Hi. I'm trying to add a System.Web.UI.UserControl (Not a
System.Web.UI.WebControl) to an asp.net ajax tabpanel.

Unfortunately it doesn't appear that this is possible. This question could
get very detailed, but I'll keep it short. I have a subroutine shown below
which adds a tabpanels to a tabcontainer(Tabs1) based for each object in a
collection. Then for each tabpanel I try to add a usercontrol named
uWebPage. But when the Page_Load event for uWebPage fires I get null
reference exceptions when referencing controls on uWebpage.

Is this situation I'm trying (adding usercontrol to tabpanel) even possible?
Thanks!

Dim oNewTab As AjaxControlToolkit.TabPanel
Dim uWebpage As uWebpage

For Each oAssociation As UserVideoAssociation In oAssociations
For Each oWebpage As Webpage In oAssociation.Webpages
oNewTab = New AjaxControlToolkit.TabPanel

uWebpage = New uWebpage
uWebpage.DomainName = oAssociation.DomainName
uWebpage.Webpage = oWebpage.Webpage

oNewTab.Controls.Add(uWebpage)

oNewTab.HeaderText = oWebpage.Webpage
Tabs1.Tabs.Add(oNewTab)
Next
Next

Howdy,
Howdy,

Dynamic user controls require a call to LoadControl method instead of
constructor:

For Each oAssociation As UserVideoAssociation In oAssociations
For Each oWebpage As Webpage In oAssociation.Webpages

oNewTab = New AjaxControlToolkit.TabPanel

uWebpage = CType(LoadControl("locationoftheusercontrol"), uWebpage)
uWebpage.DomainName = oAssociation.DomainName
uWebpage.Webpage = oWebpage.Webpage

oNewTab.Controls.Add(uWebpage)

oNewTab.HeaderText = oWebpage.Webpage
Tabs1.Tabs.Add(oNewTab)
Next
Next

Hope this helps
