ASPxGridView EditForm ASPxRadioButtonList 报错解决办法
是因为没有指定 ValueType
<dx:ASPxRadioButtonList ID="ASPxRadioButtonListObjectType" runat="server" RepeatDirection="Horizontal"
ValueType="System.Int32" Value='<%# Bind("ObjectType") %>'>
<Items>
<dx:ListEditItem Value="0" Text="全部" />
<dx:ListEditItem Value="1" Text="学员" />
<dx:ListEditItem Value="2" Text="教职工" />
</Items>
</dx:ASPxRadioButtonList>
