[Drag and drop](https://www.mindstick.com/forum/454/how-to-drag-and-drop-multiple-image-from-one-canvas-to-onther-canvas-in-html5) ComboBox from toolbox on [window Form](https://www.mindstick.com/forum/527/how-to-pass-datagridview-s-cells-value-to-another-window-form).

## Code:

```
'Here Item is added in combobox on form loadPrivate Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load                 ComboBox1.Items.Add("C#")'Add the First item in ComboBox         ComboBox1.Items.Add("J#")         ComboBox1.Items.Add("VB")         ComboBox1.Items.Add("Java")     End Sub'Here show the selected item in Label2 on ComboBox SelectedIndexChanged event        Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)  Handles ComboBox1.SelectedIndexChanged         ' Assign the selected item in label         Label2.Text = "You selected " + ComboBox1.SelectedItem      End Sub
```

In above code Item is added dynamically so all Item in ComboBox1 will show at run time.
