Hi Ravi,

Go through the following

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webdynpro/developi...

Follow the below steps:

1. Create a ValueAttribute "ChkGroup" and following valueattributes under the above valueattribute

check (boolean)

text (string)

2. Type the following in init() method

IPrivate<<VIEW>>.IChkGroupElement ele=wdContext.createChkGroupElement();

ele.setCheck(true);

ele.setText("1");

wdContext.nodeChkGroup().addElement(ele);

IPrivate<<VIEW>>.IChkGroupElement ele1=wdContext.createChkGroupElement();

ele1.setCheck(true);ele1.setText("11");

wdContext.nodeChkGroup().addElement(ele1);

3. Write the following in wdDoModifyView() method

IWDCheckBoxGroup grp1=(IWDCheckBoxGroup)view.createElement(IWDCheckBoxGroup.class,null);

grp1.bindTexts("ChkGroup.text");

grp1.bindEnabled("ChkGroup.check");

<<Container>>.addChild(grp1);

Hi,

Create a value attribute "checked" of type boolean.

Now try the following

IWDCheckBox cb1 = (IWDCheckBox)view.createElement (IWDCheckBox.class,null);

cb1.setText("Text");

cb1.bindChecked("checked");

"Checked" property is the one you need to makesure while creating the checkbox.This property should be bound to a valueattribute of type boolean

I am getting error.

And without binding to the context, can we eanble.

Because i want to create mulitple checkboxes.

Hi Ravi

No, You can't create CheckBox without binding to the context because it needs to save value of 'checked' property somewhere. Context is the only place for storing 'checked' property. The same is for RadioButton. You need to bind its 'selectedKey' property to the context.

If you need to create several check boxes dynamically you have to create dynamically the boolean attributes in the context too... and use them for binding.

Another possible way in your case is using CheckBoxGroup. The control will display required number of check boxes dunamically based on the number of elements in the context node bound to it. Let me if you need more info about the control.
