How To Force webView to scroll-up (TOP) after saving ?

Samuel Pizarro — Thu, 03 Sep 2026 19:07:30 GMT

DrillDown mode.

Special zoom view that is not closed after saved.. Customer want's to see the final record details (several calculations in DD which is reflected just after saved) and keep the saved record opened in the view but in readOnlyMode.

Was able to keep the view opened and show in readOnly mode, but not beeing able to make the view to scroll-up so user can see the beginning of the view header.
Yes small device, and view is taller than screen size.

Already tried to manipulate Send Focus to 1st form after saving and before entering in read-only mode, but it does not work !

Issue: Stale row selection with keyboard navigation in cWebMultiSelectList

Shameed — Fri, 28 Aug 2026 02:52:15 GMT

Hi all. My team has encountered a bug with keyboard navigation in the cWebMultiSelectList class. I haven't seen a post discussing this specific issue, so I thought I'd report it here.

Below: the incorrect behaviour, steps to replicate it in WebOrder, the location of the bug in the df-min.js code, and a suggested fix.

The Behaviour

Using keyboard navigation on some cWebMultiSelectLists causes the list to correctly clear on row navigation, but the previous row stays selected while the new current row remains unselected.

Steps to Replicate

In DemoWebMultiSelect.wo, set the following properties on oDetailsGrid:

Code:

Set pbOfflineEditing to False

Set pbSelectionByRow to True

Navigate up or down with the keyboard and you should see the misbehaviour described above.

Bug Location in df-min.js

keyDown() (in class De) calls super.keyDown(), then, if pbSelectionByRow is True, immediately sets whatever the current row is to selected:

Code:

if (t.matchKey(r.settings.listKeys.scrollUp) || t.matchKey(r.settings.listKeys.scrollDown) || t.matchKey(r.settings.listKeys.scrollPageUp) || t.matchKey(r.settings.listKeys.scrollPageDown) || t.matchKey(r.settings.listKeys.scrollTop) || t.matchKey(r.settings.listKeys.scrollBottom)) {

    let t = super.keyDown(e);

    return i.pbSelectionByRow && (this.clearSelection(),

    this.setCurrentRow(!0)),

    this._iBeginRange = -1,

    t

}

However, when pbOfflineEditing is False, super.keyDown() does not yield a synchronous update to the current row.

In selectRow (class ee, a superclass of De), the current row is only updated via this.setCurrentRowId(h) when pbOfflineEditing is true:

Code:

selectRow(e, t, i, s) {

    const o = this.oL

      , n = this.oM

      , a = n.sCurrentRowId;

    let l = !0

      , h = ""

      , d = s || null;

    o.cancelServerAction("ChangeCurrentRow"),

    "row" === e && (h = n.rowIdByRowIndex(t),

    l = null !== h && h !== a,

    o.pbDataAware || (d = n.aData[t]));

    const p = {

        sPrevRowId: n.sCurrentRowId,

        iPrevRowIndex: n.iCurrentRow,

        sGotoRow: h,

        iGotoRowIndex: t

    };

    this.iRowChangeCount++;

    const u = this.iRowChangeCount;

    function c(e) {

        var t = u !== this.iRowChangeCount;

        p.bSuccess = r.toBool(e),

        n.onAfterRowChange.fire(n, p),

        o.pbOfflineEditing || r.toBool(e) ? i && i.call(this, !0, t) : i.call(this, !1, t)

    }

    l ? (n.onBeforeRowChange.fire(n, p),

    o.pbOfflineEditing ? ("row" === e && (this.setCurrentRowId(h),

    this.updateColumnsFromCache(!0)),

    c.call(this)) : (this.handleRowChange = c,

    o.serverAction("ChangeCurrentRow", [e, h], d && o.serializeRows([d]) || null))) : i && i.call(this, !1)

}

When pbOfflineEditing is False, the current-row update is deferred to a server round trip (serverAction("ChangeCurrentRow", ...)), with c stashed as this.handleRowChange to run once the server responds. So by the time keyDown calls clearSelection() / setCurrentRow(!0), sCurrentRowId still points at the previous row that's the row that gets re-selected, while the real new row never gets a selection call at all.

Summary: when pbOfflineEditing is False and pbSelectionByRow is True, a stale row is selected instead of the new current row.

Suggested Fix

Block the premature setCurrentRow call in keyDown when offline editing is off:

Code:

if (t.matchKey(r.settings.listKeys.scrollUp) || t.matchKey(r.settings.listKeys.scrollDown) || t.matchKey(r.settings.listKeys.scrollPageUp) || t.matchKey(r.settings.listKeys.scrollPageDown) || t.matchKey(r.settings.listKeys.scrollTop) || t.matchKey(r.settings.listKeys.scrollBottom)) {

    let t = super.keyDown(e);

    return i.pbSelectionByRow && (this.clearSelection(),

    i.pbOfflineEditing && this.setCurrentRow(!0)),

    this._iBeginRange = -1,

    t

}

And override selectRow's callback in class De so the current row gets selected once the row change actually completes, as originally intended:

Code:

function c(e) {

    var t = u !== this.iRowChangeCount;

    p.bSuccess = r.toBool(e),

    n.onAfterRowChange.fire(n, p),

    o.pbOfflineEditing || r.toBool(e) ? i && i.call(this, !0, t) : i.call(this, !1, t)

    this.setCurrentRow(!0)

}

I'm not certain this will work exactly as-is because I'm unsure whether handleRowChange runs before or after the current row ID is updated by the DF client. If it runs after, this should be sufficient.

