当 dgv 隐藏时，DataGridView 滚动条消失（GUI /刷新问题）
我有一个表单应用程序，将多个 DataTable 的结果显示到多个 DataGridView 中，每个 DataGridView 出现在应用程序的不同选项卡中。
当我重新加载数据时，我注意到了奇怪的行为（一个按钮调用从匹配的 DT 中填充所有 DGV）：具有大量行（需要垂直滚动）的 DGV 未显示（仅显示一个，因为它们位于选项卡控件）在数据获取后没有滚动条。 但是窗口大小调整会显示滚动条...
我尝试在 dgv.DataSource = dt 之后在每个 DGV 上强制执行 dgv.Refresh() ，但没有运气。
任何意见将不胜感激。
干杯!
I have a forms application, showing results of several DataTables into several DataGridViews, each appearing in a different tab of an application.
I've noticed weird behavior when I reload the data (a single button invokes filling all DGVs from the matching DTs): DGVs with a lot of rows (which require vertical scrolling) which are not shown (only one is shown since they are in a tab control) don't have their scroll bars after the data fetch. But a window resize will show the scroll bars though...
I've tried forcing a dgv.Refresh() on each DGV after the dgv.DataSource = dt, but no luck.
Any input will be appreciated.
Cheers!

也许填充后会这样？
希望它有帮助，如果没有，你能告诉我们你是如何填充它们的吗？
谢谢。
Maybe this after populating it?
Hope it helps, if not, could you show us how you're populating them?
Thanks.
我的情况听起来和你的差不多。 我遇到了同样的问题，发现这是因为我在后台线程中禁用和启用选项卡。 一旦我将禁用和启用选项卡的调用移至主线程，滚动条就会正常运行。
My situation sounds pretty much identical to yours. I was having this same issue and found out it was because I was disabling and enabling the tabs in a background thread. Once I moved the calls to disable and enable the tabs to the main thread the scrollbars behaved normally.
我有一个稍微类似的问题，但这可能有助于激发您的想法。 对我来说，这似乎与我的控件的停靠方式有关。 我找到了一个相当复杂的解决方案，简而言之，就是添加一个新面板，然后将控件再次重新放置在该面板的顶部。 由于我发现在所有控件出现后重新调整表单大小会带回滚动条，因此我刚刚添加了 me.width = me.width+1 作为我的 form_load 事件的最后一条语句。
I have a slightly similar issue, but maybe this may help in sparking an idea for you. For me, it appears to be something to do with the way my controls are docked. I found a rather convoluted solution which in short, says to add a new panel, and re-position the controls again on top of that panel. Since i found that re-sizing the form after all my controls appears to bring back the scroll bars, I just added a me.width = me.width+1 as my last statement to my form_load event.
