System.Web.UI.WebControls
程序集:
System.Web.dll

获取或设置单元格间的空间量。

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

属性值

Int32

单元格间的空间量（以像素为单位）。 默认值为 0。

属性

注解

CellSpacing使用 属性可以控制数据列表控件中相邻单元格之间的间距。 此间距同时以垂直和水平方式应用。 整个数据列表控件的单元格间距是统一的。 无法指定每行或每列之间的单独单元格间距。

注意

如果将此属性设置为大于 0 的值，并将属性设置为 GridLines 显示单元格边框的值，则相邻单元格的边框之间会显示一个间距。 在这种情况下， CellSpacing 属性控制间隙的大小。
