Slider onChange event is not triggering when slider value change through variable

Hello,

I am currently developing a Custom Page and utilizing the default (classic) controls. My goal is to activate the OnChange event of a Slider control whenever its value is altered via a context variable.

However, the OnChange event only activates manually. When attempting to change the slider value through the context variable, the event does not trigger at all.

For my use case, I need the functionality where any change in a textbox value prompts a call to an API using the new text.

Thank you for your assistance.

@Jitendra_FT ,

If you set the OnChange to your desired formula. You can try to use Reset() function to call the API, it will be classed as "Change" in your slider in theory.

At least if you use the OnChange formula
UpdateContext({API:!API})
It changes the value to false and true every time you Reset the Slider. So you can try to use this concept.

Hi @Gochix

Thanks for your response.

I don't have a way to call Reset() function while user is still typing. I was thinking I would change the value property of slider (length of typed string in Textbox) which eventually triggers the OnChange event of Slider.

Currently, I'm playing with Timer control, I hope it would work.

Thanks
