我有一个用户控件,它的 DateTimePicker 覆盖了单行文本框 (Tb)
,覆盖了 DateTimePicker 的文本部分。文本框 Tb(绿色)被锚定(LTRB)。
调整用户控件的大小时会出现问题。
覆盖的日期时间选择器显示在文本 Tb 后面。
当前用户控件为 242(W) x 20(H) 。将控件的大小调整为低于 100 (Width) 时会出现问题。
我尝试了将 CustomFormat 设置为“”的空白文本,但用户控件支持许多 datetimepicker 功能,因此这不是一个选项。
我试图在用户控件上设置最小尺寸,但这也不起作用。
编辑:
该控件已在少数应用程序中使用。在这些应用程序中,控件的最小尺寸为 90X20,而我们现在设置的最小尺寸为 97x20。
进行更改后,VS Designer 会将现有控件的大小调整为 97x20 吗?
如何实现这种效果(重新调整为 97x20)?

编辑:添加最小尺寸后,它看起来更好,但当控件调整为最小尺寸并重建项目时,日历下拉菜单消失。
此外,文本框不会保持锚定在日历按钮附近。
编辑:为上面添加的图片..日历消失了。
编辑:哦,我又错过了一件事,日期字段和时间字段都是可折叠的。这就是拆分容器存在的原因。最小尺寸计算也必须意识到这一点。(我猜 2 个不同的最小尺寸取决于时间场的可见性。)
问题:
a)如何防止用户控件调整大小超过某个最小限制以避免上述问题?(pic1 似乎是想法大小)
b)我可以绘制 datetimepicker 使得文本被空白并且我们只看到
日历下拉按钮吗?如果是这样,我还需要处理调整大小事件吗?
c) 我怎样才能不断调整文本框的大小,使其始终覆盖 DTP 的日期文本部分。
