如何读取文本框中的更改？ 如果按下按钮，页面加载时设置相同的值，而不是值在文本框中更改。

How can i read a change in the Textbox? it sets the same value when the page load if I press the button, and not the value that is changed in the text box.

Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load Dim txtvalue As string = "string inside textbox" Textbox1.Text = txtstring end sub Protected sub BTEdit_Click(sender As Object, e As EventArgs) Handles BTEdit.Click Dim Editetvalue as String Editetvalue = Textbox1.Text end sub

推荐答案

您可以使用实际的IsPostBack属性页面。 You can use the IsPostBack property of the actual page. Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load If Page.IsPostBack Then Dim txtvalue As string = "string inside textbox" Textbox1.Text = txtstring end if end sub
