[yolo]

Hi, 

i have a drop down tree created, as shown in the attachment below

i need to checked all the checkboxes by default. How to do this?

[yolo]

or how can i let the filter reflects on what are the type of events(holidays, interview,etc) that are present in the view?

for instance, in that week view, i only have events and holidays, and i wan the dropdowntree to automatically checked the events and holidays checkboxes.

Hi Yolo,

You can pre-select the items in the DropDownTree by setting the "expanded" property in the datasource of the component. Here is a Dojo example demonstrating the targeted functionality. The datasource of the DropDownTree in the example is defined as follows. The configuration in yellow will initially check the items that have the "checked" property in their datasource. 

dataSource: [
    {
        text: "Furniture", checked: true, expanded: true, items: [
            { text: "Tables & Chairs", checked: true },
            { text: "Sofas", checked: true },
            { text: "Occasional Furniture", checked: true }
        ]
    },
    {
        text: "Decor", checked: true, items: [
            { text: "Bed Linen", checked: true },
            { text: "Curtains & Blinds", checked: true },
            { text: "Carpets"}
        ]
    }
]

Let me know if the suggested solution works in your scenario.

Hi Petar, thanks for the reply. 

However, im implementing this dropdowntree for the types of event in my scheduler.

 

When i navigate to the next week, the scheduler will show all the events, but the dropdown tree doesn't adapt to the type of event that are being rendered in the scheduler. For instance, i only have checkbox "holidays" checked and all other type of events unchecked for the current week, when i navigate to the next week, the scheduler will show all the events but still remains the same whereby "holidays" are being checked.

also, how the checked the "check all" checkbox by default and have the value for each checkbox to be save in the 

$('dropdowntree').data("kendoDropDownTree").values()

Hi Yolo,

I am afraid that based only on the provided information I can't say what is happening in your application. The way you use the DropDownTree seems to be a complex scenario and to be able to help you, I will need a runnable example in which the reported behavior can be replicated. When I test your scenario locally, I can provide more relevant feedback. 

Can you edit this Dojo example in a way the reported behavior can be replicated and send me the edited project back?
