}
}
试试用Page.RegisterStartupScript("","<script language=javascript>alert('"+Tb_DepartNo.Text +"$$$"+ Tb_DepartName.Text +"')</script>");
看看.点击 Btn_Save跟踪看看Tb_DepartNo.Text ,Tb_DepartName.Text是否有值
要解决这个问题,需要使用别的方法来实现,举例如下。
C#:
<%@ Page Language="C#" %>
<script runat="server">
protected void Button1_Click(object sender, EventArgs e)
{
Response.Write(TextBox1.Text);
}
protected void Page_Load(object sender, EventArgs e)
{
TextBox1.Attributes.Add("readonly", "true");
}

Response.Write(TextBox1.Text)

End Sub
