Winforn中實現ZedGraph自定義添加右鍵菜單項(附源碼下載)：

https://blog.csdn.net/BADAO_LIUMANG_QIZHI/article/details/100140716

在上面博客實現的自定義右鍵以及漢化右鍵的基礎上，怎樣實現將自帶的右鍵功能比如打印和頁面設置合并為一個選項打印，并將上兩個合并為其二級子菜單。

最終實現效果如下

實現

首先在循環所有的menuStrip.Items時候，通過item.Visible = false;將原來的打印與打印頁面設置的item禁用。

foreach (ToolStripMenuItem item in menuStrip.Items){switch (item.Name){case "copied_to_clip":item.Text = @"復制到剪貼板";break;case "copy":item.Text = @"復制";item.Click += item_Click;break;case "page_setup":item.Text = @"打印頁面設置";item.Visible = false;break;case "print":item.Text = @"打印";item.Visible = false;break;case "save_as":item.Text = @"另存圖表...";break;case "set_default":item.Text = @"恢復默認大小";break;case "show_val":item.Text = @"顯示節點數值";item.Visible = false;break;case "title_def":item.Text = @"標題";break;case "undo_all":item.Text = @"還原所有縮放";item.Visible = false;break;case "unpan":item.Text = @"還原上一步縮放";item.Visible = false;break;case "unzoom":item.Text = @"還原縮放";item.Visible = false;break;case "x_title_def":item.Text = @"X 軸";break;case "y_title_def":item.Text = @"Y 軸";break;}}

然后在擴展右鍵菜單時自定義二級子菜單效果，并在子菜單中執行ZedControl的自帶的右鍵事件。

???? ToolStripMenuItem mnuDirectPrint = new ToolStripMenuItem("直接打印");mnuDirectPrint.Name = "directPrint";mnuDirectPrint.Text = "直接打印";mnuDirectPrint.Click += delegate(object sender, EventArgs e){control.DoPrint();};ToolStripMenuItem mnuPrintPageSet = new ToolStripMenuItem("打印頁面設置");mnuPrintPageSet.Name = "printPageSet";mnuPrintPageSet.Text = "打印頁面設置";mnuPrintPageSet.Click += delegate(object sender, EventArgs e){control.DoPageSetup();};ToolStripMenuItem mnuPrint = new ToolStripMenuItem();mnuPrint.Name = "mnuPrint";mnuPrint.Text = "打印";mnuPrint.DropDownItems.Add(mnuDirectPrint);mnuPrint.DropDownItems.Add(mnuPrintPageSet);menuStrip.Items.Add(mnuPrint);

完整示例代碼

首先右鍵菜單事件重新訂閱

??????????? zgc.ContextMenuBuilder -= zgc_ContextMenuBuilder;???? //上下文菜單生成事件訂閱zgc.ContextMenuBuilder += zgc_ContextMenuBuilder;???? //上下文菜單生成事件訂閱

然后在實現事件中

?private static void zgc_ContextMenuBuilder(ZedGraphControl control, ContextMenuStrip menuStrip, Point mousePt, ZedGraphControl.ContextMenuObjectState objState){#region 擴展上下文菜單#region 打印ToolStripMenuItem mnuDirectPrint = new ToolStripMenuItem("直接打印");mnuDirectPrint.Name = "directPrint";mnuDirectPrint.Text = "直接打印";mnuDirectPrint.Click += delegate(object sender, EventArgs e){control.DoPrint();};ToolStripMenuItem mnuPrintPageSet = new ToolStripMenuItem("打印頁面設置");mnuPrintPageSet.Name = "printPageSet";mnuPrintPageSet.Text = "打印頁面設置";mnuPrintPageSet.Click += delegate(object sender, EventArgs e){control.DoPageSetup();};ToolStripMenuItem mnuPrint = new ToolStripMenuItem();mnuPrint.Name = "mnuPrint";mnuPrint.Text = "打印";mnuPrint.DropDownItems.Add(mnuDirectPrint);mnuPrint.DropDownItems.Add(mnuPrintPageSet);menuStrip.Items.Add(mnuPrint);#endregion#region 縮放ToolStripMenuItem mnuReductLast = new ToolStripMenuItem("還原上一步縮放");mnuReductLast.Name = "mnuReductLast";mnuReductLast.Text = "還原上一步縮放";mnuReductLast.Click += delegate(object sender, EventArgs e){control.ZoomOut(control.GraphPane);};ToolStripMenuItem mnuReductAll = new ToolStripMenuItem("還原所有縮放");mnuReductAll.Name = "mnuReductAll";mnuReductAll.Text = "還原所有縮放";mnuReductAll.Click += delegate(object sender, EventArgs e){control.ZoomOutAll(control.GraphPane);};ToolStripMenuItem mnuReduct = new ToolStripMenuItem();mnuReduct.Name = "mnuReduct";mnuReduct.Text = "縮放";mnuReduct.DropDownItems.Add(mnuReductLast);mnuReduct.DropDownItems.Add(mnuReductAll);menuStrip.Items.Add(mnuReduct);#endregion#endregion#region 漢化上下文菜單中的菜單項foreach (ToolStripMenuItem item in menuStrip.Items){switch (item.Name){case "copied_to_clip":item.Text = @"復制到剪貼板";break;case "copy":item.Text = @"復制";item.Click += item_Click;break;case "page_setup":item.Text = @"打印頁面設置";item.Visible = false;break;case "print":item.Text = @"打印";item.Visible = false;break;case "save_as":item.Text = @"另存圖表...";break;case "set_default":item.Text = @"恢復默認大小";break;case "show_val":item.Text = @"顯示節點數值";item.Visible = false;break;case "title_def":item.Text = @"標題";break;case "undo_all":item.Text = @"還原所有縮放";item.Visible = false;break;case "unpan":item.Text = @"還原上一步縮放";item.Visible = false;break;case "unzoom":item.Text = @"還原縮放";item.Visible = false;break;case "x_title_def":item.Text = @"X 軸";break;case "y_title_def":item.Text = @"Y 軸";break;}}#endregion}
