ComboBox maxLength property
We have database constraints on certain fields e.g. varchar(10) and would like to prevent the user from entering invalid data into the combo box fields. If it's not too much trouble a minLength field would also be convenient.

Hello, Brent,

Thank you for sharing this approach with the KendoReact community.

I'm sure it will prove helpful to others.

in case it helps others landing here... for us, managing the combobox filter prop got into too much dependency with the value prop... we went with DOM manipulation to simply set the native <input maxLength>... DOM is of course frowned upon with React but avoided significantly more complexity.

rough sample:

export const MyPageComponent: React.FC = () => {
    const comboRef = useRef(null);
    useEffect(() => {
        const nativeInput = (ReactDOM.findDOMNode(comboRef.current) as HTMLElement)?.querySelector('input');
        nativeInput && (nativeInput.maxLength = comboMaxLength);
        // eslint-disable-next-line react-hooks/exhaustive-deps

    }, []);

return <div>

<ComboBox
     ref={comboRef}
        allowCustom={true}
// ... etc...
/>

</div>;
}

Hello,

We have a demo demonstrating how this can be done:
