Sharepoint : application page could not find SPList

Question

I have an application page: ApprovedReassessments with this url :

http://.../Sites/spain/_layouts/pw/ApprovedReassessments.aspx

and I have a library : DropDownLibrary with this url:

  http://.../sites/Spain/DropDownLibrary/Forms/AllItems.aspx

when I try to call this library in the application page :

     string DROPDOWNLIBRARY_FIELDS = "<FieldRef Name='{0}' /><FieldRef Name='{1}' /><FieldRef Name='{2}' /><FieldRef Name='{3}' /><FieldRef Name='{4}' /><FieldRef Name='{5}' /><FieldRef Name='{6}' /><FieldRef Name='{7}' /><FieldRef Name='{8}' /><FieldRef Name='{9}' /><FieldRef Name='{10}' />";
    SPQuery objQuery = new SPQuery();
    objQuery.ViewFields = string.Format(DROPDOWNLIBRARY_FIELDS, SharePoint_Assessment_Fields.AGENTID_FIELD, SharePoint_Assessment_Fields.ID_FIELD,
                         SharePoint_Assessment_Fields.CREATED_FIELD, SharePoint_Assessment_Fields.SALESFORCECASENUMBER_FIELD, SharePoint_Assessment_Fields.COUNTRY_CODE_FIELD,
                         SharePoint_Assessment_Fields.FILELEAFREF_FIELD, SharePoint_Assessment_Fields.FILEREF_FIELD, SharePoint_Assessment_Fields.ASSESST_STATUS_FIELD,
                         SharePoint_Assessment_Fields.REVIEWTYPE_FIELD, SharePoint_Assessment_Fields.PAXORCARGO_FIELD, SharePoint_Assessment_Fields.SUBMITTEDDATE_FIELD
                         );
  objQuery.Query = "<Where><And><Eq><FieldRef Name=\"ID\"/><Value Type=\"Integer\">" + salesforceCaseNumber + "</Value></Eq><Eq><FieldRef Name=\"ID\"/><Value Type=\"Integer\">" + agentId + "</Value></Eq></And></Where>";                   
 SPList dropDownList = this.currentWeb.GetList(SPUrlUtility.CombineUrl(this.currentWeb.ServerRelativeUrl, DocumentLibrary.DROPDOWN)); ...

the last line return this error :

 cannot complete this action please try again 

PS : I have a webpart who call the same library, and it works but not in application page any idea please ?

Answer 1

currentWeb.Lists["DropDownList"]

Lists takes the title or the list id. What you're passing in looks like the partial URL.

Answer 2

Check http://<url>/FormServerTemplates

Go to the above URL > Settings > Library Settings > Permission to this Library and provide permission to your user.

Also, check if it's just for one library or its happening for all the library. looks a permission issue.

Answer 3

I tried this solution and it works :

using (SPSite curSite = new SPSite(SPContext.Current.Web.Url))
            {
                curSite.AllowUnsafeUpdates = true;
                using (SPWeb curWeb = curSite.OpenWeb())
                {
                    curWeb.AllowUnsafeUpdates = true;
                    SPList list2 = curWeb.GetList(SPUrlUtility.CombineUrl(curWeb .ServerRelativeUrl.TrimEnd('/'), "/Lists/ListName"));
                    curWeb.AllowUnsafeUpdates = false;
                }
                curSite.AllowUnsafeUpdates = false;
            }
