Using SPUser in SharePoint

SharePoint Object Model using SPUser Class

SPUser is actually derived from SPPrinciple, SPUser is main base class which allows in extending its functionality by exposing its member and different properties.SharePoint object model has provided the provision to add the user programatically to sharepoint group or  permissions to user to a list,and it is possible to update the user information or fetch the user information.

The following sample code shows about how to display user permission is he in admin group or normal user

also it has the code to update the user information or giving the permission to a list

WebPart

using System.ComponentModel;

using System.Web;

using System.Data;

using System.Text;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using Microsoft.SharePoint;

namespace SPUserDemo

{

    [ToolboxItemAttribute(false)]

    public class SPUserDemoWebPart: WebPart

    {

protected override void CreateChildControls()

        {

         }

protected override void RenderContents(HtmlTextWriter writer)

{

//Get the user  information

  GetUser(writer)

}

private void GetUser(HtmlTextWriter writer)

{

SPUser SPuser = SPContext.Current.Web.CurrentUser;

if(SPuser.IsSiteAdmin)

writer.Write("<p>Ohh you are Super  admin user'</p>");

else

writer.Write("<p>No you are a normal user </p>");

}

}

}

 //Add  permissions to SharePoint list

Private void AddNewUser()

{

               const string listUsers = @"Users ";

               SPList  Users= null;

                SPSecurity.RunWithElevatedPrivileges(

            delegate {

                          using (SPSite spSsite= new SPSite(“http://sitedemo”)) {

                                     using (SPWeb  spWeb= spSsite.OpenWeb) {

                                                spWeb.AllowUnsafeUpdates = true;

                                              Guid listGuidID = spWeb.Lists.Add listUsers,

                                             "Members", SPListTemplateType.GenericList);

                                              Users = spWeb.Lists[listGuidID];

                                             Users.Fields.Add("User", SPFieldType.User, true);

                                            Users.WriteSecurity = 4;

                                            Users.Update();

                                            spWeb.Update();

                                                                                                      }

                                                                                           }

                         });

}

                   //update user email information

                         using (SPSite spSsite=new SPSite(“http://sitedemo”)) {

                              using (SPWeb  spWeb= spSsite.OpenWeb) {

                                        SPUser spUser = spWeb.AllUsers["ABCUser"];

                                              spUser.Email = " E-mail_Address";

                                                  spUser.Update();

                                                                                                 }

                                                                                                         }

Using SPQuery with ContentIterator.MaxItemsPerQuery in SharePoint

Using SPQuery with ContentIterator.MaxItemsPerQuery

1.       Using SPQuery with RowLimit or with ContentIterator.MaxItemsPerQuery

When we query the SharePoint list and libraries we use SPQuery and some situations because of threshold value limit in sharepoint does not allow the user to query more than or equal to 5000 items,If we use SPQuery  with RowLimit still it is not sure to get the items, but  there is still SharePoint has provide one more way can do it through using ContentIterator.MaxItemsPerQuery.

We also need to use different keywords using depends upon the requirement ContentIterator.ItemEnumerationOrderByID, ContentIterator.ItemEnumerationOrderByPath, or ContentIterator.ItemEnumerationOrderByNVPField.

Sample Code

SPQuery myQuery = new SPQuery();

myQuery.Query =

"<Where><Eq><FieldRef Name=\"Name\"/><Value Type=\"Text\">FieldValue</Value></Eq></Where>"

+ ContentIterator. ItemEnumerationOrderByID;

ContentIterator citerator = new ContentIterator();

citerator.ProcessItemsInList(query,

    delegate(SPListItem item)

    {

        // Code for update or move the list item from one list to another or    //any operation

    },

   // Return true so that ContentIterator rethrows the exception.

    delegate(SPListItem item, Exception e)

    {

        // Handle an exception that was thrown while iterating.

        return true;

    }

);

Creating Site Collection in SharePoint 2013 Preview

What is new features in SharePoint 2013 Preview

This is my first post on SharePoint 2013 preview,the following are the steps to create new site collection in SharePoint 2013,Microsoft has provided more features and enhancements in SharePoint 2013 than the SharePoint 2010.

Please follow the steps to create a new site collection in SharePoint 2013

1.Go to Central Admin and click on create site collection.

2.Screen will appear to create a new site collection,it is found that now it has a provision to create new web application on site collection creation screen as shown in the screen shot.

2. There is new option to select the template type based on SharePoint 2010 and SharePoint 2013 also provided with more number of templates like one is “Developer  Site” and other as shown in the following picture.

3.Select the template which is required to create the site

4. Add the Site Collection Administrator account in primary site collection Administrator and secondary Site Collection Administrator

There is new feature in People picker, more advanced can be able to search people by Active directory,NT Account or even Claim Based User as shown in the following screens shots

Now Microsoft has provided one more feature by displaying the “Sorry to keep you waiting”

Finally 5.Now new site collection is create successfully.

SPList.GetItemById and SPList.GetItemByIdSelectedFields

Using SPList.GetItemById and SPList.GetItemByIdSelectedFields

Difference between SPList.GetItemById and SPList.GetItemByIdSelectedFields

It is very important to consider about the performance when we are query the SPList using SharePoint Object Model, it is not recommended to fetch all items when you are using only one column SharePoint has provided the GetItemByIdSelectedFields which takes the arguments as ID and Field Names which is required.

SPList.GetItemByIdSelectedFields(ID,"Field 1","Field 2","Field3"... so on)

GetItemById method fetches the full item from SPListItemCollection, with all its columns of metadata,even though it may be not required for the any purpose of extra columns still SPListItem hold that values too. So it is required to use in more better way of both GetItemByIdSelectedFields and GetItemById based on the requirements

The following example shows the Employee List which is being query by using GetItemByIdSelectedFields

Let us say the Employee List has three columns

Employee List

Column Name	Type
Employee Number	Number
Employee Salary	Number
Employee Designation	Single Line Of Text

ID	Employee Number	Employee Salary	Employee Designation
1	1123	24000	Senior Software Engineer
2	1124	12000	Trainee
3	1125	50000	Project Manager

The following code fetches

using (SPSite site = new SPSite("http://sampledemo /"))

{

using (SPWeb web = site.OpenWeb()) {

SPList employeeList = web.Lists["Employee List"];

SPListItem  employeeItem= employeeList.GetItemByIdSelectedFields (2,” Employee Salary”);

}

}

Using ReadSecurity and WriteSecurity members in SharePoint

ReadSecurity and WriteSecurity

ReadSecurity

Using the ReadSecurity we can specify the list permission as read only access to list created through programmatically, it will restrict the users for modifications to the items which they are not owners of that items.

WriteSecurity

Using  WriteSecurity we can allow the users to do modifications to list items which they are owners of the items when we create the list by using the SharePoint Object Model programmatically.

Sample demo code explains about the ReadSecurity  and WriteSecurity by creating reimbursement expense list in which employee who wants to claim their expanses will have the permission which they item and others will not have an access ,Creating it through console application.

//Create the SPSite by passing the url

Using(SPSite spSite=new SPSite(“http://demo/sites/HR”);

{

//Create new GUID

Guid  newListGuid=spWeb.Lists.Add(“ExpensesReimbursement”,” Expenses Reimbursement List”,SPListTemplateType. GenericList );

//open  site

Using (SPWeb spWeb=spSite.OpenWeb())

{

//Create new SPList by passing new GUID

SPList newInstanceList  =  spWeb.Lists[newListGuid];

}

}
