as u can see the UserName textbox is inside the login control..so i cannot access its property..how do i find the control??

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.

Unfortunatelly, you didn’t format you code properly as I asked in a comment to your question. So I assume the login button is located in the same name container as the username text box and its name is btnLogin and you could set this control as a default control with HtmlForm.DefaultButton property, so:

You could use Page.SetFocus for this. It sets the browser focus to the specified control:

Page.SetFocus(txtName);

If you want to reach your UserName textbox, you could use just:

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;
    }
}

But note:

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).
