[QUOTE="News User, post: 4267016"]
I have a imagebutton in a detailsview, which, when clicked, causes postback
and show or hide some of the rows. (Me.DetailsView1.Fields(4).Visible = true
or false) That's all it does.

In the same detailsview I have other controls : dropdownlist, checkbox and
textboxes etc., all of them are bound to database fields when page is
loaded.

When I changed the values in the dropdownlist/checkbox/textbox, and then
click the imagebutton to show/hide some other rows, all the changes I made
to the dropdownlist/checkbox/textbox are gone (restored to its original
bound value) after postback.

I commented the code that does the show/hide of rows, and found that the
values of dropdownlist/checkbox/textbox  are preserved after postback.

So I wonder if this is normal -- when a row in a detailsview is dynamically
made shown or hidden, then the whole detailsview will have to be databound
again, causing all controls inside this detailsview to retored its original
bound value.

Thanks.
