How to load user control within another user control?

I have many user controls. One of them is Banner.ascx which I may load it
within anothers.
I tried to load Banner.ascx within Footer.ascx but  I got an error
"The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."

Any ideas?
Any answer is appreciated highly.
Thanks.

Hi friend,

Check the following paragraph, perhaps it can help you,

 

Does your application run on .NET Framework 2.0 or above?

If so, from the error message, the cause of the error is that you are trying to access a property on a child control in OnInit phase, which isn’t guaranteed to work.

So you should try to check if you have modify the property in the control’s OnInit phase, if so, just remove it.

and here is the original link,

I'd like to load a user control, that has its code-behind compiled into an assembly, from within another user control. The user control you see below is used as a page template, contained within a .aspx file. There is no code in the MySite.Web.UI.Pages.PageTemplate class. <%@ Control Language="C#" Inherits="MySite.Web.UI.Pages.PageTemplate" %> <%@ Register TagPrefix="mysite" Namespace="MySite.Web.UI.Controls" Assembly="MySite.Web" %> <div id="container"> <div id="pageHeader"> ...

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

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 ...
