Create a winform program and drag a tabcontrol (delete two default tabpages in the tabpages attribute) and three buttons (add, delete, and modify)

  1. Public partial class form1: Form
  2. {
  3. Private int Index = 0;
  4. Public form1 ()
  5. {
  6. Initializecomponent ();
  7. }
  8. Private void form1_load (Object sender, eventargs E)
  9. {
  10. // This. tabcontrol1.selectedindex = 1;
  11. }
  12. Private void btnadd_click (Object sender, eventargs E)
  13. {
  14. Tabpage page = new tabpage ();
  15. Page. Name = "page" + index. tostring ();
  16. Page. Text = "tabpage" + index. tostring ();
  17. Page. tabindex = index;
  18. This. tabcontrol1.controls. Add (PAGE );
  19.  
  20. # Region three methods to set a tab as the current tab
  21. // This. tabcontrol1.selectedindex = index;
  22. This. tabcontrol1.selectedtab = page;
  23. // This. tabcontrol1.selecttab ("page" + index. tostring ());
  24. # Endregion
  25. Index ++;
  26. }
  27. Private void btnremove_click (Object sender, eventargs E)
  28. {
  29. Bool first = true;
  30. If (index> 0)
  31. {
  32. # Region two ways to delete a tab
  33. This. tabcontrol1.controls. removeat (this. tabcontrol1.selectedindex );
  34. // This. tabcontrol1.controls. Remove (this. tabcontrol1.tabpages [This. tabcontrol1.tabpages. Count-1]);
  35. # Endregion
  36. }
  37. Else
  38. {
  39. Return;
  40. }
  41.  
  42. # Region is used to delete the last tabpage and set the last and second to the current tab.
  43. If (first)
  44. {
  45. This. tabcontrol1.selectedindex = -- index-1;
  46. First = false;
  47. }
  48. Else
  49. {
  50. This. tabcontrol1.selectedindex = index --;
  51. }
  52. # Endregion
  53. }
  54. Private void btnupdate_click (Object sender, eventargs E)
  55. {
  56. This. tabcontrol1.selectedtab. Text = "xyt"; // modify the attributes of the current tab.
  57. // This. tabcontrol1.selectedtab. Name = "";
  58. // This. tabcontrol1.selectedtab. Tag = "";
  59. // This. tabcontrol1.selectedtab. Select ();
  60. }
  61. }
