ASP.NET 5 Hosting Germany - HostForLIFE.eu :: Create DropDownList Validation with JQuery JavaScript In ASP.NET

January 19, 2015 07:19 by author

This article will explain you how Create DropDownList Validation with JQuery JavaScript in ASP.NET 5 where DropDown is either bind with SqlDataSource or listItems. Place one drop down and button on the page in design view and add JQuery javascript file in solution and add it's reference in head section of page. Then, Write following JQuery script in head section of page.

<head runat="server">
<title></title>
<script src="Scripts/jquery-1.7.2.min.js" type="text/javascript"></script>
<script type="text/javascript" language="javascript">
$(document).ready(function() {
$('#Button1').on('click', function(e) {
var selectedText = $('#DropDownList1
option:selected').text().toLowerCase();
if (selectedText == 'select')
{
alert('Please select any language.');
e.preventDefault();
}
else
alert('You selected ' + selectedText);
       })
})
</script>
</head>

HTML Code for Drop Down And Button
<asp:DropDownList ID="DropDownList1" runat="server">
<asp:ListItem>Select</asp:ListItem>
<asp:ListItem>C#</asp:ListItem>
<asp:ListItem>VB</asp:ListItem>
<asp:ListItem>Java</asp:ListItem>
<asp:ListItem>C</asp:ListItem>
</asp:DropDownList>
<asp:Button ID="Button1" runat="server" Text="Button" />

Now if DropDownList is obtaining populated from database by SqlDataSource then we'd like to line AppendDataBoundItems property of dropdown to true and add one list item with text choose at 0th index in Page_Load event.
<asp:DropDownList ID="DropDownList2" runat="server"
AppendDataBoundItems="True"
DataSourceID="SqlDataSource1"
DataTextField="ProductName"
DataValueField="ProductID">
</asp:DropDownList>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:TestDbConnectionString %>"
SelectCommand="SELECT [ProductID], [ProductName] FROM [Products]">
</asp:SqlDataSource>
<asp:Button ID="Button2" runat="server" Text="Button" />

Next step, write the following code in code behind.
protected void Page_Load(object sender, EventArgs e)
    {
        DropDownList2.Items.Add(new ListItem("select", "0"));
    }

Then write following JQuery code in head section of html source of page.
<script type="text/javascript" language="javascript">
$(document).ready(function() {
$('#Button2').on('click', function(e) {
var selectedValue = $('#DropDownList2').val();
if (selectedValue == 0)
{
alert('Please select any product.');
e.preventDefault();
}
else
alert('you selected product with ID ' + selectedValue);
})
})
</script>

If you wanna use the JavaScript code Instead of Jquery then write the following code:
<script type="text/javascript">
function Validation() {
var selectedValue =       document.getElementById('<%=DropDownList2.ClientID%>').value;
if (selectedValue == "0")
{
alert("Please Select Product");
}
else {
alert("You selected " + selectedValue);
}
}
</script>

Finally, Call the function bellow in OnClientClick Event of button:
<asp:Button ID="Button2" runat="server" Text="Button" OnClientClick="Validation>

December 19, 2014 05:38 by author

Peter

In this tutorial, I will explain you how to Develop a Captcha Image Generator in ASP.NET 5 with C# or VB.NET. CAPTCHA stands for "Completely Automated Public Turing test to tell Computers and Humans Apart". And here is the code that I use to generate take one .aspx page as GenerateCaptcha.aspx :

GenerateCaptcha.aspx.cs:
using System.IO;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.Drawing.Imaging;
public partial class GenerateCaptcha : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Response.Clear();
        int height = 40;
        int width = 110;
        Bitmap bmp = new Bitmap(width, height);
        RectangleF rectf = new RectangleF(12, 6, 0, 0);
        Graphics g = Graphics.FromImage(bmp);
        g.Clear(Color.White);
        g.SmoothingMode = SmoothingMode.AntiAlias;
        g.InterpolationMode = InterpolationMode.HighQualityBicubic;
        g.PixelOffsetMode = PixelOffsetMode.HighQuality;
        g.DrawString(Session["captcha"].ToString(), new Font("Cambria", 13, FontStyle.Bold), Brushes.Red, rectf);
        g.DrawRectangle(new Pen(Color.Green), 1, 1, width - 15, height -10);
        g.Flush();
        Response.ContentType = "image/jpeg";
        bmp.Save(Response.OutputStream, ImageFormat.Jpeg);
        g.Dispose();
        bmp.Dispose();
    }
}

Take .aspx where you want to use captcha.

ASP.NET 5 Hosting Italy - HostForLIFE.eu :: Using ValidationSummary Control in ASP.NET

December 15, 2014 06:01 by author

Peter

Today, I will show you how to ValidationSummary Control in ASP.NET 5. ValidationSummary control allow us to display summary of all validation errors. We can display validation errors summary inline of a web page or a message box or both by using ShowMessageBox and ShowSummary property value true or false.

ValidationSummary will display validation messages as bulleted list, 1 paragraph or only list based on DisplayMode. we can set a header text for validation summar. ASP.NET validationsummary control have many properties to design the error messages text as like fore color, back color, border color, border style, border width, theme, skin and after all CSS class.

