Load user control dynamically

I have a master page and a user control. User Control is resgistered on xyz.aspx page. URL rewriting loads xyz.aspx page which in turn loads the UC which shows up on the page/masterpage.

UC builds a side menu.
I added 2 links to my master page. When clicking..i want to call the routine inside the usercontrol to refresh the side menu. Anyway to do this??

First I want to say that I do not know much about "aspx"

I do however have a lot of experience with C# UserControls.

In C# I would simply wrap a routine in a class that inherits a UserControl, and modify the designing like I want it. Here is an example of a class UserControl

public class XYZ_ASPX_PAGE : UserControl
{
   public XYZ_ASPX_PAGE(){
      InitializeComponent();
   }

   public void refreshSideMenu(){
      ....
   }
}


Outside this class I would simply do something like this:

XYZ_ASPX_PAGE page = new XYZ_ASPX_PAGE();

and to add the page to my Main Page, I would do this:

this.masterPage.Controls.Add(page);


I hope this helps

Oh and, once you do this, you can simply do:

this.XYZ_ASPX_PAGE.refreshSideMenu();

to refresh the Side Menu

No, doesnt make sense to me.

1.I have the linkbuttons on a Masterpage:
public partial class MasterPages_Universal : System.Web.UI.MasterPage

So i cant inherit from the UserControl

2. That "refreshsidemenu" is supposed to be in the userContol..right?

3. I did this in click event of the linkbuttons:
   Control FeaturedProductUserControl = LoadControl("~/Controls/ProductFilter.ascx");
  Controls.Add(FeaturedProductUserControl);

This calls my userControl but it doesnt call the "refreshsidemenu"  routine. Anyway to do that?

4. Do you know how I can refresh the entire page when the linkbutton is clicked (maybe this would be easier than loading ONE usercontrol..load the entire page instead of one user control)

I see what your saying now, MasterPage's Control property can not add in System.Windows.Forms.UserControls... What it does add in is Web.UI.Control. Let me research this topic for a while

there has to be somehow dynamically calling this:

I made the UC rotuine public..i tried this:
 Control FeaturedProductUserControl = LoadControl("~/Controls/ProductFilter.ascx");
            Controls.Add(FeaturedProductUserControl);
  FeaturedProductUserControl.<i dont see the rotuine here>

*** I thought about reloading the entire page but there are so many user controls and pieces to this and they're all separate...

Well you can't see the routine since you are dealing with the Object Control.

You need to type cast it to a higher level object in order to see the routines

What my book says on this is the following:

1. You need to create a wrapper class that inherits System.Web.UI.Control
-->Here you provide properties, methods, and events.
2. You need to Override the Renderer Method
-->"Each control must implement this method to generate the HTML that represents the control to the browser. Note that the render method is not called directly; instead, a call is made to RenderControl, which then invokes Render. For controls that contain child controls, the RenderChildren method is available."
3. Use HtmlTextWriter object to generate the HTML Code


I am not sure if this helps you... Sorry I am trying my best

Here is the example that my book uses:
//(1) In herit from the System.Web.UI.Control Class
public class CompanyLogo : System.Web.UI
{
   ... List properties and methods here ...
 
   //(2) Override the Render Method
   protected override void Render(HtmlTextWriter output)
   {
      //(3) Use the HtmlTextWriter to emit html to the browser
   }
}