Changing to web-app server 25.0 on a server with old Webapp 20.1, cahcing problems

MrHalland — Thu, 27 Aug 2026 07:02:56 GMT

Hi!

I have IIS server at a customers site, they were running Webapp 20.1 on a Site called CustomerWeb.

Now I installed the DF Web 25.0 on the same machine, created a new site called CustomerWeb250
Added everyting but the binding for testin, all works out.

Then i stoped the old web-site, removed the bindings and added them to the new site.
Starting all up, tested to enter the domain, no problems.

How ever, a lot of their customers get, error 500 when accessing the site now. I told the customer to press CTRL+F5 to force reload of the site to clear the cache, and it does work.
But all customers doesn't call or understand that they must / can press that to refresh.

Is there a way to avoid that?

I do have separate application pools, i have recycled the new one, restarted the IIS site as well as the web-app.

Added info in config file and index.html files to not store cache in the future.

cWebGrid - (a) sometimes it won't allow down arrow to next row, (b) row 2 deleted

Nicholas Herlick — Fri, 21 Aug 2026 16:52:12 GMT

I'm creating a program to import csv data into a prospect table. Clicking [Field Map] button loads a grid row for each fieldname in the csv header (col 0), and sample data from csv row #2 (col 2). The last column is a cWebColumnCombo which lets user chose a target map-to field in the prospect table. The cWebGrid is not data aware, so it uses Send GridRefresh to call OnManualLoadData to load the grid, an initial loading of the grid that works fine.

So next, I click into the target map-to field (last column) and choose a target field from the combo list. No Problem. But when I hit down arrow to advance to grid row 2, it deletes that grid row and moves up row #3 to occupy row #2. This only happens once - subsequent rows do not suffer from that behavior. It's a total head scratcher - I have no logic that would delete a grid row.

The other issue is that while the focus is in the last column - the cWebColumnCombo - if I do not choose a map-to field, wishing to leave the entry blank (which means "ignore this field") the focus is stuck there. I have to choose a target field value to be allowed to move down to the next row. I've tried using Set pbAddEmptyItem to True and Set psEmptyItemDescription to "". When they didn't help I tried making the first OnFill item Send AddComboItem "" "" but that didn't help either. That cWebColumnCombo entry must allow blank to be a valid entry to allow for non-mapped csv fields.
Any suggestions would be most appreciated!

Device screen orientation lock

bluelight20 — Thu, 20 Aug 2026 23:03:49 GMT

Hi All,

Just curious if anyone has come across this issue with screen orientations with the webapp?

Our user has the device screen orientation locked to portrait however they are saying that the webapp still rotates. Our webapp is saved on their device as an icon (I believe this is called PWA?) if that makes a difference.

Could this be a device issue or webapp issue?

In the manifest.json file, the orientation is set to any (ie. "orientation": "any"). I believe you can set this to lock as Portrait or Landscape but I would say that that is the last resort as we still want to support both orientations.

Thanks in advance team,

cWebFileUploadButton Help

Chris Spencer — Thu, 20 Aug 2026 09:29:50 GMT

The cWebFileUploadButton Help shows an example of hiding the upload button using pbVisible=False and triggering selectFiles
from another control using ClientAction.

However, doing this results in a Server Action Security Check Error
when DoStartUpload is called because the upload control is not visible.

The example also needs:

Set pbNoAccessibilityCheck to True

Adding this to the Help example would save me head scratching.

Get Field_Current_Value of oCedulasn_DD Field cedulasn.Cedula to sCedula

Edgar H. Pe�a C. — Wed, 19 Aug 2026 23:31:04 GMT

Hi all:

df20.1 � I have two related tables, B -->A (B relates to A). I need to display them in a `cWebModalDialog` containing a `cWebPromptList`. I want the child records (B) to appear in a `cWebList` below whenever I change the parent item (A).
Even though they are related, the child records (B) do not refresh.
I decided to set table B to `pbDataAware False` and `peDbGridType gtManual` (using `OnManualLoadData`) and refresh the data when the parent changes.

Code:

Procedure OnManualLoadData tWebRow[] ByRef aTheRows String ByRef sCurrentRowID

                             Integer iNum iX iAnoTarea   

                             String sTipoU  sEmpresa sValor sAntes sCedula

                             Handle hCedulaMail

                             Forward Send OnManualLoadData (&aTheRows) (&sCurrentRowID) 

                             Move -1 to  iNum     

                             Number nCedula    

                             WebGet pgiAnoTarea    of oWebApp to iAnoTarea

                             WebGet pgsEmpresa    of oWebApp to sEmpresa

         

                             Get Field_Current_Value  of oCedulasn_DD Field cedulasn.Cedula to sCedula

Get Field_Current_Value of oCedulasn_DD Field cedulasn.Cedula to sCedula
It is NOT reading the customer ID value.

