  14. Add another new Browse Screen

  43. Screen Data: MenuTile
  44. Additional Data: Details
  45. Lets first add a button to the Command Bar
  46. Write our own method, DeleteSelectedTile
  47. Add the following code into the method
    	// Setup a dialog box to verify ok to delete
    	msls.showMessageBox("Are you sure you want to delete the \nMenu Tile, including all associated data?", {
    		title: "Delete Menu Tile",
    		buttons: msls.MessageBoxButtons.yesNo
    	}).then(function (e) {
    		if (e == msls.MessageBoxResult.yes) {
  48. Back in MenuTileAddEdit screen
  49. Delete the Menu Details Model Picker field
  50. Delete the Permission Id field, not the Permission Modal Picker
  51. Change the following to Custom Controls
    Tile Color
    Status Bg Color
    Status Fg Color
    Badge Bg Color
    Badge Fg Color
    Icon Bg Color
    Icon Fg Color

  52. Now here is how we’ve laid out our screen, adjust yours to your liking
    Menu tile add edit

  53. Expand your Icon Details Modal Picker
  54. Change the Icon Summary to a Columns Layout
  55. In Properties change the Columns Layout Width to Stretch to Container
  56. Delete all the fields but Name

  59. Full Path should show: MenuTile.Icon(item)
  60. Move the Custom Control ahead of the Name field
  61. Expand the control, delete all the fields
  62. In Properties for the Control, change the Width to Fit To Content
  63. Then Edit Render Code for this Custom Control
  64. Add the following into the method
    	// call our helper function, easy!
    	itgLsHelper.iconPicker(element, contentItem);
  65. This would be a good time for you to drag the itgLsHelper.js to the top of the screen so you will have intellisense.
  66. Now the easy part, Edit Render Code for each of your Color Custom Controls
    Tile Color
    Status Bg Color
    Status Fg Color
    Badge Bg Color
    Badge Fg Color
    Icon Bg Color
    Icon Fg Color

  67. Add the following into each of the color methods
    	itgLsHelper.colorPicker(element, contentItem);
  68. Final piece, go to Write Code, created method of the screen
  69. Add the following code into the method
    			// Go get our OnClick field (contentItem)
    			var onClickContentItem = screen.findContentItem("OnClick");
    			// Update our screen picker with the list of screens
    			// This should be within screen created vs post render of the field
  70. Great! We are done with the MenuTileAddEdit screen!
  71. Back to the MenuView screen
  72. Add a new button to the Command Bar
  73. Exiting method, Menu, Edit

  78. Also for the Menu Tiles List in Properties, Item Tap
  79. Existing Method, showMenuTileAddEdit
  80. Data should be – MenuTile: MenuTiles.selectedItem
  81. Now for your DeleteEntireMenu button, add the following to its execute method
    	// Setup our dialog box to verify ok to delete
    	msls.showMessageBox("Are you sure you want to delete the entire \nMenu, including all associated tiles?", {
    		title: "Delete Entire Menu",
    		buttons: msls.MessageBoxButtons.yesNo
    	}).then(function (e) {
    		if (e == msls.MessageBoxResult.yes) {
    			// Delete and commit, returning us to the browse screen
  82. Back in the MenuView screen
  83. Edit PostRender Code for the Menu Tiles Tab
  84. Add the following code to add the Menu name to the header
    	// Bind so that changes will be reflected
    	contentItem.dataBind("screen.Menu.Name", function (newValue) {
    		contentItem.screen.details.displayName = newValue + " Menu Tiles";
