ASPxGridView之PreviewRow

3、设置grid的数据源为objds，此时grid会自动绑定所有列。为了展示较长字段，必须制定为PreviewRow赋值为一列名，并且让PreviewRow显示。如下图设置。我这里是PreviewFieldName="FTI_MARK"，<Settings ShowPreview="True" />

4、在页面中展示的效果如下图。我们发现FTI_MARK不为空才显示，整体看起来样式不统一，而其别人不知道这一行是展示的什么数据。怎么办呢？可以使用Templates 中PreViewRow。

5、在设计模式下，鼠标定位于aspxGridView,点击右上角的三角形，选择编辑模板。

使用Templates 中PreViewRow。

6、在PreViewRow中拖放进一个Table,修改为一行2列。第一列写列名，备注，第二列写数据，<%#Eval("FTI_MARK")%>

这样无论FTI_MARK有没有数据都显示，而其我们可以加进别的有用信息。效果如下图：
