This example shows how to add custom function to the designer.

First, you need to add the StiNetCoreDesigner component to the view page. Also, you need to pass the StiNetCoreDesignerOptions object to the constructor. The minimum required options are two actions - GetReport and DesignerEvent: 
@using Stimulsoft.Report.Mvc;

...

@Html.StiNetCoreDesigner(new StiNetCoreDesignerOptions()
{
    Actions =
    {
        GetReport = "GetReport",
        DesignerEvent = "DesignerEvent"
    }
})

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

The OnPostGetReport() 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: 
static OnPostGetReport()
{
	var report = new StiReport();
	report.Load(StiNetCoreHelper.MapPath(this, "Reports/MyTwoSimpleLists.mrt"));
            
	return StiNetCoreDesigner.GetReportResult(this, report);
}

Now we need to add custom function using AddFunction() method: 
public static string MyFunc(string value)
{
	return value.ToUpper();
}
		
static IndexModel()
{
	var ParamNames = new string[1];
	var ParamTypes = new Type[1];
	var ParamDescriptions = new string[1];

	ParamNames[0] = "value";
	ParamDescriptions[0] = "Descriptions";
	ParamTypes[0] = typeof(string);

	// How to add my function
	StiFunctions.AddFunction(
	"MyCategory",
	"MyFunc",
	"MyFunc",
	"Description",
	typeof(IndexModel),
	typeof(string),
	"Return Description",
	ParamTypes,
	ParamNames,
	ParamDescriptions);
}
...

Finally, use DesignerEventResult() method to show results: 
...
public IActionResult OnGetDesignerEvent()
{
	return StiNetCoreDesigner.DesignerEventResult(this);
}

public IActionResult OnPostDesignerEvent()
{
	return StiNetCoreDesigner.DesignerEventResult(this);
}
