How to show login status in asp.net

LoginStatus Web Server Control
.NET framework LoginStatus Class allows us to detect the user's authentication state and toggles the state of a link to log in to or log out of a website. To allow users to log in to an ASP.NET application that uses forms authentication, we can use the LoginStatus server control to detect a user authentication status.

When this control found a user is not authenticated then it displays a Button to move the user to the login page. If the control found a login user then it displays a logout button for this user to log out from the website.

We can customize the default look and feel of LoginStatus control by setting its various properties such as BackColor, ForeColor, BorderStyle, BorderColor, BorderWidth, CssClass, Font, Height, Width, etc.

LoginStatus control's LoginImageUrl property allows us to set the URL of the image used for the login page link. LoginText property set the text display for the login link.

The LogoutText property set a text used for the log-out link. The LogoutPageUrl property set an URL for the logout page. The LogoutImageUrl property set an image URL to display as a logout Button. The LogoutAction property allows us to set a value that determines the action taken when a user logs out of a website with LoginStatus server control.

LoginName is an ASP.NET web server control that displays a user's login name if the user has logged in using asp.net membership. If the website uses integrated windows authentication then the LoginName control displays the user's windows account name.

The following ASP.NET example code demonstrates to us how can we show a user's login status in the ASP.NET application using LoginStatus web server control.

Restricting Jetpack Compose TextField to Numeric Input Only

Jetpack Compose has revolutionized Android development with its declarative approach, enabling developers to build modern, responsive UIs more efficiently. Among the many components provided by Compose, TextField is a critical building block for user input. However, ensuring that a TextField accepts only numeric input can pose challenges, especially when considering edge cases like empty fields, invalid characters, or localization nuances. 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...
