Hi Icebits, Bill on http://www.myvbprof.com/2007_Version/Dynamic_Data_Tutorial.aspx Is working on converting some of my samples to VB for his tutorials and videos I don't know how far he's got yet but you could e-mail him and ask if he's doning a conversion.

Hope this helps

Have you had a look at this article Dynamic Data: Part 2 - FileImage_Edit FieldTemplate of mine it does everything you want but works with images I'm sure it could be modified to do files and just show filename and a fieltype image

If you are loading images from the database you can try the Dynamic Data Futures which has support for images in the database. It contains an ImageFormat attribute which allows for scaling of images.

Tareq:
Has anyone implemented a image handler to handle the image size? I was trying to tie it to the personal starter kits image handler but not able to.

Hi Tareq I don't know if this is the sort of thing you mean, have a look at this Dynamic Data: Part 2 - FileImage_Edit FieldTemplate

Hope this helps

I think I am not getting your advice here and still doing something wrong. I removed the main updatepanel and it still is not working for partial update. Do I have to remove the updatepanel outside of the detailsview as well for it to work. I kept the upload control ouside of the updatepanel and placed the update panel inside of detailsview template. Here is my current code:

<asp:DetailsView ID="DetailsView1" runat="server" DataSourceID="DetailsDataSource"

DefaultMode="Insert" OnItemCommand="DetailsView1_ItemCommand"

OnItemInserted="DetailsView1_ItemInserted" CssClass="detailstable"

FieldHeaderStyle-CssClass="bold" AutoGenerateRows="False" DataKeyNames="id">

<asp:DynamicField DataField="submitted_by_name" HeaderText="Name"

SortExpression="submitted_by_name" />

<asp:DynamicField DataField="submitted_by_email" HeaderText="Email"

SortExpression="submitted_by_email" />

<asp:DynamicField DataField="filename" HeaderText="Select Image"

SortExpression="filename" />

<asp:DynamicField DataField="keywords" HeaderText="Keywords"

SortExpression="keywords" />

<asp:DynamicField DataField="location" HeaderText="Location"

SortExpression="location" />

<asp:DynamicField DataField="image_credits" HeaderText="Image Credits" SortExpression="image_credits"

<asp:TemplateField HeaderText="Project Related"

SortExpression="project_related">

<asp:CheckBox ID="chkProjectRelated" runat="server" AutoPostBack="True"

Checked='<%# Bind("project_related") %>'

oncheckedchanged="chkProjectrelated_CheckedChanged" Text="Project Related" />

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<asp:Panel ID="projectinfo" runat="server" Visible="false">

<asp:DynamicControl ID="DynamicControl1" runat="server"

DataField='project_name' Mode="Insert"

></asp:DynamicControl>

<asp:DynamicControl ID="DynamicControl2" Mode="Insert" runat="server" DataField="project_number"

></asp:DynamicControl>

<asp:DynamicControl ID="DynamicControl3" Mode="Insert" runat="server" DataField="project_manager"

></asp:DynamicControl>

<asp:DynamicControl ID="DynamicControl4" Mode="Insert" runat="server" DataField="IndustryCategory" ></asp:dynamiccontrol>

<asp:DynamicControl ID="DynamicControl5" Mode="Insert" runat="server" DataField="FacilityCategory" ></asp:dynamiccontrol>

<asp:DynamicControl ID="DynamicControl6" Mode="Insert" runat=server DataField="project_client"></asp:DynamicControl>

</asp:Panel>

</ContentTemplate>

<asp:AsyncPostBackTrigger ControlID="chkProjectRelated"

EventName="chkProjectRelated_CheckedChanged" />

</Triggers>

</asp:UpdatePanel>

</InsertItemTemplate>

</asp:TemplateField>

<asp:CommandField ButtonType="Button" DeleteText="" EditText=""

InsertText="Submit Image" NewText="" SelectText="" ShowInsertButton="True"

UpdateText="" />

</Fields>

</asp:DetailsView>

What am i still doing wrong?

Thanks,

Tareq

Here is a blog post by one of our fellow ASP.NET team members that explains in detail why FileUpload does not work inside of an UpdatePanel: http://weblogs.asp.net/leftslipper/archive/2007/03.aspx

As I said, you cannot have a FileUpload inside of an active UpdatePanel. It is simply impossible for them to work together.

I am seeing the whole refresh but I want only partial refresh.

Hi Tareq,

you cannot have a FileUpload control inside of an update panel that has partial updating enabled. By default, the Dynamic Data page templates are contained inside an UpdatePanel. What the DisablePartialRenderingForUpload method does is disable partial updating for the whole page if Dynamic Data would display a column with a FileUpload control. Are you sure that you are not seeing the whole page refresh?

You could remove the call to the DisablePartialRenderingForUpload method but you would have to place all Dynamic Data data controls (like the DetailsView) outside of UpdatePanels.

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.

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
