Style.Font プロパティ

Web サーバー コントロールに関連付けられたフォント プロパティを取得します。

Public ReadOnly Property Font As FontInfo
[C#]
public FontInfo Font {get;}
[C++]
public: __property FontInfo* get_Font();
[JScript]
public function get Font() : FontInfo;

プロパティ値

Web サーバー コントロールのフォント プロパティを表す FontInfo

解説

Font プロパティを使用して、Web サーバー コントロールのフォント プロパティを指定します。このプロパティにはサブプロパティが含まれており、 Property-Subproperty の形式 (たとえば Font-Bold) の宣言によってアクセスしたり、プログラムで Property.Subproperty の形式 (たとえば Font.Bold) を使用してアクセスしたりできます。

1 つのサブプロパティを除くすべてのサブプロパティが、すべてのコントロールに対して、Microsoft Internet Explorer Version 4 より前のブラウザに表示されます。これらのサブプロパティは、 BoldItalicNameNamesStrikeout, Underline 、および Size ですが、Small や Smaller などの名前付きのフォント サイズだけは機能します。

メモ   これらのサブプロパティは、Microsoft Internet Explorer Version 4 より前のブラウザに表示されますが、表示される HTML は、Version 4 以降のブラウザに表示される HTML とは異なります。Version 4 より前では、スタイル属性ではなく、 <b><font> などの HTML 要素として表示されます。

すべてのコントロールに対して、下位レベルのブラウザに表示されない唯一のサブプロパティは、 Overline です。

使用例

 
<!-- 
This example demonstrates how to use a Style object to change the 
style properties of multiple controls at once.  Each time one of 
the Style property values changes, each control must call its 
ApplyStyle method. Note that not all the controls included support 
all the properties demonstrated. If a control does not support a 
particular property, the appearance of the control will not change 
when the property value is changed.
