public sub Page_Load(sender as object,e as eventargs)
            dim CheckBox as checkbox
            checkbox = new CheckBox()
            checkbox.Checked = false
            checkbox.Text = "checkbox"
            div1.Controls.Add(checkbox)
End Sub
我用这个自动生成一个checkbox控件，我怎么在程序中调用它呢？比如点一个按钮  ，让它的 checked 变成 true，谢谢了！

像平时一样的调用方法就行了吧。

不行啊 ，出错，帮帮我吧

public partial class index : System.Web.UI.Page
{
    CheckBox checkbox = new CheckBox();
    protected void Page_Load(object sender, EventArgs e)
    {
            checkbox.Checked = false;
            checkbox.ID = "aaa";
            checkbox.Text = "checkbox";
            div1.Controls.Add(checkbox);
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        checkbox.Checked = true;
    }
}

flloor，我是用VB的，该怎么写呢？像你这样写出错

Partial Class _Default
    Inherits System.Web.UI.Page
    Dim checkbox As CheckBox
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles form1.Load
        checkbox = New CheckBox()
        checkbox.Checked = False
        checkbox.Text = "checkbox"
        checkbox.Visible = True
        div1.Controls.Add(checkbox)
    End Sub
    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        checkbox.Checked = True
    End Sub
End Class

<form id="form1" runat="server">
    <div id="div1" runat="server">
    </div>
    <asp:Button ID="Button1" runat="server" Text="Button" />
</form>
