ControlDesigner.SetEditableDesignerRegionContent 方法

  • 參考

定義

命名空間:
System.Web.UI.Design
組件:
System.Design.dll

在設計階段指定控制項之可編輯區域的內容。

public:
 virtual void SetEditableDesignerRegionContent(System::Web::UI::Design::EditableDesignerRegion ^ region, System::String ^ content);
public virtual void SetEditableDesignerRegionContent (System.Web.UI.Design.EditableDesignerRegion region, string content);
abstract member SetEditableDesignerRegionContent : System.Web.UI.Design.EditableDesignerRegion * string -> unit
override this.SetEditableDesignerRegionContent : System.Web.UI.Design.EditableDesignerRegion * string -> unit
Public Overridable Sub SetEditableDesignerRegionContent (region As EditableDesignerRegion, content As String)

參數

region
EditableDesignerRegion

控制項中包含的可編輯設計區域。

content
String

要指派給可編輯設計區域的內容。

範例

下列程式碼範例示範如何取得設計主機的參考，然後使用 參考來建立 ControlParser 物件，該物件會變成 content 介面的 ITemplate 實例，並將實例指派 ITemplate 給適當的檢視。

// 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;
    }
}

' 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

備註

衍生自 類別的 ControlDesigner 類別可以支援設計介面上的區域型編輯，並覆寫 SetEditableDesignerRegionContent 方法來設定指定區域的內容。
