AJAX and web server controls

Please some one explain me the following in ajax.

1) Is it necessary that I have to use html controls instead of web server control in order to support AJAX in my web page?. (I know we can use Magic AJAX – penal control to do the same. But I don't want to use any third party component or library).

2) As per my understanding in AJAX like technology I can send some information to the server and I can get some info from the server based on the info sent. But if I want to add a new row to my web server datagrid control. How can we do this with AJAX. I mean if I add a blank row to my collection class then how will I reflect that in UI.

3) Is there any simple code sample available in the net that demonstrates the web server control manipulation with AJAX.

Hi,

you can use normal web controls when you use Atlas, which is the AJAX implementation/framework from Microsoft.

For more information and quickstartsplease take a look here.

ajax and page_PreInit

Can someone please explain this to me.

Ive been trying to add some controls to a placeholder situated within a updatepanel.

According to microsoft i should create all dynamic controls in the page_preinit method. However when i did this the placeholder object was null.

When i moved the placeholder out of the updatepanel everything worked as expected

I moved the placeholder back into the updatepanel and moved the code to the page_preload method and i can now access the placeholder fine.

Im presuming that anything within an updatepanel cannot be access in the page_preiinit method, but can someone explain why.

Thanks in advance

Hi, I am having the same problem. Did you ever get an answer as to why this happens?

Thanks,
