DataGridViewRow.DefaultCellStyle 屬性

定義

命名空間:

System.Windows.Forms

組件:

System.Windows.Forms.dll

取得或設定資料列的預設樣式，可用來呈現資料列中的儲存格 (除非覆寫該樣式)。

public:
 virtual property System::Windows::Forms::DataGridViewCellStyle ^ DefaultCellStyle { System::Windows::Forms::DataGridViewCellStyle ^ get(); void set(System::Windows::Forms::DataGridViewCellStyle ^ value); };

[System.ComponentModel.Browsable(true)]
public override System.Windows.Forms.DataGridViewCellStyle DefaultCellStyle { get; set; }

[<System.ComponentModel.Browsable(true)>]
member this.DefaultCellStyle : System.Windows.Forms.DataGridViewCellStyle with get, set

Public Overrides Property DefaultCellStyle As DataGridViewCellStyle

屬性值

DataGridViewCellStyle

要套用為預設樣式的 DataGridViewCellStyle。

屬性

BrowsableAttribute

例外狀況

InvalidOperationException

在設定這個屬性時，資料列位於 DataGridView 控制項中而且是一個共用資料列。

範例

下列程式代碼範例說明如何在主要用於顯示的控件中使用 DataGridView 這個屬性。 在此範例中，控件的視覺外觀會以數種方式自定義，且控件會設定為有限的互動性。 此範例是類別概觀中較大範例的 DataGridViewCellStyle 一部分。

// Configures the appearance and behavior of a DataGridView control.
private void InitializeDataGridView()
{
    // Initialize basic DataGridView properties.
    dataGridView1.Dock = DockStyle.Fill;
    dataGridView1.BackgroundColor = Color.LightGray;
    dataGridView1.BorderStyle = BorderStyle.Fixed3D;

    // Set property values appropriate for read-only display and 
    // limited interactivity. 
    dataGridView1.AllowUserToAddRows = false;

    // the DateTime to be formatted as "Month, Year".
    dataGridView1.Columns["Last Prepared"].DefaultCellStyle.Format = "y";

    // Specify a larger font for the "Ratings" column. 
    using (Font font = new Font(
        dataGridView1.DefaultCellStyle.Font.FontFamily, 25, FontStyle.Bold))

        dataGridView1.Columns["Rating"].DefaultCellStyle.Font = font;
    }

    // Attach a handler to the CellFormatting event.
    dataGridView1.CellFormatting += new
        DataGridViewCellFormattingEventHandler(dataGridView1_CellFormatting);

備註

DataGridView控件會使用儲存格屬性所指示的樣式來顯示其儲存格InheritedStyle，這會繼承類型DataGridViewCellStyle之其他屬性的樣式。 對於此數據列中的儲存格，透過屬性指定的樣式會覆寫透過DataGridView.DefaultCellStyle、DataGridView.RowsDefaultCellStyleDataGridViewColumn.DefaultCellStyle 、 和 DataGridView.AlternatingRowsDefaultCellStyle 屬性所指定的DefaultCellStyle樣式，但由屬性DataGridViewCell.Style所指定的樣式覆寫。

如需詳細資訊，請參閱 DataGridView 控件中 Windows Forms 儲存格樣式。

取得此屬性時，如果尚未存取屬性， DataGridViewCellStyle 將會建立具有預設值的 。 這在取得許多數據列的這個屬性時，可能會造成效能影響。 盡可能使用單 DataGridViewCellStyle 一 來設定多個數據列的這個屬性。 如需詳細資訊，請參閱 縮放 Windows Form DataGridView 控制項的最佳做法。
