iframe in console application

I have made a console application in Composite C1. This console application shows a list of dataitems. When you edit a dataitem it will show a tab with the information from the dataitem. On another tab I want to show a pdf that is referenced from the dataitem.

I would like to do it in the style of the 'Preview' tab when you edit a page.

So just an iFrame to show the pdf file.

Can anyone point me in the right direction to achieve this? Is it possible to create a preview like tab.

thanks in advance, Goldhorn

Solution

The auto generated data item editor view currently do not have support for preview.

You would need to either move the preview to a 'view' command you show in the tree or create a custom page to create the edit form/preview functionality.

Here is a sample Tree Definition file which shows how a new command is attached to an existing data element in the trees:

<ElementStructure xmlns="http://www.composite.net/ns/management/trees/treemarkup/1.0" xmlns:f="http://www.composite.net/ns/function/1.0"> 
  <ElementStructure.AutoAttachments> 
    <DataType Type="Composite.Data.Types.IPage" Position="Top" /> 
  </ElementStructure.AutoAttachments> 
  <ElementRoot> 
    <Actions> 
      <CustomUrlAction Label="View" Url="~/MyView.aspx?Id=${C1:Data:Composite.Data.Types.IPage:Id}" /> 
    </Actions> 
  </ElementRoot> 
</ElementStructure>

To make this hook on to your data type replace the two occurrences of "Composite.Data.Types.IPage" with your types full name (type namespace + name).

Tree definitions are stored as xml files in the folder ~/App_Data/Composite/TreeDefinitions - once you put the file there Composite C1 will pick it up, and in this case attach a command to some types of tree elements.
