[2005] Page with multiple user controls..

Hey guys, I'm trying to modularise my page abit by doing the following,

Code:

---

<%@ Register Src="suppliers/viewsuppliers.ascx" TagName="viewsuppliers" TagPrefix="supp" %>
<%@ Register Src="suppliers/newsupplier.ascx" TagName="newsupplierform" TagPrefix="supp" %>
<%@ Register Src="suppliers/deletesupplier.ascx" TagName="deletesupplierform" TagPrefix="supp" %>


//And below


                <div id="NewSupplierContainer" runat="server">
                    <supp:newsupplierform ID="NewSupplier" runat="server" />
                </div>
                <div id="DeleteSupplierContainer" runat="server">
                    <supp:deletesupplierform id="DeleteSupplier" runat="server" />
                </div>
                <div id="ViewSupplierContainer" runat="server">
                    <supp:viewsuppliers ID="ViewSupplier" runat="server" />
                </div>

---

And then on Page_Load, I check the arguments,

Code:

---

    protected void Page_Load(object sender, EventArgs e)
    {

        DeleteSupplierContainer.Visible = false;
        NewSupplierContainer.Visible = false;
        if (Request.QueryString["action"] != null)
        {
            ViewSupplierContainer.Visible = false;
            switch (Request.QueryString["action"].ToUpper())
            {
                case "NEW":
                    NewSupplierContainer.Visible = true;
                    break;
                case "DELETE":
                    DeleteSupplierContainer.Visible = true;
                    break;
            }

        }
    }

---

However, my faith in the fact that code that is set to Invisible is not run has been proven wrong. :(

Anyone have any suggestions on how I could make it so that only one of the 3 pages get loaded at a time?

Instead of having the controls always on the page but set to visible or not. Just add the control you need to add at runtime.

Add a placeholder to your page and add your controls to that.

Code:

---

            Control c;
            switch (Request.QueryString["action"].ToUpper())
            {
                case "NEW":
                    c = LoadControl("newsupplierform.ascx");
                    c.ID = "NewSupplier";
                    break;
                case "DELETE":
                    c = LoadControl("deletesupplierform .ascx");
                    c.ID = "DeleteSupplier";
                    break;
            }
            this.placeholder.Controls.Add(c);

Awesome, thanks FishCake, that did the trick. :D
