DataList中ImageButton保存图片路径到session的问题
我想click DataList中的ImageButton时，怎样将Image的url地址写到session中？？

<asp:DataList ID= "DataList1 " runat= "server " DataKeyField= "PictureId "
DataSourceID= "PictureSystmeObjectDataSource " RepeatColumns= "2 " RepeatDirection= "Horizontal " >
<ItemTemplate>
<asp:ImageButton ID= "ImageButton1 " runat= "server " ImageUrl= ' <%# Eval( "PictureLocation ") %> ' />
</ItemTemplate>
</asp:DataList>

急。。 多谢！

[解决办法]
protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
{
ImageButton ImageButton1 = (ImageButton)e.Item.FindControl( "ImageButton1 ");
Session[ "ImageButton1Url "] = ImageButton1.ImageUrl;
}
[解决办法]
<asp:DataList ID= "DataList1 " runat= "server " OnItemCommand= "DataList1_ItemCommand ">
</asp:DataList>
