How to make sub-class properties to render at designer (Studio) ?

Samuel Pizarro — Tue, 14 Jul 2026 17:24:57 GMT

Trying to sub-class cWebButton, to make easier to implement font-icons without having to keep adding custom classes for each icon inside application.css file.

Was able to make it work at runtime. but Can't make the icon to render at designer..

Basically, I added a new client web-property to specify the icon, and changed the render logic to inject the html before the button caption.
At Studio , design time:
ButtonIcons_webdesigner_01.png
1st one uses built-in font icon. all others uses the sub-class new property :

Code:

Set psIconHtmlTag to 'search'

At runtime
ButtonIcons_webdesigner_02.png

What is the trick ?

Ps. I don't know why, it does work for Tiles in the dashboard, but tiles are not subclassed.. just adding the span as part to the tile inner html.

ButtonIcons_webdesigner_03.png
Tile psHtml :

Code:

Set psHtml to 'search
Material Symbols
'

So, the designer can detect my css settings.. but it does not work for sub-classed new web-properties.. it makes me think that it is not rendering it at design time.

Password

Tom — Tue, 14 Jul 2026 16:53:58 GMT

Hi,

We are doing an upgrade to DF 25.0 WebApp for an internal barcode scanning system. Our scanners do not require a password but it appears that the DF 25.0 WebApp does.
What is the easiest way to skip the use of a password on the DF 25.0 WebApp?

Thanks,
Tom

cWebModalDialog with pbServerOnShow = True does not return focus to the invoking object after closing

felipesilva — Fri, 10 Jul 2026 13:47:30 GMT

Hi DAW,

(DF25 + FIREFOX)

We identified an issue related to the use of cWebModalDialog when the pbServerOnShow property is set to True.

Scenario

1 - We have a cWebModalDialog opened through a prompt.
2 - When the dialog is opened with pbServerOnShow = False, the focus behaves as expected: after closing the dialog, focus returns to the invoking object.

However, when the pbServerOnShow property of the cWebModalDialog is set to True, the behavior changes.

Observed issue

After closing the cWebModalDialog, focus does not return to the object that invoked the prompt. The focus gets lost instead of returning to the original control.

Summary

1 - cWebModalDialog opened through a prompt
2 - pbServerOnShow = True
3 - after closing the dialog, focus does not return to the invoking object
4 - focus gets lost

I would like to confirm whether this behavior is already known and whether there is any guidance or fix for this scenario.

Thanks

Felipe Silva

Widgets

sjwalter — Fri, 10 Jul 2026 13:36:52 GMT

I'm trying to create a widget that provides the same functionality that previous versions of Dataflex provided on the dashboard. Mainly, something along the lines of the old Recent Orders list in the previous Web Order Mobile.
OldDashboardList.jpg

I've got my widget designed and it looks correct in the Studio modeler, but when it runs, I just get a blank box with nothing to see or click on. I didn't include a code snippet since this is really known code from previous versions, but I can include my code if that would help.

Is there a secret to recreating this older functionality in a widget? The docs are woefully inadequate for the widget system right now, which I hope will be improved in the future.

cWebList (data aware): is possible update the current row during row navigation?

felipesilva — Thu, 09 Jul 2026 17:13:25 GMT

Hi all,

I have a question about **cWebList**.

Is there a supported way to **update the current row while navigating through the list**, specifically when the user changes the selected row?

This is a **data aware cWebList**.
My scenario is that, during row navigation, I need to update the data displayed in the current row without requiring a full list refresh afterwards.

In other words, when the user moves from one row to another, I would like to update the row being navigated (or the current row) while the navigation is happening.

I know there are approaches for updating rows in manually loaded lists, but in this case the list is bound to the database, so I am not sure what the recommended approach is.

Is there any supported way to do this in a data aware cWebList?
If so, what would be the best practice?

Thanks.

golden oldie - Error 999 unhandled program error on client

Trying to install Toast on DF25 and my include of the WebToast.js isn't visible if I examine source. Restarted, cleared cache, changed browsers...
and yes js and css file are present under DfEngine

edit: whereas what I SHOULD have done was made sure the Virtual Directory for the earlier toast-less version of this was no longer in existence, because changing the Appname solved the problem.

cWebList hide vertical scrollbar

JeffKimmel — Tue, 07 Jul 2026 19:26:55 GMT

All,

Is there a way to hide the vertical scroll bar in lists in 23.0? Setting pbScroll doesn't seem to work for me because the web app scrolls up the screen when scrolling down the list. I've tried messing with the css but can't get the right combination. Any help welcome.

Thanks,

Jeff

WebApp Hanging After Adding Server-only Index

MisterM — Mon, 29 Jun 2026 16:19:32 GMT

Has anyone ever run into a problem with their web app hanging on load after adding a Server-only index in MSSQL to a table referenced by a WO?

Here's the situation: On Tuesday, I added an index in our development environment to speed up a slow query using a TVF, as suggested by SSMS's Actual Execution Plan. On Wednesday or Thursday, we discovered that the web app wasn't loading anymore, just coming up with a white page and eventually an error 500. Doing all the normal checks, we couldn't figure it out. The error message written to the Windows Event Log was less than helpful, just telling us it was not responding and being force closed. Today, after trying a number of other things, we finally tried running and pausing the load inside the debugger and found that it was hanging up on

Code:

Send Add_User_Interface to hoServer Self

inside Attach_Deo_To_Server when doing End_Construct_Object on a WO. Looking at the history on the parent table for the list in that WO, the only thing we could see that'd changed recently was me adding a SQL index. It's not being explicitly or directly referenced by anything in the code, but I dropped the index and magically WebApp loads.

