Namespace: DevExpress.Web

Assembly: DevExpress.Web.v21.2.dll

NuGet Package: DevExpress.Web

Declaration

C#

[DefaultValue(DefaultBoolean.Default)]
public virtual DefaultBoolean PreventLoadClientValuesForReadOnlyColumns { get; set; }

VB.NET

<DefaultValue(DefaultBoolean.Default)>
Public Overridable Property PreventLoadClientValuesForReadOnlyColumns As DefaultBoolean

Property Value

Type	Default	Description
DefaultBoolean	Default	An enumeration value.

Available values:

Name	Description
True	true. DefaultBoolean.True has a constant value of 0, while the standard true value corresponds to a value of 1. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
False	false. DefaultBoolean.False has a constant value of 1, while the standard false value corresponds to a value of 0. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
Default	The default behavior determined by the control’s logic.

Remarks

Use the PreventLoadClientValuesForReadOnlyColumns property to specify whether to load read-only column values from the client to the server side in the ASPxGridView, ASPxCardView and ASPxVerticalGrid controls.

C#

ASPxGridView.SettingsDataSecurity.PreventLoadClientValuesForReadOnlyColumns = DefaultBoolean.True;
ASPxCardView.SettingsDataSecurity.PreventLoadClientValuesForReadOnlyColumns = DefaultBoolean.True;
ASPxVerticalGrid.SettingsDataSecurity.PreventLoadClientValuesForReadOnlyColumns = DefaultBoolean.True;

If the PreventLoadClientValuesForReadOnlyColumns property is set to Default, access to read-only values from the server side depends upon the DataControlPreventLoadClientValuesForReadOnlyColumns property setting.

Note

• In version 17.2, we’ve changed this API behavior to improve data security of grid-like DevExpress web controls.

  Breaking Change: The A read-only column’s editors reset client values to initial server values topic illustrates details and describes how to revert to the previous behavior (degrading data security).

• The PreventLoadClientValuesForReadOnlyColumns property has priority over the DataControlPreventLoadClientValuesForReadOnlyColumns property.
