CustomColumnDataEventArgs.IsSetData Property

Gets whether the current cell’s value should be stored in a custom data source.

Namespace: DevExpress.XtraGrid.Views.Base

Assembly: DevExpress.XtraGrid.v18.2.dll

Declaration

C#

public bool IsSetData { get; }

VB.NET

Public ReadOnly Property IsSetData As Boolean

Property Value

Type	Description
Boolean	true if the current cell’s value needs to be saved in a custom data source.

Remarks

If the IsSetData property is set to true (and consequently the CustomColumnDataEventArgs.IsGetData property is set to false) the CustomColumnDataEventArgs.Value parameter identifies the value which has been set for the current cell in the grid. This should be stored in your data source by the event handler.

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

If the IsSetData property returns false (and consequently the CustomColumnDataEventArgs.IsGetData property is set to true) the data for the currently processed cell should be supplied via the event handler. For this purpose retrieve a value from your data source based upon the current row and unbound column and assign it to the event’s CustomColumnDataEventArgs.Value parameter.
