Create two panels in your form, a notification panel docked to top, and below that a content panel anchored to top. In your Form.Load, set the height of the notification panel to zero. Don't set the height to zero in Design View, you won't be able to click on the notification panel to edit it.

Then when you get a notification, draw the contents in the notification panel and create a System.Windows.Form.Timer that increases the height of the notification panel by a few pixels every few dozen milliseconds or so. Stop when the panel is of the desired height. Do the same with a negative height to hide the panel.

This does not require repainting or recalculating sizes or positions of anything, does not overdraw anything, and looks slick. I have done this and it works.

You could simply animate a panel dropping down from the top of the client area of the form.

Increasing the y coordinate of the panel in a timed loop. The panel would start invisible and slowly become visible. (The panel would start at -panel.height and work its way down to 0.)

blocks|key|3134255|text|如果您希望将其限制到特定的表单，那么在表单上放置一个Panel并将其Dock设置为DockStyle.Top，然后放置一个描述标签和一个隐藏该描述的按钮，这应该是非常简单的。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3134256|entityMap^0|Q|5|Y|4|15|D|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|O|8|@]|D|@]|E|$]]]|G|$]]

If you want it constrained to a particular form, it should be easy enough to put a <code>Panel</code> on the form with its <code>Dock</code> set to <code>DockStyle.Top</code>, then place a label for the description and a button that hides it.

blocks|key|3134367|text|使用面板或UserControl并不难，但最麻烦的部分是让表单的内容随着栏的滑下而滑下。为了简化这一点，我将使用SplitContainer。顶部拆分面板包含通知栏，拆分器距离最初为0。通过递增SplitterDistance属性将该条滑动到视图中。这样做意味着你不必担心使表单的其他内容滑下(这是一个麻烦，因为它阻止你使用停靠)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3134368|我能想到的使用SplitContainer的唯一缺点是，条形图的动画将略有不同:文本不会随着条形图向下滚动，而是在条形图向下滑动时显示在适当的位置。如果这让你困扰，你可以通过增加拆分器距离(只多几行代码)让文本(或者你的面板/自定义控件)滑下来解决这个问题。|3134369|显示栏：|3134370|++++for+(int+i+=+0;+i+<=+33;+i%2B%2B)

It's not difficult to do with a panel or a UserControl, but the fiddly part is making the contents of the form slide down as the bar slides down. To simplify that I would use a SplitContainer. The top splitpanel contains the notification bar and the splitter distance is initially 0. Slide the bar into view by incrementing the SplitterDistance property. Doing it this way means you don't have to worry about making the other contents of the form slide down (which is a hassle because it prevents you from using docking).

The only downside to using SplitContainer I can think of is that the animation of the bar will be slightly different: the text won't scroll down with the bar, it will be revealed in place as the bar slides down. If this bothers you, you can fix it by having the text (or your panel/custom control) slide down as you increase the splitter distance (only a couple more lines of code).

Showing the bar:

<pre><code> for (int i = 0; i &lt;= 33; i++)
 {
 splitContainer1.SplitterDistance = i;
 Thread.Sleep(5);
 Refresh();
 }
</code></pre>

Hiding the bar:

<pre><code> for (int i = 33; i &gt;= 0; i--)
 {
 splitContainer1.SplitterDistance = i;
 Thread.Sleep(5);
 Refresh();
 }
</code></pre>

Of course, if you don't mind the notification bar simply covering the top part of your form, then you can just do the whole thing very easily with a panel. :)

blocks|key|1130463|text|我刚才也在找同样的东西，找到了this+on+code+project|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1130464|我还没有用过它，所以我不知道它有多坚固。|1130465|entityMap|0|LINK|mutability|MUTABLE|url|http://www.codeproject.com/KB/miscctrl/InformationBar.aspx^0|F|K|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

I was looking for the same thing just now and found <a href="http://www.codeproject.com/KB/miscctrl/InformationBar.aspx" rel="nofollow">this on code project</a>

I have not used it yet, So I have no idea how solid it is.

You all know the "You've got new answers!" notification bar on SO. I'd like the same thing in a Form, preferably just as smooth. Is there a simple way? Or do I have to completely create this myself?

My searches did not yield any good results, only lots of progress bars and popups in the system notification area, but that's not what I'm looking for.

The messages I want to display belong to a Form, not to the whole application

How should I display a notification bar in WinForms?

你们都知道“你们有了新的答案！”SO上的通知栏。我希望同样的东西以一种形式出现，最好是一样平滑。有没有简单的方法？或者我必须完全自己创建这个？我的搜索没有得到任何好的结果，只有在系统通知区域有很多进度条和弹出窗口，但这不是我要找的。我要显示的消息属于一个表单，而不是整个应用程序
