Ajax: UpdatePanel to show/hide Gridview

Hi,

Need some directions on Ajax, UpdatePanel and Gridview to achive the
following:

I like to show a Gridview with Data ONLY if the user is interested in
Details, but without a full page reload!
If the page loads, only a summary (eg. COUNT of recs) should be
displayed

Like:

static text
--------------- updatePanel Area
[show records (12) - click for Details]
-------------- end of updatePanel Area

static text

-----if user clicks on "show records" the page should partially
update to display:
static text
--------------- updatePanel Area
[table header - click to Hide Details]
record 1
record 2
record 3
record...
.......
-------------- end of updatePanel Area

static text
A) if the page loads initially, I do not want to hit the database,
except for a fast ( count(*) ) - stored proc. to show #of records
ONLY if the user is interested, I want to execute the full SQL to show
details.

B) if no details are shown, I do not want the Gridview-object to be
instantiated for obvious performance reasons, but show a simple Label
or Hyperlink for (show details)

Anyone have such a component, or can point a way to go?

Thanks,
Reinhard

Hi all, I played with my first bit of AJAX the other week and was pleasantly surprised that I achieved my goal..now I'd like to try something else.. Question... If I have an updatePanel, and lets say I have a button as a trigger which runs a function in my code behind to add a textbox to the updatePanel, when the form is submitted does this control actually "exist" as such on the

I'd like to have an AJAX textbox that after the user fills in, will auto-fill another textbox on the page without having a postback occur. It doesn't have to do any filtering or any other thing like that. I'm fairly experienced with ASP.Net, but new to AJAX. Please help if you can. Thanx.

i have been trying (and sometimes succeeding) to use the modalpopupextender to show various panels of controls on my asp pages. the strange problem that i keep on running into is that sometimes it works, displaying an awesome popup, while other times, it doesn't show a popup at all, but rather just page posts back and the panel becomes visible at the bottom of the page (where it is situated in the designer). what is even stranger to me is that...

Strange problem... Have a gridview on a page (within an update panel) for displaying event dates. GridView loads fine first time around with the PageLoad.

Before AJAX, we were able to focus a cell in a gridview during a fullpage postback. After putting the gridview inside an UpdatePanel, we cannot focus a cell in this gridview anymore. Does anybody know if it is possible to make such focus? Thanks! Bill

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
