Hi Yukiko,
Thank you for contacting Syncfusion support.
We have analyzed your query and provided sample at our end. For your provided sample, we were unable to find which place you have rendered the ejCurrencyTextbox component in your application. In our currency text box, minimum value is 0 by default. So, to set the negative value please change the minValue of element. Please refer the below code snippet
$("#currency").ejCurrencyTextbox({
name: "currency",
value: 555,
minValue: -100,
}); |
Still you are facing the same, please provide more details about your requirement. This would be more helpful to identify your problem easily.
Thanks,
Christo
