Hi Rohan,

1. set the keyToSelect =key forradiobutton

2. Bind a context of type string to the selectedKey property of the radiobuttons name selectedradiobutton.

3. Create actions for all the buttons and bind them to their respective buttons.

4. In implementation you can check which radio button is selected using

if(wdContext.currentContextElement().getSelectedRB().equals("key_1"));

There are the 3 preperties maily used in of radiobutton.

KeyToSelect: Unique key which will be identified while selection from a number of radiobutton.s

SelectedKey: This is used set to the key of the radiobutton that is currently selected.

OnSelect: An event that you want to fire when the radio button is selected.

Rest each button is having a different action so you can open the document you want just checking which RB is selected.

if u want more information about Radio button go to this

hi manivanan,

yes what you are saying is to check wether it is clicked or not but i require the button to be set clicked when the view is opened for the first time.

for example i have 4 radio buttons where b is the default clicked

a b. c d

so when i open the view i can see that b is already selected

how do i code for this.

hi,

If you are using radiobuttongroupbykey, then its selectedKey property must be bounded to a attribute of simpleType.

In wdDoInit(), set this attribute to the key which you want to display as checked by default.

Hi,

Use this code

create 2 attributes

1.Radio_activity

2.Sel_Value

wdContext.currentContextElement().setRadio_activity("b");

wdContext.currentContextElement().setSel_value(wdContext.currentContextElement().getRadio_activity());

go to properties assign the value keytoSelect -

---

>SelValue

selectedKey--->RadioActivity
