Question

I have an LinkButton control which I need to add a c# method to. Currently when I use parse control and add the control to the page it changes the call to javascript and I get undefined. I figure a way around this would be to define a javascript function that would call the c# method from the code behind, but I cannot figure out how to do this.

Specfically when a linkbutton is clicked I need javascript to pass the ID of the linkbutton to a C# method.

I have tried this:

foreach (Control Control in myctrl.Controls)
           {
              if (Control is LinkButton)
                   {
                      LinkButton lb = (LinkButton)Control;
                      lb.Click += LinkButton_Click;

                    }
              Panel1.Controls.Add(myctrl);
           } 



public void LinkButton_Click(Object sender, EventArgs e)
        {
   BREAKPOINTHERE>         Console.Write(e.ToString());

        }

It never fires when clicked. here is the code generated:

<a id="dnn_ctr954_ViewPromotions_LinkButton2" href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;dnn$ctr954$ViewPromotions$LinkButton2&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, true))">Get your Free 2</a>

now if I put this in my aspx page, it works fine:

 <asp:LinkButton ID="test" OnClick="LinkButton_Click" runat="server">mybutton</asp:LinkButton>

I get this and it works fine:

<a id="dnn_ctr954_ViewPromotions_test" href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;dnn$ctr954$ViewPromotions$test&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, true))">mybutton</a>

You could call a WebService or PageMethod from javascript written in C#.

Update: Since your using a LinkButton, you could simply define a click handler in your codebehind:

button.Click += button_Click
