Get url of document referenced in custom module

Hi,

I have a custom module with a field that has a reference to a document, specifically a PDF file I have uploaded to Sitefinity.  I also have a custom widget to render this module to the page.  I want to be able to create a hyperlink to the PDF file of the current module but am having trouble extracting it when using a <%# Eval %> tag.

Thanks,
Richard

I still haven't been able to come up with what I consider the correct way to do this but I have narrowed down the issue and come up with a work around.

Richard, I'm sorry I didn't get a chance to reply to your post sooner. however, you have indeed discovered the best way to currently do this kind of databinding in a custom control or template.

Using a helper method is the same process I used for this blog post: Retrieving Data From Dynamic Modules Using the Module Builder API. the example uses an image, but the process is the same, as all media items are stored as an array of Guids. As you mentioned, if a single item is specified, the array will be one item long, and be in the first index.

The module builder team is aware of this limitation and I am confident that they are addressing the issue. I'm not sure if this will be improved in the next release but I do know they are working on it. Thank you kindly for your feedback about this, and for updating the community with your progress!

Thanks, I'll keep an eye out for any updates but it's good to know I was completely off base in my work-around.

Hi @SelAromDotNet and Richard,
I am also stuck to the kind of same problem. I have a list of employees where each employee has a document uploaded for it and instead of ussing Sitefinity Assetfield I am using a Link Button. On Link button click i am throwing my own implementation of email verification with JQuery. In my code behind I can get hold on to the "GetDataItems" that return me the collection of employees but when I go for "GetDataItem" it also ask me to provide the "GUID ID" that I dont have and in my code snippet the <%# Eval("Id") %> is the GUID ID, i-e. holding the collection (array) of guids and I dont know how to get the specific clicked guid from here.  Could you please give me some idea how I can get hold on to the document that I clicked so that I can get this document downloaded in my code behind file? Any help will really be appreciated. Following is my code snippet

<telerik:RadListView ID="dynamicContentListView" ItemPlaceholderID="ItemsContainer" runat="server" EnableEmbeddedSkins="false" EnableEmbeddedBaseStylesheet="false">
    <LayoutTemplate>
        <ul class="employee-list">
            <asp:PlaceHolder ID="ItemsContainer" runat="server" />
        </ul>
    </LayoutTemplate>

        <ItemTemplate>
      <li class="employee">
          <h2 class="sfitemTitle">
              <sf:DetailsViewHyperLink ID="DetailsViewHyperLink" TextDataField="Title" runat="server" />
          </h2>
          <sf:AssetsField ID="AssetsField1" runat="server" DataFieldName="Picture"  CssClass="employee-image"/>
          <sf:SitefinityLabel ID="SitefinityLabel1" runat="server" Text='<%# Eval("Designation")%>'  WrapperTagName="div" HideIfNoText="true" CssClass="sfitemShortTxt" />          
          <sf:SitefinityLabel ID="SitefinityLabel2" runat="server" Text='<%# Eval("CompanyName")%>' WrapperTagName="div" HideIfNoText="true" CssClass="sfitemShortTxt" />
         
   <div id="evalid" runat="server">
              <%# Eval("Id") %>
          </div>
         
 <asp:LinkButton Runat="server" ID="DownloadLnkButton" Text="Download" CssClass="employee-document"/>
      </li>
    </ItemTemplate>
</telerik:RadListView>

<div class="dialogTest" visible="false"> <br /><br />
    Please enter your email address: <asp:TextBox CausesValidation="true" ID="txtEmailAddress" runat="server" style= "Width: 300px;" /> <br/>

    <asp:RequiredFieldValidator runat="server" ID="RequiredFieldValidator1"
        ControlToValidate="txtEmailAddress" ErrorMessage="Email is required" />
   
    <asp:RegularExpressionValidator runat="server" ID="RegularExpressionValidator1"
        ControlToValidate= "txtEmailAddress"
        ErrorMessage="Please enter a valid email address!"
        ValidationExpression= "^([a-zA-Z0-9_\-\.]+)@((\[[0-9]1,3\.[0-9]1,3\.[0-9]1,3\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]2,4|[0-9]1,3)(\]?)$"/> <br/>
    <asp:Button ID="btnSubmit" runat="server" Text="Submit" CausesValidation="true"/>
</div>

<script type="text/javascript">
    $j = jQuery.noConflict();
    $j(document).ready(function ()
        $j(".employee-image img, .employee-document").click(function ()
            $j(".dialogTest").addClass("open");
        );
    );
</script>

I'm having the same problem. Is it possible to get the document url from the widget template without modifying code behind?  I don't have access to the code behind (that I know of) and our IT staff will not likely be able to help out.   Any way to access the data just via the template widget and maybe some js or am I out of luck?

Hi Matt, you might be able to find what you need by using the AssetsField control on the widget template. You can find out more about that control in this thread: www.sitefinity.com/.../module-builder-and-images

I hope this is helpful!

Thanks for the Reply. I am trying to use the AssetsField but it is not showing the link to the document.  I think it may have something to do with the difference between RadListView and DynamicDetailContainer.  I am trying to get it to show up on RadListView, I don't need a details page, but when I do have a details page it seems to show up fine.  Below is my template code. It doesn't throw an error however nothing shows up for the BillInsert AssetField. Any idea what would cause that issue?

Hello,

The approach with using AssetsField is correct and applying it at my end I am able to render the link to a document as well for an image as shown in your widget template.
Here is a video of the behavior at my end.

I think there is either cache or a glitch that prevents the rendering of the rendering of the document link. I suggest removing the ImageAssetsField form the widget template and then saving it. The image will be removed and I think must refresh the widget template and the link to document will show. After this add the ImageAssetsField control again to the template.

Hi Stanislav, thanks for the reply. It turns out that the link was working and showing up, it's the fact that I was looking at the page in Preview and the link wouldn't show up there for some reason. as soon as I published the page, it started working.

I was able to get the document link from the widget template using <sf:assetfield>, but is there a way to also get the document's file size?  Much like what is displayed in the document download list widget?

Hi,

The size can be retrieved with getting the first document in the BillInsert field and the property ChildItemAdditionalInfo