This ValidationSummary, allow to summarize of all validation error messages from all validators in a single location. This code below will show you how can we display all validation error messages as summary using ValidationSummary control. In this example, I used three text box and make them required field using requiredfieldvalidator control. When user submit form without entering textboxes value, they got a validation error messages summary in one location as bulleted list.

And here is the example ValidationSummaryExample.aspx code:
<%@ Page Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">

        Label1.Text = "Your Country: " +
            TextBox1.Text.ToString() +
            "<br />Region: " +
            TextBox2.Text.ToString() +

ASP.NET 5 Hosting - HostForLIFE.eu :: Auto Resize Text Box in ASP.NET

December 5, 2014 06:53 by author

Peter

In this article, we want to talk about How to to develop a simple Example of text box control with ASP.NET 5. Once we enter data during this text box control we want to the length (re-size height and width) of text box. Text box is an ASP.NET web control, use for obtaining input by user as similar to the login web site we see username and password Textbox exactly in which we enter username and password. Inside the Toolbox we obtain a textbox only drag and drop it on ASP.NET web site and then it is automatically create our html code. We think about a text box and attempt to Auto re-size it once we enter value in text box.

And this is the example code that I used:
JavaScript function for resize ASP.NET control
And here is the Text Box auto resize function.

function resizemultilineTextBox(txt) {
            txt.style.height = "1px";
            txt.style.height = (1 + txt.scrollHeight) + "px";
        }
Asp.net web page code with Textbox:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Autoresizetextboxcontrol.aspx.cs" Inherits="Autoresizetextboxcontrol" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <title></title>
        <script>
        function resizemultilineTextBox(txt) {
            txt.style.height = "1px";
            txt.style.height = (1 + txt.scrollHeight) + "px";
        }
    </script>
    <style type="text/css">
        .style1
        {
            color: #990000;
            text-decoration: underline;
            font-family: Arial, Helvetica, sans-serif;
        }
    </style>
</head>
<body>
    <form id="form2" runat="server">
        <div align="center" style="height: 123px; background-color: #6699FF">
        <h1 class="style1">Auto Resize ASP.NET TextBox Control</h1>
            <table style="width: 494px">
                <tr>
                    <td>Enter Text Here: </td>
                    <td>
                        <asp:TextBox ID="txtDescription" runat="server"

onkeyup="resizemultilineTextBox(this)" TextMode="MultiLine" Width="212px">
</asp:TextBox>
                    </td>
                </tr>
            </table>

ASP.NET 5 Hosting - HostForLIFE.eu :: How to create “Remember Me” Login Page using checkbox with ASP.NET ?

December 1, 2014 06:12 by author

Peter

In this tutorial, I will tell you How to create “Remember Me” Login Page using checkbox with ASP.NET 5 and C#. Whenever you tick Remember Me checkbox it will maintain username and password for web site user using Cookies.

When user click login button that could stores the username and password inside the cookie. First thing you need to do is confirm that the Remember Me checkbox is checked or not, if it's checked then store the username and password inside the cookie to the 1 month and if not checked then set the expiration day to 1 day in else condition to destroy the cookie.

And here is the code that I used:

protected void Page_Load(object sender, EventArgs e)
{
      if (!Page.IsPostBack)
      {
           if (Request.Cookies["UserName"] != null)
                txtUserName.Text = Request.Cookies["UserName"].Value;
           if (Request.Cookies["Password"] != null)
                txtPassword.Text = Request.Cookies["Password"].Value;
           if (Request.Cookies["UserName"] != null && Request.Cookies["Password"] != null)
                chkRember.Checked = true;
      }
}
protected void btnLogin_Click(object sender, EventArgs e)
{
       string stringconnection = ConfigurationManager.ConnectionStrings["ConnString"].ConnectionString;
       MySqlConnection connection = new MySqlConnection(stringconnection);
      try
      {
           int flag = 0;
           if (chkRember.Checked == true)
           {
                Response.Cookies["UserName"].Value = txtUserName.Text;
                Response.Cookies["Password"].Value = txtPassword.Text;
                Response.Cookies["UserName"].Expires = DateTime.Now.AddMonths(1);
                Response.Cookies["Password"].Expires = DateTime.Now.AddMonths(1);
           }
           else
           {
                Response.Cookies["UserName"].Expires = DateTime.Now.AddMonths(-1);
                Response.Cookies["Password"].Expires = DateTime.Now.AddMonths(-1);
           }
           MySqlCommand com = new MySqlCommand("select * from tbl_user_details", connection);
           connection.Open();
           if (connection.State == ConnectionState.Open)
           {
                MySqlDataReader objSqlDataReader;
               objSqlDataReader = com.ExecuteReader();
                    while (objSqlDataReader.Read())
                     {
                     if (objSqlDataReader[2].ToString().Equals(txtUserName.Text) && objSqlDataReader[5].ToString().Equals(txtPassword.Text))
                     {
                          flag = 1;
                          Session["UserName"] = txtUserName.Text;
                          Session["UserType"] = objSqlDataReader[8].ToString();
                          Response.Redirect("ContactUs.aspx", false);
                     }
                     else
                     {
                          ClientScript.RegisterStartupScript(Page.GetType(), "validation", "<script language='javascript'>alert('Invalid Username and Password')</script>");
                    }
                }
           }
      }
      catch (Exception ex)
      {
           lblMsg.Text = ex.ToString();
      }
      finally
      {
           connection.Close();
      }
}
