Hello Mihir,

It has been a while since you have made your post, in case you still need support I will be glad to assist you further. I suppose the other community members can benefit from this answer as well. I have been looking through your post and I created a sample project for you with a custom separate ToolTip for each Field in the FieldChooser. Basically I copied the default style for the FieldChooser and add a ToolTip in it and using a Converter I return different values depending on the Field’s Name.

Feel free to write me if you have further questions.
