The lineup includes ASP.NET, Java, Visual Basic, and AJAX

My ASP.NET application originally had a button that triggered VB.NET code execution on the server when clicked.

Recently, there have been changes to the requirements and I've added a new menu that should replace the functionality of the old VB button. After receiving some guidance from Stack Overflow, I was able to manipulate some javascript that performs a postback and runs the button's code. Initially, I thought I could just hide the button and still access its on_click event through JavaScript. However, things did not go as planned!

Now, I find myself in a situation where I need to call a VB sub either from JavaScript or AJAX (as per my boss's instructions). Unfortunately, I am clueless about how to achieve this.

If anyone could provide me with some guidance on how to call a VB.NET subroutine from AJAX or JavaScript on the client-side, I would greatly appreciate it.

Thank you in advance, Jason

Answer №1

Transitioning from a postback scenario to Ajax may not be as straightforward as your boss suggests. There are many factors involved in a postback that may not be replicated in an Ajax call, such as setting server-side values and adjusting visibility. Without seeing the actual code, it's difficult to determine the best approach.

If you're looking for a quick solution, try "clicking" the button again. However, the challenge lies in how invisibility is set - certain types of invisibility can remove the button entirely from the form, making it impossible to interact with programmatically.

Without a closer look at the code, it's hard to ascertain the most effective way forward. Concealing the button with CSS may allow you to interact with it as intended, while using "button.Visible = false" on the server side might not achieve the desired outcome.
