How do I reference a dynamically named control on a UserControl from the Parent Form? (In Winforms).
I have a single parent form but it may load any 1 of around 20 or so UserControls. We will call them ucA, ucB, etc.
Each UserControl has a different number of textboxes, but are named tbA01, tbA02, etc on ucA and tbB01, tbB02, etc on ucB.
How would I reference the value of the textboxes?
I cannot seem to reference the name of the UserControl directly. I know the name of the UserControl as a string, but canot seem to cast it as a control. Likewise with the textboxes on the UserControl. I am sure I can use Control.Find() for the name of the textbox from a simple string. But this doesn't appear to be working, which I assume it will only be looking for controls on ParentForm and not the collection of controls on the UserControl. I assume there would be a method using TryCast or DirectCast and using the Control.Find() in the arguments. But I have not found a solution.
Any help would be appreciated!

Have the UserControls expose public methods or properties that allow anything else that is aware of the UserControl existence, to get or set an internal value (the Text property of a TextBox, for example). The same thing you do with a ComboBox or a ListBox: you don't directly set the Text of the Edit Control of the Items of a ListControl. You use public properties/methods.

I cannot seem to reference the name of the UserControl directly. This is unlikely. You have an instance of the UserControl inside the Form. Did you add the UserControl at run-time? Insert the UCs you build in aList(Of UserControl)and use that to reference the UCs or use Controls.Find() to retrieve the instance(s).

Thank you Jimi! Your answer did help me look at a different method in coming up with a solution. I have it working now. Here is what I used:
Dim matches() As Control
matches = Me.Controls.Find(TblName, True)
If matches.Length > 0 AndAlso TypeOf matches(0) Is TextBox Then
Dim tb As TextBox = DirectCast(matches(0), TextBox)
...
Endif
