老哥们，求助！很急！关于后台动态添加自定义控件的问题！

有没有老哥在啊

bool flag = false;
protected void Page_Load(object sender, EventArgs e)
{
UnobtrusiveValidationMode = UnobtrusiveValidationMode.None;
}
protected void Button1_Click(object sender, EventArgs e)
{
set xx = (set)LoadControl("set.ascx");
if (flag == false)
{
center.Controls.Add(xx);
}
if (flag == true)
{
center.Controls.Remove(xx);
flag = false;
}
}
protected void Button2_Click(object sender, EventArgs e)
{
setpass pwd = (setpass)LoadControl("setpass.ascx");
if (flag == false)
{
center.Controls.Add(pwd);
}
if (flag == true)
{
center.Controls.Remove(pwd);
flag = false;
}
}
这是我添加控件的代码

试了下没什么问题, 你的用户控件里是不是还有别的逻辑?
