gridview用了HiddenField,数据绑定是用objectdatasource,update时如何才能不用更新这个HiddenField?
<asp:TemplateField SortExpression= "ImgUrlSml ">
<ItemTemplate>
<asp:HiddenField ID= "HiddenField1 " runat= "server " Value= ' <%# Bind( "ImgUrlSml ") %> ' />
</ItemTemplate>
</asp:TemplateField>
<asp:ObjectDataSource ID= "ObjectDataSource1 " runat= "server " SelectMethod= "GetProduct_Info "
TypeName= "ClassLibrary.Jkdata.JkDataBasic " UpdateMethod= "UpdateSimpleData " DeleteMethod= "DeleteData ">
<SelectParameters>
<asp:ControlParameter ControlID= "SearchTB " DefaultValue= "% " Name= "Name " PropertyName= "Text "
Type= "String " />
</SelectParameters>
<UpdateParameters>
<asp:Parameter Name= "ClassID " Type= "Int32 " />
<asp:Parameter Name= "Name " Type= "String " />
<asp:Parameter Name= "Content " Type= "String " />
<asp:Parameter Name= "AddTime " Type= "DateTime " />
<asp:Parameter Name= "IsShow " Type= "Boolean " />
<asp:Parameter Name= "ID " Type= "Int32 " />
</UpdateParameters>
