This example is outdated, you can check out the many other new examples in this category.This sample project demonstrates how to edit a report in the designer. First of all, create new StiReport():
private void buttonCreate_Click(object sender, EventArgs e)
{
	var report = new StiReport();
	report.Design();
}

...

Then, use Load method to attach report to the designer:
...

private void buttonEdit_Click(object sender, EventArgs e)
{
	var report = new StiReport();
	report.Load(@"Reports\SimpleList.mrt");
	report.Design();
}
