ASP.NET 4.6 Hosting Portugal - HostForLIFE.eu :: How to Use Script to Disable Auto Fill TextBoxes in Some Browsers

clock September 26, 2015 12:59 by author Rebecca

Recent's browsers like Chrome, Firefox, Internet Explorer and Safari has functionality of auto complete values in TextBoxes. If you have enabled this features in browser, every time you start to enter value in TextBox you get a drop down of prefilled values in that TextBox. This feature of browser can be disabled by the programming for a specific web form like payment form and other confidential information form of a web application.

In chrome browser, you can enable auto-fill as shown below:

Step 1

Then you will have a below form for online payment of product by credit card or debit card then it is mandatory to stop auto complete functionality of browser so that browser doesn’t save the confidential information of a customer’s credit card or debit card.

 

Step 2


Then, you can turn off auto-fill for your complete form by setting autocomplete attribute value to off as shown below:

<form id="Form1" method="post" runat="server" autocomplete="off">

 .

 .

</form>

Step 3

You can also turn off auto-fill for a particular TextBox by setting autocomplete attribute value to off as shown below:

<asp:TextBox Runat="server" ID="txtConfidential" autocomplete="off"></asp:TextBox>

Step 4

And you can also do this from code behind also like as:

txtConfidential.Attributes.Add("autocomplete", "off");

After doing one of above code you will see that there is no auto-fill.

ASP.NET 4.6 Hosting UK - HostForLIFE.eu :: How to Use ASP.NET to Populate AJAX Control

clock September 17, 2015 12:03 by author Rebecca

The DynamicPopulate Control in the ASP.NET AJAX can call a page method and fill the resulting value in the target control on the page without a page refresh. The method call returns a form of  HTML string that is inserted as a child of the target element. The AJAX controls  work automatically. While it's possible to call (_doPostBack()) from JavaScript to trigger for a partial update. When  we use the ASP.NET DropDownList control, ASP.NET will verify that the items in the list are the same items the list contained when the page was rendered. Since we are adding items on the client side, a postback results in an ASP.NET validation error. This postback validation is designed to prevent users from editing your web pages and trying to submit invalid data. You can disable this validation but, for our purposes, it's simpler just to use a <select> tag.

Step 1

Open Visual Studio, Go to File->New->WebSite and Select ASP.NET Empty WebSite:

Step 2

  • Go to Solution Explorer and right-click.
  • Select Add->New Item.
  • Select WebForm.
  • Default.aspx page open

Step 3

Go to Default.aspx page and click on the [Design] option and drag control from Toolbox. Then, drag Panel control, Label, Button, Drop List control, ScriptManager control.

Step 4

The page contain a button with the ID PopList. The onclick attribute of this attribute calls the PopulateList() JavaScript function.

JavaScript Function

<title>my ajax application</title>
<style type="text/css">
        body
        {
            font-family: @BatangChe
            font-size: small;
            color: #555555;
        }
    </style>
    <script type="text/javascript">
        function PopulateList() {
            PageMethods.GetListData(1, OnPopulateList);
        }
        function OnPopulateList(list) {
            var dropList = document.getElementById('DropList');
            for (i = 1; i < 10; i++) {
                var option = document.createElement('OPTION');
                option.text = list[i].text;
                option.value = list[i].value;
                dropList.options.add(option);
            }
        }
    </script>

Step 5

Go to Default.aspx[Source] option and define the condition EnablePageMethod is "True" with ScriptManager and write a code:

<form id="form1" runat="server" style="background-color: #330D1E">
    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="True">
        </asp:ScriptManager>
        <p style="background-color: #2FC8D0">
        </p>
        <p style="background-color: #C0D1AF">
           How to populate control in ajax
        </p>
        <p style="background-color: #B8C9C9">
            <input id="PopList" type="button" value="Populate List"
                onclick="PopulateList();" style="background-color: #A5DCBD" />
        </p>
        <p style="background-color: #784847">
            <select id="DropList" name="DropListName"
                style="width: 200px; background-color: #B3CEC6;">
            </select>
        </p>
        <p style="background-color: #808080">
            <asp:Button ID="btnSubmit" runat="server" Text="Submit" />
        </p>
        <p style="background-color: #9A96E9">
            <asp:Label ID="lblSubmitValue" runat="server" BackColor="#FFFFCC"
                BorderWidth="15px"></asp:Label>
        </p>
    </div>
    </form>

