asp.net - How to change Panel horizontal align programmatically

Change Panel horizontal alignment programmatically
The Panel represents a control that acts as a container for other controls. The Panel is especially useful when the asp.net developers want to generate controls programmatically, hide and show a group of controls, or localize a group of controls. The Panel’s Direction property is used to display text in the Arabic language.

The following asp.net c# tutorial code demonstrates how we can change the horizontal alignment of a Panel web server control. Here we change the Panel’s horizontal alignment to center and right programmatically. In the below code example, we used the Panel control’s HorizontalAlign property to change its horizontal alignment programmatically.

The Label HorizontalAlign property gets or sets the horizontal alignment of the contents within the panel. The HorizontalAlign property value is one of the HorizontalAlign values. The default value of this property is NotSet.

The HorizontalAlign enumerator value specifies the horizontal alignment of items within a container. Its Center value ensures the contents of a container are centered. And the Right value ensures the contents of a container are right justified.

The Label HorizontalAlign property throws ArgumentOutOfRangeException if the horizontal alignment is not one of the HorizontalAlign values. So finally, here we used the Panel’s HorizontalAlign value to HorizontalAlign.Right to set its horizontal alignment to right and HorizontalAlign.Center to set its horizontal alignment to the center.

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...
