Use the DxReportDesignerCallbacks object properties to customize the Report Designer.

You must add the JavaScript functions that use the client-side API to customize components and specify the function names as handlers of the corresponding events.

Customize Menu, Toolbar, and Report Wizard

The following code removes a button from the left-side menu, moves the Save and New buttons to the toolbar, modifies the New button action, runs the Report Wizard on startup, and removes the Blank and Cross-Tab report types from the Wizard.

DesignerCustomization.razor

@page "/designercustomization"

<h1>End-User Report Designer - Customization</h1>
<ul>

    <li>New button creates a custom report instead of an empty one</li>
    <li>Wizard is run automatically on the startup</li>
    <li>Some report types are removed from the wizard</li>
</ul>
