Creating the List Programmatically.

In the SharePoint sometimes we need to create a List Programmatically. When we are creating the List programmatically we need to define the List Template Types.

The List Templates Types are available in the SharePoint. For that We need to use this Object i.e. SpListTemplateType .

Out of the Box list Templates are :-

Events	GenericList
Contacts	GenericList
Tasks	GenericList
PictureLibrary	DocumentLibrary

To Create List Programmatically the below piece of the code will helpful.

private static void createList()

      {

          try

          {

              SPSecurity.RunWithElevatedPrivileges(delegate()

              {
                   //here i am accessing the Site

                  using (SPSite mysite = new SPSite(“http://sp2010:1234”))

                  {
                      //I am opening the my Site

                      using (SPWeb myweb = mysite.OpenWeb())

                      {
 //Using the SPListCollection Object I am Geting the all Lists from the Site

                          SPListCollection lists = myweb.Lists;

                          //create new Generic list called "Employee Registration"

                          lists.Add("Employee Registration", "Tracking the All the Employees",SPListTemplateType.GenericList);
 //Using the SPList Object I am getting the Particular List

                          SPList createdlist = myweb.Lists["Employee Registration"];

           //create the column type single line text as a new column called "EmployeeFirstName"

                          createdlist.Fields.Add("EmployeeFirstName", SPFieldType.Text,true);

                 //create the column type Multi line text as a new column called "Employee Address"

                          createdlist.Fields.Add("Employee Address", SPFieldType.Note,true);

                          //create lookup type new column called "States"

                          //Here I am going to get the information from the "Title"

                          //column of a list called "States"

                           

                          SPList lookupList = myweb.Lists["States"];

                          // Creating the Lookup type column

                          createdlist.Fields.AddLookup("Employee State", lookupList.ID,false);

                          SPFieldLookup lookup = (SPFieldLookup)createdlist.Fields["Employee State"];

                          lookup.LookupField = lookupList.Fields["Title"].InternalName;

                          lookup.Update();

                          // get the newly added choice field instance

                          createdlist.Fields.Add("Gender", SPFieldType.Choice, false);

                          SPFieldChoice chFldGender = (SPFieldChoice)createdlist.Fields["Gender"];

                          // set field format type i.e. radio / dropdown

                          chFldGender.EditFormat = SPChoiceFormatType.RadioButtons;

                          // set the choice strings and update the field

                          chFldGender.Choices.Add("Male");

                          chFldGender.Choices.Add("Female");

                          chFldGender.Update();

                          createdlist.Fields.Add("Department", SPFieldType.Choice, false);

                          createdlist.Update();

                          SPFieldChoice objChoiceCol = (SPFieldChoice)createdlist.Fields["Department"];

                          string[] strdata = new string[2];

                          strdata[0] = "IT";

                          strdata[1] = "Marketing";

                          objChoiceCol.Choices.Add(strdata[0]);

                          objChoiceCol.Choices.Add(strdata[1]);

                          objChoiceCol.Update();

                          //making new column visible in default view

                          SPView view = createdlist.DefaultView;

                          view.ViewFields.Add("EmployeeFirstName");

                          view.ViewFields.Add("Employee State");

                          view.Update();

                      }

                  }

              });

          }

          catch (Exception ex)

          {

              ex.ToString();

          }

          finally

          {

          }

      }
