This article shall describe the construction of a custom control used to display currency values. The control is intended for use in Win Forms application development. The purpose of control is to allow the user to enter numeric values which are subsequently converted to and displayed as currency as is indicated in figure 1 below. The user of the control may drop any number of the currency controls into a form to display numeric values as currency; the control itself is merely an extended textbox.

By placing the code necessary to support the functionality into the format of a custom control, the need for writing the code necessary to support the display of currency for each textbox used is eliminated. Getting Started. The solution contains two projects. The first project is provided to demonstrate use of the control in a Win Forms application.

The second project contains the actual custom control which is called "CurrencyTextBox". The Custom Control Project. The custom control's code contains all of the necessary methods used to restrict user input and to display the values into a textbox as a currency value. The control contains only the default imports as shown in the following:. Following the using statements and the namespace declaration, the class is configured to inherit from the standard textbox control.

By inheriting from the textbox control, all of the functionality of the control is included. After declaring the class, the next section of code is used to declare a private member variable which, through a public property, is used to store the current dollar value. Maintaining the dollar value as an internal variable is necessary to support edits to the underlying value after the value has been converted to a formatted string.

It further allows the user to perform calculations against this value when, for example, the contents of multiple controls are added together. InitializeComponent. OnPaint pe. The next section of code in the control is used to handle the keypress event. The purpose of the keypress event handler is to limit the user to keying in numbers and decimal points. The handler also allows the users to use the backspace button and other control characters when editing the contents of the currency text box.

This code also limits the user to entering in only a single decimal point.

IsDigit e. IsControl e. Contains ". After the keypress event handler, the next section of code is used to handle the "validated" event for the control.

This handler will attempt to convert the contents of the textbox to a properly formatted currency value. ToDecimal this. In the case of this control, the intent is to convert the value displayed in the textbox back to the actual underlying control value as it stored in control the actual decimal value. If the current dollar value property is zero, the application will clear the textbox so that the user does not end up with the cursor trailing the zero.

If the dollar value property does contain a value, the cursor is positioned at the end of that value. ToString. Clear. The next section of code after the click event handler is the code used to handle the text changed event for the control. In this instance, whenever the value in the control is changed, the dollar value property is updated to hold the latest value.

Text .In some applications we need to show the input text in a TextBox with some mask, like, for example, a currency mask to make it more easy to read and understand. In my case, I needed to put text, and additionally, the currency symbol, once the text was written. To do that, I decided to develop a control that inherits from the original TextBox control and implements some new members to allow the control to validate and show the input text with the currency mask we need.

The TextBox control is one of the basic and most used controls in WinForms applications that allows the user to input text to interact with the application. It has basics behaviors and members that allow us to use it instantly without having to add anything to the control. Based on the TextBox control, we are going to develop a TextBox that can mask our input text with currency format, including the currency symbol that we want. Inheritance is a way to compartmentalize and reuse code by creating objects that have attributes and behaviors that can be based on previously created objects.

Inheritance allows us to work with simple controls like TextBox by taking advantage of their basic behaviors and lets us improve the control by adding new members to control some behaviors that we need to. It's a feature that allows a child class to provide a specific implementation of a method that's already provided by its parent class.

The demo project will show you how to implement the currencyTextBox control in a WinForms project, where you can test anything you want about the control.

Display Currency Values with a Custom Control

In the currencyTextBox class in the JRINCCustomControls project are various custom members that help us achieve the goal of putting the currency-mask to our input text. These are:. It's a read only property that contains our "working text". That means that it contains exactly what the user typed in the TextBox, the text without any mask or formatting. It's a public property that can be assigned and retrieved. It must contain the prefix or currency symbol that we want to precede the input text with.

If empty, no prefix is used on the masked text. It can be assigned through the Properties window at design time. It must contain the separator symbol for thousands that we want our input text to show when masked. If empty, no thousands separator is used on the masked text. It must contain the separator symbol for decimals that we want our input text to show when masked. If empty, no decimal separator is used in the masked text.

It must contain the total places for decimal values that we want our input text to show when masked. Minimum value is 0. It formats the entered text with the desired specifications. Returns a string with the masked text.

This method allows the currencyTextBox to load the formatted text to the Text property. It executes the formatText method, then proceeds to execute the original implementation of the OnLostFocus method. This method allows the currencyTextBox to load the working text to the Text property. In this state, the control is in edit mode please refer to the WorkingText property definition above. After this, it proceeds to execute the original implementation of the OnGotFocus method.

This method brings some validation to ensure that the values entered to the TextBox are only numbers.If in your application have a sign up or sign in functionality, then you need to take input like Name, user ID and password etc. Not only text format it also provides an option like — CheckBox and Radio Button.
