UniDBgrid - how simulate doubleclick on a grid row (client code or JsCode) pressing a UniButton

[Stemon63]

Hi, I need to simulate doubleclick press for select a row in UniDbgrid, but from a UniButton, so I need help on the JS code to inject.
Thanks in advance!

Hello,

What action happens in a double click in general?

[Stemon63]

HI,
for "security" reasons (I don't know my users), I have inhibited the repeated calls to the server that occur when the user continuously scrolls through the records ("return false" in Mygrid.ClientEvents.ExtEvents.Values['selectionchange ']).
When I double-click on the record, UNigui calls the server and synchronizes the current record so I can show the detail form.
I need to perform the same operation from a UniButton.
I need to call doubleclick event on the client from a Unibutton.
Thanks

Hi Sherzod, 
thanks, I have already tested this solution.  But that solution don't works for me for this scenario. It permits to call the server for every scroll (also non continuous).
I want that dataset records on server are syncronized only with doubleclick. Ant this already works optimal because there are no calls  on grid scroll, but server is updated on doubleclick.. 
I need simply a way for "force" pressing doubleclick on the grid from JS (called from a button or an action) 🙂 
Thanks a lot

Can you please provide your grid configuration?

Hi Sherzod,
is a standard TUnidbGrid;




object gridLista: TUniDBGrid
  Left = 16
  Top = 16
  Width = 761
  Height = 307
  Hint = ''
  ClientEvents.ExtEvents.Strings = (
    
      'selectionchange=function selectionchange(sender, selected, eOpts' +
      ')'#13#10'{'#13#10'  return false;'#13#10'}')
  PagingBarAuxControl = lblTotRecord
  DataSource = D_Lista
  Options = [dgTitles, dgIndicator, dgColumnResize, dgColLines, dgRowLines, dgRowSelect, dgConfirmDelete, dgAutoRefreshRow]
  ReadOnly = True
  LoadMask.Message = 'Caricamento Dati...'
  LayoutConfig.Region = 'center'
  BorderStyle = ubsFrameLowered
  TrackOver = False
  TabOrder = 1
  PreventWrap = True
  Exporter.Enabled = True
  OnAjaxEvent = gridListaAjaxEvent
  OnColumnSort = gridListaColumnSort
  OnDblClick = gridListaDblClick
  OnClearFilters = gridListaClearFilters
  OnColumnFilter = gridListaColumnFilter
  Columns = <
    item
        FieldName = 'id'
      Title.Caption = 'ID'
      Width = 47
      Sortable = True
      Menu.MenuEnabled = False
      Menu.ColumnHideable = False
    end
    item
       FieldName = 'com_comune'
      Title.Caption = 'Comune'
      Width = 304
      Sortable = True
      Menu.MenuEnabled = False
      Menu.ColumnHideable = False
    end
    item
      Flex = 1
      FieldName = 'com_prov'
      Title.Caption = 'Prov'
      Width = 67
       Sortable = True
      Menu.MenuEnabled = False
      Menu.ColumnHideable = False
    end>
end

Sorry, I doubt it, as you say. Could you make  a simple testcase for this case?

[Stemon63]

I should send you a simple form with a button to a UniDbgrid...
What I want to achieve is to double-click on the grid, not with the mouse, but through the code under the pressure of a button (or an action). So I get the server to synchronize again on the current grid record.
No possible solution?

Perhaps this won't work...

[Stemon63]

Or a javascript command that tells the server to synchronize the position of the current record in the dataset...

You can analyze the selectionchange event (params) and try using ajaxRequest.

[Stemon63]

So no way to simulate (or perform) a double click from a button (or any other action on the grid)?

It is possible, but in your case, you suspend the selectionchange event, right?

[Stemon63]

Yes, Sherzod.
(we could have users who work for the competition, who would continue endlessly scrolling the grids while holding down the up and down keys).
I want to align the server only on single actions, and double click (or enter) already works perfectly.
I just need the same key action from buttons (on mobile it is mandatory). But selectionchange must be disabled. I clearly need this to prevent users from crashing the system simply by holding down the arrow keys.

Hi Sherzod, any way for solve my traffic problem (which is useful to everyone)?
This is all that's missing to be able to distribute my application 🙂
Thanks
