动态创建的 Button, 怎么动态添加 OnClick 事件

[btbtd]

这里无效, 怎么才能引用 CheckLogin 方法?
//smtButton.OnClick=this.CheckLogin;

如下:
public void CheckLogin(Object s, EventArgs e)
{

}

public void Login(PlaceHolder LoginPh)
{
Literal Br=new Literal();
Br.Text="<br/>";

Literal ltUsername=new Literal();
ltUsername.Text="Username: ";

Literal ltPassword=new Literal();
ltPassword.Text="<br/>Password: ";

TextBox Username=new TextBox();
Username.ID="Username";

TextBox Password=new TextBox();
Password.TextMode=TextBoxMode.Password;
Password.ID="Password";

Button smtButton=new Button();
smtButton.Text="login now";
//smtButton.OnClick=this.CheckLogin;

LoginPh.Controls.Add(ltUsername);
LoginPh.Controls.Add(Username);
LoginPh.Controls.Add(ltPassword);
LoginPh.Controls.Add(Password);
LoginPh.Controls.Add(Br);
LoginPh.Controls.Add(smtButton);
}

[btbtd]

错误信息:

Compiler Error Message: CS0122: 'System.Web.UI.WebControls.Button.OnClick(System.EventArgs)' is inaccessible due to its protection level

Source Error:


Line 100: Button smtButton=new Button();
Line 101: smtButton.Text="login now";
Line 102: smtButton.OnClick=this.CheckLogin;
Line 103:
Line 104: LoginPh.Controls.Add(ltUsername);

[愚者只看星不看答案]

vb.net

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim btn As New Button
btn.ID = "btn1"
btn.Text = "btn1"
form1.Controls.Add(btn)
AddHandler btn.Click, AddressOf btn1_Click
End Sub

Public Sub btn1_click(ByVal sender As Object, ByVal e As EventArgs)
For Each ctl As Control In form1.Controls
If (ctl.GetType Is GetType(System.Web.UI.WebControls.Button)) Then
If CType(ctl, Button).ID = "btn1" Then
Response.Write(CType(ctl, Button).ID)
End If
End If
Next
End Sub

this.smtButton.Click += new System.EventHandler(this.CheckLogin);

[btbtd]

请问你这个问题怎么解决的？

smtButton.OnClick好像点不出来。
