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

January 19, 2015 07:19 by author

Peter

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>

ASP.NET 5 Hosting France - HostForLIFE.eu :: Develop a Captcha Image Generator in ASP.NET

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.
UseCaptcha.aspx
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Create your own captcha image generator in ASP.NET using C#.NET/VB.NET</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
                <table>
                    <tr>
                        <td style="height: 50px; width: 100px;">
                            <asp:Image ID="imgCaptcha" runat="server" />
                        </td>
                        <td valign="middle">
                            <asp:Button ID="btnRefresh" runat="server" Text="Refresh" OnClick="btnRefresh_Click" />
                        </td>
                    </tr>
                </table>
            </ContentTemplate>
        </asp:UpdatePanel>
        Enter Captcha:
        <asp:TextBox ID="txtCaptcha" runat="server"></asp:TextBox><br />
        <asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" />
    </div>
    </form>
</body>
</html>

UseCaptcha.aspx.cs
using System.Text;
using System.Drawing.Imaging;
public partial class UseCaptcha : System.Web.UI.Page
{
   protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            FillCaptcha();
        }
    }
    void FillCaptcha()
    {
try
Random random = new Random();
string combination = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
StringBuilder captcha = new StringBuilder();
for (int i = 0; i < 6; i++)
captcha.Append(combination[random.Next(combination.Length)]);
Session["captcha"] = captcha.ToString();
imgCaptcha.ImageUrl = "GenerateCaptcha.aspx";
}
catch
{
throw;
}
}
protected void btnRefresh_Click(object sender, EventArgs e)
{
FillCaptcha();
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
if (Session["captcha"].ToString() != txtCaptcha.Text)
Response.Write("Enter Valid Captcha Code");
FillCaptcha();
}
}

And this is the result from the code:

The update also addresses three other cross-site scripting vulnerabilities, a cross-side request forgery flaw, a denial-of-service bug related to password checks, server-side request forgery issues, and what WordPress called “an extremely unlikely hash collision” that could lead to account compromise. WordPress said it also invalidates links in a password reset email if the user remembers our password and logs in and changes our email address.

WordPress 4.0.1 addresses an additional eight security issues, including three other XSS vulnerabilities that can be exploited by a contributor or an author, a cross-site request forgery (CSRF) that can be leveraged to trick a user into changing his/her password, and a denial-of-service (DoS) bug.

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">
    protected void Button1_Click(object sender, System.EventArgs e) {
        Label1.Text = "Your Country: " +
            TextBox1.Text.ToString() +
            "<br />Region: " +
            TextBox2.Text.ToString() +
            "<br />City: " +
            TextBox3.Text.ToString();
    }
