UWP - How to use ContentDialog

UWP ContentDialog
The ContentDialog class represents a dialog box that can be customized to contain checkboxes, hyperlinks, buttons, and any other XAML content. The ContentDialog() constructor initializes a new instance of the ContentDialog class.

The following UWP app development tutorial creates a simple content dialog where we put a title, a message, and a primary button. Then we displayed the content dialog by calling the ContentDialog class ShowAsync() method. When users click the primary button then the content dialog hides from the app screen.

The UWP app developers generally used a content dialog to request input from the app user or to show information in a modal dialog. The developers can add a ContentDialog to the app page using code or XAML, even they can create a custom dialog class that's derived from ContentDialog.

The ContentDialog class Title property is used to put a title on the content dialog. But the UWP developers can use TitleTemplate to add a complex title element for their app.

The ContentDialog has three built-in buttons. Those are the close button, primary button, and secondary button. In this tutorial code, we only displayed the primary button on the app interface. The ContentDialog class’s PrimaryButtonText property gets or sets the text to display on the primary button.

The ContentDialog class’s ShowAsync() method begins an asynchronous operation to show the dialog. So finally, we can initialize a ContentDialog instance by using ContentDialog() constructor and display it on the app user interface by calling the ShowAsync() method.

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...
