Data Columns

  • 2 minutes to read
In This Article

Data columns are used to display and edit data. ASPxCardView supports both bound and unbound data columns.

  • Bound data columns represent fields in ASPxCardView‘s data source. A column’s CardViewColumn.FieldName property refers to its bound data source field.
  • Unbound columns are not bound to any field in a data source. These columns must be populated manually. See the following help topic for more information: Unbound Columns.

 

There are 15 types of server data columns.

#Behavior

Since different data column types display different data types, each column provides its own editor. For example, a check box editor is used to edit Boolean values, while a DateTime editor is used to edit DateTime values. 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. Use the CardViewColumn.Settings property to access these options.

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.
