WinExplorer View

The WinExplorer View (the WinExplorerView) is a Data Grid View optimized for showing image-containing records. The View provides eight styles to represent data similarly to the way Windows Explorer does.

Expanded View Styles

The WinExplorer View features seven unique display modes or styles for its records. These styles specify what data each record shows and how it is presented on-screen. To select the currently active view style, utilize the WinExplorerViewOptionsView.Style property.

  • Tiles style: records display medium images with text captions, descriptions, and optional check boxes painted at the image's top-left corner. Check boxes are visible only when checked or hovered.
  • Small style: records display small images with text captions to the right and optional check boxes to the left. Records are arranged horizontally. Groups are placed one under another.
  • Medium style: records display medium images with text captions below and optional check boxes to the left.
  • Large style: records display large images with text captions below and optional check boxes to the left.
  • ExtraLarge style: records display extra-large images with text captions below and optional check boxes to the left.
  • Content style: records display medium images, bold text captions, and descriptions in a row. Records are arranged one under another and separated by horizontal lines. You can optionally display a check box to the left of the image.
  • List style: records display small images with text captions to the right and optional check boxes to the left. Records are arranged vertically, while groups are placed horizontally side-by-side. Groups display no collapse buttons.

Note that all styles have fixed designs that cannot be changed. If you want to customize data records' layout, try Tile View instead.

Expanded Column Set

A newly created WinExplorer View displays nothing at runtime even if the Data Grid is bound to a source. To have the View show data, select the data fields you want to show. To do so, expand the WinExplorerView.ColumnSet property in the VS Property Grid and assign automatically generated grid columns to the required properties.

Unlike regular Views that use columns or card fields to display any number of data source fields, the WinExplorer View's records are limited to a maximum of four data portions: an image, a short title, a detailed description and a check box.

Two additional properties in the ColumnSet group allow you to organize records in groups and/or render specific records disabled.

Expanded View and View Style Settings

The WinExplorerView.OptionsView property provides access to common View settings.

You can also specify unique settings for each individual View style. To do so, expand the WinExplorerView.OptionsViewStyles property and access properties exposed by the required sub-group.

Expanded Images

The table below describes all types of images the WinExplorer View supports.

Note that you do not need to assign image columns to all four properties - if there are no images of a size that the currently applied style requires, the View automatically scales images taken from other columns.

In View style settings, utilize the WinExplorerViewStyleOptions.ImageSize property to change the default image size for this View style.

Expanded Stub Glyphs

Instead of regular images, the WinExplorer View can display auto-generated images called stub glyphs. These are colored squares or circles with one or two initial letters of record title strings.

Expanded Asynchronous Image Load

Activating the Asynchronous Image Load mode allows you to do the following:

  • force the view to load images dynamically, on-demand, rather than all images at once;
  • retrieve images from the data source and manually transform them;
  • assign your own images from an external source;
  • display images with animation effects and show animated indicators for those images that are not yet ready.

Expanded Context Buttons

The WinExplorer records can display context buttons along their top and bottom sides. These buttons are by default visible only for hovered records.

To add context buttons, invoke the Collection Editor dialog by clicking the ellipsis button next to the WinExplorerView.ContextButtons property. The combo-box editor of this dialog allows you to add items of three types:

  • ContextButton - a regular push button that performs actions when clicked. With no glyph assigned, such buttons serve as labels;
  • CheckContextButton - check buttons that toggle their checked/unchecked states when clicked;
  • RatingContextButton - items that allow end-users to rate this item based on a default five-star grade.

Related API

  • TopPanelColor, BottomPanelColor - these properties, accessed through the WinExplorerView.ContextButtonOptions group specify colors for top and bottom panels that host context buttons. Use 4-number ARGB values to assign semi-transparent colors.

  • ContextItem.Visibility - specifies whether this button is always visible or only when the parent record is hovered (default behavior). If a button is constantly visible, its underlying button panel is shown as well. With this feature, you can clear the WinExplorerViewColumns.TextColumn property to replace default record titles with context buttons. The following image demonstrates a WinExplorer View record with a caption inside the record itself. A code sample for this task can be found later in this section.

The code below illustrates how to turn a regular context button into a label that shows a model name and a trademark for car records.
