String Formatting Not working with Eval
提问by LCJ
I have following expression for currency formatting inside an ASP.Net Gridview. It does not show dollar format though there is no error. What is the missing point here?
我在 ASP.Net Gridview 中有以下货币格式表达式。虽然没有错误，但它不显示美元格式。这里的缺失点是什么？
<%# String.Format("{0:C}", Convert.ToString(Eval("Amount")) ) %>
MARKUP

Why not just do either...
为什么不做任何...
<%# String.Format("{0:C}", Eval("Amount") ) %>
or
或者
<%# ((int)Eval("Amount")).ToString("C") %>
Looks to me like you are trying to convert Amount to a string twice, and you can't format a string as currency.
在我看来，您正试图将 Amount 转换为字符串两次，并且您无法将字符串格式化为货币。

try this :
尝试这个 ：
<%# String.Format("{0:C}", int.Parse(DataBinder.Eval(Container.DataItem, "Amount").ToString())) %>

try this, works for me. (.NET 4.5 C#, in a gridview)
试试这个，对我有用。（.NET 4.5 C#，在网格视图中）
<%#Eval("Amout", "{0:C}").ToString()%>

Evalaccepts a string format, and there is no need for these hacks.
Eval接受字符串格式，不需要这些技巧。
As simple as: <%# Eval("Amount", "{0:C}") %>
就这么简单： <%# Eval("Amount", "{0:C}") %>
