Hi,

I have bind dynamic table in ASP.net with few controls in it like text box and radio buttons.
Also i have applied class property to respective controls, so that i can access them into the javascript.
By using Class property i can access textbox value in javascript but not able to check radio button is checked or not, as radio button is rendered in Span tag.

There are two ways you can check.

If you use a form:
First, consider that for a set of radio buttons (one doesn't make sense), they all are given the same name= , but can have different id= . They also, should each have a value= . When a button is checked, the data sent to the form (for that name'd group of radio buttons is that of the check item.

Locally, you may use the DOM and the id (which should be unique for every element on you page that has an id !). These have a checked property. You can test this value and determine which is checked.

Here's the DOM check for local usage:

var isChecked = document.getElementById(id).checked;
