Migrate Report Viewer application

In our Bold Reports new assemblies are introduced for both client and server-side to resolve the compatibility problem between Essential Studio Report Viewer versions. It has changes in both Web API service and client-side scripts.

This section provides step-by-step instructions for migrating Report Viewer from Syncfusion Essential Studio release version to Bold Reports version of ASP.NET MVC Report Viewer application:

Client-side migration

In the Solution Explorer, right-click the References and remove the following assembly references:
- Syncfusion.EJ
- Syncfusion.EJ.MVC
Add the assembly from the Syncfusion NuGet package BoldReports.Mvc5. To add from NuGet, right-click the project or solution in the Solution Explorer tab, and choose Manage NuGet Packages. Search for BoldReports.Mvc5 NuGet package, and install in your application.

Refer to the NuGet Packages section to learn more details about installing and configuring Report Viewer NuGet packages.

Scripts and CSS references

Remove the following scripts and CSS references from the Report Viewer \Views\Shared\_Layout.cshtml page:
- ej.web.all.min.css
- ej.web.all.min.js
- ej.unobtrusive.min.js

The Report Viewer scripts and style sheets are added to the Scripts and Content folders in your application when installing the BoldReports.Mvc5 NuGet package. Add scripts as in the following code sample.

@Styles.Render("~/Content/bold-reports/material/bold.reports.all.min.css")
<!--Render the gauge item. Add these scripts only if your report contains the gauge report item.-->
@Scripts.Render("~/Scripts/bold-reports/common/ej2-base.min.js")
@Scripts.Render("~/Scripts/bold-reports/common/ej2-data.min.js")
@Scripts.Render("~/Scripts/bold-reports/common/ej2-pdf-export.min.js")
@Scripts.Render("~/Scripts/bold-reports/common/ej2-svg-base.min.js")
@Scripts.Render("~/Scripts/bold-reports/data-visualization/ej2-circulargauge.min.js")
@Scripts.Render("~/Scripts/bold-reports/data-visualization/ej2-lineargauge.min.js")
<!--Renders the map item. Add this script only if your report contains the map report item.-->
@Scripts.Render("~/Scripts/bold-reports/data-visualization/ej2-maps.min.js")
<!-- Report Viewer component script-->
@Scripts.Render("~/Scripts/bold-reports/common/bold.reports.common.min.js")
@Scripts.Render("~/Scripts/bold-reports/common/bold.reports.widgets.min.js")
<!--Renders the chart item. Add this script only if your report contains the chart report item.-->
@Scripts.Render("~/Scripts/bold-reports/data-visualization/ej.chart.min.js")
@Scripts.Render("~/Scripts/bold-reports/bold.report-viewer.min.js")

Open the the ~/Views/Shared/_Layout.cshtml page and replace the script manager tag at the end of <body> element from @(Html.EJ().ScriptManager()) to @(Html.Bold().ScriptManager()) as in the following code sample.
```
<body>
    ....
    ....
    
    @Html.Bold().ScriptManager()
</body>
```

Adding data visualization scripts

To render the report with data visualization components such as chart, gauge, and map items, add scripts of the visualization element. The following table shows the script reference that needs to be added in Report Viewer page for data visualization elements.

Visualization item	Script file
Gauge	ej2-base.min.js, ej2-data.min.js, ej2-pdf-export.min.js, ej2-svg-base.min.js, ej2-lineargauge.min.js and ej2-circulargauge.min.js
Map	ej2-maps.min.js
Chart	ej.chart.min.js

To render the chart report item, add chart control script ej.chart.min.js before the bold.report-viewer.min.js reference in the \Views\Shared\_Layout.cshtml page as demonstrated in the following code sample.

@Styles.Render("~/Content/bold-reports/material/bold.reports.all.min.css")
@Scripts.Render("~/Scripts/bold-reports/common/bold.reports.common.min.js")
@Scripts.Render("~/Scripts/bold-reports/common/bold.reports.widgets.min.js")

<!--Renders the chart item. Add this script, only if your report contains the chart report item.-->
@Scripts.Render("~/Scripts/bold-reports/data-visualization/ej.chart.min.js")

<!-- Report Viewer component script-->
@Scripts.Render("~/Scripts/bold-reports/bold.report-viewer.min.js")

The following code can be used to render the chart, gauge, and map report items in Report Viewer.

@Styles.Render("~/Content/bold-reports/material/bold.reports.all.min.css")

<!--Render the gauge item. Add these scripts only if your report contains the gauge report item.-->
@Scripts.Render("~/Scripts/bold-reports/common/ej2-base.min.js")
@Scripts.Render("~/Scripts/bold-reports/common/ej2-data.min.js")
@Scripts.Render("~/Scripts/bold-reports/common/ej2-pdf-export.min.js")
@Scripts.Render("~/Scripts/bold-reports/common/ej2-svg-base.min.js")
@Scripts.Render("~/Scripts/bold-reports/data-visualization/ej2-circulargauge.min.js")
@Scripts.Render("~/Scripts/bold-reports/data-visualization/ej2-lineargauge.min.js")

<!--Renders the map item. Add this script only if your report contains the map report item.-->
@Scripts.Render("~/Scripts/bold-reports/data-visualization/ej2-maps.min.js")

<!-- Report Viewer component script-->
@Scripts.Render("~/Scripts/bold-reports/common/bold.reports.common.min.js")
@Scripts.Render("~/Scripts/bold-reports/common/bold.reports.widgets.min.js")
<!-- Chart component script-->
@Scripts.Render("~/Scripts/bold-reports/data-visualization/ej.chart.min.js")
@Scripts.Render("~/Scripts/bold-reports/bold.report-viewer.min.js")

Control initialization

The component prefix has been changed from EJ() to SF().

