Page_Load()
{

            RadioButton b = new Button();

            b.ID = "b1" //whatever 
            b.Text = "Option1"; //whatever
            b.AutoPostBack = true;
            b.CheckedChanged += new EventHandler(b_CheckedChanged); //handler

}



         void b_CheckedChanged(object sender, EventArgs e)
        {
            //whatever

        }

您可以像这样声明selectedindexchanged事件:

Hi,




you can declare selectedindexchanged event like this:

ddlFilter.SelectedIndexChanged += new EventHandler(ddl2_SelectedIndexChanged);
ddlFilter.AutoPostBack = true;
