Miguel,
Compare function1 with the one you sent. Notice, that I have
"dg.getItemAt(i)" instead of "dg.getItemAt(i+1)" and you can get specific
value from the column by giving the column Name like "dg.getItemAt(i).code"
When you do dg.getItemAt(i), it returns you the entire row row for that
index. The row is an object containing all the columns you have in the
dataprovider of the datagrid.
=======Function 1==================================================
function envia_motivos_fuc(){
var Request:Object = new Object();
var selectedData:Array = new Array();
for(var i=0;i<dg.length;i++) ----> dg is datagrid�s name
{
if(dg.getItemAt(i).select)
{
Request.para = dg.getItemAt(i).code ----> here i�m specified a
parameter
servicio_datos_motivos.send(Request); ----> that�s webservice
}
}
}
=========================================================
One more thing that it'll work if you select only one checkbox in the grid
but if you're doing multiple selections from the checkbox then it'll create
problems since for every single selected checkbox, you're sending single
value to the webservice. It'll make a lot more sense if you populate an
array with all the selected items and send that array to the server.
function envia_motivos_fuc()
{
var Request:Object = new Object();
var selectedData:Array = new Array();
for(var i=0;i<dg.length;i++) ----> dg is datagrid�s name
{
if(dg.getItemAt(i).select)
{
selectedData.push( dg.getItemAt(i).code );
}
}
Request.para = selectedData ----> here i�m specified a parameter
servicio_datos_motivos.send(Request); ----> that�s webservice
}
This way you send any array with all the selected codes at once, which makes
it easier to manage. Let me know if you have any question.

Subject: [flexcoders] Re: how can I do this in Flex? -- (warning, best

mmm, i have a question now, how can i get only one column of a row i need to
send it how a parameter, but no all row, only a column
for example
|___select one___|___code___|___name___|
■ 101 name 1
■ 102 name 2
■ 103 name 3
supposing that I select the second row, I want to take code only, that is to
say, " 102", and this value I want to send it as parameter through an aspx
file across a webservice (which is already done)
my another problem is I do not know if the function to extract the value is
realized well
that�s code:
function envia_motivos_fuc(){
var Request:Object = new Object();
var selectedData:Array = new Array();
for(var i=0;i<dg.length;i++) ----> dg is datagrid�s name
{
if(dg.getItemAt(i+1).select)
{
Request.para = dg.getItemAt(i).rowIndex(i+1) ----> here i�m
specified a parameter
servicio_datos_motivos.send(Request); ----> that�s webservice
}
}
}
thanks in advance for all help
