推荐答案

将文本框的AutoPostBack属性设置为true.
使用这个:

Hi,
Set the AutoPostBack property of textbox to true.
Use this:

protected void tb1_TextChanged(object sender, EventArgs e)
{
    TextBox tb1 = new TextBox(); 
    tb1.ID = "txt0";
    tb1.AutoPostBack = true;
    tb1.TextChanged += new EventHandler(tb1_TextChanged);
    t1.Visible = false;
}
//Make your textbox visible true in some event.
//you need to find your control first
protected someEvents(object sender, EventArgs e)
{
    TextBox t1=(TextBox)Page.FindControl("txt0")
    t1.Visible = true;
}

protected void tb1_TextChanged(object sender, EventArgs e)
{
    string tbvalue1 = string.Empty;
    string tbvalue2 = string.Empty;
}
