OnCommand Link Button

Hi,

in an iteration, I create a LinkButton, add attributes to it, and finally add this LinkButton to the Form Controls.


That is fine, what is not is adding the Command Event. Here is my code

            for (int i = 1; i % 6 != 0; i++)
            {
                if (Convert.ToInt32(Session["CurPage"]) != MyPgd.PageCount - 1)
                {
                    LinkButton NewButton = new LinkButton();
                    NewButton.CommandName = "PageNo";
                    NewButton.CommandArgument = (Convert.ToInt32(Session["CurPage"])+i).ToString();
                    NewButton.Command +=new CommandEventHandler(NewButton_Command);
                    NewButton.Text = (Convert.ToInt32(Session["CurPage"]) + i).ToString();
                    Nav.Controls.Add(NewButton);
                }
            }

    }

    void NewButton_Command(object sender, CommandEventArgs e)
    {
        //throw new Exception("The method or operation is not implemented.");
        Response.Write(e.CommandArgument.ToString());
        //SetPage(Convert.ToInt32(e.CommandArgument.ToString()));
    }

It writes nothing on the page, it is not firing.

Thanks in advance

Andrew,

1) What is 'Nav'?

2) .NET version?  1.1 or 2.0

1) Nav is a Div with an ID of Nav and a runat="server"

2) Version 2.0

That doesn't help :(

Where is this called from?  Does it ever work?  Is there a post-back involved?  Something, anything to go on would help.

All I want to do is dynamically assign a Command event to a link button which I make it the iteration.  Could you paste me a method which you think should work so I can try

Thanks

What is the page configuration?  Do you have a MasterPage?  Where is this code called from?

a dynamically created link button can only be added in page controls collection so nav should be referring controls collection.

Additionallt it appears that
NewButton.CommandArgument = (Convert.ToInt32(Session["CurPage"])+i).ToString();

supplies only a number without a link. supply a link also
