DataGridViewColumn.ReadOnly 属性

定义

命名空间:

System.Windows.Forms

程序集:

System.Windows.Forms.dll

获取或设置一个值，指示用户是否可以编辑列的单元格。

public:
 virtual property bool ReadOnly { bool get(); void set(bool value); };

public override bool ReadOnly { get; set; }

member this.ReadOnly : bool with get, set

Public Overrides Property ReadOnly As Boolean

属性值

Boolean

如果用户不能编辑列的单元格，则为 true；否则为 false。

例外

InvalidOperationException

对于绑定到只读数据源的列，此属性被设置为 false。

示例

下面的代码示例演示如何使用与 DataGridViewBand.ReadOnly 类的属性几乎完全相同 ReadOnly 的属性 DataGridViewColumn 。 此代码示例是类概述提供的较大示例的 DataGridViewBand 一部分。

// Make the entire DataGridView read only.
void Button8_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   System::Collections::IEnumerator^ myEnum = dataGridView->Columns->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      DataGridViewBand^ band = safe_cast<DataGridViewBand^>(myEnum->Current);
      band->ReadOnly = true;
   }
}

// Make the entire DataGridView read only.
private void Button8_Click(object sender, System.EventArgs e)
{
    foreach (DataGridViewBand band in dataGridView.Columns)
    {
        band.ReadOnly = true;
    }
}

' Make the entire DataGridView read only.
Private Sub Button8_Click(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles Button8.Click

    For Each band As DataGridViewBand In dataGridView.Columns
        band.ReadOnly = True
    Next
End Sub

注解

该 ReadOnly 属性会影响 DataGridViewCell.ReadOnly 列中每个单元格的属性。
