DateTimePicker & MonthCalendar

2. DateTimePicker & MonthCalendar

3. dateTimePicker1.Format = DateTimePickerFormat.Custom; dateTimePicker1.CustomFormat = "MMMM dd, yyyy - dddd"; Next Slide to see list Custom Format

7. ListBox privatevoid frmListBox_Load(objectsender, EventArgs e) {listBox1.Items.Clear(); for(int i = 0; i < 10; i++) listBox1.Items.Add("Item " + i); } privatevoidlistBox1_SelectedIndexChanged (object sender, EventArgs e) { lblMessage.Text= listBox1.Text +" was clicked!"; }

8. And We can use AddRangemethod to add data: privatevoidfrmListBox_Load(object sender, EventArgs e) { string[] strArr = newstring[] { "Tèo","Tí","Bin","Bo"}; listBox1.Items.AddRange(strArr); }

9. publicclassCStudent { privatestringm_strID; privatestringm_strName; publicCStudent(stringstrID, stringstrName) { this.m_strID = strID; this.m_strName = strName; } publicstring ID { get{ returnthis.m_strID; } set{ this.m_strID = value; } } publicstring Name { get{ returnthis.m_strName; } set{ this.m_strName = value; } } }

10. usingSystem.Collections; Also We can use DataSource to display data ArrayListarr = newArrayList(); for(inti=0;i<10;i++) {arr.Add(newCStudent("ID_"+i,"Name "+i)); } listBox1.DataSource = arr; listBox1.ValueMember = "ID"; listBox1.DisplayMember = "Name";

11. To get object from Listbox, We could use coding below: if(listBox1.SelectedItem != null) { CStudentsvTeo= (CStudent) listBox1.SelectedItem; lblMessage.Text= aStudent.Name + " Was selected"; }

12. CheckedListBox btnAdd btnAddAll chklbLeft chklbRight btnRemove btnRemoveAll

13. Use Items to add data privatevoidfrmCheckListBox_Load (object sender, EventArgs e) { chklbLeft.Items.Add("Tèo"); chklbLeft.Items.Add("Tí"); chklbLeft.Items.Add("Bin"); chklbLeft.Items.Add("Bo"); } Or we could use AddRange chklbLeft.Items.AddRange(new string[] { "Tèo","Tí","Bin","Bo"});

14. How to process Items Checked??? Case 1: CheckedListBox.CheckedIndexCollectionindexCollection = chklbLeft.CheckedIndices; stringstrChecked = ""; foreach(intiinindexCollection) { strChecked+= i + ";"; } MessageBox.Show(strChecked);

15. How to process Items Checked??? Case 2: CheckedListBox.CheckedItemCollectionitems = chklbLeft.CheckedItems; stringstrChecked= ""; foreach(string s in items) { strChecked+= s + ";"; } MessageBox.Show(strChecked);

16. How to process Items Checked??? Case 3: stringstrChecked= ""; for(int i = 0; i < chklbLeft.Items.Count; i++){ if(chklbLeft.GetItemChecked(i)) { //Process Item checked here } }

17. Go back ChecklistBox Example: privatevoidbtnAdd_Click (object sender, EventArgs e) { foreach(inti inchklbLeft.CheckedIndices) { chklbRight.Items.Add(chklbLeft.Items[i]); } foreach(string s inchklbRight.Items) {chklbLeft.Items.Remove(s);} }

18. privatevoidbtnAddAll_Click (object sender, EventArgs e) { chklbRight.Items.AddRange (chklbLeft.Items); chklbLeft.Items.Clear(); }

19. privatevoidbtnRemove_Click (object sender, EventArgs e) { foreach(string s inchklbRight.CheckedItems) chklbLeft.Items.Add(s); foreach(strings inchklbLeft.Items) chklbRight.Items.Remove(s); }

20. privatevoidbtnRemoveAll_Click (object sender, EventArgs e) { chklbLeft.Items.AddRange (chklbRight.Items); chklbRight.Items.Clear(); }

21. Menu (2 ways to use) MenuStrip MainMenu MenuItem ToolStripMenuItem Menu Property MainMenuStrip Property

22. I would like to tell you : using MainMenuis the basic Menu. In this case, I will demo add Menu at Runtime for you. Please see next slide !

