my head stuck in the computer: C# Displays Follow On for ExpenseIt Showing Use of Panels

C# Displays Follow On for ExpenseIt Showing Use of Panels

This post will show my attempt at doing a navigation bar with the ExpenseIt non WPF (Windows Presentation Foundation) application example of Microsoft as I implemented using only one Windows Form and C# with the Microsoft Access database provided to avoid the need for canned data and panels rather than multiple forms. (See the previous post “C# Displays Follow On for ExpenseIt Showing Version of Navigation Bar”.)

Using panels rather than multiple forms means that everything runs within the one Windows form class. And mostly only the panel needs to be hidden or displayed rather than many different controls.

I used a separate panel for the arrow buttons at the top of the form and below it a set of different panels for the menu and the options that can be selected from the menu. I named them the NavigationPanel, the MenuPanel, AddEmployeesPanel, UpdateEmployeesPanel, EnterExpensesPanel, and the DisplayExpensesPanel plus the ListPanel to select an employee to Update, or enter or display their expenses.

This drastically cut the amount of code while making it more difficult to design panels rather than forms. That is, as panels were added, using the C# Toolbox to select controls into a particular panel got very difficult. A particular panel couldn't be selected so the controls of various panels would all be displayed in the Form1.cs[Design] window intermixed with each other.

Starting out I had searched the internet and the answers all seemed to be that the controls would have to be created at runtime rather than via the C# Form1.cs[Design] window using the Toolbox. I checked what I had done with the Display application of a number of years ago and found that I had done an interface class where I had used a Container control as the parent for the panel control. I had used a Config(uration) class where I kept the structure of the various Containers with the various controls of the each container with their size, location, etc. In each case the panel was the immediate child control of the Container control. When the messages between the Display application and the Ada framework applications signaled that a change was necessary, a lookup was done to locate the new container in the configuration and its controls were created at runtime. So I was doing what the internet search results suggested and what I should have remembered.

But I didn't want to repeat this technique for the limited number of panels that were going to be necessary for the ExpenseIt application. And I found that it wasn't necessary.

One online response did suggest the use of "this.Controls.Add(thePanel)" while others replied on the same site that the panel controls would need to be added programmatically as I had previously done. Instead all that was necessary was to add a statement such as

Controls.Add(AddEmployeesPanel);

to the button event handler that selects the panel. Then the controls of the panel displayed after adding

AddEmployeePanel.Visible = true;

That is, after the Form1.cs[Design] was used to select a panel into the window and changing the new panel's name to AddEmployeesPanel.

I had created the NavigationPanel and the MenuPanel first. And then it got more complicated due to the controls getting mixed up with those of multiple panels showing all together.

In this case, after all done creating the panels, the Navigation Panel is at the top, the MenuPanel is displayed along with the final DisplayExpensesPanel and some of the controls of other panels with the Add button of the AddEmployee Panel visible and other text boxes, a portion of a label showing from behind the Menu Select button, etc.

After doing the MenuPanel and the panel to add an employee I gave it an initial try just to see what would happen when switching the panel to be displayed. Upon the button click to display the panel to add an employee, the menu panel was hidden as expected but the AddEmployees Panel was blank. That's when I found out about the

Controls.Add(AddEmployeesPanel);

command and the need to also use

AddEmployeesPanel.Visible = true;

This combination caused the newly selected panel to be displayed.

In adding the AddEmployeesPanel I found out that for some reason I had to move it down. That is, the y location had to be lower than that of the Menu panel. As I went along I also found that I needed to rename controls that were going to need to be referenced by the code, resize if necessary, and double click a button control, for instance, to get its event handler method added to Form1 while the panel was available in the [Design] window. This was because it could be difficult to find the panel in the jumble to do it later.

For instance, when I finished I found that the Display Expenses panel had a small textbox in the middle of the Last Name textbox. But I was unable to get the panel to display in the [Design] window to delete it. However, I found that I could edit the Form1.Designer.cs file and locate a textbox within the code for the DisplayExpensesPanel that had its original name. So I deleted that line of code and the panel then displayed correctly. With this success I also adjusted the size and location of the panels to be similar making the display of the panels more consistent.

