推荐答案

我能够刷新页面，而不在文本框中清除值。我做到了，如下：
我创建了如下UC1.vb公共财产：
公共财产textbox_value（）作为字符串

I was able to refresh the page without clearing the value in textbox. I did it as below:I created a public property in the UC1.vb as below:Public Property textbox_value() As String

    Get
        If Session("textbox1") IsNot Nothing Then
            Return Session("textbox1").ToString()
        Else
            Return ""
        End If
    End Get
    Set(value As String)
        Session("textbox1") = value
    End Set
End Property

和用户控件的Page_Load事件我增加了code如下：
        如果随后的IsPostBack
            textbox_value = textbox1.Text
        elseif的不是那么的IsPostBack第一次页面加载或刷新页面时，
            textbox1.Text = textbox_value
         结束如果

And in the page_load event of the user control i added the code below: If IsPostBack Then textbox_value= textbox1.Text ElseIf Not IsPostBack Then ' First time the page is loaded or when the page is refreshed textbox1.Text = textbox_value End If

希望它帮助。
