推荐答案
您必须在gridview的onrowdatabound事件中编写代码.
You have to write a code in onrowdatabound event of gridview.
如果您仅关注显示，您可以将函数插入
GridView来处理.在这种情况下，Id会使用IIF()作为帮助器
功能:
< asp:label id ="Label1" runat ="server" text =''<％#
iif(Eval("Gender")，"Male"，"Female")％>''></asp:label>
请参阅下面的完整代码.
让我们知道这是否有帮助?
If you are only concerned about the display, you can insert a function into
the GridView to handle that. In this case, Id use an IIF() as a helper
function:
<asp:label id="Label1" runat="server" text=''<%#
iif(Eval("Gender"),"Male","Female") %>''></asp:label>
See the full code below.
