Remarks
The DataControlAllowReadUnexposedColumnsFromClientApiDefaultValue property controls client-side access to unexposed data source fields if the grid-like controls’ ASPxGridDataSecuritySettings.AllowReadUnexposedColumnsFromClientApi and/or the tree list’s TreeListSettingsDataSecurity.AllowReadUnexposedColumnsFromClientApi properties are set to Default.
Note
In version 18.1, we’ve changed this API behavior to improve data security of grid-like DevExpress web controls.
Breaking Change: The Specificity of accessing data field values from a client API of grid-like web controls topic illustrates details and describes how to revert to the previous behavior (degrading data security).
Example
The following example demonstrates how to prevent client-side API members of grid-like controls from accessing data source fields bound to hidden columns:
void Application_Start(object sender, EventArgs e) {
ASPxWebControl.BackwardCompatibility.DataControlAllowReadUnexposedColumnsFromClientApiDefaultValue = false;
}
