THis is more like an architecture question. I am new to .NET and would like to get more info on the page design side.
Suppose there is a classic 4-region page layout:
Upper-left: logo
Upper-right: banner
Down-left: Navigation bar
Down-right: Content
Within the content region, there are two sections: data input section on the upper half, and the data display section in the lower half.
In the upper section, there is a label, a text box, and two buttons (DISPLAY and NEXT)
You enter the criteria into the text box and press the button DISPLAY next to it. The data will be displayed on the bottom section (dataGid, for example).
If you press button NEXT, the content will move to the next page (a different page layout in the content region).
There are two design apprioaches, as I know of:
1) Everytime the data is changed, the page will be "re-pained" entirely.
2) Only the data content region dynamic, while keeping the rest of the page static.
How do you do this while keeping the code (such as Page_Load) slick? Anyone can suggest the best practice?

Actually, I'd like to know how to handle the page dynamics, should I reload the whole page or just the data content.
If the to reload the whole page, how to make the code slick. Suppose LoadAnyPageStuff() is to load the banner/logo/menu, how do you implement it in the method? We used to do it quite easily in ASP, but want to know how to do it in C#/ASP.NET.

If you're planning on using something like the DataGrid to display your data results, you can always use the
If Not Page.IsPostBack
check and only bind your dataGrid when you click "Display". The reast of your page should stay as it was before you clicked the button. This would especially be the case if your logo/banner/menu/etc are custom controls that do not relay on code based in the content pane to display.
Something like:
Page_Load()
If Not Page.IsPostBack Then
'Load page
LoadAnyPageStuff()
BindGrid()
Else
'bind grid based on textbox
BindGrid()
End If
End Sub
