WD ABAP: How to use checkboxes in webdynpro for abap

Question

Hello all,
I want to use a group of Radio-Buttons in my Webdynpro. If I use the element RadioButtonByKey it will shown three Radiobuttons, how can I use them? I think I have to bind every Radiobutton on an seperate Context-Attribut. But I didn´t know can I do this. And why there are always three Radio-Buttons? I need only two. Is there anywhere a Tutorial which describes the handling of the Radio-Buttons?
Kind regards
Axel

Hi Axel,
  if u need two radio buttons then insert child of type radio button .here is th simple example for creating and binding the buttons to selction key.
Example:
Assume that u r having 2 Radio buttons R1 and R2.
For this u create 3 attributes R1,R2 and Sel.
For the radio button R1:
set the element properties as:
keytoselect---R1
selected key --Sel
For the radio button R2:
set the element properties as:
keytoselect---R2
selected key --Sel
In implementation part :
public void wdDoInit()
//@@begin wdDoInit()
wdContext.currentContextElement().setR1("Pass");
wdContext.currentContextElement().setR2("Fail");
wdContext.currentContextElement().setSel("Pass");
//@@end
SO from the above code the default radio button R1 will be enabled.
If u want the second radio button to be default then change sel to
wdContext.currentContextElement().setSel("Fail");
so during run time when u select the first one automatically its selvalue changes according to the radio button's value.
