Setting GridView header text to wrap as directed
提问by
I have a GridView that has columns such as:
我有一个 GridView，其中包含以下列：
| A | B C | D E / F |
I want these to be wrapped in a particular way - that is, I do not want to leave it up to the browser to work out whether to wrap or not depending on the column width. So in the above example I may want the following:
我希望这些以特定方式包装 - 也就是说，我不想让浏览器根据列宽来确定是否换行。所以在上面的例子中，我可能想要以下内容：
| A | B | D |
| | C | E / F |
I have tried using \nand also using <br/>however both of these did not work.
我曾尝试使用\n和使用，<br/>但是这两种方法都不起作用。
Any ideas?
有任何想法吗？

You can do it without templates. Just set HtmlEncode="False" on the headers with <br />tags in them.
您可以在没有模板的情况下完成。只需在带有<br />标签的标题上设置 HtmlEncode="False"即可。
Example:
例子：
<asp:GridView ID="GridView1" runat="server" DataSourceID="Data">
<Columns>
<asp:BoundField HeaderText="First Line<br />Second Line" DataField="ContactID"
HtmlEncode="False" />
<asp:BoundField HeaderText="Second" DataField="FirstName" />
<asp:BoundField HeaderText="Third<br />Extra" DataField="Title" />
</Columns>
</asp:GridView>
Renders:
渲染：
First Line | Second | Third<br />Extra | Second Line | | | --------------------------------------------- 1 | Gustavo | Mr. | --------------------------------------------- 2 | Catherine | Ms. | ---------------------------------------------
NOTE: If you use the Designer rather than editing the aspx directly, it will change your "<" into "<" when you click OK.
注意：如果您使用设计器而不是直接编辑 aspx，当您单击“确定”时，它会将您的“ <”更改为“ <”。

If you use a template field, you can have fine grain control the header content in the header template:
如果您使用模板字段，则可以对标题模板中的标题内容进行细粒度控制：
<asp:templatefield>
<headertemplate>
D<br />
E / F
</headertemplate>
<itemtemplate>
<%#Eval("MyField")%>
</itemtemplate>
</asp:templatefield>
