Radio button processing

Radio button processing

Radio button processing

I would like to add a Radio Button control within my asp.net Form. When the form is submitted, I would like the value of the Radio Control go to the "Code Behind page (Default.aspx.cs)". Using C#, I want the processing to occur there, and not within the page where the Form is (Default.aspx). Any suggestions? Bellow is a basic layout of the form with a working "Code behind page with existing Form controls"

Thanks in advance!


<%@ Page
Language = "C#"
AutoEventWireup = "false"
Inherits = "RadioButton.Default"
ValidateRequest = "false"
EnableSessionState = "false"

RE: Radio button processing

I am not understanding your question. Your radio button list is on Default.aspx. When you click the OK ,button the page posts back to itself. In the Page_Load or Button_Click event you can then get the value. So I am not understanding what you think will happen or what you want to happen

RE: Radio button processing

Ya, I know you can post back to the form page, no troubles there. My question was clearly stated, "Code Behind page". When I post the form, I wanted to display the value of the selected radio button. Anyway, I figured it out.

I added the following to the Button Click event in the "Code Behind Page", and got the result I wanted:

string stTest = Request.Form["RadioButtonList1"].ToString();

Works to perfection
