[Why in Windowless ... is the OnAfterShow event called 2 times?]

in the example "uniGUI \ Demos \Desktop\Windowless"

UniServerModule.MainFormDisplayMode = mfPage

if I add to the source

MainForm.OnAfterShow = UniFormAfterShow

procedure TMainForm.UniFormAfterShow(Sender: TObject);
begin
  UniMemo1.Lines.Add('--- > OnAferShow');
end;

the OnAfterShow event is called 2 times.

Why?

 

[Security questions]

The problem exists ...
but you can evaluate .. before the components are created

rate this test

procedure TMainForm.UniFormCreate(Sender: TObject);
begin
  
  UniDBGrid1.Columns.Delete(2);  // before starting the data request .. the associated field will not be asked
    
  UniBitBtn1.Free; // it appears that the button is created ... but not combined with the click
  
end;
  

try and see if it's okay.

[How do I make a Panel invisible by clicking a button on the client side]

Thank you very much!!

if you liked it, give it a "Like"

Ciao.

[How do I make a Panel invisible by clicking a button on the client side]

procedure TMainForm.UniFormCreate(Sender: TObject);
begin
  UniButton1.JSInterface.JSAddListener(
     'click', 
     'function(){'+ 
        UniPanel1.JSName +'.setVisible(!'+ UniPanel1.JSName +'.isVisible())'+
     '}'
  );
end;

i think you want to create a switch between visible and invisible

[Read LocalStorage]

maybe you can use this example of mine..

I created you a generic procedure (GetLocalStorage) that shows you all the values of localStorage
 and waits to read them in UniFormAjaxEvent.

the procedure is started when the form is ready .. but you can also call it at the click of a button ..

object MainForm: TMainForm
  OnReady = UniFormReady
  OnAjaxEvent = UniFormAjaxEvent

type
  TMainForm = class(TUniForm)   

    procedure UniFormReady(Sender: TObject);
    procedure UniFormAjaxEvent(Sender: TComponent; EventName: string;
      Params: TUniStrings);
  private
    { Private declarations }
    FLKey: string;
  public
    { Public declarations }
     procedure GetLocalStorage;
  end;

procedure TMainForm.GetLocalStorage;
begin
  UniSession.AddJS(
    ' var p = [], keys = Object.keys(localStorage), i = 0, key; '+
    ' for (; key = keys[i]; i++) { p.push( key + "=" + localStorage.getItem(key)); } '+
    ' ajaxRequest(MainForm.window, "getKey", p); '
  );
end;

procedure TMainForm.UniFormReady(Sender: TObject);
begin
  FLKey:='';
  GetLocalStorage;
end;

procedure TMainForm.UniFormAjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);
begin
  if EventName = 'getKey' then
  begin
    FLKey := Params.Values['lKey'];
    UniMemo1.Text := Params.Text; // <---- read all values
  end;

I hope you find it useful ..

[Small adjustment for UniDBGrid .. (ForceStringFormat)]

19 minutes ago, Farshad Mohajeri said:

This ticket is already reviewed and replied.

Initially I asked to consider OnGetText () for cell formatting ...
later .. you created the ForceStringFormat property ..
Now I don't understand why at that point
.. there is a check on OnGetText and not on ForceStringFormat.

The right check would be to check if the Field has a DisplayFormat set ... but I can do this with an override for GetForceStringFormat.

I would like to give suggestions ...
if you don't want them ...
thanks anyway.

You should send a request to the support portal...

this is an old discourse:

http://jira.fmsoft.net/servicedesk/customer/portal/4/FSD-568

however I added this post 

... but ... give me an answer ...
I hope not to wait ... two years .. since 2018 has been reopened and I have not had an answer.

[Small adjustment for UniDBGrid .. (ForceStringFormat)]

For a better management of the string format of the field .. I ask you if it is possible to have this modification

function TUniCustomDBGrid.GetCellData(const ColNo: Integer; var HasAttr: Boolean): TUniCellRecord;
...
     else
      begin
//        if Assigned(AField.OnGetText) then
        if wColumn.ForceStringFormat then 
        begin
          if RawData then
            rValue := StrToJS(AField.DisplayText)
          else
            S := StrToJS(AField.DisplayText);
        end
        else
        begin

to change  " if Assigned(AField.OnGetText) then" in   " if wColumn.ForceStringFormat then " for me it's important
Grazie

In the meantime .. I put a patch like this

var
  AStart, APage, ALimit : Integer;
begin
  inherited;
  if AEventName = UNI_DATA_EVENT then
  begin
    if not (dgPersistentSelection in FOptions) then
      FBookmarks.Clear;

    if FDelayBeboreLoad and FFirstLoad then Sleep(500);
    FFirstLoad := False;

    ALimit:=AParams['limit'].AsInteger;
    if FBufferedStore.FEnabled then
    begin
      APage  :=StrToIntDef(AParams['page'].AsString, 1)-1;
      AStart := APage*ALimit;
    end
    else
      AStart := StrToIntDef(AParams['start'].AsString, -1);
    HandleData(
      AStart,
      AParams['limit'].AsInteger,

[Grid - Infinite Scroll]

I think the answer is in this discussion ...

