Hide empty dropdown

[John Hadjioannou]

I would like to hide the dropdown when it is empty - how could that be achieved?

Ideally, I would like to reduce it's size to match the contents if there is empty space at the bottom - but that may be too difficult.

Thanks
John

Hi,

You can cancel the 'OnClientDropDownOpening' by using the code "args.set_cancel(true)" if there are no items in the RadComboBoxItems collection. You can check the number of items from client-side. The following documentation will help you in achieving this:
Client-Side Basics
RadComboBox object

Also checkout the following forum which discussed about setting the dropdownwidth according to items.
