This example shows how to create a report designer and show it immediately. To create the report designer object you should use the StiDesigner class from the Stimulsoft.Designer namespace. After creation, the designer renders its own content automatically in the place in which the object was created:
<script type="text/javascript">
	// Create the report designer with default options and show it in this place
	var designer = new Stimulsoft.Designer.StiDesigner();
