DataError Property (Cell)

Returns the field data error as indicated by the underlying data item's IDataErrorInfo implementation.

Syntax

Visual Basic

'Declaration
 
Public ReadOnly Property DataError As Object

C#

public object DataError {get;}

Remarks

A data item can provide error information regarding the data item and individual fields of the data item by implementing IDataErrorInfo interface. If the data item associated with the data record implements IDataErrorInfo, this property returns the field error if any for this cell - basically the value returned by the IDataErrorInfo's Item[fieldName] indexer.

Note that the corresponding HasDataError property returns the value indicating whether there's a data error on this cell.

Also Note that by default the data presenter doesn't display the data error information. To have the data presenter display the data error information, set the FieldLayoutSettings' FieldLayoutSettings.SupportDataErrorInfo property.
