Save Selected Data of Radio Button List in ASP.Net

We make some true or false questions so the user will provide their answer and on a button click the answer will be saved to a database.

Initial Chamber

Step 1

Open your Visual Studio 2010 and create an empty website, provide a suitable name (RadioButtonList_demo).

Step 2

In Solution Explorer you get your empty website, add a web form and SQL Database as in the following.

For Web Form:

RadioButtonList_demo (your empty website) then right-click then select Add New Item -> Web Form. Name it RadioButtonList_demo.aspx.

For SQL Server database:

RadioButtonList_demo (your empty website) then right-click then select Add New Item -> SQL Server Database. (Add the database inside the App_Data_folder.)

Database Chamber

Step 3

In Server Explorer, click on your database (Database.mdf) then select Tables -> Add New Table. Make the table like this:

table design
This table is fore saving the data of the radio button list, I mean in this table we will get the user's answer of true and false questions.

Design Chamber

Step 4

Open your RadioButtonList_demo.aspx file from Solution Explorer and start the design of you're application.

Here is the code:

Finally open your RadioButtonList_demo.aspx.cs file to write the code, for making the list box like we assume.

Here is the code:
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Web;  
  5. using System.Web.UI;  
  6. using System.Web.UI.WebControls;  
  7. using System.Data;  
  8. using System.Data.SqlClient;  
  9.   
  10. public partial class _Default : System.Web.UI.Page  
  11. {  
  12.     protected void Page_Load(object sender, EventArgs e)  
  13.     {  
  14.   
  15.     }  
  16.     protected void Button1_Click(object sender, EventArgs e)  
  17.     {  
  18.         SqlConnection con = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Database.mdf;Integrated Security=True;User Instance=True");  
  19.         SqlCommand cmd = new SqlCommand("insert into tbl_data (ans,ans1,ans2) values (@ans,@ans1,@ans2)", con);  
  20.         cmd.Parameters.AddWithValue("ans", RadioButtonList1.SelectedItem.Text);  
  21.         cmd.Parameters.AddWithValue("ans1", RadioButtonList2.SelectedItem.Text);  
  22.         cmd.Parameters.AddWithValue("ans2", RadioButtonList3.SelectedItem.Text);  
  23.           
  24.         con.Open();  
  25.         int i = cmd.ExecuteNonQuery();  
  26.         con.Close();  
  27.   
  28.         if (i != 0)  
  29.         {  
  30.             lbmsg.Text = "Your Answer Submitted Succesfully";  
  31.             lbmsg.ForeColor = System.Drawing.Color.ForestGreen;  
  32.         }  
  33.         else  
  34.         {  
  35.            lbmsg.Text = "Some Problem Occured";  
  36.             lbmsg.ForeColor = System.Drawing.Color.Red;
