Difference between User Controls and Custom Controls
In the .NET framework, there are two types of controls that are used to build reusable UI components for Windows Forms and WPF applications: user controls and custom controls. Their levels of abstraction and reusability are the primary differences between them.
User controls are simple to create but can only be used within the unique Windows Forms or WPF applications in which they are made, limiting their potential for reuse. They are frequently used to create composite controls by merging existing controls because they were created for certain UI applications.
Custom controls are more flexible and can be used in various applications. Custom controls are also more difficult to develop than user controls.
User controls are better suited for developing reusable UI components that can be used across different applications, whereas custom controls are better for creating UI components particular to a single application.
Read this article to find out more about User Controls and Custom Controls and how they are different from each other.
What are User Controls?
User controls are simple to create and are frequently used to develop particular UI scenarios. For instance, a user control that represents a contact form that has text boxes for the user's name, address, and phone number may be developed. The application might then use this user control whenever a contact form is required.
User controls have the major benefit of being closely tied to the particular application for which they are designed. This implies that they are easily customizable to the particular requirements of the application and that the code of the application can tightly regulate their behaviour.
User controls, however, are only useful within the particular application in which they are generated, restricting their ability to be reused. They must be constructed from scratch for every new application that needs their capabilities, because they are not intended to be recreated across the different apps.
What are Custom Controls?
The Custom control type of the.NET framework enables programmers to create reusable user interface components for Windows Forms and WPF applications. The level of abstraction is higher compared to user control. Custom controls can be used in a wide range of applications.
Custom controls allow developers to construct controls that may be applied to a wide variety of applications. It is perfect for developing UI factors that can be used in a variety of operations. Custom controls are difficult to design compared to the user controls. Custom controls are functional and flexible.
Difference between User Controls and Custom Controls
The following table highlights the major differences between User Controls and Custom Controls −
Characteristics |
User Controls |
Custom Controls |
|---|---|---|
Creation |
It is easy to create |
It is not easy to create |
Toolbox |
User Controls cannot have toolboxes added to them. |
Custom Controls can include a Toolbox. |
Layout |
It is a static layout |
It is a Dynamic layout |
Usability |
It only takes one copy to use it in multiple projects or applications. |
Individual copies are needed for each project or application. |
Flexibility |
There is less user control flexibility. |
Custom control flexibility is more |
Coupled |
It is tightly coupled. |
It is loosely coupled. |
User Interface |
The user interface is fixed and cannot be altered. |
The Custom Controls interface will be changed. |
Conclusion
When deciding between user controls and custom controls, consider the amount of reuse and the level of complexity required for the UI component. A user control might be the best option, if the component is unique to a single application and does not require complex functionality. A custom control might be the best choice if the component needs to be reusable across other applications or requires complicated functionality.
