RadListBox insertItem

[Dave Hollen]

Hello,

I am trying to user the insertItem function (in Javascript) for the RadListBox. 

Here is my code:

var

 

listBox = $find("<%= rlbSelectedContacts.ClientID %>");

 

 

var arr = [];

 

 

for (var i = 0; i < 10; i++) {

 

 

var item = new Telerik.Web.UI.RadListBoxItem();

 

item.set_text(

"text" + i);

 

arr[i] = item;

}

listBox.insertItems(arr);

When I run this script, it is telling me that "Microsoft JScript runtime error: Object doesn't support this property or method" regarding the insertItems() function.  listBox is not NULL in my script.  Any ideas?

I need to insert 2000+ items into the list box and a bulk insert would do wonders.

Thanks!
Dave

Hello Dave,

I've tested this code and it worked without a problem at our side. Which version of the controls you're using?
