I have a user control with a linkbutton_click event loading another user control with a linkbutton_click event of its own. When the second link is clicked, its _click event is skipped. Beyond what the code below what am I missing to have every _click event
captured?
public partial class EditAccount : System.Web.UI.UserControl {
private Page page;
lb.Click += new System.EventHandler(this.LinkButton_Click);
Since you already have an event handler, I don't think you need a new one, I think you casted the event handler to null, so the event handler was not written to the browser in script, at the bottom of the page source code.
Edit:
I don't code in cs, but in vb, I assign the same event handler all the time, but I just use AddHandler. Since I don't have any cs projects that I can use for testing, I can't really check it out.
This might help you use the same event handler, but be able to call different functions depending on which Linkbutton was clicked
It would take a little bit of changing, but you could make properties on your control and use IF statements in the render process to change the rendering of the output. Then, you would not have several separate child controls to contend with.

Sorry I've run you app and it seems that your error means this：
'IntraFluxCMS.Frame' is not allowed here because it does not extend class 'System.Web.UI.Page'.

This article shows the benefit of writing directly to the html output that you need.
