Remove textbox that added dynamically (VB.Net) - vb.net

Question

I am trying to delete a TextBox control (that added dynamically) in my form through Button_Click event (that I added dynamically too) but I cannot find the exact way to do it. My TextBox will added together with Button control (delete button) when a LinkLabel is clicked. So when added dynamically my textbox.name will be like textbox_1,textbox_2,textbox_3 and along with them is a Button control like btnDel1,btnDel2,btnDel3 (all placed in a Panel control).
My coding goes like this :
Private Sub Button_Click(sender As Object, e As EventArgs)
Dim button As Button = TryCast(sender, Button)
Dim textbox As TextBox = TryCast(sender, TextBox)
'In this case when btnDel1 is clicked, textbox_1 will be removed as well
If button.Name = "btnDel1" Then
PanelOthers.Controls.Remove(button)
End If
End Sub
Button is removed successfully but how do I remove the textbox too? Thanks in advance.

Answer 1

There are a couple ways to do this:
Attach all the relevant controls to the delete button's Tag property.
Create a user control that encapsulates the button and textbox.
Option 1: the Tag property
When you create your controls, add the associated controls to the button's .Tag property:
Dim button As Button = New Button
Dim textbox As TextBox = New TextBox
button.Tag = {textbox}
' Add the button and textbox to the UI surface
Now when the button is clicked you can loop over the associated controls and remove them too:
For Each item As Control In button.Tag
item.Dispose()
Next
button.Dispose()
Option 2: A user control
So isn't a tutorial site.. but you can do your own research on this one.
