i 是否有标识控制和建立用户控制,即我的网页......如果页数......怎么能做到,那么 cur子就应当放在标识控制的用户名框上?

<asp:LoginView ID="LoginView1" runat="server">
              <LoggedInTemplate>

              <AnonymousTemplate>

页: 1 用户Name 文本箱处于标识控制之内,因此无法获取其财产,我如何找到控制权?

Answer 1

EDIT: as you mentioned in comments, you want to set your login button to be clicked as a default button. For this you need to set this button as a default button.

令人不舒服的是,正如我在对你的提问发表评论时所问的那样,你采取了适当的形式。因此,我假定 log子位于与用户名箱相同的名称集装箱内,其名称为<代码>btn Carloin,你可将这一控制规定为默认控制。 HtmlForm.DefaultButton property, so:

您可使用Page.SetFocus。它把浏览器的重点放在特定的控制上:

Page.SetFocus(txtName);

如果你想要达到文本箱,你可以仅使用:

var login1 = LoginView1.FindControl("Login1") as Login;
if (login1 != null)
{
    var txtUserName = login1.FindControl("UserName");
    if (txtUserName != null)
    {
        Page.SetFocus(txtUserName);
    }

    var btnLogin = login1.FindControl("btnLogin");
    if (btnLogin != null) 
    {
         Page.Form.DefaultButton = btnLogin.UniqueID;
    }
}

但指出:

For the LoginView control, when being added onto a page, at a certain time, only one Template (anonymous or loggedIn ) is applied on the Control instance, so at that time, we can only retrieve the reference of those controls in the active template( can t access those in the non-active template).

Answer 2

英文版

textbox1.focus();

如果可能的话,则通过使用你必须掌握的身份证,才能在守则中控制。

Answer 3

The Default Focus property consider in this case:

// inside page_load, LoginUser is the Login control
Page.Form.DefaultFocus = LoginUser.FindControl("Username").ClientID;
