Data Columns

  • 3 minutes to read
In This Article

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.