As I added panels I looked for ways that I could copy a Toolbar control into the correct panel. At times I could move the newly created panel somewhat off to the side so that controls be would placed within it and then move the panel back. Although this became more difficult to accomplish as more panels were added. So at times, when executing the application to check on the looks of the panel, I would find that the control had been added to the wrong panel. So I would have to delete it and try again. I did find that at times a right click on a panel and selecting

Send To Back could be helpful as the desired panel might rise to the top. And sometimes a list of panels would show up after the right click, but not all the panels would be listed. Also Send To Back frequently didn't eventually bring the desired panel to the top. So it was a learning experience.

Selection of the Enter Expenses panel first displays the List Panel to allow the desired employee to be chosen. Note: The title is changed on the List Panel depending upon the Menu Panel selection. The Enter button does some validation of the entered data and then updates the Expenses Database. An error will be displayed in the lower text box.

Selection of Display Expenses is similar in that the List Panel will be displayed first. The ListPanel is used for ShowList or if the Enter Expenses or Display Expenses panels are selected. The version shown is when Enter Expenses has been selected. The Cancel button returns to the parent panel.

The illustrated UpdateEmployee panel is the initial view after the selection of John Bull from the employee list as displayed using the ShowList button. This panel has some variations. If Modify is clicked, these buttons will be hidden and a Department label and textbox will be displayed so that the employee's department can be changed. An Update button and an error message text box will also appear to indicate that change is to be applied to the Employee Database while an error can appear if the employee is changed incorrectly or a text box is left blank.

In using Display Expenses it occurred to me that I could add a Next button in the same location as Enter button on the Enter Expenses panel to redisplay the List for the selection of another employee. Currently, the operator has to return to the Menu and reselect Display Expenses. However, I didn't want to mess up the panels so I left the panel unchanged. It has occurred to me that in observing the structure of the compiler generated Form1.Designer.cs file that it might be possible to edit it to add such controls (taking care to first save the file in case it has to be restored).

Code Organization

The event handlers are all assigned to Form1.cs. This somewhat works against object oriented since there really isn't a panel object. That is, although there is panel in the [Design] Toolbox organized under a Containers heading, it doesn't carry over into C#. Everything is directly a part of Form1.

So since all the controls are under the Windows Form rather than their particular panel I have grouped the button click event handlers and other methods within the Form1.cs file by the panel that should have been their container.

For the organization of the code I added a Navigation class to go with the previous SelectionQueue class and the new Form1 class.

The SelectionQueue class continues to keep track of which panels have been selected in the order of the original selection (except, of course, for the Navigation Panel). This allows it to return whether a left or right arrow (or both) should be active depending upon whether the current panel is the last one queued, the first one queued, or in the middle. Note: The displayed Menu Panel has had another panel chosen after it, such as the displayed Add Employees panel, so there is an active right arrow.

The Navigation class is also involved in the changing of the panels and the use of the arrow buttons.

The Form1 class is arranged in sections. After the static variables and the constructor, comes the code associated with the Navigation Panel including the event handlers to forward the arrow clicks. Then there is a structure that encapsulates data by the PanelSelection enumerated type. For each enumerated panel the panel name is given, any parent or child panel and whether the panel is to be displayed before the child or parent. As I got further along with the code I found that I didn't need displayFirst but left it in. Then there is the SwitchPanels method that was placed here rather than in the Navigation class since it uses Form1 objects and the LoadEmployeeList method that is invoked from SwitchPanels.

Only a minimum number of lines of code are necessary to switch from one panel to another. In some cases, such as Menu and Add Employee, only two lines of code are needed to add the panel control and make the panel visible (after the previous panel was hidden in the entry code). This code was placed in the SwitchPanels method to avoid needing to do it twice – once if a button was clicked such as on the Menu Panel and once if an arrow button was clicked on the Navigation Panel.

Then, the event handlers are coded arranged according to their panel. Each of these normally has only to invoke SelectPanel of the Navigation class. Other times the panel isn't changed, such as AddEnteredEmployee_Click where textboxes have to be read, one of the databases accessed, a possible error message displayed, etc so all the code is within the event handler.
