Server Controls In User Control Are Null When User Control Serves As A Base User Control ?

Jun 4, 2010

I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.

If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?

All I would like to be able to do is include one user control within another! Is this possible? I have spent the last hour searching the internet and it seems that I can't find a single thing.

In classic ASP it would be something like:
<!--#include file="EditProject.ascx"-->

I tried this but no luck!

Web Forms :: LoadControl To Load User Control Is Not Working On Another Computer?

Nov 1, 2010

I created a user control, then use LoadControl to call the user control in a web form. Everything is working fine on my computer. When my work is copied to another developer's computer, the content of the user control does not show. All other pages are working fine.

The only difference I could think of between my computer and another computer is the other computer use ajax-created master page. But this web form that calls the user control does not use any master page.

Web Forms :: User Control Accessing The Parent Page Load Event?

Mar 4, 2010

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.

'*******************************************************************

The user control is being referenced from the web.config file ** Works find! **

EDIT.ASPX Page **-- WORKS FINE!** [Code]....

Web Forms :: Access User Control Properties In Another User Control

Nov 9, 2010

I want to use a couple of instances of the same control on a page. The user control is intended to display a list of records in a repeater. The aim is that the second control will show a list excluding the IDs in the first control The control has a number of public properties, including IDsInThisList, and IDstoExclude. The query will exclude the IDs in the second property.

What I would like to do is get the record IDs from the first instance of the control (IDsInThisList), and pass them to the second contro as the IDsToExclude.

I have a test page where I am setting the properties of the controls in code. As you might guess, it's not working! The first control displays the top 3 items, as desired, but the second display the records 1-7, rather than records 4-10 because it is not receiving the IDstoExclude from the first control When I response write the IDstoExclude from the first control in my testpage, the string is empty. (if I do it from within the control, it shows the IDs)

How can I get the controls to fire in order and pass values to each other?

Screen grab of test page + uc and test page code attached

[Code]....
