SPWeb = this.Web always points to Central Administration?

Question

I'm learning SharePoint 2010 and facing a strange problem :

I implement a custom action to add a ribbon button under Documents tab, this button has a command to open a modal dialog in my site which is being located at http://sharepointserver/dev/ . The Url parameter of showModalDialog function is pointed to my application page : test.aspx. The code of test.aspx.cs as below:

     ......................
     protected void Page_Load(object sender, EventArgs e)
    {
        SPWeb web = this.Web;
            try
            {
                SPList list = web.Lists[this.TargetListId];
                SPListItem item = list.GetItemById(this.TargetItemId);
            }
    }

My problem here is this.Web always points to http://sharepointserver, not my current site http://sharepointserver/dev/. This results in list #notfound when I execute SPList list = web.Lists[this.TargetListId]

My Sharepoint project Site URL is http://sharepointserver/dev/ and Feature Scope is being set to Web so I don't know why this.Web doesn't want to give me the current site address. (SPContext.Current.Web also has a same problem)

Any help will be appreciated.

Answer 1

is the link to your application page pointing to http://sharepointserver/dev/_layouts/test.aspx or is the link to your application page pointing to http://sharepointserver/_layouts/test.aspx

It should be the first if is the second this will explain your problem. if not then the question will be is dev/ as sub site or a managed path site collection ?

Answer 2

pls use like this for current web...

SPWeb spweb = SPContext.Current.Web;

or

using (SPSite spsite=new SPSite(SPContext.Current.Web.Url))
{
      using (SPWeb spweb=spsite.OpenWeb())
      {
          // you can access current spweb object
      }
}

It is very strange that you cant use this:

 protected void Page_Load(object sender, EventArgs e)
{
        SPWeb web = SPContext.Current.Web;
        try
        {
            SPList list = web.Lists[this.TargetListId];
            SPListItem item = list.GetItemById(this.TargetItemId);
        }
        catch(exception a)
        {
        }
}

http://msdn.microsoft.com/en-gb/library/microsoft.sharepoint.spweb.aspx

but you can use this:

string url = HttpContext.Current.Request.Url
using (SPSite site = new SPSite(url))
{
    using (SPWeb web = site.OpenWeb())
    {
            try
            {
                SPList list = web.Lists[this.TargetListId];
                SPListItem item = list.GetItemById(this.TargetItemId);
            }
            catch(exception a)
            {
            }
    }
}

can you explain where your putting the code? as i can see page_load event (asp.net code behined) or webpart within feature or within feature reciver?

hope it helps :)
