CheckBoxGruop - SingleSelection

[Former Member]

Hi,

i have implemented a checkBoxGroup. I thought that in a group only one value can be selected?

But in my Gruop every CheckBoxField can be selected. I want that only one field can checked and if an other get selected the first field is unselected and the new one is selected.

String[] values = {Value_1,Value_2,Value_3,...}; 
                
             for (int i = 0; i < values.length; i++) { 
                        IWDNodeElement elem = wdContext.nodeNodeName().createElement(); 
                        elem.setAttributeValue("attName", values<i>); 
                        
                        wdContext.nodeName().addElement(elem); 
                }

What you are looking for is called RadioButtonGroupBy{Index,Key}.

Thanks, thats works fine. But is it possible to change the appereans?

So that first the label an than the radionButton appears.

I haven't found an attribute for this

No you cannot change that via the Web Dynpro API.

Hi,

You can use radioButtonGroup which is more appropriate for your scenario as Armin said.

But for your purpose here is the solution:

1. Create two global variables ie in others section of the implementation tab as:

public static int j = 0;
public static boolean flag = false; 

2. Create an action gor your CheckBoxGroup ie onToggle and implement it as:

if(flag){
   wdContext.nodeMonthsOfYear().setSelected(j, false);	
// Here MonthsOfYear is the node containing the attribute mapped to your checkBoxGroup texts property
   
} 

Thats it.

Hope this helps.

thanks & regards,

Manoj

Hi Armin,

I know this is bad advice.

But just to correct my previous reply, i missed some points there. I went to edit that reply but it is showing i cant do that.

Hence, i am posting the same here. Just for sake of correctness.

For SAP User :

I missed the complete solution in my previous reply. Well offcourse you can ignore the solution as it is really not proper to use this solution for your purpose.

if(flag){
   wdContext.nodeMonthsOfYear().setSelected(j, false);	
// Here MonthsOfYear is the node containing the attribute mapped to your checkBoxGroup texts property
   
} 

3. In wdDoModify() write:

for(int i = 0;i<wdContext.nodeMonthsOfYear().size();i++){

if(wdContext.nodeMonthsOfYear().isMultiSelected(i)){

flag = true;

j = i;

break;

}

}

Thats it.

Hope this helps.

Still bad advice Think about what "static" means.

Apart from that, why should he use such a crappy workaround if there is a UI element that exactly fulfils the requirement (1-from-n selection)?
