c＃查找contextSubMenu項目索引點擊

所以我有一個基本的佈局，我在這裏填充contextMenu的子菜單項與預設項目。我試圖找到所選子菜單項的'索引'。這有什麼方法？我找到了一種方法來查找主菜單項的索引，但找不到子菜單項。c＃查找contextSubMenu項目索引點擊

你需要索引本身？或者你只是用它來查找產品？ – 2014-09-02 18:18:04

用它從列表中查找產品。因此，contextMenu預設列表中的第三項將是變量存儲列表中的第三項。 – JokerMartini 2014-09-02 18:22:34

@DJKRAZE我在發佈這篇文章之前查看了你正在引用的帖子，並且我看到他正在使用'SubmenuItem_Click'，在試圖研究他的結果時我找不到任何信息。 – JokerMartini 2014-09-02 18:28:32

您可以執行以下操作。

private void contextMenuStrip1_Opening(object sender, CancelEventArgs e) 
    { 
     (contextMenuStrip1.Items[0] as ToolStripMenuItem).DropDownItems.Clear(); 
     (contextMenuStrip1.Items[0] as ToolStripMenuItem).DropDownItemClicked -= DropDownItemClicked; 
     (contextMenuStrip1.Items[0] as ToolStripMenuItem).DropDownItemClicked += DropDownItemClicked; 


     foreach (var p in productList) 
     { 
      var itemName = p.Name; 
      (contextMenuStrip1.Items[0] as ToolStripMenuItem).DropDownItems.Add(itemName, null, SelectedPreset); 
      } 
    } 

    private void DropDownItemClicked(object sender, ToolStripItemClickedEventArgs e) 
    { 
     var parent = (ToolStripMenuItem)sender; 

     int index = parent.DropDownItems.IndexOf(e.ClickedItem); 
     Debug.WriteLine(index); 
    }

但即使是更好地做到這一點：

private void contextMenuStrip1_Opening(object sender, CancelEventArgs e) 
    { 
     (contextMenuStrip1.Items[0] as ToolStripMenuItem).DropDownItems.Clear(); 

     foreach (var p in productList) 
     { 
      var itemName = p.Name; 
      var item = (contextMenuStrip1.Items[0] as ToolStripMenuItem).DropDownItems.Add(itemName, null, SelectedPreset); 
      item.Tag = p; 
     } 
    } 


    private void SelectedPreset(object sender, EventArgs e) 
    { 
     var menuItem = (ToolStripItem)sender; 
     Debug.WriteLine(((Product)menuItem.Tag).Name); 
    }

贏家！真棒。謝謝 – JokerMartini 2014-09-02 18:42:28

地址：

public class Product 
{ 
    // : 
    public override string ToString() { return Name; } 
}

然後在contextMenuStrip1_Opening存儲整個對象，而不僅僅是名字。

private void contextMenuStrip1_Opening(object sender, EventArgs e) 
    { 
     var ddi = (contextMenuStrip1.Items[0] as ToolStripMenuItem).DropDownItems; 
     ddi.Clear(); 

     foreach (var p in productList) 
     { 
      ddi.Add(p, null, SelectedPreset); 
     } 
    }

有沒有submenuItem點擊事件，可以趕上發件人或e.click索引？ – JokerMartini 2014-09-02 18:15:11
