Add txtCountry. Text ; Also, once an item is added, for a better user experience, it is advisable to clear the text box so a user can type in a new value with ease. Clear ;. Add txtState. Text ; txtState. Clear ; For the "Remove Country" and "Remove State" buttons, you follow a similar approach as the Items collection, but this time instead of "Add " you call the "Remove " method, and as you know, the prerequisites for an item removal is that an item must be selected first either in the ListBox or the ComboBox.
Hence, the code seeks a SelectedItem to be passed to the Remove method. Remove lstCountry. SelectedItem ; cboState. Remove cboState. SelectedItem ; Now for the "Show Details" button, you have used some conditional logic to produce a different message based on your selection, specifically with the Male and Female radio buttons. The CheckBox and RadioButton controls offer a property named Checked, that can be either true or false, that is, checked or not checked.
You build a condition around these and then show a message box. View All. Vidya Vrat Agarwal Updated date Aug 08, User Interface Design Principles The best mechanism for interacting with any application is often a user interface. Best Practices for User Interface Design The user interface provides a mechanism for users to interact with your application. Simplicity Simplicity is an important aspect of a user interface.
Position of Controls The location of controls on your user interface should reflect their relative importance and frequency of use. Consistency Your user interface should exhibit a consistent design across each form in your application. Aesthetics Whenever possible, a user interface should be inviting and pleasant. Color Judicious use of color helps make your user interface attractive to the target audience and inviting to use.
Fonts Usability should determine the fonts you choose for your application. Images and Icons Pictures and icons add visual interest to your application, but careful design is essential to their use. Sorting Properties in the Properties Window Each object such as a form control has many properties you may need to set while working with an application. Categorized View The Categorized View organizes properties in the form of sets of properties, and each set has a name to describe that collection of properties; for example, there are categories named Appearance, Behavior, Data, Design, Focus, and so on.
Categorized View of properties Alphabetical View The Alphabetical View organizes properties in ascending order by name from a to z. Alphabetical View of properties Setting the Properties of Solutions, Projects, and Windows Forms forms Before you begin putting controls onto the Windows Forms form, you need to learn how to modify some property values of the solution, project, and form you created earlier shown previously in Figure IDE after setting the properties for your solution, project, and Windows Forms form Working with Controls Now that you have your Windows Forms application in place, you can start working with the controls.
Go to the project named WinApp located under the solution, that you created earlier refer to Figure Ensure that you are in the Design View. Drag a Label control onto the form, and position it at the top middle of the form. Select this label, navigate to the Properties window, and set the following properties: Set the Name property to lblWelcome. Set the Text property to Welcome. Select the Font property, click the ellipsis button, and specify the size of the Label control as 16 points in the Size drop-down list.
Set the TextAlign property to TopCenter. Drag two more Label controls onto the form, and put them below the "Welcome" text, a little toward the left of the form. Select the first label, navigate to the Properties window, and set the Name property to lblFirstName and the Text property to First Name.
Now select the second label, navigate to the Properties window, and set its Name property to lblLastName and its Text property to Last Name. Select textBox1, go to the Properties window, and set its Name property to txtFname.
Select textBox2, and in the Properties window set its Name property to txtLname. Drag a Button control onto the form, and place it below the Label and TextBox controls. Select the Button control, go to the Properties window, change the Name property to btnSubmit, and then set its Text property to Submit.
Now you have your GUI design of the application ready; it should resemble the form shown in Figure Now let's add the following code inside this btnSubmitClick event to do the desired functionality of a dialog, with a message, a caption in the dialog box's title bar, an OK button, a Cancel button, and an information icon displayed: MessageBox.
Information ; Now your Code View will show the button's click event code, as shown in Figure To provide the functionality for this control, you add the following code: MessageBox. Information ; "MessageBox. Dock Property The Dock property allows you to attach a control to one of the edges of its parent. Setting the Dock property Anchor Property When a user resizes a form, the controls maintain a constant distance from the edges of their parent form using the Anchor property.
Go to Solution Explorer and open the WinApp project. Open the WinApp form in the Design View. Select the form by clicking its title bar; you will see handles around the form's border, that allow you to resize the form's height and width.
Place the cursor on the handle of the right border, and when the mouse pointer becomes double-headed, click and stretch the form toward the right side. You will see that the form's width increases, but the controls are still attached to the left corner of the form.
Similarly, grab the handle located on the bottom of the form and try to increase the height of the form. You will notice that the controls are still attached to the top side of the form.
Have a look at Figure , that shows a resized height and width form and the position of the controls. The controls appear in the top-left corner because their Dock property values are None and their Anchor property values are Top, Left. Resized form and position of controls Now you will try to set the Dock and Anchor properties for the controls and then retest the application.
Select the Label control named lbl Welcome, and set the Text value to Welcome. Go to the Properties window. Select the AutoSize property, and set its value to False default value is True. Resize the width of the Label control to the width of the form, and adjust the Label control to the top border of the form. Set this control's TextAlign property to Top, Center. Set the Dock property for the Label control from None to Top, that means you want the label to always be affixed with the top border of the form.
