Solution 4

VB

for each ctrl as control in me.controls
 if typeof ctrl is textbox then
  if not ctrl.name = sender.name then
    ctrl.enable = false
  end if
 end if
next

you will need to put something like this in each textboxes textchanged or similar event

Solution 5

This is how I did:

First I created a common TextChanged event for all the textboxes.

VB

Private Sub TextChanged(sender As Object, e As EventArgs)
	Dim txtEdit As TextBox = DirectCast(sender, TextBox)
	For Each cntrl As Control In Me.Controls
		If TypeOf cntrl Is TextBox AndAlso cntrl.Name <> txtEdit.Name Then
			cntrl.Enabled = False
		End If
	Next
End Sub
}

And then register it :

VB

Public Sub New()
    InitializeComponent();
    AddHandler(textBox1.TextChanged, AddressOf(TextChanged))
    AddHandler(textBox2.TextChanged, AddressOf(TextChanged))
    AddHandler(textBox3.TextChanged, AddressOf(TextChanged))
End Sub

Hope it helped.

How do you get 2 different languages in one Code file? The method is VB and the registration is C#?

Solution 2

try this:

protected void TextBox1_TextChanged(object sender, EventArgs e)
    {
        TextBox1.Enabled = false;
        TextBox2.Enabled = false;

        TextBox3.Enabled = false;
        TextBox4.Enabled = false;
    }

Solution 3

All you need to do is call TextBox1.Enabled = false in your TextBox Changed or TextBox KeyPress events.

Hope this helps
