DataGridViewBand.ReadOnly 屬性

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

public virtual bool ReadOnly { get; set; }

member this.ReadOnly : bool with get, set

Public Overridable Property ReadOnly As Boolean

屬性值

如果使用者不能編輯群組列的儲存格，則為 true，否則為 false。 預設為 false。

例外狀況

範例

下列程式碼範例示範如何使用 ReadOnly 屬性來停用整個 DataGridView 的編輯。 此程式碼範例是提供給 類別之較大範例的 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

備註

屬性 ReadOnly 會影響 DataGridViewCell.ReadOnly 帶狀區中每個儲存格的 屬性。 例如，如果 ReadOnly 的 DataGridViewRow 屬性變更，則 DataGridViewCell.ReadOnly 資料列中所有儲存格的 屬性都會變更。
