How to create Login page in asp.net

Login Web Server Control
In an asp.net application, we can create a user login page by using Login web server control. This Login control displays a user interface for user authentication. Login control renders two TextBoxes to input username and password. It also displays a CheckBox that allows users to indicate whether they want the server to store their identity for the next visit. It allows users to be automatically authenticated for the next visit.

The Login control has many useful built-in properties to customize it. We can change the default look and feel of the login page by using the Login control's BackColor, BorderColor, BorderWidth, BorderStyle, CheckBoxStyle, CreateUserIconUrl, CreateUserText, CreateUserUrl, CssClass, Font, ForeColor, FailureTextStyle, Height, HelpPageIconUrl, LayoutTemplate, TextBoxStyle, TitleTextStyle, LabelStyle, InstructionTextStyle, HyperLinkStyle, LoginButtonStyle, ValidatorTextStyle, BorderPadding, and many more properties. The Login control is fully customizable through templates and style settings.

This Login control is a composite control that renders all common user interface elements needed to authenticate a user in an asp.net application (website).

Login control's CreateUserText property allows us to set the text of a link to a registration page for new users. CreateUserUrl property set an URL for the new user registration page. DestinationPageUrl set an URL of the page displayed to the user when a login is successful.

DisplayRememberMe allows us to show or hide Remember Me checkbox from a login page. FailureText property allows us to set the text displayed when a login attempt fails. HelpPageUrl property set an URL for the login help page. InstructionText property set login instruction text for the user.

We also can change the default text of login control's elements by properties settings such as title text, remember me text, password label text, etc.

The following asp.net example code demonstrates to us how can we create a user login page using Login server control in an asp.net application.

Among the many components provided by Compose, TextField is a critical building block for user input.

In this blog post, we'll explore how to restrict a Jetpack Compose TextField to numeric input only, discussing both basic and advanced implementations. Why Restricting Input Matters Restricting user input to numeric values is a common requirement in apps dealing with forms, payment entries, age verifications, or any data where only numbers are valid. Properly validating input at the UI level enhances user experience, reduces backend validation overhead, and minimizes errors during data processing. Compose provides the flexibility to implement ...

jetpack compose - Image clickable

Compose Image Clickable The Image widget allows android developers to display an image object to the app user interface using the jetpack compose library. Android app developers can show image objects to the Image widget from various sources such as painter resources, vector resources, bitmap, etc. Image is a very essential component of the jetpack compose library. Android app developers can change many properties of an Image widget by its modifiers such as size, shape, etc. We also can specify the Image object scaling algorithm, content description, etc. But how can we set a click event to an Image widget in a jetpack compose application? There is no built-in property/parameter/argument to set up an onClick event directly to the Image widget. This android application development tutorial will demonstrate to us how we can add a click event to the Image widget and make it clickable. Click event of a widget allow app users to execute a task such as showing a toast message by cli...
