  • VSTO侧边面板CustomTaskPanes

    由于集团填报预算的Excel插件使用的是侧边自定义面板,感觉这种形式恰好比较适合手头的项目,所以把自己的插件改成侧边面板形式。

    Excel侧边面板可以直接添加“用户控件(windows窗体)”格式,类为:System.Windows.Forms.UserControl,也可以引入WPF的控件。

    我创建的窗体名称为:RightPanel

    默认的侧边面板是绑定工作簿的窗体的,不会自动切换,为了解决这个问题,创建了窗口句柄字典。最终实现效果如下

    具体代码如下

    
    private CustomTaskPane RightPane { get; set; } //侧边面板
    
    /// <summary>
    /// 侧边面板开关
    /// </summary>
    private void PanelOnOff_Click(object sender, RibbonControlEventArgs e)
    {
        ExcelApp = Globals.ThisAddIn.Application;
        int TempInt = Globals.ThisAddIn.Application.Hwnd;
        RefreshRightPane(TempInt);
    
        //设置面板可见性
        RightPane.Visible = PanelOnOff.Checked;
    }
    /// <summary>
    /// 重新绑定右侧面板
    /// </summary>
    /// <param name="HwndInt">当前窗体的句柄</param>
    private void RefreshRightPane(int HwndInt)
    {
        if (HwndPaneDic.ContainsKey(HwndInt))
        {
            RightPane = HwndPaneDic[HwndInt];
        }
        else
        {
            //创建控件
            UserControl rightPanel = new RightPanel();
            //添加控件
            RightPane = Globals.ThisAddIn.CustomTaskPanes.Add(rightPanel, "这里写窗体名称");
            //设置在右侧显示
            RightPane.DockPosition = Microsoft.Office.Core.MsoCTPDockPosition.msoCTPDockPositionRight;
            //禁止用户修改位置
            RightPane.DockPositionRestrict = Microsoft.Office.Core.MsoCTPDockPositionRestrict.msoCTPDockPositionRestrictNoChange;
            //事件
            RightPane.VisibleChanged += new EventHandler(CustomPane_VisibleChanged);
            //添加到字典
            HwndPaneDic.Add(HwndInt, RightPane);
        }
    
    }
    
    /// <summary>
    /// 侧边面板事件,用于保持按钮与面板状态一致
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    private void CustomPane_VisibleChanged(object sender, System.EventArgs e)
    {
        int TempInt = Globals.ThisAddIn.Application.Hwnd;
        PanelOnOff.Checked = RightPane.Visible;
        if (!PanelOnOff.Checked)
        {
            PanelOnOff.Label = "打开面板";
            PanelOnOff.ScreenTip = "点击打开侧边面板";
            ExcelApp.WindowActivate -= new Excel.AppEvents_WindowActivateEventHandler(CustomPane_WindowActivate);
            ExcelApp.WindowDeactivate -= new Excel.AppEvents_WindowDeactivateEventHandler(CustomPane_WindowDeactivate);
        }
        else
        {
            PanelOnOff.Label = "关闭面板";
            PanelOnOff.ScreenTip = "点击关闭侧边面板";
            ExcelApp.WindowActivate += new Excel.AppEvents_WindowActivateEventHandler(CustomPane_WindowActivate);
            ExcelApp.WindowDeactivate += new Excel.AppEvents_WindowDeactivateEventHandler(CustomPane_WindowDeactivate);
        }
    }
    
    /// <summary>
    /// 窗体激活事件
    /// </summary>
    /// <param name="WBK"></param>
    /// <param name="WD"></param>
    private void CustomPane_WindowActivate(Excel.Workbook WBK,Excel.Window WD)
    {
        ExcelApp.WindowActivate -= new Excel.AppEvents_WindowActivateEventHandler(CustomPane_WindowActivate);
        ExcelApp = Globals.ThisAddIn.Application;
        string WBKName = WBK.Name;
        
        int TempHwnd = WD.Hwnd;
        RefreshRightPane(TempHwnd);
        //设置面板可见性
        RightPane.Visible = true;
    
    }
    
    /// <summary>
    /// 窗体取消激活事件
    /// </summary>
    /// <param name="WBK"></param>
    /// <param name="WD"></param>
    private void CustomPane_WindowDeactivate(Excel.Workbook WBK,Excel.Window WD)
    {
        int TempHwnd = WD.Hwnd;
        if (HwndPaneDic.ContainsKey(TempHwnd))
        {
            HwndPaneDic[TempHwnd].Visible = false;
            ExcelApp.WindowActivate += new Excel.AppEvents_WindowActivateEventHandler(CustomPane_WindowActivate);
        }
    }
    
    //窗体句柄字典
    private Dictionary<int, CustomTaskPane> HwndPaneDic = new Dictionary<int, CustomTaskPane> { };
