I followed the example online to download the attachment from a grid with a GridAttachmentColumn but I can't get the download working. The postback fires, ajax disables but the file is not sent. I am using Entity Framework.

I disabled ajax fine (ConditionalPostback, etc.) and can upload no worries. But I can't get the attachment to download direct from the datasource. All the examples I can find are for SqlDataSource.

When a parent record is expanded I want to evaluate and either show or hide the AddNewRecordButton on the multiple detail tables . I found that I can turn it off in the ItemDataBound event with this code.  Which appears to work until the grid  rebinds and then it applies to all records universally. I think I am coming at this from the wrong direction.  Is there a better way? 

HI,
excuse for my english am french
i start  to build my new back office manager with your solution.
they start to develop in dotnet (transfer  to  asp 3.0)

i build an news manager with
datagrid / insert-update-delete with usercontrol ( in datagrid)
my news manager use 2 racontrols : editor (they work fine !!!) and radupload for litle image of the news  all page are in masterpage :

In actu.aspx they have one raddatagrid they call webusercontrol.ascx

In webusercontrolascx they have radeditor and radupload.

this code work when they run in single page (not include in master page)

In masterpage the radeditor work well but the radupload return nothing I thinks i can’t find this control.
