定义

命名空间:

System.Workflow.ComponentModel.Design

程序集:

获取与 WorkflowView 关联的垂直滚动条。

public:
 property System::Windows::Forms::VScrollBar ^ VScrollBar { System::Windows::Forms::VScrollBar ^ get(); };

public System.Windows.Forms.VScrollBar VScrollBar { get; }

member this.VScrollBar : System.Windows.Forms.VScrollBar

Public ReadOnly Property VScrollBar As VScrollBar

属性值

VScrollBar

一个用于调整水平滚动条的设置和可见性的 ScrollBar。

示例

下面的代码示例演示如何获取 WorkflowView 类的实例。 代码随后设置若干 WorkflowView 属性，包括 HScrollBar 和 VScrollBar，然后调用 FitToWorkflowSize 方法。

public void DisplayFullWorkflowView()
{
    IDesignerHost designerHost = designSurface.GetService(typeof(IDesignerHost)) as IDesignerHost;
    if (designerHost != null && designerHost.RootComponent != null)
    {
        WorkflowView workflowView = designerHost.RootComponent.Site.GetService(typeof(WorkflowView)) as WorkflowView;
        if (workflowView != null)
        {
            workflowView.Dock = DockStyle.Fill;
            workflowView.TabIndex = 1;
            workflowView.TabStop = true;
            workflowView.HScrollBar.TabStop = false;
            workflowView.VScrollBar.TabStop = false;
            workflowView.Focus();
            workflowView.FitToWorkflowSize();
        }
    }
}

Public Sub DisplayFullWorkflowView()
    Dim designerHost As IDesignerHost = CType(GetService(GetType(IDesignerHost)), IDesignerHost)
    If designerHost IsNot Nothing And designerHost.RootComponent IsNot Nothing Then
        Dim workflowView As WorkflowView = _
                    CType(designerHost.RootComponent.Site.GetService(GetType(WorkflowView)), WorkflowView)
        If workflowView IsNot Nothing Then
            workflowView.Dock = DockStyle.Fill
            workflowView.TabIndex = 1
            workflowView.TabStop = True
            workflowView.HScrollBar.TabStop = False
            workflowView.VScrollBar.TabStop = False
            workflowView.Focus()
            workflowView.FitToWorkflowSize()
        End If
    End If
End Sub

注解

使用 VScrollBar 可以获取 WorkflowView 上的垂直滚动条，可以使用它进行用户界面调整。
