CreateObjRef Type. Inherited from MarshalByRefObject. Dispose Boolean. Equals Object. Determines whether the specified object is equal to the current object. Inherited from Object. Serves as the default hash function. GetService Type. Obtains a lifetime service object to control the lifetime policy for this instance. MemberwiseClone Boolean.
OnHelpRequest EventArgs. Resets all options, the last selected printer, and the page settings to their default values. RunDialog IntPtr. When overridden in a derived class, specifies a common dialog box. Runs a common dialog box with a default owner. ShowDialog IWin32Window. Runs a common dialog box with the specified owner. Occurs when the user clicks the Help button on a common dialog box.
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. When working with windows form, you can add events to controls. An event is something that happens when an action is performed. Probably the most common action is the clicking of a button on a form. In C Windows Forms, you can add code which can be used to perform certain actions when a button is pressed on the form. The below example will showcase an event for the Listbox control.
So whenever an item is selected in the listbox control, a message box should pop up which shows the item selected. Step 1 Double click on the Listbox in the form designer. By doing this, Visual Studio will automatically open up the code file for the form. And it will automatically add an event method to the code. This event method will be triggered, whenever any item in the listbox is selected.
Above is the snippet of code which is automatically added by Visual Studio, when you double-click the List box control on the form. One you make the above changes, and run the program in Visual Studio you will see the following output. From the output, you can see that when any item from the list box is selected, a message box will pops up.
