[flexcoders] selectedIndices are Strings???
I dont understand why DataGrid.selectedIndices
returns an array of Strings. I thought that indices were generally integers. (For
example, Array.indexOf returns an int.)
Can anyone explain why the selected index of a DataGrid is a
String?
When dgTest is a DataGrid instance, the
following code generates a compiler error:
var arr:Array = dgTest.selectedIndices;
for(var i:int in arr){
// do something
}
The error that the compiler returns is as follows:
Implicit coercion of a value of type String to an
unrelated type int.

Try either of these two options: for( var i:int; i arr.length; i++ ) {trace( arr[i] ); } //or for each( var i:int in arr )
{trace( i ); }The for...in loop that you're using is for iterating over the properties of objects, which it expects to evaluate as strings. So, in your for...in loop, the var i refers to the indices of the array, not the values you're looking for which are the selectedIndices of your dg. The for...each loop above is new to AS3 and is the simplest way to do what you want.

RE: [flexcoders] selectedIndices are Strings???
Thanks Tom,
I believe array indices are ints, not
strings. However, I also believe that datagrid indices are strings, because
when I used the Array.sort() function on the DataGrid.selectedIndices array,
the order was all messed up. For example, 10 came before 2.
For that reason, I ended up writing a custom sort function to get around the
issue.
Thanks again!

RE: [flexcoders] selectedIndices are Strings???
Dont forget that the Array.sort()
method sorts using string values by default, so even when sorting an array of
numbers or ints, they will be sorted as if they were strings. To get numeric
sorting, so that 10 comes after 2, use the
Array.NUMERIC sort option, e.g.:
myArray.sort(Array.NUMERIC);
Heres the relevant example from the
ActionScript documentation for Array.sort():
The following code creates the Array object numbers
with elements [3,5,100,34,10]. A call to sort()
without any parameters sorts alphabetically, producing the undesired result [10,100,3,34,5].
To properly sort numeric values, you must pass the constant NUMERIC
to the sort() method, which sorts numbers
as follows: [3,5,10,34,100].
Note:
The default behavior of the sort()
function is to handle each entity as a string. The Array.NUMERIC
argument does not actually convert other data types to the Number data type; it
simply allows the sort algorithm to recognize numbers.
var numbers:Array = new Array(3,5,100,34,10);
trace(numbers); // 3,5,100,34,10
numbers.sort();
trace(numbers); // 10,100,3,34,5
numbers.sort(Array.NUMERIC);
trace(numbers); // 3,5,10,34,100

RE: [flexcoders] selectedIndices are Strings???
You know, I looked at that page in the
docs this morning, but I guess my eyes just skipped right past that part.
It seems decidedly counterintuitive, but I
should be used to that by now; Ive been developing Flash apps for 6
years!
Thank you for the help. Now I can go back
and simplify my code!
