Dynamic checkbox names

Hello,

I have around 70 checkboxes in my AIR application, which all have names like: c1 - c70 (this means that first checkbox has id="c1" , second id="c2"..... id="c70")

Now i would like to check all 70 checkboxies and determine which one is selected and which one is not.  I would like to use one for loop because it would be too much to write 70 if conditions to check all that manualy.

//here you go... 3 for the price of 1 ;o)

CheckBox(CompCheckBox.getChildByName('c'+(i+1))).selected

create an array to hold the controls

var checkBoxes:Array = new Array();
checkBoxes.push(new Checkbox());

//access like this
checkBoxes[69].checked = true;

//loop round like this
for (var i:int = 0;i<checkBoxes.length; i ++){
   checkBoxes[i].checked = true;
}

Hmm, i don't think that i understand your solution...

I will try to explain what i need one more time:

I have one Flex (AIR) application in which i have 70 Checkboxies, when user press one button i want to check state of those 70 checkboxies with one loop. Because of that i gave namese to those checkboxies from c1 - c70

Are the checkboxes created using actionscript?
example
var c1:Checkbox = new Checkbox();
or at design time by draggin them onto the stage?

either way.. to loop through them you will need to insert them into an array
var checkBoxes:Array = new Array();
checkBoxes.push(c1);
checkBoxes.push(c2);
checkBoxes.push(c3); ///etc..

then you can loop through as-per the exmple i gave in the above post.

Actually if you added at design time and gave instance names via the properties panel just use
for (var i=0;i<70;i++){      
     CheckBox(getChildByName('c'+(i+1))).selected= true;
}

Ok tnx, it seems that it is working. But just can you tell me one more think:

In some cases there will not always be c1 -  c70 , mybe some times there will be missing c2 or c43...
So is there a way to first check if checkbox with specific ID exists and then to manipulate it.

If i don't check it i will get   null object reference  error

//try this

for (var i=0;i<70;i++){    
 if(getChildByName('c'+(i+1)) ){
     CheckBox(getChildByName('c'+(i+1))).selected= true;
  }
}

Tnx, that is great.

And if it is not big problem for you, can you please tell me how following line will looklike for chechbox that is located in component file (which i include in main file and give it id="CompCheckBox")

 CheckBox(getChildByName('c'+(i+1))).selected


in "noraml" - manual access to each checkbox i would use
CompCheckBox.c1.selected .....

Tnx in advance!
