How to insert multiple Checkboxlist value into database in asp.net

 In this post I will explain how we can insert the multiple selected value of Checkbox list into your database.
And retrieve the values from database to bind to check box list,
In previous article, I have explained the Difference between WCF and Web API and WCF REST and Web Service and when to use Web API over others services. In this article, you will learn when to use Web API with MVC.

Description:
I have created table name StudentQualifications , ID as  primary key in table refer below table structure .

ID
int
C_QUALIFICATION
varchar(50)

Now go to Visual Studio and take new website. After that add a webform to application. Drag and drop
Checkboxlist control from Toolbox. and take values like this

<asp:CheckBoxList ID="chkeducation" runat="server">
      <asp:ListItem>PGDCA</asp:ListItem>      
      <asp:ListItem>M.SC.</asp:ListItem>
        <asp:ListItem>MBA</asp:ListItem>
        <asp:ListItem>B.TECH</asp:ListItem>
        <asp:ListItem>MCA</asp:ListItem>
        <asp:ListItem>B.SC.</asp:ListItem>
        <asp:ListItem>POST GRADUATION</asp:ListItem>
        </asp:CheckBoxList>
        
        <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Insert" />

Now go to .aspx.cs page. Add namespace.

using System.Data;
using System.Data.SqlClient;
using System.Configuration;

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["connection"].ToString());
protected void Page_Load(object sender, EventArgs e)
    {
        if (con.State == ConnectionState.Closed)
        {
            con.Open();
        }
    }
protected void Button1_Click(object sender, EventArgs e)
    {
        String str = "";
        for (int i = 0; i <= chkeducation.Items.Count - 1; i++)
        {
            if (chkeducation.Items[i].Selected)
            {
                if (str == "")
                {
                    str = chkeducation.Items[i].Text;
                }
                else
                {
                    str += "," + chkeducation.Items[i].Text;
                }
            }
        }
        con.Open();
        SqlCommand cmd = new SqlCommand("Insert into QUALIFICATION(C_QUALIFICATION) values('" + str + "')", con);
        cmd.ExecuteNonQuery();
        Clear();
    }
    public void Clear()
    {
        chkeducation.SelectedIndex = -1;
    }

 In VB.net refer bellow code 

Imports System.Data
Imports System.Data.SqlClient
Imports System.Configuration
Dim con As New SqlConnection(ConfigurationManager.ConnectionStrings("connection").ToString())
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
       If con.State = ConnectionState.Closed Then
            con.Open()
        End If
    End Sub
    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim str As [String] = ""
        For i As Integer = 0 To chkeducation.Items.Count - 1
            If chkeducation.Items(i).Selected Then
                If str = "" Then
                    str = chkeducation.Items(i).Text
                Else
                    str += "," + chkeducation.Items(i).Text
                End If
            End If
        Next
        Dim cmd As New SqlCommand("Insert into QUALIFICATION(C_QUALIFICATION) values('" & str & "')", con)
        cmd.ExecuteNonQuery()
        Clear()
        con.Close()
    End Sub
    Public Sub Clear()
        chkeducation.SelectedIndex = -1
    End Sub

Run the application you will get results ----happy coding

By using     SmtpClient . SendAsync Method (MailMessage, Object)    you need to do  System.Net.Mail has also added asynchronous support for sending email. To send asynchronously, you need need to Wire up a SendCompleted event Create the SendCompleted event Call SmtpClient.SendAsync smtpClient.send() will initiate the sending on the main/ui  thread and would block.  smtpClient.SendAsync() will pick a thread from the .NET Thread Pool and execute the method on that thread. So your main UI will not hang or block . Let's create a simple example to send mail. For sending mail asynchronously you need to create a event handler that will notify that mail success...

How to hide url parameters in asp.net

There are different ways to Hide the URL in asp.net , you can choose any one from bellow options . Previously I was Explained about the  Difference between Convert.tostring and .tostring() method Example  ,   Reasons to use Twitter Bootstrap , How to Register AJAX toolkit in web.config file in asp.net a) Using Post Method b) Using Of Session . c) URL Encoding & decoding process . d) Using Server.Transfer() instead of Response.Redirect() method (1)Use a form and POST the information. This might require additional code in source pages, but should not require logic changes in the target pages (merely change Request.QueryString to Request.Form). While POST is not impossible to muck with, it's certainly less appealing than playing with QueryString parameters. (2)Use session variables to carry information from page to page. This is likely a more substantial effort compared to (1), because you will need to take session variable checking into account...

I was looking for some way out either via any PHP or Microsoft.NET libraries, did some googling on that; but later on I just got an idea that google already has all code written for me.. when I have any email attachment in PDF or DOC or DOCX google does it for me ..! Even while searching I can see PDFs by converting them in HTML. So I just googled it up and found that Google already has this ability that we can use Google Docs Viewer without any Google Account Login . YES that's true no Google Account login is required. It's damn simple and easy. Just pass document path as attachment as parameter and we are done. Google Docs Viewer gives us ability to embed PDF, DOC/DOCX, PPT, TIFF:...
