VB.net - Target object using string (Object is under tab then panel then splitter)

Question

In php and javascript I can do something like this

If ($a == 1){
  $set_num = 1
} Else {
  $set_num = 2
}

textbox_ . $set_num = "Some text here"
checkbox_ . $set_num = "Some text here"
radio_ . $set_num = "Some text here"

How can I do this in vb.net?

In my design page I have many panel, splitter, textbox, checkbox and other things and please take note that this design is under the panel tab (index 2). What I want is to create a short code (Short as possible) so when the user types in a certain textbox I will know what schedule to activate so every time the user clicks the apply button the system will just send the set that has a last text_change.

This is my code in vb.net and I wanted to use me.controls to call an object in a string, but it's not working

     Dim lab As Label

     For i As Integer = 1 To 10
        lab = Me.Controls("tb_hour_" & i)
        lab.Text = "Test" & i
     Next

By the way, the name of my textbox, checkbox and radio button is something like this

tb_hour_1, tb_minute_1, cb_monday_1, etc. _1 stands for schedule 1 so for the schedule 2 it will be like this tb_hour_2, tb_minute_2, cb_monday_2, etc.

Actually my code is working, the problem comes in when I put the textboxes, checkboxes, etc inside the panel and splitter. The purpose of panel and splitter is just to have a design (my aim is the border).

Currently this is the code that I used to achieved my goal, but my code is so hard to maintain because I nested a condition. That's why I want to apply while loop and target all of the objects in a string

It seems that right now it isn't possible to target an object that is under the panel, and that panel is also under the panel.

I managed to fix this issue by re-creating my design layout, as much as possible I limit the use of panels to one object is under 1 panel only, by doing it like that I can easily target the object using this code.

For Each Ctrl_Panel_Set As Control In Schedule_Tab
        If TypeOf Ctrl_Panel_Set Is Panel And Ctrl_Panel_Set.Name.StartsWith("Panel_Set_") Then
            For Each Ctrl_Lbl_Temp In Ctrl_Panel_Set.Controls
                If TypeOf Ctrl_Lbl_Temp Is Label Then
                    If Ctrl_Lbl_Temp.Name.StartsWith("Lbl_Temp_") Then
                        If Ctrl_Lbl_Temp.Text = "0" Then
                            Panel_Set_Num = CType(Ctrl_Panel_Set, Panel).Name
                            Set_Num = "CSR" & Panel_Set_Num.Substring(Panel_Set_Num.Length - 2) & "^"
                            Return Set_Num
                        End If
                    End If
                End If
            Next
        End If
    Next Ctrl_Panel_Set
