TextBox Arrays in Visual Basic.Net

[Ken01]

Hello
In VB6 and earlier versions it was possible to have arrays of Textboxes, e.g TextBox(0); TextBox(1) etc
which simplified the display of data from arrays or read from a file.
In Visual Basic.Net this feature doesn't seem to be available and I was wondering if there was any equivalent
way to do the same task without resorting to very extensive coding?

Well, there is something like that, but a little different

Let's say you have 2 option buttons (called here Radio Buttons): radAll and radCoRt (this is from my app, option 'All' and option 'County and Route') and you want to 'treat' them as an array (in CheckedChanged event):

Private Sub [blue]RadioButtons_CheckedChanged[/blue](ByVal sender As System.Object, _ 
    ByVal e As System.EventArgs) _[red]
    Handles radCoRt.CheckedChanged, radAll.CheckedChanged[/red]

If CType(sender, RadioButton).Checked = False Then Exit Sub

Me.Cursor = Cursors.WaitCursor

Select Case CType(sender, RadioButton).Name
    Case radAll.Name
        ...
    Case radCoRt.Name
       ...
End Select

Me.Cursor = Cursors.Default

End Sub

The [blue]BLUE[/blue] part of the code may be whatever you want, it is just a name of the procedure. The [red]RED[/red] part is what creates an 'array' (not really) of the controls.

Have fun.

It's still possible to have an array of not just textboxes, but any type of control. Just define the array as the type of the control, like so:

Dim TextBoxes() As TextBox

You can define the size of the array at creation:

Dim TextBoxes(5) As TextBox

Or you can use ReDim and ReDim Preserve to resize the array as needed at runtime.

That's not quite the same thing. An array of controls is not a control array (the latter being what the OP is asking about)

>this feature doesn't seem to be available

Sadly not. There was talk some years ago that Microsoft would bring the feature to VB.NET, but it never happened.
