ControlDesigner.GetEditableDesignerRegionContent Method

Returns the content for an editable region of the design-time view of the associated control.

Namespace:  System.Web.UI.Design
Assembly:  System.Design (in System.Design.dll)

public virtual string GetEditableDesignerRegionContent(
	EditableDesignerRegion region
)

Parameters

region
Type: System.Web.UI.Design.EditableDesignerRegion

The EditableDesignerRegion object to get content for.

Return Value

Type: System.String
The persisted content for the region, if the control designer supports editable regions; otherwise, an empty string ("").

The default implementation of the GetEditableDesignerRegionContent method returns an empty string ("").

Classes deriving from the ControlDesigner class can support region-based editing on the design surface and override the GetEditableDesignerRegionContent method to return 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 creates the HTML markup for region and its contents.

// Get the content string for the selected region. Called by the designer host? 
public override string GetEditableDesignerRegionContent(EditableDesignerRegion region) 
{
    // Get a reference to the designer host
    IDesignerHost host = (IDesignerHost)Component.Site.GetService(typeof(IDesignerHost));
    if (host != null)
    {
        ITemplate template = myControl.View1;
        if (region.Name == "Content1")
            template = myControl.View2;

        // Persist the template in the design host 
        if (template != null)
            return ControlPersister.PersistTemplate(template, host);
    }

    return String.Empty;
}
