我只是想知道如果我们不将 base.createchildcontrols() 放入代码中会发生什么。是否会在不调用 base.createchildcontrols() 的情况下创建复合控件?
[ToolboxData("<{0}:Login runat=server></{0}:Login>")]
public class Login : CompositeControl
{
private TextBox txtUsername = new TextBox();
private TextBox txtPassword = new TextBox();
private Button btnLogin = new Button();
protected override void CreateChildControls()
{
txtUsername.ID = "txtUsername";
txtPassword.ID = "txtPassword";
txtPassword.TextMode = TextBoxMode.Password;
btnLogin.ID = "btnLogin";
btnLogin.Text = "Login";
Controls.Add(txtUsername);
Controls.Add(txtPassword);
Controls.Add(btnLogin);
base.CreateChildControls();
}
}
