Hi,
I am adding some values to the ASP.NET ListControl on the client side
javascript
and this is not reflecting on the server side.
I thought the input and select fields should reflect the changes on
the server side.
I know that the post backs doesn't post all of the HTML only the
changes etc,etc.
I am adding so many values to the list on the client side so I can't
have an hidden input field.
That will make things complex.
Any ideas?
Below is the javascript code,
function OnClientClick_btnAdd()
{
var listReomveFrom = document.getElementById("ctl00$MainContent
$ListBoxAvailable");
var listAddTo= document.getElementById("ctl00$MainContent
$ListBoxSelected");
var iCurrentIndex = listReomveFrom.selectedIndex;
var iNewOptionIndex = listAddTo.length;
if (iCurrentIndex != -1)
{
listAddTo.options[iNewOptionIndex] = new Option();
listAddTo.options[iNewOptionIndex].text =
listReomveFrom.options[iCurrentIndex].text;
listAddTo.options[iNewOptionIndex].value =
listReomveFrom.options[iCurrentIndex].value;
listAddTo.options[iNewOptionIndex].selected =
listReomveFrom.options[iCurrentIndex].selected;
listReomveFrom.options[iCurrentIndex --] = null;
}
}
Thanks,

the browser only posts back the selected value(s) of a <select>, not the
list. you will need to pass the changes back with some other method (say
a hidden field).
