RadioButtonList madness!

[V. Jenks]

I have a RadioButtonList and an ImageButton in my form.

In the ImageButton Click event handler I'm trying to
redirect to a new page, passing the value from the
RadioButtonList in a querystring.

Why do I get a null reference when trying to get the
value of the RadioButtonList ?

some code:

protected void AddToCartBttn_C lick(object
sender, System.Web.UI.I mageClickEventA rgs e)
{
if (Page.IsValid)
{
Response.Redire ct(
String.Format(
"/
{0}/store/cart.aspx?pid={ 1}&poid={2}",

this.WebRoot,

this.ProductID,

ProductOptionsL ist.SelectedIte m.Value //the
radiobuttonlist !
),
true
);
}
}
Thanks!

Hi V. Jenks,

Probably you can achieve this by using Server.Transfer method. You can find
a small example here at this url

Alternatively if you want to achieve this by passing the values of the
selected item using the query string try using Server.UrlEncod e as shown
below

Value1 and value2 are values for parameter 1 and parameter2.

Response.Redire ct( Server.UrlEncod e("pagetonaviga teto.aspx?param 1="+ value1
+"&param2="+val ue2));
