DropDownbox Value Access

[Former Member]

Hi,

I am creating a webdynpro application where i have a dropdownbox in a view with some values. I have a local variable which receives the value selected from the drop down. How can i pass this value to the Component Controller Variable? Does anyone have code samples for passing value from a local context variable to the component controller variable?

Regards,

Hi Divya ,

You could access the Drop Down Selected and directly pass it to Context Variable as below

wdContext.currentContextElement().setW2Year(wdContext.nodeW2Node().getLeadSelection(

If u feel this helped u , xxxxxxxxxxx.

Hi Divya,

Write a function in comp controller taking one parameter. From view u can call comp controller function by passing that value.

Create the variable in the component controller and then map to the view.

Todo the above mentioned you dont need any code.

Ex:

Component Controller -> View Controller -> View

Attribute x Mapped-> Attribute x -> Bind to the UI Element.

Hi,

You can do it in two ways:

1) You can map a context attribute to your view via Component Controller. Set the value for this attribute and access it in your Component Controller.

2) You can set a context attribute of Component Controller using the following code from your view.

wdThis.wdGet<Controller Name>Controller().wdGetContext().currentContextElement().set<Attr Name>();

But for this also, your view must be mapped to the Component controller, not necessarily the attribute which you want to set.

thanks & regards,

Hi Divya

1) Bind the component controller context into the view [say Sample is the name of context node]

2) now wdContext.currentSampleElement.set<your attribute vallue>(your dropdown value)
