This example shows how to edit a report template in the designer. First, load scripts:

@using Stimulsoft.Base
@using Stimulsoft.Report
@using Stimulsoft.Report.Blazor
@using Stimulsoft.Report.Web

Then, add report designer:

<!--Report Designer-->
<StiBlazorDesigner Report="@Report" OnSaveReport="@OnSaveReport" />

After that, create empty report object and load report template:

@code
{
    //Report object to use in Designer
    private StiReport Report;

    protected override void OnInitialized()
    {
        base.OnInitialized();

        //Create empty report object
        this.Report = new StiReport();

        //Load report template
        this.Report.Load("Reports/TwoSimpleLists.mrt");
    }

...

Finally, create save method:

...

	private void OnSaveReport(StiSaveReportEventArgs args)
    {
        args.Report.Save("Reports/TwoSimpleLists.mrt");
    }
}

In the screenshot below you can see the result of the sample code:
