Hi Mani,
Sorry for the delay in responding to your question. I cannot think of an easy way to do this, for Treeview isn't based on a control that supports multiple-select such as Listbox. Have you considered using checkboxes as leaves/values to simulate multiple selecting?

Cheers!
Kirupa :)

hi kirupa
how to validate duplicate usernames so that unique values get entered in the listbox

You can use a Dictionary to store all of the current values, and when a new value is entered, check your Dictionary to make sure that value isn't still there :)

hi kirupa thanks for replying
here is the code



var my_list:mx.controls.List;
user.text = "";
btn1.onPress = function ()
{
if (user.text == "")
{
error = "please enter name";
}

if (user.text != "")
{
for(i=0;i<my_lb.length;i++)
{
nite=my_lb.getItemAt(i).label;
trace(nite);

}
if(user.text == nite)
{
trace("Duplicate Values");
}
else
{
trace("OK");
my_lb.addItem(user.text);
}
user.text = ""
error = "";
}

}

btn2.onPress = function () {
//mydata = my_lb.length;
var myA=new Array();
myA=[];

for(i=0;i<my_lb.length;i++)
{
//trace(my_lb.getItemAt(i).label);
myA.push(my_lb.getItemAt(i).label);
//trace(myA);
}

mydata=myA;

}



btn3.onPress=function()
{
if (my_lb.selectedIndex != undefined)
{
my_lb.removeItemAt(my_lb.selectedIndex);
error="";
}
else
{
error = "please select something in list";
}

}
