFERENCE'){
                      extraString = '<div class="k-edit-label"><label for="'+fieldMap[i].fieldName+'Input">'+fieldMap[i].fieldLabel+'</label></div><div data-container-for="'+fieldMap[i].fieldName+'Input" class="k-edit-field" id="'+fieldMap[i].fieldName+'Container">';
                            dynamicComponent = '<select id="'+fieldMap[i].fieldName+'Input" type="text" data-role="dropdownlist" style="width: 150px">';
                            optString = '';
                            for(var k = 0; k < fieldMap[i].referenceList.length; k++){
                                if(k == 0){
                                optString += '<option value="'+fieldMap[i].referenceList[k]+'" selected>'+fieldMap[i].referenceList[k]+'</option>';   
                                } else{
                                optString += '<option value="'+fieldMap[i].referenceList[k]+'">'+fieldMap[i].referenceList[k]+'</option>';   
                            }
                            }
                            optString += '</select>';
                            var inputString = '<input data-role="autocomplete" data-filter="contains" data-source="testData" id="'+fieldMap[i].fieldName+'SearchInput"/></div>';
                            dynamicComponent = dynamicComponent + optString + inputString;
                            
                        }
                    
                    extraString += dynamicComponent;
                        //editorTemplateString += extraString;
                    $('#editor_template').append(extraString);
                        extraString = '';
                        dynamicComponent = '';
                        if(fieldMap[i].fieldType == 'REFERENCE'){
                            kendo.init($('#'+fieldMap[i].fieldName+'SearchInput'));
                            var autoComp = $('#'+fieldMap[i].fieldName+'SearchInput').data('kendoAutoComplete');
                            autoComp.bind('filtering', autoComplete_filter);
                            console.log($('#'+fieldMap[i].fieldName+'SearchInput').data('kendoAutoComplete'));
                            
                        }
                    }

 

which seemingly seems to successfully create kendo auto complete widgets with dummy data in testData right now. However, autoComplete_filter method is never being called when I type in the box. That method is simply:

function autoComplete_filter(e){
                console.log(e);   
                }

right now... but nothing prints out in the console when I type in the auto complete box.

How do I set the filtering event on dynamically created auto completes like this? Also, how can I set the minLength to three? It starts filtering after the first character entered and I only want it to start after 3 or more are entered.

 

Thank you for any help.

Hello,

From the code provided I could not see where you initialize the widget. Here is a sample dojo where similar dummy scenario works correctly. This is the part where the control is actually created :
$("#autocomplete").kendoAutoComplete({
  dataSource: [ "Apples", "Oranges" ]
});

Hope this will help you solve the issue.

Hi,

It is not quite clear what you mean but it is still running correctly at my side even after adding both these properties - just it is starting to fire after the 3rd character - https://dojo.telerik.com/@zdravkov/IjUVAROB.
