How to Manually Drop Down the ComboBoxBase?


The dropdown area of ComboBoxBase can be programmatically displayed using the following code.

In this example, a button control is added to the form and a Click event handler is setup to call the DroppedDown property.


private void button1_Click(object sender, System.EventArgs e)


this.comboBoxBase1.DroppedDown =true;



Private Sub button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)

Me.comboBoxBase1.DroppedDown = True

End Sub
