Data Grid - Cards - Overview

In Card View (CardView class), data source records are represented as cards arranged down and then across. The Layout View (LayoutView class) offers more layout modes and is significantly more advanced in terms of provided features and customization flexibility.

Common Information

Card View

Layout View

Cards

Cards in both Views display captions with embedded collapse\expand buttons for end-users to minimize and restore these cards. In cases where cards do not fit a current View height, end-users can scroll them. Neighboring cards are visually delimited by splitters that allow end-users to resize these cards (in Card View only).

Card View: Layout

The layout of cards in Card View depends on row and column counts, card size settings and card indents.

Rows and columns

Card size

  • CardView.CardWidth - specifies the card width (200 pixels by default). If the CardOptionsBehavior.AutoHorzWidth option is enabled, cards stretch horizontally to occupy the View's client area, but no more than the "MaximumCardColumns" setting allows them to.
  • Card height is determined automatically depending on the card content - cards stretch vertically until they reach the maximum available row height (the "MaximumCardRows" setting) or the current View's client area height.
  • If the CardOptionsView.ShowEmptyFields option is disabled, cards do not display empty values, which may cause cards to have different heights.

  • Cards can also have different heights when the CardOptionsBehavior.FieldAutoHeight setting is enabled. In this case, PictureEdit and MemoEdit in-place editors gain only as much height as their content requires.

Card Indent

  • Both vertical and horizontal distances between cards are controlled by the CardView.CardInterval property.

Card View: Scrolling

The Card View provides a horizontal scroll bar for the entire View (allows end-users to scroll through cards) and a vertical scroll bar for individual cards that do not fit vertically in the current View region. When scrolling horizontally, the minimal scroll step is one card.
