Widget that will allow users to add weights and change the symbology of a feature layer

Question asked by drewm0520 on Aug 18, 2016



I am putting together a web app and would like to add a widget that updates the xml data of a feature layer based on input from a user and then symbolizes the polygons based on the re-calculated data. For example, if a feature has a value of 2 in the field "Cost", and the user inputs 3 into the form, the new value for the "Cost" field would be 5 and color coded based on set value ranges (0-3,4-7, etc.). Essentially I would like the user to be able to see the symbology change on screen as they input new weights without having edit rights to the feature layer itself.
