Occurs when the user changes the selected item and that change is displayed in the ComboBox.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The event is raised only when the user changes the combo box selection, and you can create a handler for this event to provide special handling for the ComboBox when the user changes the selected item in the list. However, depending on how the ComboBox is configured, and how the user changes the selected item, the event may not be raised. Alternatively, you can handle the SelectedIndexChanged, but note that this event occurs whether the index is changed programmatically or by the user.
For more information about handling events, see Handling and Raising Events.
The following code example uses the event and the SelectionLength property to change the length of the text box depending on what the user has selected and committed.
Private Sub comboBox1_SelectionChangeCommitted(ByVal sender _ As Object, ByVal e As EventArgs) _ Handles comboBox1.SelectionChangeCommitted Dim senderComboBox As ComboBox = CType(sender, ComboBox) ' Change the length of the text box depending on what the user has ' selected and committed using the SelectionLength property. If (senderComboBox.SelectionLength > 0) Then textbox1.Width = _ senderComboBox.SelectedItem.ToString().Length() * _ CType(Me.textbox1.Font.SizeInPoints, Integer) textbox1.Text = senderComboBox.SelectedItem.ToString() End If End Sub
