Solution 2

Hi,

you can declare selectedindexchanged event like this:

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

check following code

protected void Page_Load(object sender, EventArgs e)
{
DropDownList ComboBox = new DropDownList();
ComboBox.ID = "ComboBox";
ComboBox.AutoPostBack = true;

ComboBox.Items.Add(new ListItem("Year: 2010", "2010"));
ComboBox.Items.Add(new ListItem("Year: 2011", "2011"));
ComboBox.Items.Add(new ListItem("Year: 2012", "2012"));
ComboBox.Items.Add(new ListItem("Year: 2013", "2013"));
ComboBox.Items.Add(new ListItem("Year: 2014", "2014"));

ComboBox.SelectedIndexChanged += new EventHandler(Dynamic_Method);

this.form1.Controls.Add(ComboBox);
}
protected void ddlFilter_SelectedIndexChanged(object sender, EventArgs e)
{
Response.Write(Request.Form["ComboBox"]);
}
private void Dynamic_Method(object sender, EventArgs e)
{
//Response.Write(((DropDownList)sender).SelectedIndex.ToString());
//Response.Write(Request.Form["ComboBox"]);
DropDownList ComboBox = (DropDownList)sender;
string sSTR = "";
sSTR = "</br>Selected Index: " + ComboBox.SelectedIndex.ToString();
sSTR += "</br>Selected Item: " + ComboBox.SelectedItem.Text.ToString();
sSTR += "</br>Selected Value: " + ComboBox.SelectedItem.Value.ToString();

Label lbl = new Label();
lbl.Text = sSTR;
this.form1.Controls.Add(lbl);
}

C#

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

        }
