    We're using RadAutoCompleteBox together with a FilteringBehavior, to filter a very large dataset.

    We don't necessarily want to fire the filtering after every key press, because there is no point in that if the user is still typing.

    Is there any way to add a small delay, so that the filtering mechanism is only fired if the search text hasn't changed for 500 milliseconds?

    Hello,

    In the current version of RadAutoCompleteBox there isn't a FilterDelay built-in feature that could be used.

    Hello,

    Is this feature now avaiable or do you have a workaround to achieve this?

    Hello Jeremy,

    RadAutoCompleteBox does not provide the desired by you functionality our of the box. However, we have a sample project that demonstrates how to implement such minimum delay before the built-in filtering of the control is triggered - the sample you could find in our online SDK Repository:
    https://github.com/telerik/xaml-sdk/tree/master/AutoCompleteBox/MinimumPopulateDelay

    We hope this will help you.
