Change color of formatting option input field on validation

[WouterBo]

Hi,

When a user enters a range (start and end values) in the formatting options for an axis, I want to be able to indicate an input error by changing the border color of the input fields. For instance: if the start value is greater than the end value, I want the end value input field to change its border color to red.

How can I do this is custom visuals?

Hello @Sujit_Thakur ,

I'm not sure I can show you in Excel, but I've included a picture of the desired effect. What you are looking at are the formatting options for a custom visual. The "End" value here is lower than the "Start" value and the "End" field's border is colored red. How can I achieve this in my own visual?
