UWP - How to create a ListView programmatically

UWP - Create a ListView programmatically
The ListView class represents a control that displays data items in a vertical stack in a UWP app. The UWP app developers are using a ListView to display a collection of items stacked vertically or horizontally.

The ListView is an ItemsControl, so the .net developers can put there a collection of items of any type. The ListView data item is displayed as the string representation by default.

The developers can define the ListView control’s selection mode for single or multiple. By default, the ListView selection mode is single. They can toggle the mode by using the ListView class SelectionMode property. The ListViewSelectionMode enumeration value allows multi-selection or disabled selection.

The ListView() constructor initializes a new instance of the ListView class. The ItemsControl class ItemsSource property gets or sets an object source used to generate the content of the ItemsControl. So using this property we can populate the ListView control with items by a string array. The SelectionChanged event occurs when the currently selected item changes.

The following UWP app development tutorial demonstrates how we can create a ListView control programmatically and put it on the app layout. And how we can data bind the ListView control with a String array. Here we also add a selection changed event to the ListView control, so when the user clicks an item from the ListView, it displays the selected item’s text in a simple message dialog.

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 - TextField remove underline

Compose TextField Remove Underline The TextField is the text input widget of android jetpack compose library. TextField is an equivalent widget of the android view system’s EditText widget. TextField is used to enter and modify text. The following jetpack compose tutorial will demonstrate to us how we can remove (actually hide) the underline from a TextField widget in an android application. We have to apply a simple trick to remove (hide) the underline from the TextField. The TextField constructor’s ‘colors’ argument allows us to set or change colors for TextField’s various components such as text color, cursor color, label color, error color, background color, focused and unfocused indicator color, etc. Jetpack developers can pass a TextFieldDefaults.textFieldColors() function with arguments value for the TextField ‘colors’ argument. There are many arguments for this ‘TextFieldDefaults.textFieldColors()’function such as textColor, disabledTextColor, backgroundColor, cursorC...

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...
