I am writing code that needs a box like the ComboBox but with different functionality. Can someone tell me how to accomplish this? (either with ComboBox or some other Rad control)
Users will type text they wish to search for in a textbox/combobox type field. I want it to give common (preset and known) choices that match what they are typing as they type (Like ComboBox Filter function). If what they wish to type is in the list that appears, I want the user to be able to select it. So far, this is just like the ComboBox, but here is the hitch. If what they type is not in the list I want to return the text they type. I do not want to require them to select form the preselected list, I just want it to help them from what others have searched for in the past.
I hope I said this clearly enough. I appreciate your help.

Hi Paul,
The scenario described, could be achieved trough the client-side API or server-side API of the RadComboBox. In both cases you could use the TextChanged event.
Below is an example of how the described scenario could be achieved with the client-side event OnClientTextChange:
To see how to use the server-side event OnTextChanged, you could refer to the following link: RadComboBox / OnTextChanged.
I hope this helps.
Kind regards,

function OnClientTextChange(sender, args){ var textTyped = sender.get_text();//Gets the typed text in the input field.
if (sender.findItemByText(textTyped) == null) { //Do something with the text typed in the input field. } else { //The user has typed a text which corresponds to an item. }}To see how to use the server-side event OnTextChanged, you could refer to the following link: RadComboBox / OnTextChanged.
I hope this helps.

It turned out while this answer is correct and very helpful, the only thing I needed to do was set
AllowCustomText="true"
this returns a Value of ""
and Text of whatever the user typed or selected (in which case the value is the associated value).
This was all I needed. So if anyone reading this thread wanted the user to be able to type in text and return it in the combo box even if nothing is selected, AllowCustomText="true" is your answer. If you need to manipulate the results, use what Ivana said.
Both are very good solutions.
Thank you,
