Using the Displays List

List Interface

View Modes

• Grid View - Tabular display with sortable columns
• Card View - Visual preview thumbnails
• Toggle using buttons in top-right toolbar

Navigation Bar

Use the breadcrumb navigation in top-right to quickly switch between:

• List (current)
• Draw
• Layouts
• Client Settings

No need to use left-side tree navigation when working within Displays section.

Navigating to Draw Editor

Multiple methods to open a display for editing:

Solution Explorer Toggle

When Draw opens:

• Left panel auto-collapses for more drawing space
• Click ? (three bars) icon to expand/collapse Solution Explorer
• Useful when frequently switching between List and Draw

Creating Displays

From Display List

Creating New Displays

You can create a display in two sections of the software: Displays → List and Displays → Draw. These interfaces enable the creation and management of new displays.

1. Navigate to Displays → List
.
3. Click
the Image Removed button at the top to open the 'New Display' popup window.
4. Define the Name and Description of the display.
5. Define the Rendering Engine. This configuration item has three options: Portable (available for WPF and HTML5), WPF Only, and HTML5 Only.
6. Choose a Template for the display. If you do not select a template, a blank page will be created by default. Two types of templates must be highlighted:
   1. The Canvas option allows for manual positioning and sizing of elements.
   2. The Dashboard option automatically resizes and repositions elements, organizing the display into predefined regions. It provides a structured and uniform layout, ensuring that elements adapt to different screen sizes and resolutions without manual adjustments.
7. Finally, press the OK button to finish the display creation and close the popup window.

To create a display on Draw:

1. Navigate to Displays → Draw.
2. Click the Image Removed button at the top to open the 'New Display' popup window.
3. Follow the same procedure as for Displays → List.

For more information on display creation on Draw, see Drawing User Interface (Consolidate with Parent).

The Drawing the User Interface section of the Users covers the information about the drawing tools and CodeBehind editing. 

Displays Configuration Key Fields

1. + Add New button
2. Configure in dialog:
   • Name - Display identifier
   • Description - Purpose documentation
   • Rendering Engine - Target platform
   • Template - Starting layout from library
3. Click OK

Template Library

• Use predefined templates for consistency
• Canvas or Dashboard base types
• Industry-specific starting points

Special Pages

MainPage (ID 0)

• Cannot be deleted - Always exists
• Solution Center preview - Shows as project thumbnail
• Best practices:
  • Small apps: Use as main workspace
  • Large apps: Create separate "Main" workspace, use MainPage for preview only

Predefined Pages

These affect Rich Client development mode menus only.

Display Properties

Core Properties

Engine Types

System automatically promotes WPF to Portable when compatible during upgrades.

Navigation Flag

• Navigate checkbox - Used by DisplaySelection control
• Filters which displays appear in navigation lists
• Can be used in custom navigation logic

Build Status

What Gets Compiled

• CodeBehind scripts
• Expressions in graphical objects
• Dynamic bindings

Status Indicators

To fix errors:

1. Check BuildMessage column for details
2. Open in Draw → CodeBehind tab
3. Review expressions in visual elements

Security Settings

Organization

Categories

Group displays logically:

• Process Areas
• Equipment Types
• User Roles
• Functional Groups

Levels

Hierarchy indication:

• Top Level - Main screens
• Mid Level - Area displays
• Detail Level - Equipment views

Important Behaviors

Safe Renaming

• All references use internal ID, not name
• Rename displays anytime without breaking configuration
• Runtime continues working with new names

Development Tips

• Use WPF Rich Client for testing even when targeting web (faster)
• Development mode includes File/Security menus
• WebAssembly ensures consistent behavior across platforms

Lock Management

Lock States

• Unlocked - Available for edit
• Locked - Being edited by user
• LockOwner - Shows current editor

Managing Locks

csharp

// Check lock status
bool isLocked = Display.IsLocked;
string owner = Display.LockOwner;

// Force unlock (admin only)
Display.ForceUnlock();

Best Practices

1. Start with MainPage - Use for initial development
2. Use Templates - Consistent starting points
3. Name Meaningfully - Include area/function
4. Set Navigate Flag - Control navigation visibility
5. Monitor Build Status - Fix errors promptly
6. Use Portable Engine - Maximize compatibility
7. Configure Security - Set appropriate access

Troubleshooting

Build Errors:

• Check BuildMessage column for specifics
• Open in Draw editor
• Review CodeBehind tab
• Check expressions in elements

Display Not Opening:

• Verify RunSecurity permissions
• Check build status is Success
• Review client type compatibility
• Test with different user account

Navigation Issues:

• Use Preview column for double-click
• Check if display is locked
• Verify Navigate flag if using DisplaySelection
• Try pen icon or Draw shortcut

Metadata Tracking

All internal references use ID, making renaming safe at any time.

In this section...

Engine

The Engine field will specify if the display is intended for WPF, HTML5 or Portable.

When selecting WPF or HTML5, the design from Draw and CodeBehind will compile specifically for your selection. The Engine can be changed later on the Displays → List table.

The Portable option allows the automatic conversion between WPF and HTML5 technologies. The user does not need to create two different kinds of screens for Windows and Web Clients. Use the Portable option for the rendering engine to create the displays, and will automatically create them in both HTML5 and WPF. 

Mode

Mode is a read-only column. To modify it, go to Draw and change it in the Drawing Properties sidebar on the right, inside the Display Settings section.

Pages, Popups, and Dialogs are different display modes. They share some similarities, but each has a specific behavior. They are commonly used in application development to build intuitive and dynamic user interfaces.

Page

A Page is a display that always remains open or opens, replacing the previous display.

Popup

A Popup is a display that opens over the displays, remaining on top, but the User can still interact with the other pages (it's called a non-modal interface). A variation, available only for WPF, is the PopupWindow, which opens  a completely independent Window, with its own border, to show the display.

Dialog

A Dialog is a display that opens on top of all other displays, and stays open blocking the use of other displays until the User closes it (It is called a Modal interface).

PopupWindow

A PopupWindow opens a completely independent Window, with its own border, to show the display.

On Resize options

Under Display Settings, you can specify the settings for resizing an image or element to fit a designated display area.

StretchFill

This option stretches the image to fill the display area, potentially altering its aspect ratio. Distortion can occur if the display area's proportions differ from the image's original aspect ratio.

StretchUniform

This option will scale the image to fit the display area while maintaining its aspect ratio. If the aspect ratios don't match, the image will be scaled until it touches the edges of the container from within, potentially leaving some space in the display area.

Responsive

This option allows the image or element to adjust its size in response to the size of the display area. It's less clear without specific context, but typically, 'responsive' means that the element will scale sensibly to different screen sizes, often maintaining its aspect ratio without distortion.

NoAction

This option displays the image in its original size, regardless of the display area's size, which might lead to cropping or overflow if the image is larger than the display area.
