swapping web user controls

I have a complicated page, but here is a simple example to show my problem.

I have two web user controls that are being loaded, each with buttons and other asp tags. These are loaded in a certain order. The user, if he/she decides, can swap the order by pressing a button on the page.
My problem, when the user presses the button, the web user controls swap, but anything that was done inside them is lost, i.e. their state is lost.
Can anyone tell me a method of saving their state so that the changes are not lost. I have already tried enableviewstate, but that does not work.

The state is lost because when you remove the user control from the control tree and re-add it back into a different position or a different ControlCollection, the ControlCollection class re-initializes the user control as if it was brand new. Since it is in a different position, the viewstate does not match up and it is discarded.

I've been searching for a way to manually load viewstate into a particular control for quite a while, and have yet to find a solution.

I think I have a way around this problem.

I am planning on loading all my controls into an array, with the viewstate enabled. Then I will save this to a session, and load the controls from there. Hopefully, this will save the viewstate when I move the controls around. And if it doesnt, I may be able to find a method that does it.

Single page with multiple user web controls VS Multiple page with specific user web controls
I have a question regarding single page with multiple user web controls vs multiple page with specific user web controls   Option 1: I am of the opinion to have multiple pages with specific user web controls and use an object to store all the information as the user navigates through the application. And finally at the end, read this object and save all the information to the backend database.   Option 2: My respected team member suggests that we have only one page, with all the specific user web controls and not use an object, instead show/hide the user web controls based ...

I have a web user control being used by another web user control, but the one being used will not display the labels in the resx file.
I am using DotNetNuke version 3.13 (might be 3.013) on a Window's XP machine, SP2. I have what I find to be an extremely odd situation. I have a project called TDS.Controls. This project is a web control library. Each control has its own resx file, which is located in the App_LocalResources directory. Each control inherits from Framework.UserControlBase, just like DotNetNuke's User control in DNN\Controls\User.ascx.vb. As a matter of fact, this control is doing the exact same thing I am trying to do. It is a web user control with its own resx file being used by another web user control (See ...

UpdatePanel within a web user control resets data of controls outside the user control
Hello, I have a usercontrol on my page which displays a running marquee text. It makes use of an UpdatePanel (within the user control) to refresh the marquee text (within the updatepanel) at periodic intervals. For this I added a timer control and its tick event as an async postback trigger for the UpdatePanel. I have a lot of textboxes and dropdown list boxes (all with runat=server) on the page outside the above user control. These are also contained in different UpdatePanels. Problem is, when the user control does a postback to refresh the marquee text, it causes some of...

User Control Within UserControl
If I have a user control A and then inside it a user control B embedded/referenced within it.  User Control A has a panel defined (cpeNewUser) that I want to manipulate from the code behind of User Control B based on some event that happens.So putting this in my code behind of User Control B won't work as it has no idea of cpeNewUser:cpeNewUser.Collapsed = true;So is it because only at runtime they are married up and because of this you cannot access each other's objects at compile time?  How would I get this to work becuase I'm using all user controls inside a AJAX Too...

Use Web Custom control or Web User control?
Friends,  I have a generic aspx page and its functions which is used in many .NET web application. The generic page contains a HTML Div control, server drop down list, server buttons, server textbox and it have different server and client functions to do its tasks for calling aspx pages in web applications. My problem is I do not know whether I should make that generic page as a web user control (but this is tedious because all other application folders must store frontpage aspx and code behind files of the generic page) or as a web custom control (This seems to be good beca...

Server Web User Control or Web Custom Control
Ok, I made a DataGrid I like, stuck it in a Web Control Lib, and then to my toolbar. Now I want to take my nice little control and add it to a greater control, maybe place some buttons around it etc. I could always inherit from it in a new custom control and dynamically add the buttons, but I thought about using a Web User Control. I thought I could easily create a Web User Control, drop on my grid and the buttons on a form, and expose some properties and events, but once I got into it, I got a feeling that this isn't what a Web User Control is for. When designing a control li...
