I developed an app, where my users need to upload their shapefiles through the add data widget. When they upload their shapefile, each time it shows the polygon with a random style! For example, when I upload a shapefile, once it shows it with a solid pink, once with solid red, etc.
My question is how a user can change the style of shape file after uploading it?
How we can standardize the formate of shapefiles which users will upload? for example, I need it would be always red polygons.
