How to clear the current session data in asp.net

Session Clear() Method
The ASP.NET application uses the session state to store and retrieve the user's data. The application store data when the user navigates ASP.NET pages on a website. We can add an item (variable) to the session state collection using Session Add() method and we can remove a variable from the session state collection by using Session Remove() method.

ASP.NET session state collection store each item as a key-value pair. In this pair, the key is the item name and the value is the specified item's value.

HttpSessionState class’s Clear() method allows us to remove all keys and values from the current session state collection. We can use this method in an ASP.NET application as the Session Clear() method. This method has no parameter and it has no return value. The Session Clear() method exists under System.Web.SessionState namespace.

The following ASP.NET C# example code demonstrates to us how can we clear the current session data in the ASP.NET application using the .NET framework.

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 ...

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...
