set check all to all drop downs

[Manolo]

Hi,

I need set check all in a lot of drop down list. So I try simplify this code

https://help.syncfusion.com/aspnetmvc/dropdownlist/howto?cs-save-lang=1&cs-lang=js#add-check-all-option-in-popup-list

In the attach example, I remove teh check id, and all drop downs have teh same create event. In my code, I can check/uncheck Groups drop down, but only check all countries ddl, not uncheck all.

What happened?

Other better solution will be accepted ;)

Thanks

Hi Manolo, 

Thank you for contacting Syncfusion forums. 

We have checked your sample code. To make uncheckAll method to work properly, we suggest you to use string values in the value fields. Kindly refer to the following code  

[controller] 

    public class Countries 

    { 

        public string text { get; set; } 

        public string category { get; set; } 

        public string value { get; set; } 

        public string parentId { get; set; } 

        public string sprite { get; set; } 

        public string country { get; set; } 

        public int id { get; set; } 

        public int parent { get; set; } 

    } 

We have modified the sample, please find the sample from the following link: http://www.syncfusion.com/downloads/support/forum/134585/ze/DropDownProblem-802386460

Is there another way that the data type is not changed?

Why checkAll works and uncheckAll not?
