ErrorListDockPanel Class
The Scripts Errors dock panel that displays the results of script validation in the End-User Report Designer.
Namespace: DevExpress.XtraReports.UserDesigner
Assembly: DevExpress.XtraReports.v25.2.Extensions.dll
NuGet Package: DevExpress.Win.Reporting
Declaration
Remarks
Click Validate in the error list to start script validation in the End-User Report Designer. When validation is complete, the ErrorListDockPanel displays the validation results.

An instance of the ErrorListDockPanel class is created when initializing the XRDesignDockManager component. To access the ErrorListDockPanel by specifying its type, name, or index in the XRDesignDockManager.DesignDockPanels collection, use the XRDesignDockManager.Item property with the DesignDockPanelType.ErrorList parameter.
Example
This example illustrates how to access and customize the Report Designer’s dock panels.
Important
Customization options described in this help topic are available to owners of DevExpress WinForms, DXperience, and Universal subscriptions (subscriptions that include DevExpress WinForms UI Controls). The DevExpress Reporting Subscription does not support UI customization in Report Viewer or End-User Report Designer. You can use ReportPrintTool and ReportDesignTool classes to display Print Preview and End-User Report Designer in their default configurations.
Refer to the following help topic for information on subscription options: Installation - Subscriptions that Include Reporting Components.
Note
All the Report Designer’s dock panels inherit their settings from the DesignDockPanel class which is a DockPanel class descendant.
For this reason, you need to reference the DevExpress.XtraBars.v25.2 library in your application to be able to access the Report Designer’s dock panel settings.
