Viewstate is nice, but you know viewstate data counts 1/3 of my page size.
I need viewstate because I have button control inside my repeater control,
but any idea how can I reduce the viewstate site, it sounds horrible to have
so big viewstate.

It took a bit of extra coding, but I found the you can turn the viewstate
off for many lower level controls and then put your own items in viewstate
that you need to remember on post back. The key is figuring out exactly what
you need on postback and what you do not need. I was able to take my
viewstate from 18K down to 2K of page weight.

ja, right,
I put EnableViewState = false on many controls. But it is a repeater control
and data on repeater control has to be remembered, that is big. that is the
problem.
The situation is that I have a repeater control, inside that control, I have
one button control. When user clicks that button control, server has to do
something based the datarow of that repeater. Do you think I can disable
viewstate on that repeater control???

I have enableviewstate =false on datalists ( I have not tried this on
repeaters, but I think it would work). The trick you must bind the data
source of the datalist during the page_load event. I don't know the techical
reason, but by doing this the events such as onclick are restored. Hope
this helps.

This should say, you must rebind the datalist (or repeater) during the
page_load event even on postback.
So by eliminating the viewstate you increase the backend processing a bit.

It could count more than 90% if you use large datagrids

Eh.. What exactly do you need the viewstate for?? Could you paste a few
lines of your .aspx?

If the datalist/repeater is not user-specific, Cache should be a better
solution to improve the performance. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

I have a page that uses an in-place editable DataGrid that supports sorting and paging. EnableViewState is turned ON. At the top of the page are several search fields that allow the user to filter the results in the grid.
Say you filter the grid for records that have a certain condition set to "NO" (in this case a checkbox). In this scenario the search returns one result. If I then check the checkbox ("YES") and save it, I now get my message...

hi,
I am studying ASP.NET and have few questions -
1) The session ID and values of controls is stored in VIEWSTATE
variable. So now when we put EnableViewState="false" in Page directive and
disable the session state in Web.Config the VIEWSTATE variable is still
maintained and stores some values. Can anyone tell what those values are
for, i.e what other info is stored in VIEWSTATE other than the session ID
and the control values ?

I'm not sure I understand the use of the ViewState.
Do I understand correctly that values of controls are automatically held in
a hidden control called ViewState?
If so, then why can't we get them, or how do we get that value? I always
have to set the ViewState("FirstName") = txtBox.text myself before a
postback is done, otherwise, the value of ViewState("FirstName") is always
empty; there doesn't seem to be a way to retrieve that...
