Properties

afterFinish Property

Occurs after the wizard’s onFinish method is called.

Declaration

"afterFinish": IAfterWizardFinishEventArgs

Property Value

Type	Description
IAfterWizardFinishEventArgs	The event’s arguments.

ASPX

<script type="text/javascript">
    function beforeFinish(s) {          
        if(!s.wizardModel.ReportTitle) {
            s.wizardModel.ReportTitle = "My Report"
            s.state.reportTitle = "My Report "
        }
    }
    function afterFinish(s) {
        s.wizardResult.name(s.state.reportTitle.replace(/ /g, ""))
        s.wizardResult.displayName(s.state.reportTitle)
    }
    function CustomizeWizard(s, e) {
        if(e.Type === "ReportWizard") {
            e.Wizard.events.addHandler("beforeFinish", beforeFinish)
            e.Wizard.events.addHandler("afterFinish", afterFinish)
        }
    }

The following example demonstrates how to hide the Select Data Source page from the Report Wizard and enable users to create SQL data sources only.

ASPX

<script type="text/javascript">
   function beforeInit(args) {
       args.state.dataSourceType = 1;
   }

   function afterInit(args) {
       // Remove the "Select Data Source" page's metadata from the factory.
       args.wizard.pageFactory.unregisterMetadata(DevExpress.Reporting.Designer.Wizard.FullscreenReportWizardPageId.SelectDataSourcePage);
       // Override the navigation logic to skip the "Select Data Source" page.
       var defaultGetNextPageId = args.wizard.iterator.getNextPageId;
       args.wizard.iterator.getNextPageId = function (pageId) {
           if (pageId === DevExpress.Reporting.Designer.Wizard.FullscreenReportWizardPageId.SelectReportTypePage) {
               return DevExpress.Reporting.Designer.Wizard.FullscreenReportWizardPageId.SpecifySqlDataSourceSettingsPage;
           } else {
               return defaultGetNextPageId.apply(this, [pageId]);
           }
       }
   }

   function CustomizeWizard(s, e) {
       if (e.Type === "ReportWizard") {
           e.Wizard.events.addHandler("beforeInitialize", beforeInit)
           e.Wizard.events.addHandler("afterInitialize", afterInit)
       }
   }

    function afterFinish(s) {
        s.wizardResult.name(s.state.reportTitle.replace(/ /g, ""))
        s.wizardResult.displayName(s.state.reportTitle)