23. Coding to create Menu at Runtime

24. privateMainMenumainMenuBar; privateMenuItemmenuFile, menuEdit, menuFileNew, menuFileOpen, menuFileExit, menuEditCut, menuEditCopy, menuEditPaste; privatevoidcreateMenu() { mainMenuBar= newMainMenu(); this.Menu= mainMenuBar; menuFile=newMenuItem("File"); menuFileNew= newMenuItem("New"); menuFileOpen= newMenuItem("Open"); menuFileExit= newMenuItem("Exit"); menuFile.MenuItems.Add(menuFileNew); menuFile.MenuItems.Add(menuFileOpen);

25. privatevoidcreateMenu(){…… • menuFile.MenuItems.Add("-"); • menuFile.MenuItems.Add(menuFileExit); • mainMenuBar.MenuItems.Add(menuFile); • menuEdit= newMenuItem("Edit"); • menuEditCut= newMenuItem("Cut"); • menuEditCopy= newMenuItem("Copy"); • menuEditPaste= newMenuItem("Paste"); • menuEdit.MenuItems.AddRange(newMenuItem[] { menuEditCut,menuEditCopy,menuEditPaste}); • mainMenuBar.MenuItems.Add(menuEdit); • attachEvents();}

26. private void attachEvents() { menuFileNew.Click += process_MenuClick; menuFileOpen.Click += process_MenuClick; menuFileExit.Click += process_MenuClick; menuEditCut.Click += process_MenuClick; menuEditCopy.Click += process_MenuClick; menuEditPaste.Click += process_MenuClick; }

27. privatevoidprocess_MenuClick (object sender, EventArgs e) { if(sender.Equals(menuFileExit)) { Application.Exit(); } } privatevoidfrmMenuBasic_Load (object sender, EventArgs e) {createMenu(); }

28. MenuStrip

29. Designer Click on button to add MenuItem

30. Click Add button to add new MenuItem Text to Display Click here to add Sub MenuItem MenuItem’s Name

38. MenuStrip At Runtime

39. privateMenuStripmenuBar; privateToolStripMenuItemmenuFile, menuEdit, menuFileNew, menuFileOpen, menuFileExit, menuEditCut, menuEditCopy, menuEditPaste;

40. privatevoidcreateMenu() {menuBar= newMenuStrip(); menuBar.Font= newFont("arial", 36, FontStyle.Bold, GraphicsUnit.Pixel); this.MainMenuStrip= menuBar; menuFile = newToolStripMenuItem("File"); menuFileNew= newToolStripMenuItem("New"); menuFileNew.Image= imageList1.Images[0];

41. menuFileOpen = newToolStripMenuItem("Open"); ToolStripSeparatorsp = newToolStripSeparator(); menuFileExit= newToolStripMenuItem("Exit"); menuFileExit.Image= imageList1.Images[1]; menuFile.DropDownItems.Add( menuFileNew); menuFile.DropDownItems.Add( menuFileOpen);

42. menuFile.DropDownItems.Add(sp); menuFile.DropDownItems.Add( menuFileExit); menuEdit= newToolStripMenuItem("Edit"); menuEditCut= newToolStripMenuItem("Cut"); menuEditCopy= newToolStripMenuItem("Copy"); menuEditPaste= newToolStripMenuItem("Paste");

43. menuEdit.DropDownItems.AddRange(newToolStripItem[] { menuEditCut,menuEditCopy, menuEditPaste}); menuBar.Items.AddRange(newToolStripItem[] { menuFile,menuEdit}); this.Controls.Add(menuBar); attachEvents(); } private void attachEvents() {menuFileExit.Click += processClick; }

44. privatevoidprocessClick (object o, EventArgs e) { if (o.Equals(menuFileExit)) Application.Exit(); } privatevoidfrmMenuStrip_Load (object sender, EventArgs e) { createMenu(); }

45. ContextMenuStrip Drag & Drop into the FORM
