ASP.NET / AJAX for beginnners

Hi new friends,

My name is Eduardo. The ASP.NET / AJAX are my new and recent tool to develope programs and website. There are too many doubts about ASP.NET and AJAX. Please, somebody help me?

I have been a lot of pain in my head with AJAX. I'm learning and studying every day, but I have some doubts yet:

1) Do you have some articles that show the good practice to apply AJAX in your ASP.NET application?

2) How many scripts source and update panel I can have in my application or by page?

3) Is the good thing to put one script source and updatepanel in masterpgage?

4) I create an applicaction that have a scriptsource and updatepanel in masterpage. So, There is one label into updatepanel that show the date and timer automaticly without refresh in browser. When I have to create a webpage (aspx) and apply this masterpage I can't use another instance of updatepanel or scriptsource? What's wrong?

Thanks a lot,

Eduardo

Hi Eduardo,

1 - Articles, like videos and tutorials you can find in AJAX homepagehttp://ajax.asp.net

2 - To you have best performance use updatepanels in conditional mode and add the controls that make ajax-postback as Triggers ... You can do this in updatepanel properties... I like to use one scriptmanager in masterpage and use updatepanel with controls that have relations ...

3 - Only scriptmanger in masterpage ... the updatepanels um can "use on-demmand" in your pages.

4 - Modify your masterpage ... remove your contentplaceholder from the updatepanel ... try to use only your label in your updatepanel that is in masterpage...

This might help you

Desculpe meu incomodo, mas é que nao tenho muita experiencia no .NET/AJAX, portanto você poderia explicar novamente?

Grato,

Eduardo

Para ter bom desempenho com seu updatepanel, use em modo condicional, vc altera o modo na propriedade do updatepanel. Também nas propriedades do updatepanel adicione as triggers... que s?o os controles que ir?o atualizar o updatepanel. Entendeu?

Eu costumo usar o scriptmanager na masterpage e coloco diversos updatepanels em minha páginas ... De acordo com a necesecidade ...
