SQL查询到gridview丢失\ n，如何将它们添加回来？

Question

我有一个简单的 gridview 显示，它从 SQL 查询中提取数据。我们数据库中的“刺绣细节”列是 4 行文本。我想在我的 gridview 中保留每一行文本，而不是显示为 1 行连续的文本。我该如何解决这个问题？

Answer 1

使用 TemplateField 而不是 BoundField。比如：

<asp:TemplateField>
<ItemTemplate>
<%# Replace(Container.DataItem("Embroidery Details"), vbCrLf, "<br/>") %>
</ItemTemplate>
</asp:TemplateField>
