TreeList.NodeCellStyle Event

Enables appearances to be assigned to individual cells.

Namespace:DevExpress.XtraTreeList
Assembly:DevExpress.XtraTreeList.v18.1.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type GetCustomNodeCellStyleEventArgs containing data related to this event.

The following GetCustomNodeCellStyleEventArgs properties provide information specific to this event.
Property Description
Appearance Gets the appearance settings used to paint the cell currently being processed.
Column Gets a column to which the cell processed by an event belongs.
Node Gets the current Tree List node.

Expanded Remarks

The NodeCellStyle event is raised for individual cells before they need to be repainted. The processed cell is identified by the event parameter's NodeEventArgs.Node and CellEventArgs.Column properties. To customize the appearance settings used to paint the cell use the GetCustomNodeCellStyleEventArgs.Appearance property.

If more complex cell painting needs to be performed, handle the CustomDrawNodeCell event.

For more information on appearances, see the Appearances document.

Note

The control's events designed to change the appearance or rendering of control elements must not be used to update cell values or to modify the control's layout. Any inappropriate operation which causes a layout update, may break the normal control behavior.

Expanded Example

The following sample code handles the NodeCellStyle event to modify the appearance of the "Budget" column's cells whose values are greater than 500,000.

The image below shows the result.