Open the ~/Views/Web.config file and add the BoldReports.Mvc assembly reference to the <system.web.webPages.razor> element.

<configuration>
    ....
    ....
    <system.web.webPages.razor>
        ....
        ....
        <pages pageBaseType="System.Web.Mvc.WebViewPage">
            <namespaces>
                ....
                ....
                <add namespace="BoldReports.Mvc"/>
            </namespaces>
        </pages>
    </system.web.webPages.razor>
    ....
    ....
</configuration>

Set the value of UnobtrusiveJavaScriptEnabled to false in Root directory web.config file as demonstrated in the following code example.

<configuration>
<appSettings>
    ......
    ......
    <add key="UnobtrusiveJavaScriptEnabled" value="false" />
</appSettings>
......
......
</configuration>

Open the Report Viewer page in Index.cshtml page.
Replace the component tag Html.EJ().ReportViewer("viewer") with Html.Bold().ReportViewer("viewer").
```
<div style="min-height:600px">
    @(Html.Bold().ReportViewer("viewer"))
</div>
```

Server-side migration

In the Solution Explorer, right-click the References and remove the Syncfusion.EJ.ReportViewer assembly reference.
Add the assembly from the Bold Reports NuGet package BoldReports.Web. To add from NuGet, right-click the project or solution in the Solution Explorer tab, and choose Manage NuGet Packages. Search for BoldReports.Web NuGet package, and then install in your application.

Refer to the NuGet Packages section to learn more details about installing and configuring Report Viewer NuGet packages.

Web API Controller

The IReportController interface is moved to BoldReports.Web.ReportViewer. Open the Report Viewer Web API Controller file and remove the following using statement.
```
using Syncfusion.EJ.ReportViewer;
```
Add the following using statement.
```
using BoldReports.Web.ReportViewer;
```

Your application is successfully upgraded to the latest version of Report Viewer, and you can run the application with new assemblies.

Report export configuration

Now, the BoldReports.Web can export the reports with data visualization components only using web components. It is mandatory to configure the web scripts in Report Viewer Web API controller for exporting data visualization components such as chart, gauge, and map that are used in report definition. To configure the scripts in Web API, refer to the following steps:

Open the Report Viewer Web API controller.
Configure the following scripts and styles in OnInitReportOptions on Web API controller:
- jquery-1.10.2.min.js
- bold.reports.common.min.js
- bold.reports.widgets.min.js
- ej.chart.min.js - Exports the chart item. Add this script only if your report contains the chart report item.
- ej2-base.min.js, ej2-data.min.js, ej2-pdf-export.min.js, ej2-svg-base.min.js, ej2-lineargauge.min.js and ej2-circulargauge.min.js - Exports the gauge item. Add this script only if your report contains the gauge report item.
- ej2-maps.min.js - Exports the map item. Add this script only if your report contains the map report item.
- bold.report-viewer.min.js

Replace the following codes in Report Viewer Web API controller.

[NonAction]
public void OnInitReportOptions(ReportViewerOptions reportOption)
{
    var resourcesPath = System.Web.Hosting.HostingEnvironment.MapPath("~/Scripts");

    reportOption.ReportModel.ExportResources.Scripts = new List<string>
    {
        //Gauge component scripts
        resourcesPath + @"\bold-reports\common\ej2-base.min.js",
        resourcesPath + @"\bold-reports\common\ej2-data.min.js",
        resourcesPath + @"\bold-reports\common\ej2-pdf-export.min.js",
        resourcesPath + @"\bold-reports\common\ej2-svg-base.min.js",
        resourcesPath + @"\bold-reports\data-visualization\ej2-lineargauge.min.js",
        resourcesPath + @"\bold-reports\data-visualization\ej2-circulargauge.min.js",
        //Map component script
        resourcesPath + @"\bold-reports\data-visualization\ej2-maps.min.js",
        resourcesPath + @"\bold-reports\common\bold.reports.common.min.js",
        resourcesPath + @"\bold-reports\common\bold.reports.widgets.min.js",
        //Chart Component Script
        resourcesPath + @"\bold-reports\data-visualization\ej.chart.min.js",  
        //Report Viewer Script
        resourcesPath + @"\bold-reports\bold.report-viewer.min.js"
    };

    reportOption.ReportModel.ExportResources.DependentScripts = new List<string>
    {
        resourcesPath + @"\jquery-1.7.1.min.js"
    };
}

The data visulization components will not export without the above script configurations.
