OnClientItemsRequestingHandler issue: sender._cachedText is blank

[nk]

I've handled OnClientItemsRequesting for radComboBox. Below is the handler code.

function OnClientItemsRequestingHandler(sender, eventArgs)
{
    if (sender._cachedText != unescape(sender._callbacktext))
    {
        sender.clearItems();
    }
}

I'm clearing out all items from the combobox before callback if the search text has changed since last callback.
sender._cachedText gives current value entered for search in combobox
sender._callbacktext gives last callback value.
I get the intended behavior in IE all versions.Whne user changes searchtext, items are cleared (as both the text are different). When user clicks on More Results box, the items are not cleared (as both the text are same)

When in Firefox, sender._cachedText  is always empty. Cant figure out why.

Hi nk,

The _cachedText is initialized in a different way under Internet Explorer and Firefox and this is by design.
Let me suggest you use the sender._originalText and sender.get_text() instead.

Kind regards,

I've used eventArgs.get_text()
