TreeListColumn Class

Represents a single column in the TreeList control.

Namespace:DevExpress.XtraTreeList.Columns
Assembly:DevExpress.XtraTreeList.v19.2.dll

Expanded Syntax

Expanded Remarks

The TreeListColumn class encapsulates a single column in the TreeList.

A Tree List column is a component. If a column is created at design time, it can be accessed in code by its name.

All columns can be accessed using the TreeList.Columns collection. This property provides an indexer (TreeListColumnCollection.Item) that enables you to access columns by their indexes (AbsoluteIndex) and field names (FieldName).

The Caption property allows you to set a Column Header to a custom string.

The OptionsColumn property defines a set of settings that control column focus, movement, data sorting and column size modifications. The appearance of column cells can be customized with the AppearanceCell property.

To change the text format of column cell values, use the Format property.

You can calculate summaries against a column using the RowFooterSummary and SummaryFooter properties.

To access a column value in a specific node, use the indexer provided by the Tree List node (TreeListNode.Item).

Expanded Example

The following example creates a TreeList (see TreeList) at runtime and shows how to perform basic customization tasks:

  • Bind the treelist to a data source
  • Specify the key fields that form a hierarchy
  • Access automatically created columns
  • Set a custom row height
  • Customize column captions (using HTML tags) and cell appearance settings
  • Create unbound columns and create Excel-style format conditions based on these column values
  • Assign an in-place editor (a spin editor) to columns
  • Sort data
  • Calculate total summaries
  • Filter nodes
  • Hide columns and calculate column "best" widths
  • Locate and expand nodes
  • Focus a specific cell
  • Specify DataAnnotation attributes at the data source level (the "p0" display format for the MarketShare field)
