Data Collection .NET

Data Collection for .NET shows how a robust application can be built with the ArcGIS Platform using the ArcGIS Runtime SDK for .NET, WPF, and UWP. It demonstrates best practices around some simple but key functionality of the ArcGIS Runtime. Using your organization's web maps, you can use Data Collection as-is, or extend it to meet your specific needs.

  • Take your web map and data offline
  • Edit your data both offline and online
  • Synchronize offline edits
  • View and edit your data with Popups
  • Work with Features, Popups, Attachments, and PopupManager
  • Edit and query Feature Tables
  • Work with related records
  • Identify map features
  • Authenticate with Portal using OAuth
  • Use the World Geocoder service
  • Use Popup configuration to drive app behavior
  • Navigate to bookmarks defined in the web map
  • Show and hide layers with a table of contents
  • View symbology for layers in the map with a legend

Best practices

The project also demonstrates some patterns for building real-world apps around the ArcGIS Runtime SDK.

  • Map-centric UI design
  • ArcGIS asynchronous service pattern
  • Cross-platform application design
  • Model-View-ViewModel pattern

Detailed Documentation

Read the docs for a detailed explanation of the application, including its architecture and how it leverages the ArcGIS platform, as well as how you can begin using the app right away.

Get started

You will need Visual Studio 2017 or later (2019 or later is recommended).

Fork the repo

Fork the Data Collection repo.

Clone the repo

Once you have forked the repo, you can make a clone and open DataCollection.sln in Visual Studio.

Command line Git

  1. Clone Data Collection
  2. cd into into the cloned repository's directory
  3. Make your changes and create a pull request

Configuring a Remote for a Fork

If you make changes in the fork and would like to sync those changes with the upstream repository, you must first configure the remote. This will be required when you have created local branches and would like to make a pull request to your upstream branch.

  1. In the Terminal (for Mac users) or command prompt (for Windows and Linux users) type git remote -v to list the current configured remote repo for your fork.
  2. git remote add upstream to specify new remote upstream repository that will be synced with the fork. You can type git remote -v to verify the new upstream.

If there are changes made in the original repository, you can sync the fork to keep it updated with upstream repository.

  1. In the terminal, change the current working directory to your local project
  2. Type git fetch upstream to fetch the commits from the upstream repository
  3. git checkout master to checkout your fork's local master branch.
  4. git merge upstream/master to sync your local master branch with upstream/master. Note: Your local changes will be retained and your fork's master branch will be in sync with the upstream repository.

Configure the app

The app can be run as-is, but it's recommended you do some configuration to set up OAuth to be relevant to your users. At minimum, the app should not be deployed without these changes:

  1. Register an ArcGIS Portal Application.
  2. Configure Data Collection project to reference that application.
  3. License the app to remove the Developer Mode watermark and for deployment.

1. Register an application

For OAuth configuration, create a new Application in your ArcGIS Portal to obtain a Client ID and configure a Redirect URL. The Client ID configures the ArcGIS Runtime to show your users, during the login process, that the application was built by you and can be trusted. The Redirect URL configures the OAuth process to then return to your app once authentication is complete.

  1. Log in to with either your ArcGIS Organizational Account or an ArcGIS Developer Account.
  2. Register a new Application. Register ArcGIS Application
  3. In the Authentication tab, note the Client ID and add a Redirect URL, e.g. data-collection://auth. We will use this URL in the Configuring the project section below. Configure ArcGIS Application

2. Configure the project

  1. Open the solution in Visual Studio and browse to the file named Configuration.xml located in the Properties directory of the DataCollection.Shared project.
  2. (Optionally) configure the WebmapURL to match your organization's webmap.
  3. Configure the OAuth Redirect URL.
    • Set the RedirectURL property to match the Redirect URL you have set up when you registered your application (see section above).
  4. Configure the Client ID.
    • Set the ClientID property with the Client ID generated when you registered your application (see section above).
