Remarks

The DataControlPreventLoadClientValuesForReadOnlyColumns property controls access to client values of read-only columns on the server side if grid-like controls’ PreventLoadClientValuesForReadOnlyColumns and/or PreventLoadClientValuesForReadOnlyColumns properties are set to Default.

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).

Example

The following example illustrates how to allow controls to load their read-only column values from the client to the server side.

Global.asax:

C#

void Application_Start(object sender, EventArgs e) {
    ASPxWebControl.BackwardCompatibility.DataControlPreventLoadClientValuesForReadOnlyColumns = false;
}
