处理网站上的 Enter 键

Question

当我在登录表单中按 Enter 键时，网站顶部的搜索表单会运行。我正在尝试处理 enter 键，但我不断收到 missingmember 异常。

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)

        Dim getButton As New findbuttonControl
        Dim vButton As Object
        Dim getPassword As New findChildControl
        Dim vPassword As Object

        vButton = getButton.getGrandChildValue(Me.LoginView1.Controls, "Login1", "LoginButton")
        vPassword = getPassword.getGrandChildValue(Me.LoginView1.Controls, "Login1", "Password")

        vPassword.Attributes.Add("onkeydown", "if(event.which || event.keyCode){if ((event.which == 13) || (event.keyCode == 13)) {document.getElementById('" + vButton + "').click();return false;}} else {return true}; ")
End Sub

Answer 1

看看新的 ASP.Net 2.0 DefaultButton 属性。
