Instead of using WinForm MessageBox, use the MessageBox provided by WPF and later use MessageBoxResult instead of DialogResult in WPF. like: MessageBoxResult messageBoxResult = System.Windows.MessageBox.Show(“Are you sure?”, “Delete Confirmation”, System.Windows.MessageBoxButton.YesNo); if (messageBoxResult == MessageBoxResult.Yes) //………..
It is not possible. This window is displayed by the browser using the platform’s UI kit. It’s not in the DOM, not visible from the CSS or Javascript, there’s nothing you can do. However, some very simple jQuery code can do the trick. How about $(‘a’).confirm(); ?
You need the modal in your HTML. When the delete button is clicked it popup the modal. It’s also important to prevent the click of that button from submitting the form.

A simple inline JavaScript confirm would suffice: <form onsubmit=”return confirm(‘Do you really want to submit the form?’);”> No need for an external function unless you are doing validation, which you can do something like this: <script> function validate(form) { // validation code here … if(!valid) { alert(‘Please correct the errors in the form!’); return false; … Read more

Since we no longer have to worry about setting the message, it is as simple as: // Enable navigation prompt window.onbeforeunload = function() { … Read more
