Hi 

i have two different controllers, one of them with gantt chart control, and the second one as toolbar with ie. DataPicker and Button which primary function is a commiting new parameters and refresh gantt view. I achieved flow between both controlers  

<div ng-app="KendoDemo" ng-controller="MyCtrl">
<div style="posotion: absolute; top:100px; bottom:0px;text-align:left;display:inline-block;"  ng-controller="Header">              
                <p>
                    <label for="start">Data od:</label><input id="start" style="width: 200px" value="10/10/2011" ng-model="From"/>               
                    <label for="end">Data do:</label><input id="end" style="width: 200px" value="10/10/2012"/ ng-model="To">
   <!--<kendo-button class="k-primary" title="Run snippet (Ctrl + Enter)"
                    data-role="button" ng-click="onClick1()">Szukaj</kendo-button>-->
<button class="k-primary" ng-click="handleClick();">Szukaj</button>
   &nbsp;<b>Styl:</b>
                </p>
            </div>
<input type="hidden" ng-model="From"/>   
<input type="hidden" ng-model="To"/>   
<div kendo-gantt  k-options="ganttOptions" ng-mouseover="enter($event)"></div>
<div kendo-tooltip="tooltip" k-content="'{{tooltipContent}}'"></div>
  </div>    
  </div>

 <script>

                  this.style.backgroundColor = "#9f9";
                }
              });
}
      };

  }

MyCtrl.$inject = ['$scope'];
Header.$inject = ['$scope'];
</script>

and that's ok. I checked new parameters using ordinary alert() function inside of $scope.enter. But i have no idea how to rebind a view. i MVVM it shall looks like:

var viewModel = kendo.observable({
productsSource: new kendo.data.DataSource({
transport: {
read: {
url: crudServiceBaseUrl + "/Products",
dataType: "jsonp"
},‏ and bind

                  kendo.bind($("#form-container"), viewModel);

But in AnguleJS framework IMHO control is binding in background after its embedded in DOM model. I've been trying $apply and this.refresh() but with no success.


Any idea?

Hello,

As you pointed out, you can use the k-rebind attribute to specify a property, and when this property changes the widget is dropped and recreated again. This is explained in detail in our online documentation, under the Updating Widgets when options change section:
http://docs.telerik.com/kendo-ui/AngularJS/introduction

I'm affraid I couldn't quite understand the following line however: "but when i used to it i obtain a reccurency and loader persistent work on."
Could you elaborate on the exact issue in more detail.

Regards,

Hi

An effect  rather than only details, You may see out here: http://dojo.telerik.com/EMIMi

When You change a From value (datepicker upon a gantt chart) and click search button then some kind of recurrent loop appear.

And as curiosity it's not depend of From value, cause the same effect i may achieve using for instance ganttOptions property:

<div kendo-gantt  k-options="ganttOptions" k-rebind="gattOptions"></div>

Hi,

Thank you for getting back to us.

I was able to investigate the issue further and found out that it was caused by a bug in the Gantt widget, involving improper disposing of events. We will fix the issue in our next internal build.

Is this issue has been fixed yet?  I have an angular issue where when I edit a task on the first click, my edit form template is not bind. The Delete, Save or Cancel button aren't working. When I close the form using the X and then open it again, it works the second time.

I'm using angular and used a k-rebing.

<div kendo-gantt k-options="ganttOptions" k-ng-delay="ganttOptions" k-rebind="ganttOptions"></div>

 

For some reason, there is an issue with my template not binding at all.

For some reason, removing the k-rebind property fixed it.

<div kendo-gantt k-options="ganttOptions"></div>

Hello,

We don't recommend using k-rebind to bind to the whole set of widget options, as some unexpected issues arise. If you want to rebind to the whole configuration, we recommend using k-ng-rebind:
