asp.net - How to submit a form with a LinkButton

Submit an asp.net page by LinkButton control
LinkButton is an ASP.NET web server control. LinkButton control display as a hyperlink-style Button control on the web page. LinkButton server control has the same appearance as a hyperlink control but it has the same functionality as a regular button control. We can render LinkButton control as a Submit button or as a Command button on the web page. So we can submit an ASP.NET page to the web server by LinkButton control.

Submit button does not have a command name associated with it. By default, LinkButton control is a submit Button that simply posts the web page back to the server. We can provide an event handler for the LinkButton Click event to programmatically control the action performed when the submit Button is clicked. The LinkButton Click event occurs when the LinkButton control is clicked.

The following ASP.NET C# example code demonstrates to us how can we submit an ASP.NET page to the web server using LinkButton server control in an ASP.NET application. In this example, we created a LinkButton as a submit Button and we post the page to the web server when someone clicks the LinkButton control. After clicking the LinkButton, the web page displays user-submitted information on the web browser.
LinkButtonSubmit.aspx

<%@ Page Language="C#" %>

<!DOCTYPE html>

<script runat="server">
    protected void LinkButton1_Click(object sender, System.EventArgs e)
    {
        Label1.Text = "Hi " + TextBox1.Text;
        Label1.Text += "!<br />You are a " + RadioButtonList1.SelectedItem.Text;
    }

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...
