Hi,

Yes we can not tell our users start guessing what are the selection in our drop down boxes. As i have discussed it with your other members. We have huge websites that uses some pages could use unlimited drop down with checkboxes. At the moment we are using ajax and modal popup. I have checked other suppliers of asp.net controls and they are do support such controls but as we been checking your controls for the last few years and there are other controls we can use. But this is the main one for us.

We have already over 50,000 users we can not just change our page design remove drop selection and give me the a text box to type in text. All what needs to be done is just new property that allow first time load on demand when you click on the arraow down of radcombobox then the next time will load it from the cached copy. 

Please let us know

Thanks
