Winforn中實(shí)現(xiàn)ZedGraph自定義添加右鍵菜單項(xiàng)(附源碼下載)：

在上面博客實(shí)現(xiàn)的自定義右鍵以及漢化右鍵的基礎(chǔ)上，怎樣實(shí)現(xiàn)將自帶的右鍵功能比如打印和頁面設(shè)置合并為一個(gè)選項(xiàng)打印，并將上兩個(gè)合并為其二級(jí)子菜單。

最終實(shí)現(xiàn)效果如下

實(shí)現(xiàn)

首先在循環(huán)所有的menuStrip.Items時(shí)候，通過item.Visible = false;將原來的打印與打印頁面設(shè)置的item禁用。

foreach (ToolStripMenuItem item in menuStrip.Items){switch (item.Name){case "copied_to_clip":item.Text = @"復(fù)制到剪貼板";break;case "copy":item.Text = @"復(fù)制";item.Click += item_Click;break;case "page_setup":item.Text = @"打印頁面設(shè)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(fù)默認(rèn)大小";break;case "show_val":item.Text = @"顯示節(jié)點(diǎn)數(shù)值";item.Visible = false;break;case "title_def":item.Text = @"標(biāo)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(kuò)展右鍵菜單時(shí)自定義二級(jí)子菜單效果，并在子菜單中執(zhí)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(shè)置");mnuPrintPageSet.Name = "printPageSet";mnuPrintPageSet.Text = "打印頁面設(shè)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(shí)現(xiàn)事件中

?private static void zgc_ContextMenuBuilder(ZedGraphControl control, ContextMenuStrip menuStrip, Point mousePt, ZedGraphControl.ContextMenuObjectState objState){#region 擴(kuò)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(shè)置");mnuPrintPageSet.Name = "printPageSet";mnuPrintPageSet.Text = "打印頁面設(shè)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(xiàng)foreach (ToolStripMenuItem item in menuStrip.Items){switch (item.Name){case "copied_to_clip":item.Text = @"復(fù)制到剪貼板";break;case "copy":item.Text = @"復(fù)制";item.Click += item_Click;break;case "page_setup":item.Text = @"打印頁面設(shè)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(fù)默認(rèn)大小";break;case "show_val":item.Text = @"顯示節(jié)點(diǎn)數(shù)值";item.Visible = false;break;case "title_def":item.Text = @"標(biāo)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}
