UpdatePanel within a web user control resets data of controls outside the user control
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 in a User Control
I have a first user control that contain a second user control. If I cahe the first user control can I still dynamically control the second one or it is cached with the first one therefore can not control it anymore?
When your first control is cached, its rendered out and its output is stored in the cache. On every request to the page containing your control that can satisfy it from cache, the output will just simply be inserted - your first control will never be instantiated or run in that case, so the second one wont be either.

I have created a user control with some checkboxes, and public properties to get the values of these checkboxes. I have also created a second user control using the first user control; this second control also access the public properties of the first one.
My problem is when I implement the second control in an aspx page, if I click at runtime the checkboxes in the first control, I am able to access its public properties from the methods of the second control but the values of these properties are wrong. while at design time, I do not have this problem.

Public Class...Retrieving Data from a Child User Control While in a Parent User Control
I have a User Control that has several Nested (Child) User Controls in it. When I do the final button click (in the Parent User Control) I need to be able to access the Child Controls info (TextBox, DropDownList’s, etc) from the Parent Control. I have tried using the FindControl(“”) function and many others with no success (generally I get a null reference exception when trying to read the data). I have tried referencing the Child Control then using that reference to access the Child element (TextBox, etc) with no success.
Has anyone else done this?

I have validation controls(RequiredField Validator,RegularExpressionValidator) in user controls.User controls are not posting back like the events are not wiring up.If I remove Validation controls in User controls page,user controls are working fine.Can anyone please help me out in getting it fixed.
In the Validation controls, make sure you are setting the ControlToValidate property to the control that it links to.
If you're in .NET 2.0, it's also a good idea to put all the validation controls in the same Valid...User Control controls not created when dynamically creating user control
Have created a user control for displaying and editing a dynamically number of values. The user control contains two labels and an edit box. When dynamically loading the user control I get an error when the control itself tries to change setting on the fields within the user control.
Why doesnt this work? It works okay if I dont load it dynamically but create a user-control-instance in the aspx-page but thats no solution.

I am attempting to have an aspx page that has a user control and within that user control load another user control programatically. I was thinking that I would expose some properties in the first user control and have the user control within that first user control access those properties. Would I do this by inheriting the main user control in the sub user control's class? Also, if I want a method to fire when the user control is loaded, what do I have to do? I was using the Page_Load method, but I don't think that is correct, or it's not exactly what I want. Let me know if I am wrong. :-)
