Hi all,

I have a page that creates labels programmatically. Each label initializes to a value based on the getcustomer method - see my code below.
Here is my problem, how can I reference the created label to use it?

For example, lets say I want to show it's value in a msgbox.
Example:

VB

msgbox(label1.text) 'Im get an error when I use label1


 Dim i As Integer
 Dim numlabels As Integer

 numlabels = 6
 For i = 1 To numlabels
     Dim myLabel As Label = New Label()
     myLabel.Text = "Value " & getcustomer()
     myLabel.ID = "Label" & i
     Panel1.Controls.Add(myLabel)

     Dim spacer As LiteralControl = New LiteralControl("<br />")
    Panel1.Controls.Add(spacer)
 Next

FindControl function[^]

because you added the control dynamically you can't directly access it. The example below shows how to access such a control by the ID that you have given it. (this was taken directly from the link above)

VB

' This occurs for Repeater1 and originates from LinkButton onClick.
  Protected Sub OnMyCommand1(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs)
    Dim b As LinkButton = sender
    If Not (b Is Nothing) Then
      Dim c As Label = CType(b.Parent.FindControl("foo"), Label)
      If Not (c Is Nothing) Then
        c.Text = "text changed in handler"
        c.ForeColor = System.Drawing.Color.Green
      End If
    End If

  End Sub

thanks for your answer...its brilliant.. I have a follow up question..

I am creating an online exam page with
30 radiobuttons that created dynamically(during run time).
Here is my problem, how will I get the click event of each radiobutton and tag it in my method that will check if the next question is needed to be jump or escaped.

sample :
If im in question 10 and if I answer = "Yes" it will redirect me to Question 15 else it go to the next question or nothing happen
