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

[andyhill]

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

Hi,

Sorry, can you please explain in more details what you wanted!?

And what problems are you facing?

[andyhill]

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.

Hello Andy,

You can simple  use the PagingBarAuxControl property of the grid.

Please show how to ADD to combobox to paginbar using PagingBarAuxControl then else where how to CLEAR the combobox ITEMS, and how to ADD the combobox ITEMS etc.

[andyhill]

If I use PagingBarAuxControl then there is only one provision for one object -or- can we use a panel with multiple objects ?

Also how do we left align (next to nav buttons) ?

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

Yes.

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?
