Cannot add or remove tables from the DataSet once the DataSet is mapped to a loaded XML document.. - ASP.NET Discussion Boards

i'd thought of doing that, wasn't sure how well it would work in the long run, especially as i'm trying to keep my code clear of javascript and event attributes.

I've just tried to add a field to the top level master page but even that gets ctl00_ctl00 added to it. Is there anyway of getting a single field into the output that has a guaranteed name so that i can tell my javascript where to find the names of all the controls on the page? So far it seems that all the master page setups i've seen serve to make the code less tidy and bring alot of the script back into the html document.

No I don't there is any way of guaranteeing the name since when the html is rendered from the asp.net controls a unique name will be given to it. If you are not using Attribute.Add to add the javascript to your controls, what are you doing? I have found the only way I have been able to get around the whole control namd is to pass the control into my javascript functions.

Masterpages might mess up javascript a bit, but it is much better the the other things I have tried. Usercontrols have their own problem. That was the next best way of doing what a master page does. Honestly I still put some javascript functions in the html of the page that uses it if that is the only page that will use it. The example I gave above was specific to a single page, so I only included it in that page. I figure I don't want to increase my page size by adding it to the master page.

sorry I couldn't be of more help.

i had assumed that if i passed the data into a property of the top level master that my control names would be safe but it seems that didn't work but i'm using that as a temporary measure.

I've now got a hidden field on the masterpage that contains some data that my javascript file can pickup and append to the control names.

I've got a setup method inside my js file that registers the events on the controls i need to hook up to. this now reads the prefixes for the names of the controls from the hidden field on the page. I suppose a benefit of the new model is that i can support multiple instances of the same control on the page for less agro. This method was recommended on several sites, all of which claimed attributes were dead. I was shocked to see ASP splattering my code with script tags (and not even in the head).

Thanks for your help, all help is good at the moment, i seem to be picking up ideas from here and there, many oppose each other and i suspect come are more esoteric than practical, problem at the moment is that i don't know what works and what doesn't.

If you mean fixing Size, you have to set the size in HeaderStyle.

No I mean it behaves like an Excel freeze pane. It fixes the heading and only item scrolls.

System.Diagnostics.Process.Start( <page_name> );,

This one start a new process at server and it depends on WinForm Application or Console Application.Use Response.Redirect();P

I don't think that cancel button has to do anything with that. What is happening when you are clicking cancel button after the error is displayed.

What code have you written for hiding the panel? Is it a javascript?
