Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v14.2.dll

Declaration

C#

public event CustomColumnSortEventHandler CustomColumnGroup

VB.NET

Public Event CustomColumnGroup As CustomColumnSortEventHandler

Event Data

The CustomColumnGroup event's handler receives an argument of the CustomColumnSortEventArgs type. The following properties provide information specific to this event:

Property	Description
Column	Gets the column whose values are being compared.
Handled	Gets or sets whether a comparison operation is handled and no default processing is required.
ListSourceRowIndex1	Gets the index of the first of the two rows being compared in the data source.
ListSourceRowIndex2	Gets the index of the second of the two rows being compared in the data source.
Result	Gets or sets the result of a custom comparison.
SortOrder	Gets the sort order applied to the column.
Source	Gets the grid control that raised the event.
Value1	Gets the first value being compared.
Value2	Gets the second value being compared.

Remarks

If the built-in grouping modes don't suit your requirements, you can implement custom logic. To do this, set the ColumnBase.SortMode property to 'Custom', and handle the CustomColumnGroup event. To change the text displayed within group rows by default, handle the GridControl.CustomGroupDisplayText event.
