System.Web.UI.Design.EditableDesignerRegion
The EditableDesignerRegion object to get content for.
Return Value
Type: System.StringThe 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 Overrides Function GetEditableDesignerRegionContent(ByVal region As EditableDesignerRegion) As String ' Get a reference to the designer host Dim host As IDesignerHost = CType(Component.Site.GetService(GetType(IDesignerHost)), IDesignerHost) If Not IsNothing(host) Then Dim template As ITemplate = myControl.View1 If region.Name = "Content1" Then template = myControl.View2 End If ' Persist the template in the design host If Not IsNothing(template) Then Return ControlPersister.PersistTemplate(template, host) End If End If Return String.Empty End Function