Hi guys:

I'm changing my development PC. After installing df20.1 and migrating my workspaces, the web order applications work fine. However, when I run my web application, it freezes upon launch in the browser, and in the developer tools, it appears as shown in the image. The FAVICON.ICO file is in the AppHTML folder.

Any suggestions?

WebFloatingPanel - pbScroll can't make it work

Samuel Pizarro — Fri, 14 Aug 2026 13:44:11 GMT

Mobile app, small screen.

WebFloating panel height set to a fixed value , like 300 or 400.
pbScroll set to True.

Controls inside the panel goes bigger than the panel height on purpose. We need to have that amount of controls.
I was expecting the vertical scroll bar to appear , per doc it should happen, and it does for regular views, but not happening on floating panels.

before someone asks, mobile virtual keyboards. there are input controls that get's hidden by the virtual keyboard, and user can't type on them, or see what they are typing.

our views has a bottom webspace control with a fixed height big enough to match the virtual keyboard space, this way the user can scroll the view to see all controls while the keyboard is in the screen.

First noticed in Df 19.1 but issue still happens on DF 25.0 just tested there. No scroll bars ..

This is a big issue for us..

FloatingPanel_pbScroll_issue.png

The selected div represent the panel, set with a fixed height of 350.
As you can see, the inner controls goes beyond that. I was expecting the scroll to appear.

Any Alternative ? I am missing something to set ?

The code is :

Code:

        Object oWebButton1 is a cWebButton

            Set piColumnSpan to 8

            Set psCaption to "panel"

            Set piColumnIndex to 0

        

            Procedure OnClick

                Send Show of oWebFloatingPanel1

            End_Procedure

        End_Object





        Object oWebFloatingPanel1 is a cWebFloatingPanel

            Set piColumnCount to 12

            Set piWidth to 350

            Set piTop to 20

            Set piLeft to 20

            Set psCssClass to "Shadow"

            Set piHeight to 350

            Set phoFloatByControl to oWebButton1

            Set piMinHeight to 300





            Object oWebHtmlBox1 is a cWebHtmlBox

                Set piColumnSpan to 0

                Set psHtml to "HTML Box 1"

                Set piHeight to 100

                Set pbShowBorder to True

            End_Object





            Object oWebForm1 is a cWebForm

                Set piColumnSpan to 0

                Set psLabel to "form"

            End_Object





            Object oWebCheckbox1 is a cWebCheckbox

                Set piColumnSpan to 0

                Set psCaption to "checkbox"

            End_Object





            Object oWebForm2 is a cWebForm

                Set piColumnSpan to 0

                Set psLabel to "form"

            End_Object





            Object oWebButton2 is a cWebButton

                Set piColumnSpan to 0

                Set psCaption to "hide"

            

                Procedure OnClick

                    Send hide

                End_Procedure

            End_Object





            Object oWebHtmlBox2 is a cWebHtmlBox

                Set piColumnSpan to 0

                Set psHtml to "HTML Box 2"

                Set piHeight to 250

                Set pbShowBorder to True

            End_Object





            

        End_Object

DAW, any assistance would be very welcome.. A hotfix, even better..

DF 25: Custom Control - Broke WebAppDesigner

Samuel Pizarro — Thu, 13 Aug 2026 01:12:40 GMT

Creating a new webcontrol. It works fine at runtime. no js console error when page is loaded or when the control is executed.

But it broke webDesigner somehow.. But I can't say what or why.

Code:

JavaScript error: Cannot read properties of null (reading '_oDFDomH')

If I remove my control Object from the webpage, the webdesigner loads fine.

Stop button double click

HenryEgal — Wed, 12 Aug 2026 15:20:13 GMT

Hi there,
I need to stop a double click from happening on a cWebButton. I am using Dataflex 20.0 for this webapp.

I had thought using the SetActionMode in the Procedure OnLoad handled that.
I cannot get it to happen every time, but occasionally it allows the double click and all calls in the button happen two times.
I am moving my pbEnabled to the top of onClick, but really wanted to know if SetActionMode should have handled this.

Code:

            Object oCreateAttend is a cWebButton

                Set psCaption to "Create Attendance"

                

                Procedure OnLoad

                    Forward Send OnLoad                                

                    Send SetActionMode (RefProc(OnClick)) scModeProgress "Please wait..."

                End_Procedure

    

                Procedure OnClick

                    Integer iCreate

                    Forward Send OnClick

                    Get Please_Make_Sure_All_Filled_In_For_Services 1 to iCreate

                    If (iCreate = 0) Begin

                        WebSet pbEnabled of oCreateAttend to False

                        tTicketProcess lTicketProcess

                        WebSet ptTicketProcess of oMultipleAttendance to lTicketProcess

                        Send Create_Multiple_Attendance_Web

                    End

                                                    

                End_Procedure

            End_Object

Thank you!
