https://community.esri.com/t5/python-questions/arcgis-pro-python-toolbox-stringinput-not/m-p/1201232#M65264 <P>Hello,<BR /><BR />I have an ugly behavior that is well known from web / HTML input scenarios where a text input field is triggering onChange only if the user unfocus the field of explicitly confirm the value with Enter. But often the developer needs to handle a user input right when it ocures.<BR /><BR />So in this case&nbsp;&nbsp;updateParameters is only triggered when I loose focus on my GPString input field not when the user writes new characters. Is it possible to get this onInput event? I need to show other fields based on the input text.<BR /><BR />Thank you for your help!</P> Wed, 10 Aug 2022 10:57:17 GMT RichardReinicke 2022-08-10T10:57:17Z https://community.esri.com/t5/python-questions/arcgis-pro-python-toolbox-stringinput-not/m-p/1201232#M65264 <P>Hello,<BR /><BR />I have an ugly behavior that is well known from web / HTML input scenarios where a text input field is triggering onChange only if the user unfocus the field of explicitly confirm the value with Enter.
