Hi sabeer,

if you want to change your default view when you click on button..so you need to some code written in WddoModify

in

public static void wdDoModifyView(IPrivateCheckView wdThis, IPrivateCheckView.IContextNode wdContext, com.sap.tc.webdynpro.progmodel.api.IWDView view, boolean firstTime)

{

urView=view;

}

declare in view..at

//<@other begin

static IWDView urView=null;

//<@end

crate one action for button like

public void onActionShowChange(event){

//TextView1--id of textview Ui element

IWDTextView text=(IWDTextView) urView.getElement("TextView");

text.setText("you choice massage");

}

this action assign your button..

hope this will work

thanks

I hope you didn't use the proposal with the static view reference (this will not work). Use the solution with data binding to context attribute.

Hi Shabbir

You have hard coded the "Hello world" in the text property of your "TEXT VIEW" UI element.

Thats not the procedure to change the text of above UI element when user is pressed a button.

Create a context attr in the context and bind with the text property of the UI element.

Create an action and bind with the onAction event of a button

In the action property change the value like

wdContext.currentContextElement().set<ATTRIBUTE NAME>("Your Custom Value");

Hello Shabeer,

Hope you have created an Action and bind it to the button.

Create an attribute in your context and bind that to the text UI element of the default view.

In onAction<action> method change the text of the context attribute. It will get reflected in your view when you press the button.

Hope this helps.

Hi Shabeer,

Bind you TextView UI element to the context attribute and change the value on the action of Button by setting the value to a context attribute.

Hi Shabeer.

Did U bind Ur button with an action?

If yes, write the below code in Ur onAction<buttonAction> method.

wdContext.currentContextElement.set<attributeName> ("New text");

Hope this helps,
