Escape double quotes in asp.net Onclick string

Question

I am trying to insert dynamic data into a onclick property for a control the code looks like this

onclick="openRadWindow('<%#Eval("ID";) %>','<%#Eval("ParentObjectID") %>');"

I cant get it to fire and the trouble seems to be the double quotes, what is the correct method on escaping the quotes so that this fires.

Answer 1

First thing I see is that semi-colon after "ID" - I think that might be causing your problems.

Answer 2

Is the event just not firing or are you getting any javascript errors as well. Also, I would look at the HTML after the page has been rendered and make sure that the server tags are being processed correctly. There are certain uses that cause them not to actually be processed and will remain <%# Eval("ID") %>.

Answer 3

You can do use a format string, like this:

onclick='<%# string.Format("openRadWindow(\"{0}, {1}\");", Eval("ID"), Eval("ParentObjectID")) %>' 

Answer 4

Thanks to all I was able to get it working correctly using a different method. in the code behind I created a function and in the function I put the following code

Return String.Format("openRadWindow({0},{1});", photo.ID, photo.ParentObjectID)

and in the aspx I added onclick="<%#MyFunction(DirectCast(Container.DataItem,Photo))%>
