hi all
i have problem with requestItems() method in Radcombobox .it causes postback page and captcha generates new code but not shows it to user .i searched forum and you suggest use
RadXmlHttpPanel but how can i change this code :
<script type="text/javascript">
//global variables for the countries and cities comboboxes
var countriesCombo;
var citiesCombo;
function pageLoad()
{
// initialize the global variables
// in this event all client objects
// are already created and initialized
countriesCombo = $find("<%= RadComboBox2.ClientID %>");
citiesCombo = $find("<%= RadComboBox3.ClientID %>");
}
function LoadCountries(sender, eventArgs)
{
var item = eventArgs.get_item();
countriesCombo.set_text("Loading...");
citiesCombo.clearSelection();
// if a continent is selected
if (item.get_index() > 0)
{
// this will fire the ItemsRequested event of the
// countries combobox passing the continentID as a parameter
countriesCombo.requestItems(item.get_value(), false);
}
else
{
// the -Select a continent- item was chosen
countriesCombo.set_text(" ");
countriesCombo.clearItems();
citiesCombo.set_text(" ");
citiesCombo.clearItems();
}
}
function LoadCities(sender, eventArgs)
{
var item = eventArgs.get_item();
citiesCombo.set_text("Loading...");
// this will fire the ItemsRequested event of the
// cities combobox passing the countryID as a parameter
citiesCombo.requestItems(item.get_value(), false);
}
function ItemsLoaded(sender, eventArgs)
{
if (sender.get_items().get_count() > 0) {
// pre-select the first item
sender.set_text(sender.get_items().getItem(0).get_text());
sender.get_items().getItem(0).highlight();
}
sender.showDropDown();
}
</script>
i don't want captcha changes code when items load on comboboxes?
thanks
