Access custom attributes in javascript

[Jeremy]

Hi

In javascript how do I access custom attributes that I have added to a RadDatePicker in the code behind?

protected void Page_Load(object sender, EventArgs e)
{
    RadDatePicker1.ClientEvents.OnDateSelected = "LoadChildrenForDatePicker";
    RadDatePicker1.Attributes.Add("children", "someothercontrolid");
}

and the javascript:

function LoadChildrenForDatePicker(sender, e)
{
    if (e.get_oldDate() != e.get_newDate())
    {
        //doesn't work - throws error
        //var childs = sender.getAttribute("children");
        //doesn't work - returns null
        var childs = sender.get_element().getAttribute("children");
    }
}

Hi Jeremy,

Could you please try using the following code snippet and let me know if the issue still persists:

function LoadChildrenForDatePicker(sender, e)
{
   if (e.get_oldDate() != e.get_newDate())
   {
       var id = sender.get_element().id + "_wrapper";
       var childs = $get(id).getAttribute("children");
   }
}

Looking forward for your reply.

All the best,

That works perfectly :)
