CustomColumnDataEventArgs.Value Property

Gets or sets the value of the cell currently being processed.

Namespace: DevExpress.XtraGrid.Views.Base

Assembly: DevExpress.XtraGrid.v19.1.dll

Declaration

C#

public object Value { get; set; }

VB.NET

Public Property Value As Object

Property Value

Type	Description
Object	An object representing the value of the cell currently being processed.

Remarks

If the CustomColumnDataEventArgs.IsGetData property is set to true (and consequently the CustomColumnDataEventArgs.IsSetData property is set to false) a ColumnView.CustomUnboundColumnData event handler should provide data for the cell currently being processed. You need to obtain the data for this cell from a custom data source and assign it to the Value property.

The current unbound column is identified by the CustomColumnDataEventArgs.Column property. The CustomColumnDataEventArgs.ListSourceRowIndex property can be used to identify the current row.

If the CustomColumnDataEventArgs.IsGetData property is set to false (and consequently the CustomColumnDataEventArgs.IsSetData property is set to true) a ColumnView.CustomUnboundColumnData event handler should store the value of the Value property to the data source. In this case the event is called as a result of modifying the cell’s value via the grid.
