Hi Bertrand,

None of these work with preview 6 of same files. Please let me know if there any significant changes in syntac and what could be going wrong here.

@Thanigainathan: well, jQuery does none of that so it's a tough question to answer...

Hi,

how this is different from JQuery based on the performance ?

Thanks ,

@geek111222: sure, you can do all that already.

The syntax in {{ }} is JavaScript so you can reference *any* object from there. For the current dataitem, you don't even need to dereference and you can do {{ subitem }} directly. But you could also have a global object and reference that.

Nested templates are also already supported. You can reference the parent template's data item using $parentContext.dataItem.

The DataView exposes an itemCreated event that gets a TemplateContext in the event arguments. You can get to the data item by doing args.get_templateContext().get_dataItem().

See weblogs.asp.net/.../instantiating-components-on-template-markup.aspx for an example of that.

Hi,

My question is similar to that asked by 'John Lewicki'. I am trying to bind a dataitem which is basically a javascript object. I want to refer its fields inside my templates. Like :

Is this possible ?

Can it be made possible in future by allowing child templates, that use 'dataitem' from the parent parent as source?

Also, is it possible to attach a client side callback function (just like the ItemDataBound) which can passed the 'dataitem' object as parameter.

@Chris: it's actually not one or the other: jQuery has great selector support, which Microsoft Ajax does not, and Microsoft Ajax has a great component model, globalization and localization support, live bindings, ASP.NET integration and lots of other things that jQuery does not. I use both on many of my projects. A few things to consider: only the core jQuery file is supported by Mirosoft (hence jTemplate is not supported). Also, jTemplate does *not* do what live bindings are doing.

Hi Bertrand I have a couple of questions regarding what I should invest my time learning.

Should I go down the route of Ajax 4.0 or with Microsofts support for jQuery and from what I have seen from buying the book jQuery in Action, the ease at which you can use AJAX with jQuery. Also the use of jTemplates for dong the same as live bindings.

Which way should I go? Or am I being naive and really Ajax 4 has a lot more to offer.

How do you 2-way bind a date? When I utilize this AJAX Client Templating to bind to a textbox and add the jQuery Datepicker, it goes all nuts. Changing the Date on the textbox changes it to a string and doesnt really 2-way bind correctly. Is there some Datepicker associated with this library I can use to test so that it maps to and from the Javascript Object seamlessly?
