想取得一页中所有控件的类型,为什么取得不全呢?
代码如下,为什么只取得System.Web.UI.HtmlControls.HtmlForm与
System.Web.UI.LiteralControl这两个控件呢?TextBox与Button为什么没有被取得呢?我已用trace了,显示网页中不止这两个控件呀?大家帮帮忙呀,谢了.
<%@ Page Language= "VB " Debug= "true " Trace= "true "%>
<script language= "vb " runat= "server ">
Sub Page_Load(sender as Object, e as EventArgs)
Dim i as Integer
Response.Write(Controls.Count & " <BR> ")
For i = 0 To Controls.Count - 1
Response.Write(Controls(i).GetType.ToString() & " <BR> ")
Next i
End Sub
</script>
<Form runat= "server ">
<asp:TextBox id= "TextBox1 " runat= "server "/>
<asp:Button id= "Button1 " Text= "Button " runat= "server "/>
</Form>
[解决办法]
你应当继续遍历子控件。你目前只是循环了一层
