在分析ASP.NET页面的时候，在System.Web.UI.HtmlControls.HtmlControl类中，样式信息被填充到 CssStyleCollection类型的Style属性。这个属性本质上是一个字典，它把控件的样式暴露为每个样式属性键的按字符串索引的值集合。例如，你可以使用下面的代码设置和检索HtmlInputText服务器控件的width样式属性：
以下是引用片段：
＜script language="VB" runat="server" ＞
Sub Page_Load(Sender As Object, E As EventArgs)
MyText.Style("width") = "90px"
Response.Write(MyText.Style("width"))
End Sub
＜/script＞
＜input type="text" id="MyText" runat="server"/＞ |
下面的例子显示了如何编程使用Style集合属性来控制HTML服务器控件的样式：
以下是引用片段：
＜script language="VB" runat="server"＞
Sub Page_Load(Src As Object, E As EventArgs)
Message.InnerHtml &= "＜h5＞Accessing Styles...＜/h5＞"
Message.InnerHtml &= "The color of the span is: " &MySpan.Style("color") &"＜br＞"
Message.InnerHtml &= "The width of the textbox is: " &MyText.Style("width") &"＜p＞"
Message.InnerHtml &= "MySelect's style collection is: ＜br＞＜br＞"
Dim Keys As IEnumerator
Keys = MySelect.Style.Keys.GetEnumerator()
Do While (Keys.MoveNext())
Dim Key As String
Key = CStr(Keys.Current)
Message.InnerHtml &= "＜li＞ "
Message.InnerHtml &= Key &"=" &MySelect.Style(Key) &"＜br＞"
Loop
End Sub
Sub Submit_Click(Src As Object, E As EventArgs)
Message.InnerHtml &= "＜h5＞Modifying Styles...＜/h5＞"
MySpan.Style("color") = ColorSelect.Value
MyText.Style("width") = "600"
Message.InnerHtml &= "The color of the span is: " &MySpan.Style("color") &"＜br＞"
Message.InnerHtml &= "The width of the textbox is: " &MyText.Style("width")
End Sub
