accessing webforms-listbox from clientside jscript

[RFS666]

Hello together,

I wanted to ask if somebody can help me with accessing a listbox (a
serverside webform from the designer-toolbox) from clientside JScript. I need
to add and remove values and find out about the selected index.

I hope somebody can help & thanks in advance

To add a value (listitem):
var list = document.getEle mentById ("ListBox1") ;
if (list)
{
alert("selected Index= " + list.selectedIn dex;
var option= document.create Element ("option");
list.options.ap pendChild(optio n);
var txt = document.getEle mentById ("txtListItem") ;
option.text=txt .value;
}

The ListBox server control renders an HTML select object on the browser. To
manipulate it using JScript (or Javascript) use the options collection of the
HTML SELECT object. There is a "remove" method for the options collection.

For a sample on managing the viewstate of ListBox server control on the
browser: http://www.societopia.net/samples/li...lientside.aspx
