Hello,
I am having a problem which seems to be explainable
if ViewStates uses not only the IDs but also the
position of each control in the ASPX control tree
to find the corrent viewstate info:
I have an aspx with a set of 10 linkbuttons,
inside an html table cell (basically, page
numbers), and at the end a "Last Page" Link
button.
Another cell has a "Next Page" LinkButton.
All of these have ViewState = True.
Like this:
TR
TD
1 2 3 4 5 6 7 8 9 Last Page
TD
Next Page
My OnPreRender code sets the CommandName for
both the LastPage and NextPage buttons,
and hiddes some of the page numbers when
appropriate. Here I mean setting Visible=False,
not Enable=False.
When I try to navigate the results, and while debbuging
the OnCommand event handler, I find that altough
NextPage.CommandName has in it the value I set it to,
LastPage.CommandName has NOT, it uses the value I set
in the HTML.
I tried putting each of these LinkButtons into
separate TD's, and now LastPage.CommandName has a
correct value.
So: does ViewState use the Control Tree to store the
values??? and if we change it from page to page we
will have problems?
I'll have to set some of those TD's to .Visible=false
in order to get the layout I want, and I'm worrying
the problem will just come back.
I am seriously frustrated with all this webforms/postback/viewstate
things. I start to feel I should just use ASPX like I used to program
ASP.
