Get ListBox Client Side Set (Changed) values on Server Side in ASP.Net

Herveco

Your example doesn't work, or I have missed something, I work on a websit for information

I have null in my variable

Protected Sub Submit(sender As Object, e As System.EventArgs)
   Dim values As String = Request.Form(ListBox1.ID)
   TextBox1.Text = values
End Sub

Use

Dim values As String = Request.Form(ListBox1.UniqueID)