Now select all the remaining controls two Labels, two TextBoxes, and one Button either by scrolling over all of them while holding down the left mouse button or by selecting each with a click while pressing down either the Shift or Ctrl key. Once you have selected all the controls, go to the Properties window. You will see listed all the properties common to the controls you have selected on the form. This will allow you to adjust the controls accordingly as soon as you resize the form.
The controls will also grow in size accordingly to adjust to the width of the form, as you can see in Figure The effect of the Anchor property setting Top, Left, Right on a resized form Note: The Anchor property has very interesting behaviors; you can try setting this property in various combinations and see the effects when you resize your form.
Return the form to its previous size so you can see the effects of setting another Anchor property. Select all the controls again as you did in step 8.
Set the Anchor property to Top only and try resizing the form now. You will notice that the controls are floating in the middle of the form when you resize it, as you can see in Figure The effect of the Anchor property setting Top on a resized form Save the changes in your project by clicking "File" "Save All". How It Works When you resize the form, it will behave according to the settings of the Dock and Anchor properties.
This will add a new Windows Forms form to your project. In the Add New Item dialog box displayed, change the form's name from "Form1. Click "Add".
The new form with the name "UserInfo" will be added to your project. Ensure that the newly added form "UserInfo" is open in the Design View. Step 2 Once the label has been added, go to the properties window by clicking on the label control. In the properties window, go to the Text property of each label control.
A textbox is used for allowing a user to enter some text on the Windows application in C. We will add 2 textboxes to the form, one for the Name and the other for the address to be entered for the user. Step 1 The first step is to drag the textbox control onto the Windows Form from the toolbox as shown below. Step 2 Once the text boxes have been added, go to the properties window by clicking on the textbox control. In the properties window, go to the Name property and add a meaningful name to each textbox.
For example, name the textbox for the user as txtName and that for the address as txtAddress. A naming convention and standard should be made for controls because it becomes easier to add extra functionality to these controls, which we will see later on.
A Listbox is used to showcase a list of items on the Windows form. We will add a list box to the form to store some city locations. Step 1 The first step is to drag the list box control onto the Windows Form from the toolbox as shown below.
Step 2 Once the list box has been added, go to the properties window by clicking on the list box control. In the output, you can see that the Listbox was added to the form. You can also see that the list box has been populated with the city values. A Radiobutton is used to showcase a list of items out of which the user can choose one.
Step 2 Once the Radiobutton has been added, go to the properties window by clicking on the Radiobutton control. A checkbox is used to provide a list of options in which the user can choose multiple choices. We will add 2 checkboxes to our Windows forms. These checkboxes will provide an option to the user on whether they want to learn C or ASP. Step 1 The first step is to drag the checkbox control onto the Windows Form from the toolbox as shown below. Step 2 Once the checkbox has been added, go to the properties window by clicking on the Checkbox control.
A button is used to allow the user to click on a button which would then start the processing of the form. Step 1 The first step is to drag the button control onto the Windows Form from the toolbox as shown below. Step 2 Once the Button has been added, go to the properties window by clicking on the Button control. Congrats, you now have your first basic Windows Form in place. Next, select C from the Language list, and then select Windows from the Platform list. Next, in the Visual Studio Installer, select the.
After that, select the Modify button in the Visual Studio Installer. Next, select Continue to install the workload. Then, select Create. After you select your C project template and name your file, Visual Studio opens a form for you. A form is a Windows user interface. We'll create a "Hello World" application by adding controls to the form, and then we'll run the app.
If you don't see the Toolbox fly-out option, you can open it from the menu bar. In the Properties window, locate Text , change the name from button1 to Click this , and then press Enter. If you don't see the Properties window, you can open it from the menu bar. Or, press F4. In the Design section of the Properties window, change the name from button1 to btnClickThis , and then press Enter.
If you've alphabetized the list in the Properties window, button1 appears in the DataBindings section, instead. Now that we've added a button control to create an action, let's add a label control to send text to. Select the Label control from the Toolbox window, and then drag it onto the form and drop it beneath the Click this button.
In either the Design section or the DataBindings section of the Properties window, change the name of label1 to lblHelloWorld , and then press Enter. In the Form1. Alternatively, you can expand Form1.
Several things will happen. But outside of the IDE, a Form1 dialog box appears. WinForms applications can contain the different type of controls like labels, list boxes, tooltip etc.
Click on Windows Forms App. NET Framework in the middle of current window. After that give the project name and Click OK. Here the solution is like a container which contains the projects and files that may be required by the program.
After that following window will display which will be divided into three parts as follows: Editor Window or Main Window: Here, you will work with forms and code editing. You can notice the layout of form which is now blank. You will double click the form then it will open the code for that. Solution Explorer Window: It is used to navigate between all items in solution.
For example, if you will select a file form this window then particular information will be display in the property window. Properties Window: This window is used to change the different properties of the selected item in the Solution Explorer.
Also, you can change the properties of components or controls that you will add to the forms.
