SharePoint WebControls

In this post I’m going to tell you how to use SharePoint’s web controls in our custom code. It is very easy to use and it gives look and feel of SharePoint’s default forms. First we have to add the reference for Microsoft.SharePoint assembly and add
using Microsoft.SharePoint.WebControls

Assembly: Microsoft.SharePoint (in microsoft.sharepoint.dll)
Namespace: Microsoft.SharePoint.WebControls

SPWeb web = SPContext.Current.Web;
SPList list = web.Lists["ListName"];

// Display Lookup field with Multiple selection enabled
MultipleLookupField mlkpfield = new MultipleLookupField();
mlkpfield.ListId = list.ID;
mlkpfield.FieldName = "MultiLookup";
mlkpfield.ControlMode = SPControlMode.New;
this.Controls.Add(mlkpfield);

// Display List View Toolbar
ViewToolBar toolbar = new ViewToolBar();
SPContext context = SPContext.GetContext(this.Context, list.DefaultView.ID, list.ID, SPContext.Current.Web);

toolbar.RenderContext = context;
this.Controls.Add(toolbar);

// Display List View
ListView lv = new ListView();
lv.ListId = list.ID.ToString();
lv.ViewId = list.DefaultView.ID.ToString();
this.Controls.Add(lv);

// Display DateTime Picker

DateTimeControl dtc = new DateTimeControl();

dtc.DateOnly = true;

dtc.UseTimeZoneAdjustment = true;

this.Controls.Add(dtc);

// Display Rich Text Editor for Multiline Text field

rText = new RichTextField();

rText.ControlMode = SPControlMode.New;

rText.ListId = list.ID;

rText.FieldName = "MText";

this.Controls.Add(rText);

// Display Lookup field with Multiple selection disabled

LookupField lkpfield = new LookupField();

lkpfield.ListId = list.ID;

lkpfield.ieldName = "Demo";

lkpfield.ControlMode = SPControlMode.New;

lkpfield.DisplaySize = 30;

this.Controls.Add(lkpfield);

// Display Cancel button for list

MultiPageGoBackButton btnmpg = new MultiPageGoBackButton();

btnmpg.ControlMode = SPControlMode.New;

btnmpg.ListId = list.ID;

this.Controls.Add(btnmpg);

// Display ListView Selector dropdown

ListViewSelector lstViewSel = new ListViewSelector();

lstViewSel.RenderContext = context;

this.Controls.Add(lstViewSel);

// Display ListView By Query

ListViewByQuery view = new ListViewByQuery();

SPList list1 = web.Lists["AskedQuestions"];

view.List = list1;

SPQuery query = new SPQuery(view.List.DefaultView);

query.ViewFields = "<FieldRef Name='Title'/><FieldRef Name='QuestionDescription'/>";

query.Query = "<Where><Contains><FieldRef Name='Category'/><Value Type='Text'>IT</Value></Contains></Where>";

view.Query = query;

view.DisableFilter = true;

view.DisableSort = true;

this.Controls.Add(view);

// Render Edit Item button

EditItemButton btnEdit = new EditItemButton();

btnEdit.ListId = list.ID;

btnEdit.ItemId = 2;

btnEdit.Text = "Edit";

btnEdit.ControlMode = SPControlMode.Edit;

this.Controls.Add(btnEdit);

// Render URL field

urlField = new UrlField();

urlField.ListId = lstLink.ID;

urlField.FieldName = "URL";

urlField.ControlMode = SPControlMode.Edit;

urlField.ItemId = 5;

this.Controls.Add(urlField);

urlField.DisplaySize=50;

//Displays Document Uploaded by Current User on a Site as a Web Part

usrDocs = new UserDocsWebPart();

this.Controls.Add(usrDocs);

// Render User field

usrField = new UserField();

usrField.ControlMode = SPControlMode.Edit;

usrField.ListId = list.ID;

usrField.ItemId = 5;

usrField.FieldName = "Created By";

this.Controls.Add(usrField);

usrField.IsValid  ---------- to check if field is required

// Render Save button on New/ Edit Form but I'm not able so save Data Using this button

btnSave = new SaveButton();

btnSave.ListId = list.ID;

btnSave.ControlMode = SPControlMode.New;

btnSave.Text = "Save";

// Render Form Toolbar  (with attach file link and '* indicates a required field')

FormToolBar ftbar = new FormToolBar();

ftbar.ControlMode = SPControlMode.New;

ftbar.ListId = list.ID;

this.Controls.Add(ftbar);

//HTML = ftbar.GetDesignTimeHtml();

// Render Edit Document Link

EditDocumentLink edlink = new EditDocumentLink();

edlink.DocumentUrl = "http://indelplmcdr/Shared%20Documents/TickerTest.aspx";

edlink.Text = "Edit Doc";

this.Controls.Add(edlink);

// Render Action Menu

ActionsMenu AcMenu = new ActionsMenu();

SPContext context = SPContext.GetContext(this.Context, list.DefaultView.ID, list.ID, SPContext.Current.Web);

AcMenu.RenderContext = context;

// Render Recent Changes Menu
RecentChangesMenu rcmenu = new RecentChangesMenu();
rcmenu.RenderContext = context;

// Insert value in Lookup field
SPFieldLookupValue lkpvalue = new SPFieldLookupValue();
lkpvalue.LookupId= (int)n;

SPFieldUserValue usrVal = new SPFieldUserValue(web,list.Items[0]["Created By"].ToString());
usrVal.LookupId;  // UserID
