This sample project demonstrates how you can add custom font to the resource.

First, you need to add the StiMvcDesigner component to the view page. Also, you need to pass the StiMvcDesignerOptions object to the constructor. The minimum required options are two actions - GetReport and DesignerEvent:

@using Stimulsoft.Report.Mvc;

...

@Html.Stimulsoft().StiMvcDesigner(new StiMvcDesignerOptions()
{
    Actions =
    {
        GetReport = "GetReport",
        DesignerEvent = "DesignerEvent"
    }
})

In the options above we define several actions, and we need to add it in the controller.

The GetReport() action loads the report template and returns answer to the client part of the designer using the GetReportResult() static method. In the parameters of this method, the report object should be passed:

...

public ActionResult GetReport()
{
	var report = new StiReport();

...

Next, load and add a font to the resources:

...

	// Loading and adding a font to resources
	var fileContent = System.IO.File.ReadAllBytes(Server.MapPath("~/Fonts/Roboto-Black.ttf"));
	var resource = new StiResource("Roboto-Black", "Roboto-Black", false, StiResourceType.FontTtf, fileContent, false);
	report.Dictionary.Resources.Add(resource);
			
...

After that, add a font from resources to the font collection:

...

	// Adding a font from resources to the font collection
	StiFontCollection.AddResourceFont(resource.Name, resource.Content, "ttf", resource.Alias);
			
...

Finally, create a text component:

...

	// Creating a text component
	var dataText = new StiText();
	dataText.ClientRectangle = new RectangleD(1, 1, 3, 2);
	dataText.Text = "Sample Text";
	dataText.Font = StiFontCollection.CreateFont("Roboto-Black", 12, FontStyle.Regular);
	dataText.Border.Side = StiBorderSides.All;

	report.Pages[0].Components.Add(dataText);

	return StiMvcDesigner.GetReportResult(report);
}
			
...
