Afternoon All,
I'm really starting to get my teeth into this .Net thing and, for the most part, am getting it pretty good. Every once in a while I run into something I cannot find through my readings so please bear with me.
I have a page that receives some data using the "string var = Request.Form["this"]" syntax. My problem is that on the same page, I have some hidden fields. I want to populate the hidden fields with the values I have received so that I can pass the fields to another page, which at this time is still .asp. I know I could use another method by reading the PreviousPage controls but I cannot get the hidden fields values to populate.
Additionally, in the Intellisense, I don't see the hidden fields in the list.
If I am doing this wrong any help or direction would be greatly appreciated.

There's a server control, asp:Hidden or something. If you use that, you will be able to set values on the server. The only thing is, the client id for a server control is not the id you enter in the IDE, so you need to write the ClientID value to a variable if you use it in javascript.

They must have hidden that control from my list. 
Thanks Christian for the road map.
I'm merrily along my way.
If so inclined, (could you expand on your point about the ClientID. Not quite sure I understand. I understand about the variable assignment but the "id is not the id" part that confused me.)

On the server side, you may call it 'myHiddenId' ( I am not recommending that you do ). On the client side, it will be called something like 'form1_innercontrol_myHiddenId' ( that's just a bad example, not a real world one ). So, if you use document.getElementById to access the control from javascript, you would need to write a variable into your page in javascript so you have the right Id to work with, and you can get it from the ClientID property of the server control.

Hi
how can emulate button click in a site in my ASP.NET code?
(button is in another site)
tanks for your reply.

You can't. Your ASP.NET code will always run on your server, why would you want to control another site there ? Your client side code needs to be javascript, and if you're trying to interact with another site, it means you have it open in another browser instance to the one that contains your javascript code.

Hi to all,
currently we're developping a tool in asp.net that will allow the user to open an image with the editor they want we're using the "open-with" dialog from windows with an javascript call on a clientclick. this works no problem
now after they open the file the asp.net page will be sitting and waiting for the image to be modified and saved (and not waiting for the editor to be closed, because some programs like photoshop take quite some time to open) so I've used the filesystemwatcher. I can catch the event with out a problem on the server side of the page but I can't seem to reload the page with the new image....
I know the call has been done asynchronocly and that this probable causing the problem. So I tried to use a clientscript with a history.go(0); and write it as a startup script but this doesnt seem to work either....
anyone got an idea? I would just need to reload the same page, with the same image when it is modified by saving it
Thanks in advance
its our widgets that make us men

Simple answer is you can't (without using hacks/workarounds). The web browser is disconnected from the server so doesn't receive these events. One solution would be to have the page periodically reload the image using a refresh in javascript.

That's not a useful description of the problem. What does it do, and how does that differ from what you expected? Do you get any error message?
Why are you using a LinkButton? That will do a postback, so your javascript will never be called.
Experience is the sum of all the mistakes you have done.

hi
after you insert a button in dataGridView , you can write follow code in onClientClick property :
OnClientClick="return confirm('are you ... ?')"

Just a quick question:
In ASP.Net are you encouraged to use controls such as the Panel for layout, rather than divs and whatever else you'd use in a plain olf HTML file?
Me: Can you see the "up" arrow?
User:Errr...ummm....no.
Me: Can you see an arrow that points upwards?
User: Oh yes, I see it now!

For me, I didn't have a need to use it, i am using tables as layout. Each control has it's own good and bad side.

You should use divs and stylesheets for web application page layout. Only use tables if you are wanting to display tabular data.
Panels are useful for example if you want to hide/unhide a number of controls. Easy to do if controls are on a single panel, just set panels visible property to true or false.
Take a look at http://asp.net/learn/videos/video-188.aspx for free video on CSS (Cascading Style Sheets). This gives an example of how to use divs and a stylesheet to layout a webpage in asp.net.
