in this video i'll show how to retrieve the Value of Selected item
from a ComboBox in C# Windows Forms applications and respond to user selections is a straightforward process.
To begin, we need to create a ComboBox control and populate it with the desired items.
For instance, let's consider a scenario where you've populated the ComboBox with various color options such as Red, White, Yellow, Black, Blue, Green, and Pink. After adding the items, you'll want to attach an event handler to the ComboBox's "SelectedIndexChanged" event. Within this event handler, we can access the selected item using the ComboBox's "SelectedItem" property.
Now let's go on and write a simple function to display a MessageBox indicating that their favorite color has been selected when the user picks a color from the ComboBox.
