What's the best way to refresh a usercontrol using a parameter? My
usercontrol is just a DataList that retrieves data from SQL in association
with a public propterty.
I click on a LinkButton in my main page (ASPX), but it still refreshes the
entire page... I only want the UserControl to blink and come back with new
data.
What's the direction I should be looking at? Even if I do it via
JavaScript, how would I refresh the UserControl using JavaScript?
TIA,

My hunch is that this is not possible. Here's why:
1 - JavaScript cannot trigger anything on the server. UC
are run at the server. Therefore JS alone could not
trigger anything for a UC to refresh.
2 - UC ultimately get generated into regular HTML that is
merged with the rest of your page, just look at the view
source HTML from your browser. To re-generate the UC
requires re-generating the entire page.
In terms of solutions, would caching help out? Perhaps
putting the UC in a sub-frame so that it still has its own
page that refreshes?

As a quick fix, what I did was load all those UCs that I need (3 images with
links vertically on the right side), enclosed them all within their own div
tags. So for 4 user controls, I have them all enclosed in 4 div tags. I
used javascript to show/hide these div tags, i.e.
document.getEle mentById("uc1") .style.display = 'block'); or
document.getEle mentById("uc1") .style.display = 'none');
I found this method thanks to this link: http://www.webmatrixproject.net/Foru...1&PostID=21175
As it is done, three images shows up in the UC (as there's only enough room
for it), but if I was to do some pagination in that datalist of images, I
think I will be stuck, but otherwise, I'm OK for the time being...
Still not a be-all, end-all solution, but worth working towards... :-)

I use a series of UserControl that get dynamically created and (all)
docked (fill) on one form panel. Problem is that I have to call
UserControl.BringToFront() more than once to get it to show. This
happens even when only one user control has been created and docked. I
tried with Show(), Refresh() and Invalidate() but had no luck so far.
I gotta be missing something obvious but nothing comes to mind. Any
idea anyone?

Hello,
I'm writing a usercontrol that contains a property named "disabled". It
is set to false by default but there is also another button in the
usercontrol that'll set it to true.
On the main form a number of them are displayed. During the On_Load
event, 1) It'll check to see if the usercontrol is disabled. If true, the
row containing the usercontrol is hidden.