Step 6

Now we create List Data Class. The data returns a list of objects for this class. The class consist two member Text, Value.

public class ListData
        {
            public string text { get; set; }
            public int value { get; set; }
        }

Step 7

Now we define the method for Client Side JavaScript and method return the data (List Data object):

public static IEnumerable<ListData> GetListData(int arg)
        {
            List<ListData> list = new List<ListData>();
            for (int i = 0; i < 100; i++)
                list.Add(new ListData()
                {
                    text = String.Format("List Item {0}", i),
                    value = i
                });
            return list;
        }

Step 8

The collection represents the raw values being posted to the page of List Data Items. Then these data items consist of the following namespace are use it.

using System.Collections.Generic;

Step 9

Now go to the Default.aspx.cs file; write code for the method to be called from client-side JavaScript:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class _Default : System.Web.UI.Page
{
        protected void Page_Load(object sender, EventArgs e)
        {
            if (Request.Form["DropListName"] != null)
                lblSubmitValue.Text = String.Format("Submitted Value: \"{0}\"",
                    Request.Form["DropListName"]);
        }
        public class ListData
        {
            public string text { get; set; }
            public int value { get; set; }
        }
        [System.Web.Services.WebMethod]
        [System.Web.Script.Services.ScriptMethod]
        public static IEnumerable<ListData> GetListData(int arg)
        {
            List<ListData> list = new List<ListData>();
            for (int i = 0; i < 100; i++)
                list.Add(new ListData()
                {
                    text = String.Format("List Item {0}", i),
                    value = i
                });
            return list;
        }
    }

Step 10

Now run the application pressing F5.

This page demonstrate how to dynamically populate a control using AJAX.

Step 11

Click on the populate list button to populate the dropdown list.

Step 12

Now click on the Submit button to submit the selected value back to the server.

Step 13

Now, you will change the dropdown list item and click on the submit button to again submit the selected value back to the server.

ASP.NET 4.6 Hosting - HostForLIFE.eu :: How to Use ASP.NET and C# to Show First & Last Day in a Month

clock September 7, 2015 09:17 by author Rebecca

In this post, I'm going to show you how calculate the first day and last day of a month for one of the project. The method that I'm using is very simple.

Here is the code:

DateTime today = DateTime.Now; //current date

DateTime firstDay = today.AddDays(-(today.Day - 1)); //first day

today = today.AddMonths(1);
DateTime lastDay = today.AddDays(-(today.Day)); //last day

The Explanation

The Calculation of First Day

DateTime firstDay = today.AddDays(-(today.Day - 1));

Here I'm using the AddDays method which can add given number of days to the current date. Using today.Day I'm extracting the current date day as integer value, which is 21 in my example. The tricky part here is that I'm adding with the AddDays method total of 21-1 = 20 and using the minus sign, it's getting 20 days back (instead of 20 days forward).

The Calculation of the Last Day

today = today.AddMonths(1);
DateTime lastDay = today.AddDays(-(today.Day)); //last day

With today = today.AddMonths(1) I'm adding one month plus to the current date.
Before adding, for example the today value was {21-07-2015 17:27:50} - after adding +1 month, the today value is {21-08-2015 17:27:50}.
Then, with the last line, the trick is very similar to the firstDayDate calculation, we only go in minus to the number of days got from the today.Day integer value. We do not add today.Day-1 here because if you do, you will get the first day of the next month (so you know one more thing now, how to get the first day of the next month).
The lastDay value will be 31-07-2015 17:27:50
