If you are developing a DotNetNuke module and are in the middle of coding and testing that module within a DNN installation and have noticed that you cannot get Visual Studio to enter the Page_Load event of your User Controls and its driving you insane!
Here is the simple solution, make sure your module definition has the Cache Time set to 0. I have found that this is most likely the reason you never see the Page_Load or any other initialization methods hit when debugging your module.

Here are several methods which can be used to navigate between controls within a DotNetNuke module.
#region Navigation Methods

To add help text to the automatically created ‘Help’ link which DNN adds to each of your custom modules you simply need to add a new ‘Resource Key’ to the control’s .RESX file. For example you may have a View.aspx control which is the default display control for your module. Simply click on the designer surface in visual studio for that control, go to Tools > Generate Local Resource. A new .RESX file will be created in your module’s ‘App_LocalResources’ folder. In this file add a new key ‘ModuleHelp.Text’ and set its text value to the text you want to show up in the help control when it opens. The value you give this key can be plain text or html.
To set default pages (where the user is redirected) based on specific events within DNN make configuration changes in the following sections:
Admin > Site Settings > Advanced Settings > Page Management
DNN Page Management
Admin > User Accounts > User Settings >
DNN User Settings
To navigate to another page from within one of your modules use the following code:
using DotNetNuke.Common;
using DotNetNuke.Services.Exceptions;
using DotNetNuke.Entities.Tabs;
protected void lbtnVictorianCross_Click(object sender, EventArgs e)
{
TabController tabController = new TabController();
TabInfo tabInfo = tabController.GetTabByName("Unparalleled Valour", PortalId);
Response.Redirect(Globals.NavigateURL(tabInfo.TabID));
}
