Parameters

region
Type: System.Web.UI.DesignEditableDesignerRegion

An editable design region contained within the control.

content
Type: SystemString

The content to assign for the editable design region.

Remarks

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.

Examples

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. Called by the designer host? 
Public Overrides Sub SetEditableDesignerRegionContent(ByVal region As EditableDesignerRegion, ByVal content As String)
    If IsNothing(content) Then 
        Return 
    End If 

    ' Get a reference to the designer host 
    Dim host As IDesignerHost = CType(Component.Site.GetService(GetType(IDesignerHost)), IDesignerHost)
    If Not IsNothing(host) Then 
        ' Create a template from the content string 
        Dim template As ITemplate = ControlParser.ParseTemplate(host, content)

        ' Determine which region should get the template 
        If region.Name.EndsWith("0") Then
            myControl.View1 = template
        ElseIf region.Name.EndsWith("1") Then
            myControl.View2 = template
        End If 

    End If 
End Sub
// 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)
        return;

    // 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);

        // 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;
    }
}
