Webparts with Ajax

Hi,

I have a repeater which I use to show article teasers on a page. I use custom drop down, which when I click reloads the webpart by passing query string parameters.

In my webpart, I do handling of this stuff to get desired result.

Now, how can I achieve this via ajax so that it does not result in a page reload?

Any pointers to that? I saw "Ajax Use update panel", however I don't how to use that and if by using that can I achieve what is intended?

Thanks for your continuous support!!

Regards,
Chetan

I'd suggest doing that first and seeing what happens. If I remember right from testing, it simply wraps an asp : UpdatePanel around the content of the webpart.

RE:Webparts with Ajax

Hi FroggEye,

Nothing happened I tried. I am clueless how a custom dropdown action will interact with a webpart when in my implementation they don't have any connection. On click of my custom dropdown I call a method like this

window.location.search = 'cat='+ category;

and I handle the queryString cat in my webpart and perform a relevant search. No wonder this results is page-reload.

Thanks

RE:Webparts with Ajax

Hello,

In that case, you would have to take another approach for filtering by category which does not include modifying the querystring. You would either develop a custom Web part or wrap two Web parts in an Update Panel and use the KB article that Juraj provided to share information between them. The page is posting back because you are changing the URL by modifying the querystring. More information about AJAX support is available here. Additionally, repeater and pager update panel example. The update panel property is also available for Web part zones (/CMSHelp/index.html?webpartzoneproperties.htm).

Please let me know if you have any questions.

Best Regards,
