推荐答案

您可以使用此:

Hi,

You can use this:

if (!IsPostBack)
  {

  }

您可以在其中编写代码.

You can write the code inside this. It does not affect on postbacks.

< asp:textbox id ="TextBox1" runat ="server" readonly ="true" xmlns:asp =#unknown">

<asp:textbox id="TextBox1" runat="server" readonly="true" xmlns:asp="#unknown">

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        TextBox1.Text = "set Text on Page load Test";
    }

}

将文本框的EnableViewState 属性设置为true

默认情况下，此选项为true，请检查您是否在任何地方将其设置为false

Set EnableViewState property of textbox to true

This one is bydefault true check whether you have made it false anywhere
