Only allow RadSearchBox selection to be one of the listed options

[Adam]

I have a RadSearchBox.  The user can start typing and a list of selections comes up.

Is there a way I can restrict the user from typing in invalid choices?  I want to force them to choose one of the items on the list.

Any ideas on the best way to approach this would be appreciated!

Hello Adam,

We have created a KB article that covers this scenario - Ensures an item is selected when searching with SearchBox. 

<telerik:RadSearchBox HighlightFirstMatch="true"  OnClientLoad="OnClientLoad" ... >
</telerik:RadSearchBox>

<script>
    function OnClientLoad(sender, args) {
        // clear the text if there is no selected item
        if (!sender._highlightedItem) {
            sender.get_inputElement().value = "";
        }
    }
    function OnClientSearch(sender, args) {
        // prevent postback if no item is selected
        if (!sender._highlightedItem) {
            sender._postBackOnSearch = false
        } else {
            sender._postBackOnSearch = true
        }
    }
</script>
