Data Columns

  • 3 min to read

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

  • Bound data columns represent fields in the Bootstrap Grid View's data source. Their GridViewDataColumn.FieldName properties refer to valid fields in a data source.
  • Unbound columns are not bound to any field in a data source. These columns must be populated manually.

 

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 GridViewEditDataColumn.PropertiesEdit property.

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

To make a column read-only, set its GridViewDataColumn.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.
