  Hi Steve,

  This is just what I was looking for, and posted only 2 hours before I needed it, good timing! And a "local" too!

  One small thing... there is a slight typo in your code listing for FileImageTypesAttribute where you have got DefaultExtansions rather than DefaultExtensions.

  Many thanks,

  Rob

  Yep I can't type, I must have spell checked some of the code when I posted it to my blog but not all of it; sorry I try harder next time [:D]

  Hey Steve,

  Thank you very much for the code. I think I am missing something. This project is available for download in several places and I am not sure which one is the latest version.

   I am getting errors:

  The type or namespace name 'FileImage' could not be found (are you missing a using directive or an assembly reference?) 

  I think I am missing a class file. Can you point me to the latest download or email me the the complete project.

  Thanks again,

  Tareq

  Hey Steve, thanks a lot. I finally got it to work in VB. Now for the next step I need to use this FileImage image API with a custom page. It don't seem to work if I turn off the autogeneraterow to false. Is there a easy way to configure the custom page to use this API?

  Thanks,

  Tareq

  To use Dynamic Data with autogenerate turned off you have two options:

  1) Put a DynamicField into the list of columns for the GridView/DetailsView and specify the fieldname.

  2) Create a TemplateField and put a DynamicControl into the list of columns for the GridView/DetailsView and specify the fieldname.

  If this doesn't answer your question then show us an example of your data control with autogenerate turned off.

  It will not work if you set AutogenerateRow to false you must set up the columns using DynamicControl or DynamicField this allows the the GridView etc to put the correct FieldTemplate in place. To do this on a new page you will need to add an DynamicDataManager and point it at the the GridView etc control see below.

  DynamicDataManager1.RegisterControl(GridView1, true /*setSelectionFromUrl*/);

  whether your customising a page or creating a completely new page it's the same after that you must add the columns you want to display as in a normal customised gridview but replace the normal controls in the ItemTemplate/EditTemplate etc with DynmaicField/DynamicControl see below for an example of the columns collection.

  <Columns>
  	<asp:TemplateField>
  		<ItemTemplate>
  			<asp:HyperLink ID="EditHyperLink" runat="server" NavigateUrl='<%# table.GetActionPath(PageAction.Edit, GetDataItem()) %>' Text="Edit" />&nbsp;				 
  			<asp:LinkButton ID="DeleteLinkButton" runat="server" CommandName="Delete" CausesValidation="false" Text="Delete" OnClientClick='return confirm("Are you sure you want to delete this item?");' />&nbsp;				 
  			<asp:HyperLink ID="DetailsHyperLink" runat="server" NavigateUrl='<%# table.GetActionPath(PageAction.Details, GetDataItem()) %>' Text="Details" />
  		</ItemTemplate>
  	</asp:TemplateField>
  	<asp:TemplateField>
  		<ItemTemplate>
  			<asp:DynamicControl ID="DynamicControl1" runat="server" Mode="ReadOnly" DataField="Description">
  			</asp:DynamicControl>
  		</ItemTemplate>
  	</asp:TemplateField>
  	<asp:TemplateField>
  		<ItemTemplate>
  			<asp:DynamicControl ID="DynamicControl2" runat="server" Mode="ReadOnly" DataField="filePath">
  			</asp:DynamicControl>
  		</ItemTemplate>
  	</asp:TemplateField>
  </Columns>

  Hey Guys,

   I stumbled on another issue. Due to the line in insert.aspx

  FileImageHelper.DisablePartialRenderingForUpload(Me, table) is creating issue for me to to do a partial update on a template field inside the detailsview. More details of this post is posted here:

  http://forums.asp.net/t/1288000.aspx

   Whenever I try to update another updatepanel it keeps refreshing the main updatepanel. Any ideas how this can be resolved?

  Thanks again,

  Tareq

  The FileImageHelper.DisablePartialRenderingForUpload(Me, table) line disables partial rendering whenever there is a DBImage or FileImage FieldTemplate on the page due to the FileUpload having a security issue with partial render, so it's by design that the main updatepanel updates.