Why in the world would adding a server-side index that's not being referenced cause a list to hang up when loading? There's 3 other ones already on the table, so why did this one make it break?

We're still running 19.1, if that makes any difference...

OnViewSaved

Peter Bragg — Fri, 26 Jun 2026 14:44:47 GMT

It would be quite useful if within OnViewSaved it were possible to know if this is a newly created record, or an existing one that was edited - perhaps an extra argument that gets passed (which would then not break existing code).
I know it doesn't take much code to set a property and then interrogate it, but it does feel (to me) like useful information to have within an event that fires when a record is saved.

SelectView Using Wrong DDO

Tom Murphy — Fri, 26 Jun 2026 01:55:59 GMT

Hi DAW

Similar to my last post, I have a webview with 2 webcards and each webcard has it's own server structure like tab views in Windows.

In each webcard I have the same DataDictionary class defined and a webform bound to a column in it. When I drill down to a select view on the webform on webcard1 it attempts to find the record in the webcard2 ddo not webcard1.

This is because all the DDO's in the webview are in the paDDOIndex property and FindDDOForTable finds the first DDO that matches the table number from the select view.

WebCard DEO Errors

Tom Murphy — Wed, 24 Jun 2026 07:22:04 GMT

Hi DAW

I have a view with multiple web cards with their own DDO server structures. Where 2 cards have a web form pointing to the same file.field first web form on the first web card takes the focus and not the second one that had the error.

As far as I can see this is because the FirstControlWithDataBinding method in cWebErrorHandler just looks for the first child object in the view that has the same file.field binding.

Take the view as an example...

Code:

Use cWebView.pkg

Use cWebForm.pkg 

Use cInventoryDataDictionary.dd

Use cOrderHeaderDataDictionary.dd

Use cOrderDetailDataDictionary.dd





Object oValidateTest is a cWebView

    Set piWidth To 1024

    Set psCaption To "Validate Test"

    Set piColumnCount To 12

    

    Object oInventory_DD is a cInventoryDataDictionary

        Set Foreign_Field_Option DD_KEYFIELD DD_FINDREQ To False

        Set Foreign_Field_Option DD_INDEXFIELD DD_FINDREQ To False

        Set Field_Option Field Inventory.Item_ID DD_REQUIRED To False

    End_Object





    Object oOrderHeader_DD is a cOrderHeaderDataDictionary

        Set DDO_Server To oInventory_DD

    End_Object





    Set Main_DD To oOrderHeader_DD

    Set Server To oOrderHeader_DD





    Object oButton1 is a cWebButton

        Set psCaption To "Card 1"

        

        Procedure OnClick

            Send Show Of oCard1

        End_Procedure

    End_Object





    Object oButton2 is a cWebButton

        Set psCaption To "Card 2"

        Set piColumnIndex To 1

        

        Procedure OnClick

            Send Show Of oCard2

        End_Procedure

    End_Object





    Object oContainer is a cWebCardContainer

        Object oCard1 is a cWebCard

            Object oOrderHeader_Order_Date is a cWebForm

                Entry_Item OrderHeader.Order_Date

                Set piColumnSpan To 0

                Set psLabel To "Order Date:"

            End_Object

            

            Object oOrderHeader_Item_ID is a cWebForm

                Entry_Item Inventory.Item_ID

                Set piColumnSpan To 0

                Set psLabel To "Inventory Item ID:"

            End_Object

        End_Object





        Object oCard2 is a cWebCard

            Object oInventory_DD is a cInventoryDataDictionary

            End_Object





            Object oOrderDetail_DD is a cOrderDetailDataDictionary

                Set DDO_Server To oInventory_DD

            End_Object





            Set Main_DD To oOrderDetail_DD

            Set Server To oOrderDetail_DD





            Object oOrderDetail_Item_ID is a cWebForm

                Entry_Item Inventory.Item_ID

                Set piColumnSpan To 0

                Set psLabel To "Inventory Item ID:"

            End_Object





            Object oOrderDetail_Qty_Ordered is a cWebForm

                Entry_Item OrderDetail.Qty_Ordered

                Set piColumnSpan To 0

                Set psLabel To "Quantity Ordered:"

            End_Object

        End_Object

    End_Object

End_Object

When I go to the card 2 and tab out of oOrderDetail_Item_ID it gives the focus to oOrderHeader_Item_ID on card 1 and shows the error there. Note the oOrderHeader_Item_ID is optional and oOrderDetail_Item_ID is required.

Getting this one fixed is pretty important for us.

Change in RecreateSession

JeffKimmel — Fri, 19 Jun 2026 16:13:55 GMT

All,

I'm converting my app to 23 & ran into an issue with onLoad and RecreateSession. After the user successfully logs in, I use onLoad to check the company type & use this info to show/hide menu choices. In the past, I could log out, which calls recreateSession & then when I log in as a different user, onLoad is now not hit & the wrong menu options are displaying. Is there something I can do to force the app to really recreate itself & force onLoads to get called again?

Also, I thought I read on the board here that there is an onPreShow or something like that but I can't find it in the help anywhere. Is there an onPre something that I'm not seeing?
Edit - onBeforeShow

Thanks,

Jeff
