DataGridView.AllowUserToResizeRows 屬性
定義
重要
部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
取得或設定值,指出使用者是否可以調整資料列的大小。
public:
property bool AllowUserToResizeRows { bool get(); void set(bool value); };
public bool AllowUserToResizeRows { get; set; }
member this.AllowUserToResizeRows : bool with get, set
Public Property AllowUserToResizeRows As Boolean
屬性值
如果可以調整所有資料列的大小,則為true
;否則為 false
。 預設為 true
。
範例
下列程式碼範例說明如何在主要用於顯示的控制項中使用 DataGridView 這個屬性。 在此範例中,控制項的視覺外觀會以數種方式自訂,而且控制項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;
dataGridView1.AllowUserToDeleteRows = false;
dataGridView1.AllowUserToOrderColumns = true;
dataGridView1.ReadOnly = true;
dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
dataGridView1.MultiSelect = false;
dataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.None;
dataGridView1.AllowUserToResizeColumns = false;
dataGridView1.ColumnHeadersHeightSizeMode =
DataGridViewColumnHeadersHeightSizeMode.DisableResizing;
dataGridView1.AllowUserToResizeRows = false;
dataGridView1.RowHeadersWidthSizeMode =
DataGridViewRowHeadersWidthSizeMode.DisableResizing;
// Set the selection background color for all the cells.
dataGridView1.DefaultCellStyle.SelectionBackColor = Color.White;
dataGridView1.DefaultCellStyle.SelectionForeColor = Color.Black;
// Set RowHeadersDefaultCellStyle.SelectionBackColor so that its default
// value won't override DataGridView.DefaultCellStyle.SelectionBackColor.
dataGridView1.RowHeadersDefaultCellStyle.SelectionBackColor = Color.Empty;
// Set the background color for all rows and for alternating rows.
// The value for alternating rows overrides the value for all rows.
dataGridView1.RowsDefaultCellStyle.BackColor = Color.LightGray;
dataGridView1.AlternatingRowsDefaultCellStyle.BackColor = Color.DarkGray;
// Set the row and column header styles.
dataGridView1.ColumnHeadersDefaultCellStyle.ForeColor = Color.White;
dataGridView1.ColumnHeadersDefaultCellStyle.BackColor = Color.Black;
dataGridView1.RowHeadersDefaultCellStyle.BackColor = Color.Black;
// Set the Format property on the "Last Prepared" column to cause
// 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
使用此屬性可防止使用者手動變更資料列高度。 例如,這非常有用,其中僅顯示控制項會載入一次資料,且資料列在該時間調整大小。
若要讓儲存格內容在重設資料列大小時換行到多行,儲存格的效果儲存格樣式必須具有 WrapMode 的屬性值 True 。
如需使用者調整大小的詳細資訊,請參閱dataGridView 控制項中的重設大小選項Windows Forms。
注意
控制項 DataGridView 不支援雙緩衝處理。 如果在 DoubleBuffered 衍生 DataGridView 控制項中設定為 true
,當使用者重設資料列、資料行或標頭的大小或重新排序資料行時,將不會收到視覺回饋。
