function

wddRoles_Initialize(sender, eventArgs){

alert(_wddRoles.get_items().get_length())

}

It is loaded by DataSource = DataTable.

hi,

what you have in your application is "get_length()", while i wrote "getLength()". These are two different functions. The first one  returns the actual number of CSOM javascript objects for the items - while the second one returns the size of the dom elements in the list - this is what you are looking for. When the control has AutoFiltering=Server and Off, there is automatic "Lazy Loading",  which means javascript objects  for the items are not created all at once, but on demand.

Thanks,

   Ok, All i what to do at this point is select the item in the list, client side.  It runs but nothing happens??

var items = _wddRoles.get_items();

var length = items.getLength();

var item;

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

item = items.getItem(i);

if (item.get_value() == txtPreviousRole.value) {

true);

   items.add(item);

   break;

}

Excellent....thanks.

Hi,

you can do item.select() to select it and have visual styles applied, and item.unselect() to remove styling and remove selected state . set_selected(true/false) only sets the internal CSOM state, that's useful if you want to select and postback, without having immediate styles applied visually.

There are actually a couple of shortcuts for client-side selection (dropdown is the control object, or "sender", as it is usually passed in client-side event handlers):

dropDown.selectItem(item);

dropDown.selectItemByIndex(itemIndex);

Hope it helps. Thanks,

Angel
