我的获胜形式有组合框。当我第一次点击它。它自动关闭,之后我可以打开它并选择一个项目! 这对我来说是意外的!!
这是我的代码:
Private Sub cmbType_Enter(sender As System.Object, e As System.EventArgs) Handles cmbType.Enter
cmbType.DroppedDown = True
End Sub
Private Sub cmbType_Leave(sender As System.Object, e As System.EventArgs) Handles cmbType.Leave
cmbType.DroppedDown = False
cmbType.BackColor = Color.White
End Sub
任何人都可以帮助我吗?

通过选择SelectedIndexChanged事件来使用此代码: if(!comboBox1.DroppedDown)comboBox1.DroppedDown = true;
