blocks|key|1253221|text|将“工具提示”控件从工具箱拖到窗体上。除了名称之外，您实际上不需要为它提供任何属性。然后，在要显示工具提示的控件的属性中，查找与刚添加的工具提示控件同名的新属性。默认情况下，当光标悬停在控件上时，它会给出一个工具提示。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1253222|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Drag a tooltip control from the toolbox onto your form. You don't really need to give it any properties other than a name. Then, in the properties of the control you wish to have a tooltip on, look for a new property with the name of the tooltip control you just added. It will by default give you a tooltip when the cursor hovers the control.

blocks|key|1253282|text|只需订阅控件的ToolTipTextNeeded事件，并返回e.TooltipText，就简单多了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1253283|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Just subscribe to the control's ToolTipTextNeeded event, and return e.TooltipText, much simpler.

blocks|key|1468129|text|我是这样做的:只需将事件添加到任何控件，设置控件的标签，然后添加一个条件来处理适当控件/标签的工具提示。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1468130|private+void+Info_MouseHover(object+sender,+EventArgs+e)
{
++++Control+senderObject+=+sender+as+Control;
++++string+hoveredControl+=+senderObject.Tag.ToString();

++++//+only+instantiate+a+tooltip+if+the+control's+tag+contains+data
++++if+(hoveredControl+!=+"")
++++{
++++++++ToolTip+info+=+new+ToolTip
++++++++{
++++++++++++AutomaticDelay+=+500
++++++++};

++++++++string+tooltipMessage+=+string.Empty;

++++++++//+add+all+conditionals+here+to+modify+message+based+on+the+tag+
++++++++//+of+the+hovered+control
++++++++if+(hoveredControl+==+"save+button")
++++++++{
++++++++++++tooltipMessage+=+"This+button+will+save+stuff.";
++++++++}

++++++++info.SetToolTip(senderObject,+tooltipMessage);
++++}

I did it this way: Just add the event to any control, set the control's tag, and add a conditional to handle the tooltip for the appropriate control/tag.

<pre><code>private void Info_MouseHover(object sender, EventArgs e)
{
 Control senderObject = sender as Control;
 string hoveredControl = senderObject.Tag.ToString();

 // only instantiate a tooltip if the control's tag contains data
 if (hoveredControl != "")
 {
 ToolTip info = new ToolTip
 {
 AutomaticDelay = 500
 };

 string tooltipMessage = string.Empty;

 // add all conditionals here to modify message based on the tag 
 // of the hovered control
 if (hoveredControl == "save button")
 {
 tooltipMessage = "This button will save stuff.";
 }

 info.SetToolTip(senderObject, tooltipMessage);
 }
}
</code></pre>

I would like to display a <code>ToolTip</code> for when the mouse is hovering over a control.
How does one create a tooltip in code, but also in the designer?

How do I add a ToolTip to a control?

当鼠标悬停在控件上时，我想显示一个ToolTip。如何在代码中创建工具提示，也在设计器中创建工具提示？
