Not applicable.



An editable design region contained within the control.


The content to assign for the editable design region.

Classes deriving from the ControlDesigner class can support region-based editing on the design surface and override the SetEditableDesignerRegionContent method to set the content for a specified region.

The following code example shows how to get a reference to the design host, and then use the reference to create a ControlParser object that turns content into an instance of the ITemplate interface and assigns the ITemplate instance to the appropriate view.

// Create a template from the content string and  
// put it in the selected view.
public override void SetEditableDesignerRegionContent(EditableDesignerRegion region, string content)
    if (content == null)

    // Get a reference to the designer host
    IDesignerHost host = (IDesignerHost)Component.Site.GetService(typeof(IDesignerHost));
    if (host != null)
        // Create a template from the content string
        ITemplate template = ControlParser.ParseTemplate(host, content);

        if (template != null)
            // Determine which region should get the template
            // Either 'Content0' or 'Content1'
            if (region.Name.EndsWith("0"))
                myControl.View1 = template;
            else if (region.Name.EndsWith("1"))
                myControl.View2 = template;
