如何使DataGrid列可編輯

-1

我想讓DataGrid中的列可以編輯。我嘗試將readonly更改爲false，但這沒有幫助。如何使DataGrid列可編輯

所以任何人都可以告訴我任何其他方式，我可以嘗試或是這是不讓它是可編輯的。

感謝

我去DataDridView任務和特定的專欄中，我改變了只讀「假」。但是這沒有幫助。是的，它是一個WinForm。

的WinForms？的WebForms？ – trailmax

你應該更準確地描述你的問題。例如發佈一些代碼或告訴我們你到底在做什麼。 –

如果不雙擊單元格但單擊單元格會發生什麼？點擊哪個列？ – BlueM

好的，我發現你的問題。您最有可能使用的不是DataSource或使用ReadOnlyCollection作爲Datasource。然後DataGridView將不允許編輯。

我看到了與您相同的行爲，如果我只將行添加到數據網格。只要我使用BindingList作爲數據源，我可以編輯（單擊一次到單元格並開始鍵入）。您可能會考慮刪除雙擊處理程序，因爲這會干擾默認行爲。

這個工作對我來說：

public class Person 
{ 
    public string Name { get; set; } 
    public string EmpId { get; set; } 
} 

public MainForm() 
{ 
    InitializeComponent(); 

    // bind column to property of person 
    empName.DataPropertyName = "Name"; 
    empId.DataPropertyName = "EmpId"; 

    // set our bindinglist of persons as datasource 
    var bindingList = new BindingList<Person>(); 
    bindingList.Add(new Person(){ Name = "John", EmpId = "12345" }); 
    bindingList.Add(new Person(){ Name = "David", EmpId = "12346" }); 
    dgAttendanceLog.DataSource = bindingList; 
}

非常感謝@BlueM它的工作，在代碼中它只是只讀的，所以只是改變它，它工作正常。非常感謝您的支持。 – mark

在的WinForms，你可以DataGrid的編輯模式屬性設置爲EditOnEnter數據網格視圖的。也只讀屬性應該是假的。那麼你可以爲每個列設置ReadOnly。
