recover DropDownList name or pass additional parameters on clientEvents

[Juan Acosta]

Hi.

I have a dropdownList

@Html.EJ().DropDownList("containersList").Datasource((IEnumerable<DocTracerPortal.Models.Visual.VisualContainer>)ViewBag.containersSource).DropDownListFields(f => f.Value("parentId").Text("text")).CascadeTo("areasList,documentCategoriesList,documentCategoriesList,documentStatusList,documentActionList").EnableRTL(true).ClientSideEvents(e => e.Change("onItemContainerChange"))

I want to recover the dd id on the Event 

function onItemContainerChange(args)

{

 var currentTarget = args.currentElement;

var parentID = $(currentTarget)[0].id;

}

I used that kind of call to get the values from a treeview. I will have that event connected to multiple instances. 

But, I cannot find the way to pass a parameter in the event call, for instance ClientSideEvents(e => e.Change("onItemContainerChange(verify)"))

And if I try to check args, args return the model value of the dropdownlist but it does not contain the object parent reference that triggers the event initially. 

args

Object {

text: "ACT/NSW", selectedText: "ACT/NSW", itemId: 0, selectedValue: 1, value: 1…

}

cancel: falseisChecked: true

isInteraction: true

itemId: 0

model: Object

selectedText: "ACT/NSW"

selectedValue: 1

text: "ACT/NSW"

type: "change"

value: 1__proto__: Object

There is any way to do this.

Hi Juan,   

Thanks for contacting Syncfusion support.   

Query 1: I want to recover the dd id on the Event. I used that kind of call to get the values from a treeview. I will have that event connected to multiple instances.    

 We can get the current control id in the change event by using the “this.element[0].id” as shown below code:   

 

<code> 

 

function onItemContainerChange(args) { 

      var currentTarget = this.element[0].id; 

    } 

</code> 

 

 In this, you can get the current target element id of the desired component. Also, the corresponding component selected value in the args.model. For example, if you need to get the Dropdownlist selected value in change event, then you can get the value by using the args.model.value.   

 

We have prepared the sample based on this and it is available under the following link: 

 

Sample: Sample 

 

Also, we need to clarify that whether the given sample meets your requirement or we misunderstood, if so please provide more details about the requirement and it will be easy for us to provide the exact solution.    

 

Query 2: I cannot find the way to pass a parameter in the event call, for instance ClientSideEvents(e => e.Change("onItemContainerChange(verify)")).And if I try to check args, args return the model value of the dropdownlist but it does not contain the object parent reference that triggers the event initially.
