Accessing usercontrol in placeholder

David Lozzi

Howdy,

I'm using a PlaceHolder to dynamically display a user control based on a
users selection. This part works great. However how do I get to the
properties of that user control? I have public properties setup but I dont
know how to access that use control...

Thanks!!

Not sure if I fully understood your question, but to access the dynamic user
control here is one way:

UserControl x = (UserControl)Pa nel.FindControl ("<ID assigned to the UC>");
// Use x.<Property Namehere if x is not null

I think tried that, see below...

Dim adv As UserControl = phSearch.FindCo ntrol(DeptCode)

addqry = adv.Attributes. Item("SearchStr ing")

OR

addqry = CType(adv.FindC ontrol("btnSear ch"), Button).Text
and here's the code I use to put the control into the place holder

Dim srch As UserControl = Page.LoadContro l("~/common/advsrc_" & DeptCode &
".ascx")

srch.ID = DeptCode

phSearch.Contro ls.Add(srch)
And then it errors like so

System.NullRefe renceException: Object reference not set to an instance of an
object.

I'm guessing the Attributes.Item is not right to get a Property but I
figured I should be able to get the serach button....

Thanks!!

UserControl and ViewState Error

Greetings! I have a UserControl. On this UserControl is a Panel and a RadioButtonList. The Panel's Visible property is set to false by default. When the user selects a particular RadioButtonList value, a postback is performed and the Panel's Visible property is set to true. Selecting a different RadioButtonList value sets the Visible property to false again. So far, so good. It does, in fact, do this.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
