場景
Winforn中實作ZedGraph自定義添加右鍵選單項(附原始碼下載)：
https://blog.csdn.net/BADAO_LIUMANG_QIZHI/article/details/100140716
在上面博客實作的自定義右鍵以及漢化右鍵的基礎上，怎樣實作將自帶的右鍵功能比如列印和頁面設定合并為一個選項列印，并將上兩個合并為其二級子選單，
最終實作效果如下

實作
首先在回圈所有的menuStrip.Items時候，通過item.Visible = false;將原來的列印與列印頁面設定的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 = @"列印頁面設定"; item.Visible = false; break; case "print": item.Text = @"列印"; 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; } }
然后在擴展右鍵選單時自定義二級子選單效果，并在子選單中執行ZedControl的自帶的右鍵事件，
ToolStripMenuItem mnuDirectPrint = new ToolStripMenuItem("直接列印"); mnuDirectPrint.Name = "directPrint"; mnuDirectPrint.Text = "直接列印"; mnuDirectPrint.Click += delegate(object sender, EventArgs e) { control.DoPrint(); }; ToolStripMenuItem mnuPrintPageSet = new ToolStripMenuItem("列印頁面設定"); mnuPrintPageSet.Name = "printPageSet"; mnuPrintPageSet.Text = "列印頁面設定"; mnuPrintPageSet.Click += delegate(object sender, EventArgs e) { control.DoPageSetup(); }; ToolStripMenuItem mnuPrint = new ToolStripMenuItem(); mnuPrint.Name = "mnuPrint"; mnuPrint.Text = "列印"; mnuPrint.DropDownItems.Add(mnuDirectPrint); mnuPrint.DropDownItems.Add(mnuPrintPageSet); menuStrip.Items.Add(mnuPrint);
完整示例代碼
首先右鍵選單事件重新訂閱
zgc.ContextMenuBuilder -= zgc_ContextMenuBuilder; //背景關系選單生成事件訂閱 zgc.ContextMenuBuilder += zgc_ContextMenuBuilder; //背景關系選單生成事件訂閱
然后在實作事件中
private static void zgc_ContextMenuBuilder(ZedGraphControl control, ContextMenuStrip menuStrip, Point mousePt, ZedGraphControl.ContextMenuObjectState objState) { #region 擴展背景關系選單 #region 列印 ToolStripMenuItem mnuDirectPrint = new ToolStripMenuItem("直接列印"); mnuDirectPrint.Name = "directPrint"; mnuDirectPrint.Text = "直接列印"; mnuDirectPrint.Click += delegate(object sender, EventArgs e) { control.DoPrint(); }; ToolStripMenuItem mnuPrintPageSet = new ToolStripMenuItem("列印頁面設定"); mnuPrintPageSet.Name = "printPageSet"; mnuPrintPageSet.Text = "列印頁面設定"; mnuPrintPageSet.Click += delegate(object sender, EventArgs e) { control.DoPageSetup(); }; ToolStripMenuItem mnuPrint = new ToolStripMenuItem(); mnuPrint.Name = "mnuPrint"; mnuPrint.Text = "列印"; 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 漢化背景關系選單中的選單項 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 = @"列印頁面設定"; item.Visible = false; break; case "print": item.Text = @"列印"; 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 }
