Overview of Topics

• Single Document Interface (SDI)

• Multiple Document Interface (MDI)

• ToolStrip Control

• Calendar Controls

Multiple Document Interface (MDI)

• Multiple forms are displayed within the same window.
• Parent form (main window) "contains" other forms.
• Many Child forms (document windows) can be

"contained within" Parent window.

• Parent and Child may share menus, toolbars, etc.
• Should add a Window menu option that allows users:
  • To switch between opened documents.
  • Display documents as Tile Vertically, Tile Horizontally or Cascade.

MDI Example

Windows Menu Option

• Allows the user to arrange multiple Child forms.
• Allows the user to switch between documents.
• To list opened Child documents
  • Create a Windows menu item (mnuWindows)
  • On the menuStrip, set MdiWindowListItem property to the Windows menu item name (mnuWindows).
  • This will list the child documents automatically.

LayoutMdi Method

• Use the LayoutMdi method to set the type of layout:

this. LayoutMdi ( MdiLayout .TileHorizontal);

this. LayoutMdi ( MdiLayout .TileVertical);

this. LayoutMdi ( MdiLayout .Cascade);

private void mnuWindowTileHortzonal_Click(object sender, EventArgs e) { this.LayoutMdi(MdiLayout.TileHorizontal); }

ToolStrip Control

• Place the ToolStrip control on the form.
• Click on the Add ToolStripButton to get a dropdown list of options.
• Select the first one, Button to add a button to the toolStrip.
• Click on a button to select it, and then set the properties for it, including the Name (tbbChild1), Image, and Text. Text becomes the tool tip.

Coding for ToolStrip Buttons

• Each button on the toolStrip has its own ButtonClick event.
• Double click on the button to create the default method and enter the required code.

private void tbbChild1_Click(object sender, EventArgs e)

ChildForm1 frmChild1 = new ChildForm1( );

frmChild1.MdiParent = this;

frmChild1.Show();

Calendar Control

• Provides the ability to display calendars on a form.
• DateTimePicker
  • Displays only day and date unless user drops down the calendar.
  • Value property contains date.
• MonthCalendar
  • Displays entire month as a calendar.
  • Stores a date range, so values are stored in SelectionRange.Start and SelectionRange.End
• Event triggered when value or date is changed.
