<p>In HTML in the td of a table you can break text by using <code>&lt;BR&gt;</code> between the words. This also works in the HeaderText of a TemplateItem but not the HeaderText of a BoundField. How do I  break up the Header text of a BoundField.</p>

Set
```
HtmlEncode = false
```
inside the
```
BoundField
```
```
```
<asp:BoundField DataField="SomeDataField" 
        HeaderText="SomeHeader<br />(OtherData)" 
        HtmlEncode="false" />
```
```
```
BoundField.HtmlEncode
```
is true by default which means that if HTML is added in the text it will be encoded.
If HtmlEncode is set to false the text is not encoded and the br will work as expected. Unfortunately is not possible to specify this only for the header text, it will affect the cell contents as well.
