ASP.NET / Javascript issue?

Question

I have a asp.net checkbox. I need a javascript confirm popup. If accepted I need to execute the server function.

I add the attributes on page load as:
chkbox.Attributes.Add("onclick", "javascript:ConfirmDelete();")

The server function is:
CheckBox_CheckedChanged

it gets rendered as:
onclick="javascript:ConfirmDelete();setTimeout('__doPostBack(\'CheckBox1\',\'\')', 0)"

and finally the js is:
function ConfirmDelete()
{
if (confirm('Are you sure you want to delete this?'))
{
}
else
{
return false
}
}

it executes my js but then fails to proceed to the server side function. What the heck I am doing wrong? This shouldn't be as hard as I am making it...Thanks in advance!

Answer 1

CheckedChanged event is called before the Click event of the check box. Try reversing the calls i.e call js on CheckChanged event and click to call the server side event.



Other thing you can do is, add the js method ConfirmDelete on the checkChanged event. and change your js to to a postback, your ConfirmDelete method will look like



function ConfirmDelete()

{

if (confirm('Are you sure you want to delete this?'))

{

__doPostBack("<%= RadCombobox1.UniqueID %>","")



}

else

{

return false

}

}



don't add autopostback to your checkbox then. Give this a go and I am waiting to hear back
