Hi..

Sorry if this post is misplaced but thourght that it would fit in best here.

What I want to do is call a function, maybe by postback, when a dynamic constructed linkbutton is pushed. This should be done with a parameter and this is the part that I can't figure how to do..

The code I have tried to do this with is:

VB.NET Syntax (Toggle Plain Text) 
  1. 1    Partial Class Webform2
  2. 2        Inherits System.Web.UI.Page
  3. 3    
  4. 4        Dim linkButton1 As System.Web.UI.WebControls.LinkButton
  5. 5    
  6. 6        Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
  7. 7    
  8. 8            'loop that creates linkbuttons
  9. 9            Dim i = 0
  10. 10           For i = 0 To 5
  11. 11               linkButton1 = New LinkButton()
  12. 12               linkButton1.ID = "TesterLinkbox" + i.ToString
  13. 13               linkButton1.Text = i.ToString
  14. 14               linkButton1.CommandName = "test12"
  15. 15               linkButton1.CommandArgument = "The value i want to pass" 'i.ToString
  16. 16               linkButton1.OnClientClick = "javascript:__doPostBack('LinkButtonTest12','test1');"
  17. 17               Panel1.Controls.Add(linkButton1)
  18. 18           Next
  19. 19   
  20. 20   
  21. 21       End Sub
  22. 22   
  23. 23   ' Did not know if i could use panel-events to handle it..???!
  24. 24   
  25. 25       'Protected Sub fisk_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Panel1.Init
  26. 26       '    MsgBox("Panel initialised")
  27. 27       '    Dim lb As LinkButton = CType(sender, LinkButton)
  28. 28       '    If lb.CommandName = "Fisk" Then
  29. 29       '        MsgBox(lb.CommandArgument)
  30. 30       '        Response.Write(lb.CommandArgument) 'your argument here do any thing you want
  31. 31       '    End If
  32. 32   
  33. 33       'End Sub
  34. 34   
  35. 35   ' Handles ordinary clicks on a normal linkbutton
  36. 36   
  37. 37       Protected Sub Kongen_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Kongen.Click
  38. 38           MsgBox("YES")
  39. 39           Dim lb As LinkButton = CType(sender, LinkButton)
  40. 40           If lb.CommandName = "Click" Then
  41. 41               MsgBox(lb.CommandArgument)
  42. 42               Response.Write(lb.CommandArgument)
  43. 43           End If
  44. 44   
  45. 45       End Sub
  46. 46   
  47. 47      Protected Sub LinkButtonTest12_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LinkButtonTest12.Click
  48. 48           MsgBox("Test12")
  49. 49           Dim lb As LinkButton = CType(sender, LinkButton)
  50. 50           If lb.CommandName = "test12" Then
  51. 51               MsgBox(lb.CommandArgument)
  52. 52               'Response.Write(lb.CommandArgument) 'your argument here do any thing you want
  53. 53           End If
  54. 54       End Sub
  55. 55   End Class
  56. 56   
  57. 57




The ASP.NET site looks like this:

  8. 8    </head>
  9. 9    <body>
  10. 10       <form id="form1" runat="server">
  11. 11       <div>
  12. 12           <asp:LinkButton ID="Kongen" CommandName="Click" CommandArgument="Test" runat="server">Kongen</asp:LinkButton>
  13. 13           <asp:HiddenField ID="Target" runat="server" />
  14. 14       
  15. 15       </div>
  16. 16           <asp:HiddenField ID="Argument" runat="server" />
  17. 17           <asp:Panel ID="Panel1" runat="server" Height="331px" Width="511px">
