OPTION 问题
<td   colspan= "2 "   id= "Arithmetic ">
<SELECT   style= "WIDTH:   100% "   onchange= "SfChange(this) ">
<OPTION   value=a   ' <%#   Microsoft.VisualBasic.Interaction.IIf(DataBinder.Eval(Container, "DataItem.Arithmetic ")== "a ", "selected ", " ")   %> '> a </OPTION>
<OPTION   value=b '   <%#   Microsoft.VisualBasic.Interaction.IIf(DataBinder.Eval(Container, "DataItem.Arithmetic ")== "b ", "selected ", " ")   %> '> b </OPTION>
</SELECT>
</td>

我想要从数据库查出来的是 "a "     <OPTION> a </OPTION> 就选中a
数据库查出来的是 "b "     <OPTION> b </OPTION> 就选中b
但是这样写不能实现功能
谢谢大家帮忙解决一下吧

VB

<OPTION value=b <%# Microsoft.VisualBasic.Interaction.IIf((DataBinder.Eval(Container.DataItem, "Arithmetic ")).ToString()= "b ", " selected ", " ")%> > b </OPTION>
