In this article, I will show you step by step procedure, how to use a Masked Edit Extender
In ASP.NET using Visual Studio 2005 or Visual Studio 2008.
The use of Masked Edit Extender it that you are not required to type any number of character you have to just select from the up down button…it will change dynamically when you click the button,
To follow this code sample, you must use Visual Studio 2005 or Visual Studio 2008.
I have used <! – –> to comment HTML part of the code.
Note: Masked Edit Extender is a part of AjaxControlToolkit.
To attach right click on the toolbox under Ajax Extensions and select Choose Items - > Browse Button - > select the AjaxControlToolkit.dll. If you are using Visual Studio 2008, you may not need AJAX Toolkit but if you are using Visual Studio 2005, you will need to download it from http://www.msdn.com/ or http://www.asp.net/.
Step 1. Start -> All Programs -> Visual Studio 2005 or Visual Studio 2008
Step 2. Now go to File Menu -> New -> Web Site
Step 3.
Under Visual Studio Installed Template-> Choose ASP.NET WEB SITE -> Choose File System from the location combo box -> Set the path by the browse button - > Choose the language from the Language ComboBox (Visual C#, Visual Basic, J#)
Choose Visual C#
Step 4. Click on the OK Button.
This is the source code window and in this page you will se this code.
<%@ Page Language=”C#” AutoEventWireup=”true” CodeFile=”Default.aspx.cs” Inherits=”_Default” %>
<!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 runat=”server”>
<title>Type your webpage title here</title> <!– Here you can specify your page title in between title tag ->
</head>
<body>
<form id=”form1? runat=”server”>
<div>
<!– In between div tags you can manage your web controls like buttons, labels, picture Box, ImageMap etc –>
</div>
</form>
</body>
</html>
See here is a tab named Design in the bottom of this page.
Step 5. Click on this tab and you will see a blank web page where you can drag any control from the toolbox (which is in the left side of this window).
Step 6. Now drag controls under the AJAX Extensions.
First control you are going to drag and drop on the page is - Script Manager.
first add a tag on the top of your source code window:
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>
Under the form tag,
Don’t be frustrate on seeing this code please read carefully it’s very simple.
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<br />
Enter the details below in the textboxes and you will see how the masked control
Works
<br />
<div>
<asp:Label ID="Label1" runat="server" Text="Enter your name" ></asp:Label>
<asp:TextBox ID="TextBox1" runat="server" Width="150px"></asp:TextBox>
<br />
<br />
<asp:Label ID="Label2" runat="server" Text="Enter your roll number"></asp:Label>
<asp:TextBox ID="TextBox2" runat="server" Width="150px"></asp:TextBox>
<cc1:MaskedEditExtender ID="MaskedEditExtender1" runat="server" TargetControlID="TextBox2"
MaskType="Number" Mask="999" MessageValidatorTip="true" AcceptNegative="None"
InputDirection="RightToLeft" ErrorTooltipEnabled="true" >
</cc1:MaskedEditExtender>
<cc1:MaskedEditValidator ID="MaskedEditValidator1" runat="server"
ControlToValidate="TextBox2" ControlExtender="MaskedEditExtender1"
MinimumValue="1" MaximumValue="105" MinimumValueMessage="Please enter correct
roll number" MaximumValueMessage="Invalid roll number! The highest roll
number is 105" Display="Dynamic" IsValidEmpty="false"
InvalidValueMessage="The roll number does not exist" EmptyValueMessage="The roll number is not entered">
</cc1:MaskedEditValidator>
<br />
<br />
<asp:Label ID="Label3" runat="server" Text="Enter date of birth (mm/dd/yyyy)"></asp:Label>
<asp:TextBox ID="TextBox3" runat="server" Width="150px"></asp:TextBox>
<cc1:MaskedEditExtender ID="MaskedEditExtender2" runat="server" TargetControlID="TextBox3" MaskType="Date" Mask="99/99/9999" MessageValidatorTip="true" UserDateFormat="None" UserTimeFormat="None" InputDirection="RightToLeft" ErrorTooltipEnabled="true" >
</cc1:MaskedEditExtender>
<cc1:MaskedEditValidator ID="MaskedEditValidator2" runat="server" ControlToValidate="TextBox3" ControlExtender="MaskedEditExtender2" Display="Dynamic" IsValidEmpty="false" InvalidValueMessage="Invalid date!" EmptyValueMessage="The date is not entered">
</cc1:MaskedEditValidator>
<br />
Step 7. Now run your web site by Ctrl + F5

Step 8. When you run the Masked Edit Extender will seem like this...
![Masked TextBox.JPG]()
Now in the Masked text boxes you can’t enter characters or hexadecimal values you can only enter digits and here will be some restrictions… which the masked text box will follow …
Step 9. Close Browser
Step 10. Close Visual Studio…
