exposing the methods of your dynamically created usercontrol

Question

Hi I'm completely new to all this so my apologies if this may sounds like a stupid half-a-zillion times asked question. BUT..... This is what I'm trying to do. I have a main aspx.net page that places one of my usercontrols dynamically on the page. The number of controls being added depends on the number of records in a database. Since I use the usercontrol to display the data in the database(in the form of a table) I need set-methods to send the data to the control. Unfortunately the main aspx.net page doesn't seem to recognize the property and keeps telling me: 'Titel' is not a member of 'System.Web.UI.UserControl'. -------------------------------------------------------------------------------------------- This is the code of the main aspx.net page (sarcastically named simple4.aspx): --------------------------------------------------------------------------------------------- 'imagine yourself there are some declarations here Sub page_load(Sender as Object E as EventArgs) If not IsPostBack then ' 'bunch of ado.net related stuff ' 'putting the data in an arraylist (works) for y = 0 to intRowCount - 1 Row = Tempdbds.Tables(notebooks).Rows(y) Friends.add(row.item(titel)) next for y = 0 to intRowCount - 1 'Here I dynamically make my uc Dim temp As UserControl = LoadControl(simple3.ascx) 'the cursed statement that won't compile for simplicity I send help instead of a friends(index) value !!!! X-| temp.Titel(help) Controls.add(temp) next end if end sub ----------------------------------------------------- This is my (simplified) uc named simple3.ascx ----------------------------------------------------- dim strTitel as string 'my hopeless attempt at getting the method exposed apparently not correct Public Property Titel() As String Get Return strTitel End Get Set(ByVal Value As String) strTitel = Value 'lblTitel is a label in the body lblTitel.text = strTitel End Set End Property Thx for any help.

That's really weird. Maybe it tells that .NET is easy enough not to teach it =D

Thank you very very very much. I got it working now the way I wanted to and this will surely aid me in the rest of my schoolproject. (they teach ya javabeans egb jsp but then they make you build .NET aps :-?)

It's because you have the following code : Dim temp As UserControl = LoadControl(simple3.ascx) An instance of class UserControl doesn't have property Titel: the class of your own has. I suggest that you write your controls using code-behind technique and declare Titel property in codebehind file. (Okay you can do it without you have to give classname attribute to the control) Then you can write Dim temp As MyControl = LoadControl(simple3.ascx) now temp.Titel will be there. Finally are you sure user controls are best for this situation? I'd check the possibilities of datalist / datagrid and templates.

temp.Titel(help) should be: temp.Titel = help But this won't help much... (if not to say nothing changed)
