asp.net - How to change HyperLink image url

Change HyperLink image URL programmatically
The HyperLink is a control that displays a link to another Web page. The asp.net developers use the HyperLink control to create a link to another Web page. The HyperLink web server control is typically displayed as text specified by the Text property. But the asp.net c# developers can also display an image on it specified by the ImageUrl property.

The following asp.net c# tutorial code demonstrates how we can change the HyperLink control’s image URL programmatically. In the below example code, we change the HyperLink control’s image URL programmatically using its ImageUrl property.

The HyperLink ImageUrl property gets or sets the path to an image to display for the HyperLink control. The ImageUrl property value is a String that represents the path to the image to display for the HyperLink control. The default value of this ImageUrl property is an empty string ("").

When asp.net developers set both the Text and ImageUrl properties, the ImageUrl property takes precedence. If the image is unavailable, the text in the Text property is displayed on the HyperLink control.

So finally, using the HyperLink control’s ImageUrl property the asp.net c# developers can change the HyperLink’s image URL programmatically.

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.

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...
