Check if a checkbox is checked in a group of checkboxes in clientside

Question

Please note that the scenario is ASP.NET Webforms + Master - Content page which mess up the ids.
I have, say, three checkboxes

Answer 1

You could do this very easily with a CheckBoxList and a Dado.Validators which provides support for CheckBoxLists. Note this provides client-side and server-side validation.

Example codebehind.aspx.cs

btnSubmit.Click += (a, b) =>
{
    Page.Validate("vlgSubmit");
    if (Page.IsValid) {
        // Validation Successful
    }
};

There are many other useful feature in Dado.Validators worth a look-see.
