#ZEN

Hi Guys,

Can you please advise me on how to display the content of the selected item/text from the drop down box listed item in our zen framework.

Thanks in advance.

Hi -

I'm trying to figure out an elegant way to select a row on a table pane when I don't have an index, but I DO have a value.

Zen report can create PDF document (https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=GRPT_xslfo_pdf_config ). Store your images in the table. Pass session id to the Zen report. Zen report will select images using SQL. The <img> element will insert images to the report:

If you are developing applications that use CSP or Zen, or potentially any of the other InterSystems web-related stuff that's built on top of CSP, then it's important to know how to keep one particular secret.

A central part of the CSP security architecture is a server-side session key. "Server-side" because its value should never be revealed to the client that is issuing the web requests. If it is revealed, a malicious client might be able to use it to bypass your security and make your server do things you don't want it to.

Hi!

Sometimes when I have Zen page in a browser (e.g. Management Portal page) and when my Internet connection interrupts, I see the alert window on the page, something like this screenshot:

​

Is there any setting for the CSP web app to prevent this alerts from popping up?

Has anyone configured Zen Reports/FOP to support png images? If you have, could you please share the library that you used, the configuration required, and whether it was worth it (vs converting images to one of the natively supported formats)?

Hello,

I have a question about how to set the value of a radioSet. Yes, I know -- the documentation says that setValue can be used "client side", but gives no example. Plus, I'm trying to set the value of a radioSet in %onAfterCreatePage, which is a Zen method? Server side method? I'm not sure.

In my Zen page I create a radioSet like this:

Greetings,

This code snippet provides a ZEN page that downloads a stream from its database directly:

/// We assume that you have stored your data within this schema:
/// MyApp.Model.Storage: Filename,FileSize,Content,ContentType
Class zen.downloadStream Extends (%ZEN.Component.page,%CSP.StreamServer)
{
 
    /// Wrapper to get the id of the download, we assume that the id is passed to this zen page
    /// as a URI parameter, i.e.: MyApp.Downloads.cls?OID=1234
    ClassMethod GetId()
    {
        Quit $Get(%request.Data("OID",1))
    }
     
    /// Set the appropriate header for the file.
    ClassMethod OnPreHTTP() As %Boolean
    {
        Set tId = ..GetId()
     
        If ##Class(MyApp.Model.Storage).%ExistsId(tId) {
            Set tStream = ##Class(MyApp.Model.Storage).%OpenId(tId)
            // You could "guess" the content type by its file extension
            // or you can store it (before) in the database separately (like in this example).
            // Set Extension = $Piece(tStream.Filename,".",$Length(tStream.Filename,"."))
            // Set ContentType = ..FileClassify(Extension)
     
            Set %response.ContentType = tStream.ContentType
            Do %response.SetHeader("content-disposition","attachment; filename="_tStream.Filename)
            Do %response.SetHeader("Content-Length",tStream.FileSize)
        }
        Else {
            Set %response.Status="404 File Not Found"
            Quit 0
        }
        Quit $$$OK
    }
     
    ClassMethod OnPage() As %Status
    {
        Set Download = ##Class(MyApp.Model.Storage).%OpenId(..GetId())
        Do Download.Content.OutputToDevice()
        Quit $$$OK
    }

Hi,

Is it possible to have a ZEN Mojo application that uses Bootstrap and controls from jQMobile ?

In a fresh installation running Zen Mojo version 1.1.1, my ZEN Mojo page declares:

Hi,

I am trying to create a new dashboard using zen page for different namespaces. Could someone give me a sample code on how I can start designing the page for different namespaces in a single zen page/zen application.

The dataCombo property columnHeaders is a comma-delimited list of column headers displayed in the dropdown list.

Comma is a delimiter.

But, if I want add comma to columh header, for instance "House number, apartment" - this is value for header of one column.

How can I escape comma in this case?

"House number\, apartment" - is not working.

Hi everyone!

Someone already try to use jQuery Mask Plugin on cache?

Hi all,

I've been looking for a way to extract the sorting from the ^CacheTemp.zenData global that contain the tablePane snapshot data in order to use it on a report following the current UI sorting criteria.

I could see that if the column is sorted by one column, new entries with this structure are created:

^CacheTemp.zenData(<sessionId>,<snapShotId>,<tablePaneId>,"index",<columnId>,<value>,<dataId>)=""
