I have an aspx page that loads a usercontrol. Can that usercontrol
load another usercontrol into part of it?
Thanks,
Marv
 
Yes, just keep in mind that you need to time your events well in the control
event hierarchy. Sometimes an action in a usercontrol that works when
embedded in a page may be a bit off when placed inside another user control.
For example, you pass data from a usercontrol to another one that will show
some more data. You click a link in the parent usercontrol to select a
different set of data to show in the child usercontrol, but the timing of
the events is off so the child usercontrol doesn't update properly and ends
up a step behind the parent.

Hope this helps,

how do you want to load it?
1.dynamicaly in code behind or
2.insert usercontrol tag in aspx/ascx code?

ad 1)
place the folowing directive in the asp code of the parent page or
usercontrol:

<%@ Reference Control="~/Name_of_your_child_control.ascx" %>


create a new instance in code behind by the following code:

Name_of_your_child_control control = (Name_of_your_child_control)
TemplateControl.LoadControl("~/Name_of_your_child_control.ascx");



ad 2)
place the folowing directive in the asp code of the parent page or
usercontrol:

<%@ Register src="Name_of_your_child_control.ascx"
tagname="Name_of_your_child_control" tagprefix="uc1" %>


use the following tag in the asp-code of the parent page/control:

<uc1:Name_of_your_child_control ID="Name_of_your_child_control1"
runat="server" />
