Data Columns

  • 3 min to read

Data columns are used to display and edit data. The Bootstrap Card View supports bound and unbound data columns.

  • Bound data columns represent fields in Card View's data source. Their CardViewColumn.FieldName properties refer to valid fields in a data source.
  • Unbound columns are not bound to any field in a data source and should be populated manually. For more information, see Unbound Columns.

 

There are fifteen types of server data columns.

Behavior

Since different types of data columns present different types of data, they provide their own editors. For example, Boolean values are edited using a check box editor, while DateTime values are edited using a DateTime editor. To access and customize the column editor's settings, use the CardViewColumn.PropertiesEdit property.

Data columns provide a set of Boolean properties that enable you to specify which elements of a column's functionality (sorting, filtering, etc.) are available to end-users. These options can be accessed using the CardViewColumn.Settings property.

To make a column read-only, set its CardViewColumn.ReadOnly property to true.

Visibility

The column's visibility is specified by its WebColumnBase.Visible property. Its position among other visible columns is specified by its WebColumnBase.VisibleIndex property.
