Hi

1) U can create UI elements dynamically in the wdDoModifyView().

2)For ex:If u want to create InputField dynamically

3)First get the ref of the container

IWDTransaparentContainer container=(IWDTransaparentContainer)view.getElement("id of container");

4)IWDInputField input=(IWDInputField)view.createElement(IWDInputField.class,null);

where view is the IWDVIew,which is one of the parameters of the wddoModifyView().

input.bindValue("cvar");

5)Add the inputfiled to the container

container.addChild(input);

6)For other elements see the following link

Hi,

Dynamic UI Element creation

We can create it only in the WD Modify View.

Get the instance for the Root UI Element Container.

Create the UI element Ex: Input Field, Text View etc.

Bind the UI Element to the Attribute Value.

Now bind the UI Element to the Root UI Element Container.

{

IWDTransparentContainer root =(IWDTransparentContainer)view.getRootElement();

IWDInputField InpName = (IWDInputField)view.createElement(IWDInputField.class,"InpName");

IWDInputField InpAge = (IWDInputField)view.createElement(IWDInputField.class,"InpAge");

IWDInputField InpGender = (IWDInputField)view.createElement(IWDInputField.class,"InpGender");

IWDNode Mad =wdContext.getChildNode("Person",0);

IWDAttributeInfo NameAtt = Mad.getNodeInfo().getAttribute("Name");

IWDAttributeInfo AgeAtt = Mad.getNodeInfo().getAttribute("Age");

IWDAttributeInfo GenderAtt = Mad.getNodeInfo().getAttribute("Gender");

InpName.bindValue(NameAtt);

InpAge.bindValue(AgeAtt);

InpGender.bindValue(GenderAtt);

root.addChild(InpName);

root.addChild(InpAge);

root.addChild(InpGender);

}

Dynamic Action Creation

Create the Action in the Action tab.

Create a Button.

Get the reference for the created action (Through the Event Handler).

Bind the Action to the Button.

Bind the Button to the Root UI element Container.

IWDButton ButGo = (IWDButton)view.createElement(IWDButton.class,"ButGo");

IWDAction ActGo = wdThis.wdCreateAction(IPrivateStartView.WDActionEventHandler.GO,"Click");

ButGo.setOnAction(ActGo);

root.addChild(ButGo);

Now write the required code for the Event Handler that is associated with the Action.

//@@begin onActionGo(ServerEvent)

IWDNode Mad = wdContext.getChildNode("Person",0);

wdComponentAPI.getMessageManager().reportSuccess(Mad.getCurrentElement().getAttributeAsText("Name"));

wdComponentAPI.getMessageManager().reportSuccess(Mad.getCurrentElement().getAttributeAsText("Age"));

wdComponentAPI.getMessageManager().reportSuccess(Mad.getCurrentElement().getAttributeAsText("Gender"));

//@@end

Hope it helps,
