is a control that displays a collection of items. More than one item in a ListBox is visible at a time. You can either populate the ListBox control directly, or bind it to a collection of items.
In this tutorial, i will discuss some events in ListBox such as adding and removing an item in a ListBox.
So, now let's start this tutorial!
1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to File
, click New Project
, and choose Windows Application
2. Next, add one TextBox named TextBox1
which will be used as an input for inputting the names of a school. Add one ListBox
named ListBox1 which will be used as a container to display the inputted schools in TextBox1. Add also two Buttons named Button1
" for adding items in the ComboBox and Button2
" for removing the selected item in the ListBox. You must design your layout like this:
3. Now, put this code in Button1_Click. This will trigger to add an item on the ListBox as we input a school in TextBox.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
For adding an item in the ListBox, we simply type this syntax
. The ListBox provides features that enable you to efficiently add items to the ListBox as we input a school on our TextBox. Then it will display the inputted string in our ListBox.
4. Now add this code for Button2_Click. This will remove the item you have selected in the ListBox. Note that you must put first your cursor in your selected item in the ListBox.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
For removing an item in the ListBox, we simply type this syntax
. The ListBox1.SelectedItem
here was an action to select or click an item in the ComboBox before clicking the remove button.
Then it will clear the your TextBox.
