CustomTaskPane.DockPositionChanged 事件

当用户更改自定义任务窗格的停靠位置时，或者当代码更改 DockPosition 属性的值时发生。

命名空间：  Microsoft.Office.Tools
程序集：  Microsoft.Office.Tools.Common（在 Microsoft.Office.Tools.Common.dll 中）

语法

声明
Event DockPositionChanged As EventHandler

event EventHandler DockPositionChanged

示例

下面的代码示例演示 DockPositionChanged 事件的事件处理程序。此事件处理程序通过修改任务窗格上 FlowLayoutPanel 的 FlowDirection 属性来更改控件在任务窗格上的水平或垂直排列。此代码示例假定任务窗格包含一个名为 MyUserControl 的 UserControl，且 UserControl 包含一个名为 FlowPanel 的 FlowLayoutPanel。此示例摘自为 CustomTaskPane 提供的一个更大的示例。

Private Sub myCustomTaskPane_DockPositionChanged(ByVal sender As Object, _
    ByVal e As EventArgs) Handles myCustomTaskPane.DockPositionChanged

    Dim taskPane As Microsoft.Office.Tools.CustomTaskPane = _
        TryCast(sender, Microsoft.Office.Tools.CustomTaskPane)

    If taskPane IsNot Nothing Then

        ' Adjust sizes of user control and flow panel to fit current task pane size.
        Dim userControl As MyUserControl = TryCast(taskPane.Control, MyUserControl)
        Dim paneSize As System.Drawing.Size = _
            New System.Drawing.Size(taskPane.Width, taskPane.Height)
        userControl.Size = paneSize
        userControl.FlowPanel.Size = paneSize

        ' Adjust flow direction of controls on the task pane.
        If taskPane.DockPosition = _
            Office.MsoCTPDockPosition.msoCTPDockPositionTop Or _
            taskPane.DockPosition = _
            Office.MsoCTPDockPosition.msoCTPDockPositionBottom Then

            userControl.FlowPanel.FlowDirection = _
                System.Windows.Forms.FlowDirection.LeftToRight
        Else
            userControl.FlowPanel.FlowDirection = _
                System.Windows.Forms.FlowDirection.TopDown
        End If
    End If
End Sub

private void myCustomTaskPane_DockPositionChanged(object sender, EventArgs e)
{
    Microsoft.Office.Tools.CustomTaskPane taskPane =
        sender as Microsoft.Office.Tools.CustomTaskPane;

    if (taskPane != null)
    {
        // Adjust sizes of user control and flow panel to fit current task pane size.
        MyUserControl userControl = taskPane.Control as MyUserControl;
        System.Drawing.Size paneSize = new System.Drawing.Size(taskPane.Width, taskPane.Height);
        userControl.Size = paneSize;
        userControl.FlowPanel.Size = paneSize;

        // Adjust flow direction of controls on the task pane.
        if (taskPane.DockPosition == 
            Office.MsoCTPDockPosition.msoCTPDockPositionTop ||
            taskPane.DockPosition ==
            Office.MsoCTPDockPosition.msoCTPDockPositionBottom)
        {
            userControl.FlowPanel.FlowDirection =
                System.Windows.Forms.FlowDirection.LeftToRight;
        }
        else
        {
            userControl.FlowPanel.FlowDirection =
                System.Windows.Forms.FlowDirection.TopDown;
        }
    }
}