Farshad Mohajeri said:

This is a client side exporter developed by Sencha, so it can only export the visible page.

If your grid is paged and you need to export all pages you must use a server side exporter such as FlexCell.

Also you can switch to a non-paged grid.

[check the operation of "Infinite Scroll"]

You can control?

[UniGridExcelExporter export 1 page]

in unit uniBasicGrid;
TUniGridExporter.ExportGrid 
to correct the line in

  JSConfig('filename', [FFileName + '.' + Self.FExporter.FileExtention], ExpCfgObj);

  JSConfig('fileName', [FFileName + '.' + Self.FExporter.FileExtention], ExpCfgObj);

n -> N

please .Farshad Mohajeri ... for me you can also add this code

TUniGridExporter = class(TPersistent)
  private
    function FileNameIsStored: Boolean;
    function TitleIsStored: Boolean;
    ...
  published
    ...
    property FileName: string read FFileName write SetFileName stored FileNameIsStored;
    property Title: string read FTitle write SetTitle stored TitleIsStored;
  end;

function TUniGridExporter.FileNameIsStored: Boolean;
begin
  Result := FFileName <> 'Export';
end;

function TUniGridExporter.TitleIsStored: Boolean;
begin
  Result := FTitle <> 'Exported Grid';
end;

so as not to store the two values in dfm
thank you

to be able to set it but CustomMeta?

[Set Filtering.Editor.ClearButton = false]

Ciao Sherzod

in unit uniDBGrid

procedure TUniCustomDBGridColumn.InitFilter(C: TJSObject; Fld: TField);

        (FEdit as IUniFormControl).ClearButton := True;

        TUniControlHack(FEdit).LayoutConfig.Width := '95%';

I think it's a solution is to create a property in Column.Filtering or generic .. like UseEditorClearButton stored false

if NOT UseEditorClearButton then
 (FEdit as IUniFormControl).ClearButton := True;

another block to consider a modification is the width property, I would modify the code in

if TUniControlHack(FEdit).LayoutConfig.Width='' then
  TUniControlHack(FEdit).LayoutConfig.Width := '95%';

Grazie

[Grid with Buffered Store]

Ciao Farshad Mohajeri
I thank you for the answer..

I understand ,
creating a synchronized with the server is difficult ..
in fact, I asked:

Is this difficult to implement for at least non-editable grids? 

to have a grid that displays data like the extjs example.
And I asked if anyone had tried to do it ...and I asked for help
(I didn't ask for someone to write a solution overnight )

I do not accept that there is a difficulty to overcome and it will not be solved. Then she is postponed for a year.

so no more investment is needed if you have a valid subscription

Paying the cost of UNIGUI is not the difficulty (in fact I manage 2 licenses)
.. who more than me believes in this Framework

long life to UniGUI!

But consider this:
if a customer asks me: "the application must adapt to the device"
I see your roadmap .. and I read "Responsive Layout" expected in Q1 / 2020
.. then I communicate the realization times to the customer ..
if this is not done .. before 2021 ... i have a dissatisfied customer.

 

My question remains:
has anyone tried to recreate the example of extjs .. can you help?

 

[Grid with Buffered Store]

Hi
can your attempts be published?
As we read in the buffered-store.js file:
"This particular service cannot sort on more than one field, so if grouped, it disables sorting."
I (and many) don't need it.

You need the bare minimum to view a large number of records ... this is a big problem that extj has solved with this example.

 

I thank you for your work ...
but I cannot avoid highlighting :

Long-time ago we started to develop it but because of the problems, we stopped. Buffered property comes from those days.

reading this statement is disheartening! It was expected in Q1 / 2019 now we are in Q1 / 2020. .. a year without a solution
(maybe .. it was better to write "we have not yet evaluated this point")

I have invested in you for 5 years now ... with 2 licenses ..
.. and while paying the more expensive version .. don't provide all your sources .. or our versions of the js files not minimized ..
all of us other developers with these handicaps are forced to read up on extj's publications .. or learn from those who in this forum come up with ideas they share.

and we are forced to wait do what you write
