BaseDataList.CellPadding 屬性

定義

取得或設定儲存格內容和其框線之間的間距。

public:
 virtual property int CellPadding { int get(); void set(int value); };
[System.ComponentModel.Bindable(true)]
public virtual int CellPadding { get; set; }
public virtual int CellPadding { get; set; }
[<System.ComponentModel.Bindable(true)>]
member this.CellPadding : int with get, set
member this.CellPadding : int with get, set
Public Overridable Property CellPadding As Integer

屬性值

Int32

儲存格內容和其框線之間的間距數 (以像素為單位)。 預設值為 -1,表示這個屬性未設定。

備註

CellPadding使用 屬性來控制儲存格內容與儲存格框線之間的間距。 指定的填補量會新增至儲存格的所有四邊。

資料清單控制項相同資料行中的所有儲存格都會共用相同的儲存格寬度。 因此,如果一個儲存格的內容超過相同資料行中其他儲存格的內容,則填補量會套用至最寬的儲存格。 資料行中所有其他儲存格也會設定為這個儲存格寬度。

同樣地,相同資料列中的所有儲存格都會共用相同的高度。 填補量會套用至資料列中最高儲存格的高度。 資料列中所有其他儲存格都會設定為此儲存格高度。 無法指定個別儲存格大小。
