How can I trigger my function when the selected index in a radio button list changes in ASP.NET without refreshing the entire page?

In the form, I have a table with multiple rows, each containing a RadioButtonList. When a user selects an item in the RadioButtonList, I need to retrieve the index of the selected item without refreshing the page.

Answer №1

A great jQuery solution is:

$('input[type=radio]').click( function() {
     var clickedIndex = $('input[type=radio]').index(this);
     ...implement your logic based on the index...
});

By using this code, you can easily retrieve the zero-based index of the radio button that was clicked within the set. To ensure accuracy, specify a selector that confines them to their container (such as a table) if other radio buttons are present on the page.

Answer №2

One easy solution is to incorporate it within an updatepanel utilizing the AJAX.Net frameworks.

An alternative approach would involve creating custom ajax functionality to handle all desired actions whenever a radio button selection changes.
