DbGrid Pagingbar New ComboBox - Clear/Load/Read - How ?


Recommended Posts

I have added a new ComboBox to a DbGrid PagingBar and I want to in code at runtime to be able to:-

1) Clear ComboBox Items
2) Add Multiple ComboBox New Items
3) Read Selected item in Items(ComboBox) via AjaxEvent (_PurchaserItems_)

The problem is referencing and adjusting the ComboBox ?

My code fragments:-

...

      '    {'#13#10 +
      '      xtype: '#39'tbseparator'#39#13#10 +
      '    },'#13#10 +
      '    {'#13#10 +
      '      xtype: '#39'combobox'#39','#13#10 +
      '      name: '#39'Items'#39','#13#10 + // guess, compiles, no crash
      '      width: 300,'#13#10 +
      '      height: 24,'#13#10 +
      '      tooltip: '#39'Items'#39','#13#10 +
      '      handler: function() '#13#10 +
      '      {'#13#10 +
      '        ajaxRequest(sender, '#39'_PurchaserItems_'#39', []); '#13#10 +
      '      }  '#13#10 +
      '    },'#13#10 +
      '    {'#13#10 +
      '      xtype: '#39'tbseparator'#39#13#10 +
      '    },'#13#10 +


...

procedure TfInvoice.dbGridInvoiceAjaxEvent(Sender: TComponent; EventName: string; Params: TUniStrings);
begin

  //////////////////////////////////////////////////////////////////////////////
  if EventName = '_PurchaserItems_' then begin 
    // Do My Thing
  end;

...

Thanks in advance

I need to re populate xtype: combobox "Items" outside of pagingbar javascript based on other ajax events.

Event A
"Items".Clear;
"Items".Add
"Items".Add
"Items".Add

Event B
"Items".Clear;
"Items".Add
"Items".Add
"Items".Add

Event C
"Items".Clear;
"Items".Add
"Items".Add
"Items".Add

Event D
I need to read selected item via ajax event (s:= dbGridInvoice.JSInterface.JSCall('pagingBar.getComponent("Items").getValue', [False]);) or something like that.

how to ADD to combobox to paginbar using PagingBarAuxControl

For example, add as indicated here, and use the capabilities of the standard UniComboBox (you can additionally use triggers).

I have also added a control to the paging bar via PagingBarAuxControl  but would like the control to be closer to the other navigation buttons.

Is there any way to left align the control so it next to the very last control in the bar?
