如何使用C＃隐藏字典键LookupEdit？

我创建了一个正常的winform并将LookUpEdit添加到我的表单中，并创建了一个包含string键和string值的字典。我使用BindingSource加载我的LookupEdit.Properties.Datasource。
当Lookupedit被加载，我想隐藏辞典键：如何使用C＃隐藏字典键LookupEdit？

private LookUpEdit lookup1; 

void InitializeComponent() 
{ 
    //... 
    this.lookup1 = new DevExpress.XtraEditors.LookUpEdit(); 
    this.lookup1.Anchor = ((System.Windows.Forms.AnchorStyles)(((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Left) 
         | System.Windows.Forms.AnchorStyles.Right))); 
    //this.cmbCards.DropDownStyle = System.Windows.Forms.ComboBoxStyle.DropDownList; 
    this.lookup1.Location = new System.Drawing.Point(400, 125); 
    this.lookup1.Name = "Test"; 
    this.lookup1.Properties.ShowHeader = false; 
    this.lookup1.Properties.ValueMember = "Test"; 
    this.lookup1.Size = new System.Drawing.Size(400, 85); 
    this.lookup1.TabIndex = 0; 
    this.lookup1.Tag = ""; 
    this.lookup1.Properties.BestFit(); 
    this.lookup1.Properties.ShowDropDown = DevExpress.XtraEditors.Controls.ShowDropDown.SingleClick; 
    this.lookup1.Properties.BestFit(); 
    this.lookup1.Properties.PopupWidth = 50; 
    this.lookup1.Properties.PopupSizeable = false; 
    //... 
} 

public partial class Form1 : Form 
{ 
    public Form1() 
    { 
     InitializeComponent(); 

     Dictionary<string, string> dic = new Dictionary<string, string>(); 
     dic.Add("Test", "1"); 
     dic.Add("Test2", "2"); 
     dic.Add("Test3", "3"); 
     dic.Add("Test4", "4"); 
     dic.Add("Test5", "5"); 
     dic.Add("Test6", "6"); 
     dic.Add("Test7", "7"); 
     dic.Add("Test8", "8"); 
     dic.Add("Test9", "9"); 
     dic.Add("Test10", "10"); 

     this.lookup1.Properties.DataSource = new BindingSource(dic, null); 
     this.lookup1.Properties.ShowLines = false; 
     this.lookup1.Properties.ShowPopupShadow = false; 
     this.lookup1.ItemIndex = 0; 
    } 
}

这说明如下：

Output 
Test 1 
Test2 2

我需要输出为 '1'
'测试' 必须是隐藏。

代码管理下面的事件背后

lookup1.Popup += new EventHandler(gridLookUpEdit1_Popup); 

protected void gridLookUpEdit1_Popup(object sender, EventArgs e) 
{ 
    this.lookup1.Properties.View.Columns[0].Visible = false; 
}

在LookUpEdit有这样为u提到的什么什么财产......但你可以这样做this.lookup1.Properties.Colu mns [0] .Visible = false; ，...这也失败了 –

@ user2046631你把这行代码放在你的代码中？ –

加载后字典我把这一行.... –

解决方案： 只需添加两列lookupEdit，然后分配datasource。之后，您将能够访问这些列。动态生成的列不会添加到lookupEdit.properties.Columns集合中。

参考LookUpEdit Class

使用此：

private void CreateLookupEdit() 
{ 
    ledMyControl = new LookUpEdit(); 
    ledMyControl.Properties.Columns.Add(new DevExpress.XtraEditors.Controls.LookUpColumnInfo("Key")); 
    ledMyControl.Properties.Columns.Add(new DevExpress.XtraEditors.Controls.LookUpColumnInfo("Value")); 

    this.Controls.Add(ledMyControl); 
    Dictionary<string, string> dic = new Dictionary<string, string>(); 
    dic.Add("Test", "1"); 
    dic.Add("Test2", "2"); 
    dic.Add("Test3", "3"); 
    dic.Add("Test4", "4"); 
    dic.Add("Test5", "5"); 
    dic.Add("Test6", "6"); 
    dic.Add("Test7", "7"); 
    dic.Add("Test8", "8"); 
    dic.Add("Test9", "9"); 
    dic.Add("Test10", "10"); 
    ledMyControl.Properties.DisplayMember = "Value"; 
    ledMyControl.Properties.ValueMember = "Key"; 
    ledMyControl.Properties.DataSource = dic.ToList(); 

    ledMyControl.Properties.Columns[0].Visible = false; 
}
