change control property from client side and have changes persist on the server
Hi I was wondering if it was possible to change a control's property from the client side with javascript without a post back and have those changes be reflected on the server when a post back occurs.

But when using labels (which will be rendered as <span> tags) then I'm not sure they ...

web forms with client and server side controls??
Hi, I have a form that has client and server side controls. I have a problem in that any client controls (textbox) within the form runat="server" can not be accessed with client side code. Anyone got any ideas why and what work arounds are possible. Regards, Graham. once a form element is inside a <FORM> tag, you can no longer refer to it by its ID alone. you have to refer to it by formname.elementid or document.all.elementid. use document.getElementById(yourtextboxid) to get a ref to the element in the form. using this allows u to bypass the formn...

server-side control inside another server-side control
Hi everyone. I have a requirement where I need to create a custom server side control which will contain a series of ASP controls -- no problem there. However, this component also needs to itself be placed inside a server side control, and then placed into the page...so I'll have a custom server-side component inside a custom server-side component.
