ASPxGridColumnDataEventArgs.Value Property

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

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v18.2.dll

Declaration

C#

public object Value { get; set; }

VB.NET

Public Property Value As Object

Property Value

Type	Description
Object	An object that represents the currently processed cell’s value.

Remarks

If the ASPxGridColumnDataEventArgs.IsGetData property returns true (and consequently, the ASPxGridColumnDataEventArgs.IsSetData property returns false) the ASPxGridView.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 processed unbound column is identified by the ASPxGridViewColumnDataEventArgs.Column property. The ASPxGridColumnDataEventArgs.ListSourceRowIndex property can be used to identify the current row.

If the ASPxGridColumnDataEventArgs.IsGetData property returns false (and consequently, the ASPxGridColumnDataEventArgs.IsSetData property returns true) the ASPxGridView.CustomUnboundColumnData event handler should store the Value property’s value to the data source.
