deselecting the radio buttons

[Former Member]

Hi,

I am creating the radio buttons dynamically in the following way

String answers[] = qForm.getAnswers();

for (int j=0;j<qForm.getNoOfChoices();j++)

{

IWDRadioButton radio =

(IWDRadioButton)view.createElement(IWDRadioButton.class , "radio"ij);

radio.setText(answers[j]);

wdContext.getNodeInfo().addAttribute("radio"ij,"ddic:com.sap.dictionary.string");

radio.bindKeyToSelect("radio"ij);

radio.bindSelectedKey("radio"ij);

rootContainer.addChild(radio);

}

<b>but what is the problem is when i access the view all the radio buttons are selected by default which i donot want to happen.and how do i know which radio button is selected when i select any one.

Please let me know what are the various options</b>

Radio buttons must be bound to the same context attribute to realize the "radio button" behavior.

Why do you want to do all this by code instead by using the IDE?

Create a context attribute named "selectedKey", type=string, at design-time.

String answers[] = qForm.getAnswers();
for (int j=0; j < qForm.getNoOfChoices(); j++)
{
  IWDRadioButton radio =
(IWDRadioButton) view.createElement(IWDRadioButton.class , null);
  radio.setText(answers[j]);
  radio.setKeyToSelect(String.valueOf(j));
  radio.bindSelectedKey("selectedKey");
  rootContainer.addChild(radio);
}
/* select first button */
wdContext.currentContextElement().setSelectedKey("0");

Hi Armin,

what does this mean

Hi,

wdContext.getNodeInfo().addAttribute("radio1","ddic:com.sap.dictionary.string");

for (int j=0;j<qForm.getNoOfChoices();j++)

{

IWDRadioButton radio =

(IWDRadioButton)view.createElement(IWDRadioButton.class , "radio"ij);

radio.setText(answers[j]);

radio.setKeyToSelect("radio"ij);

radio.bindSelectedKey(radio1);

rootContainer.addChild(radio);

}

wdContext.currentContextElement.setAttribute("radio1",radio11);//key that you want to be selected by default.

Hi Murtuza,

This is not working for me and here is what i wrote

wdContext.getNodeInfo().addAttribute("radio1","ddic:com.sap.dictionary.string");

for (int j=0;j<qForm.getNoOfChoices();j++)

{

IWDRadioButton radio =

(IWDRadioButton)view.createElement(IWDRadioButton.class , "radio"ij);

radio.setText(answers[j]);

radio.setKeyToSelect("radio"ij);

radio.bindSelectedKey("radio"ij);

rootContainer.addChild(radio);

}

wdContext.currentContextElement().setAttributeValue("radio1","radio"i0);//key that you want to be selected by default.

and this is the error i am getting

<b>com.sap.tc.webdynpro.progmodel.context.ContextException: DataNodeInfo(SCJP): unknown child node radio00 </b>

any other thoughts

Hi Bala,

You have changed a line in the code mentioned:

<b>radio.bindSelectedKey(radio1);</b>

wdContext.getNodeInfo().addAttribute("radio1","ddic:com.sap.dictionary.string");

for (int j=0;j<qForm.getNoOfChoices();j++)

{

IWDRadioButton radio =

(IWDRadioButton)view.createElement(IWDRadioButton.class , "radio"ij);

radio.setText(answers[j]);

radio.setKeyToSelect("radio"ij);

<b>//radio.bindSelectedKey("radio"ij);</b>

<b>radio.bindSelectedKey(radio1);</b>

rootContainer.addChild(radio);

}

wdContext.currentContextElement().setAttributeValue("radio1","radio"i0);

Hi Murtuza,

I didnot understand where this <b>radio1 </b>is coming from

[Former Member]

Hi,

radio1 is the attribute that we have added dynamically in the code itself. Just refer the first line of your code.

Hi Murtuza,

<b>I am sorry i didnot mention radio1 initially . after u sent me the below code snippet I modified a little bit but still it is not working </b>

wdContext.getNodeInfo().addAttribute("radio1","ddic:com.sap.dictionary.string");

for (int j=0;j<qForm.getNoOfChoices();j++)

{

IWDRadioButton radio =

(IWDRadioButton)view.createElement(IWDRadioButton.class , "radio"ij);

radio.setText(answers[j]);

radio.setKeyToSelect("radio"ij);

radio.bindSelectedKey(radio1);

rootContainer.addChild(radio);

}

wdContext.currentContextElement.setAttribute("radio1",radio11);//key that you want to be selected by default.

But anyways i got the working code from armin but still i need to do a lot like

<b>I am generating four checkboxes and one button dynamically .I will check some checkboxes and on the click of the button i want to capture what checkboxes have been checked and need to do the same thing for radio buttons</b>

any thoughts on this

Hi,

For radio button you can check the value of the context binded to the selectedKey to know the currently selected radio button.

But for checkbox group, you will have a node to loop around and check whether it is selected or not.

wdContext.node<nodename>().isMultiSelected();

even this option is not of much help.on the loading of the view all the radio buttons are selected by default.

any other ways of doing this
