Hi,

I am having an issue with a module I developed. Anything that is an asp.net Control wont render on the page and is causing errors when I either assign it to a handler, such as a button click event, or if I try to assign a value to it. Such as 

hidUserID.Value = userID.ToString(); 

or 

this.btnNewCategory.Click += new System.EventHandler(this.btnNewCategory_Click);

If I comment out these things, the module will load correctly, including grabbing information from my database tables. The error that shows up is the following:

DotNetNuke.Services.Exceptions.PageLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Modules.QuestList.View.Page_Load(Object sender, EventArgs e) at System.Web.UI.Control.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace --- 

Does anyone know what might be going on? This is a WAP Module developed with C#.NET. My thinking was that it has something to do with the designer.cs file causing some issues.

Thanks,

Chris

Hi

I think you need to go to the properties of project and - set  start url, project url and click on virtual directory button then set override application root url.

 Then build your project again and check.

Thanks

Hi Sibabrata,

My Start URL is currently already set to http://localhost/dotnetnuke
ProjectURL is http://localhost/dotnetnuke/desktopmodules/WozList
and override application root URL is checked and has a value of http://localhost/dotnetnuke

Are these correct?

Chris

So I just noticed something, becuase after manually putting information into the database to see if some stuff was running correctly, my styles were not working either. So I copied the module.css file out of my server on my live site, and opened the file and it was blank. I did the same for the view.designer.cs file and it is also basically blank, there was some basic stuff in it with setting the partial class etc.

I tried copying my test module.css, which I confirmed has the correct styles in it, to my live site. reload, still not showing my styles. When I recopy the file out of the Live site and open it is blank again.

I am pretty sure that this is the reason that I am having errors with the ASP.NET controls.

Anyone have any ideas?

Thanks,

Chris
