Namespace: DevExpress.Web

Assembly: DevExpress.Web.v24.1.dll

NuGet Package: DevExpress.Web

Declaration

C#

[DefaultValue(true)]
public bool ConvertEmptyStringToNull { get; set; }

VB.NET

<DefaultValue(True)>
Public Property ConvertEmptyStringToNull As Boolean

Property Value

Type	Default	Description
Boolean	true	true if empty string values are converted to a null reference; otherwise, false.

Remarks

When an editor is used inplace within the ASPxGridView’s column, the editor binds to a value retrieved from the column’s associated data field. Use the ConvertEmptyStringToNull property to control whether empty string values should be converted to null values for the editor.

The ConvertEmptyStringToNull property is not in effect for the GridViewDataDateColumn object as a date column should not return an empty string to the server. If you need to pass an empty string to a data base, handle the RowUpdating and RowInserting events and convert required values from the e.NewValues array.
