I have a user control inside of default.aspx page, And I have a function in the code behind of user control. I need to call that function from a code behind of default.aspx
I have a 2 part question for web user controls: 1. I want to have an event fire in my user control, but have it be consumed by the parent page, like:
<asp1:Object id="objectMain" runat="server" OnClick="Click" />
Is it possible to do this? Or do I need to make a server control for this functionality? I have it being able to be set in the Page_Init, but I'd like to make it as similar to actual controls as possible. Also, if it is possible to access via the Events section under Properties, that would be good and 2. I am trying to register the web user control as an AsyncPostbackTrigger for another UpdatePanel. With the previous question in mind, is it also possible to set this via the GUI, or does this need to be set programmatically as well?

I have an EDIT.ASPX page and on that page I have some labels and textboxes and a user control. I listed all the related codes you can have a clear picture - not all of the codes are given me a problem. ONLY ONE.
HELP ---> On the Uer control (SiteTemplate2.ascx) I have a DataList that is being populated by the database and that works fine. I have a
CHECKBOX on the user control page each time the user check the CHECKBOX the user control content totally disappears from the EDIT.ASPX page. There is no error message -- I believe this is a post back error but I don't know how to fix it.
Goal: Each time the checkbox called (CHKBSideBar) is clicked on the user control page all of the page content should stay in place that include
EDIT.ASPX Page and the refeneced USER CONTROL. I should be implement a CheckedChanged Function without either of the pages lossing DATA. I need to be able to access post back event from the user control of the Edit.aspx page. When the user click a box on the user control page how do I keep the same Page_Load event on the edit page. I need to reference the Edit page from the user control.
Note: The edit page loads the user control (SiteTemplate2.ascx)SEE CODES BELOW
I know this is a lot and thank you in advanced for your help. I tried to include all the pages that are key players. I must user the user control bacuase the user can select different template so eliminating the user control is not an option.

I have a user control that has several data components
What I want to do is populate the data components based on the parent's page title where the user control is called.
The parent page title is the most logical unique name to each page and so that would be the name that I want to import
as the default value for the data components select parameter. Each page name is stored in my sql data table [Towns] as TownsName.
The general idea is that the control will populate with the towns data based on the page title of the parent page.
<SelectParameters>
<asp:ControlParameter ControlID="DetailsView3" DefaultValue="PAGE TITLE NAME GOES HERE" Name="TownsName" PropertyName="SelectedValue" Type="String" />
</SelectParameters>
I am not sure how to code this correctly, but I am sure it would have to be called in the page load statement.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
SetAttr(DetailsView3.DefaultValue = Parent.Page.Title())<-------THIS OFCOURSE DOES NOT WORK
End Sub
I have spent a couple of days trying to work this one out and have failed to find a workable solution..
I have a user control with contact form and validators, when I add it (user control) to my parent page I get a strange behavior of all buttons within the parent page, Any button I press on the parent page fires the validators of the user control. How can I vallidate the form on my user control only when I press a specific button?
