Hi Rod,
Thanks for your followup. I think the routine you described in the last
reply is correct and could be a means to implement what you want. However,
I've another means if your page is not very complex. I think you may try
put those things all in the same page and when different linkbutton such as
(new, delete or update) is clicked , the page display the related part and
hide the others. In ASP.NET web page , you can use the Panel control to
contains other sub controls and you're able to show or hide a control
freely. Thus, as for the problem you mentioned, I think you can provide two
panels one contains the controls and elements which is to be shown at "new"
situation, and the other panel contains the thing which is to be shown at
"update" situation. And when "New" link is clicked, you show the "new"
panel and hide the "update" panel. Also, the same when "update" panel is
clicked. If so, you may avoid using multi pages or transfer parameters
between different pages.
To make this clearly, I've made a simple sample page , you may have a check
to see whether this is suitable for your situation:
