Question

i have the following problem:
i work in web application and only today. any control i put on the page, when trying to access it from behind code. it doesn’t appear at all. what are the probabilities and reasons for this problem.
note:
i work from a thin client. they make some maintenance on their server today. and after that i find this problem.

the previous controls on my page can be accessed normally with out any problems.

Answer 1

See if the controls have an ID this might sound stupid but perhaps yesterday someone
created the view with a snippet label *tab *tab and forgot to add an id

Below result of label *tab *tab ..

 <asp:Label Text="text" runat="server" />

Should be

 <asp:Label Text="text" ID="lblInfo" runat="server" />

Else check the attributes of the page / controls / codebehindfile
