add a property to your User Control:
<script language="C#" runat="server">
string m_sDataXMLFileName;
public string DataXMLFileName
{
get {return m_sDataXMLFileName;}
set {m_sDataXMLFileName= value;}
}
</script>
then in this page, you do
<script runat="server">
Sub Page_Load(sender As Object, e As EventArgs)
UserControl1.DataXMLFileName = "Data.xml"
End Sub
</script>
<script language="C#" runat="server">
string m_sDataXMLFileName;
public string DataXMLFileName
{
get {return m_sDataXMLFileName;}
set {m_sDataXMLFileName= value;}
}
</script>
then in this page, you do
<script runat="server">
Sub Page_Load(sender As Object, e As EventArgs)
UserControl1.DataXMLFileName = "Data.xml"
End Sub
</script>

在你的user control中，将DataXMLFileName设置为一个public的属性就可以了。
也可以在page_load中传值：
UserCotrol1.DataXMLFileName = "data.xml"
也可以在page_load中传值：
UserCotrol1.DataXMLFileName = "data.xml"

你应该在pagee_Load里
ReadOnly Property vara() As String
Get
Return "Data.xml"
End Get
End Property
ReadOnly Property vara() As String
Get
Return "Data.xml"
End Get
End Property
