In the ExpenseForm, when the expenseID is set, you can get the actual expense
by using the “Get” method of the Expenses object
■ Expense e = budget.Expenses.Get(expenseID);
Once you have the expense, you can use its properties to fill in the textboxes,
and date, etc.
The expense “category” property is the category ID, so to get the category object,
so you can use the “Get” method of the Categories object
■ Category c = budget.categories.Get(e.Category)
The selectectedItem of the ComboBox can be set directly. (No looping required)

Step 6 - Add the Modify/Delete Functionality to “Modify”
ExpenseForm (10%)

Add the functionality to the Modify and Delete button. After modifying or deleting the
expense, close the window. In main window, don’t forget to update the datagrid, and set
the appropriate controls (see assignment 4 for details if you have forgotten)
Hints:
○ To delete an expense from the budget, use the Delete property of the expenses
object
○ To modify an expense from the budget, use the Modify property of the expenses
object

EXTRAS - Optional… choose which ones you want to do, or do
something different. (25%)
Wow me! 25%
Impress me: 20%
Pretty Darn Good: 15%
Made an Effort: 10%
Ideas:
● Add some icons to the menu items
● Add Style to ToolBar Images so that they look greyed out when not enabled
● For the “Add” ExpenseForm, keep track of the date that was selected, so that if the user
chooses a different date, when they go back to the form, it was the last date they
selected
● Use method (main window) “ResetFocusAfterUpdate” to set the selected item in the
datagrid to be the last one modified, or to the one below what was just deleted

Add a double click event to the datagrid which then shows the “Modify” ExpenseForm
Add a context menu with “Modify/Delete/Cancel” on the datagrid. Only enable
“Modify/Delete” options if the datagrid is showing the standard view. See WPF tutorial
on context menus
Use “commands” to enable short-cut keys for all menus/toolbars etc”
