Code-Behind Method from dynamically created HTML

Hi All

I would like to know if it is possible to dynamically create asp:LinkButton that post back to code behind with a value in the CommandArgument field.
Meaning I have a list of borrowers and would like to give the user the ability to edit the borrower, but can not use a gridview.

I would like to edit the borrower on the same place I use to add a new borrower.
The code I attached shows what I did, but was not sure as to where to go next or even if I'm doing anything wrong, because my code behind method (also attached) does not have any value in the CommandArgument field.

Any ideas?

Hi there,

The following works:

 
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Me.LinkButton1.CommandArgument = "test"
    End Sub
    Sub DoEditBorrower(ByVal sender As Object, ByVal e As CommandEventArgs)
        Dim x = "You chose: " & e.CommandName & " Item " & e.CommandArgument
    End Sub

Open in new window


 
<asp:LinkButton id="LinkButton1" 
           Text="Edit"
           CommandName="Borrower" 
           CommandArgument=""
           OnCommand="DoEditBorrower" 
           runat="server"/>

Open in new window


If memory serves me correctly, an arguement set as you are trying to is not available on postback due to the page lifecycle, although if anyone would like to prove me wrong feel free.

Regards

Rick

The user that commented did not provide a solution. I did eventually figure it out by myself.
