Hi

As you can see there are two links in the grd (Product and Vendor)
How can i detect in the click event which one is clicked and whats the value?

Hi

I don't understand what you mean

if both columns have Formatter = gcfLinkClick you should have 2 events: Col[i].FormatOptionsLinkClick.OnClick

Hi

Now i do understand your question.

1- if You set Col.FormatOptionsLinkClick.SelectRow=True, you can use Grid.JQGridOptions.SelRow

2- Has you can see in the inspector, OnClick has the arguments = 'rowid,cellvalue'

You can add a OnClick.BrowserParam and use rowid or cellvalue as BrowserScript, or simply setting OnClick.SendAllArguments=True, then you can acess trough the AParams in the event handler.

Hi

because this is generic code for a gridform where i do not know which columns will be selectable we have this code

Code: Select all

  for i := 0 to grid.JQGridOptions.ColModel.Count -1 do
  begin
    if (grid.JQGridOptions.ColModel[i].Formatter = gcfLinkClick) then
    begin
      grid.JQGridOptions.ColModel[i].FormatOptionsLinkClick.OnCLick.SendAllArguments := True;
      grid.JQGridOptions.ColModel[i].FormatOptionsLinkClick.SelectRow := True;
      grid.JQGridOptions.ColModel[i].FormatOptionsLinkClick.OnClick.OnEvent :=                              gridJQGridOptionsColModel0FormatOptionsClick;
    end;
  end;

The Aparms in the procedure TFormAdminReportOverview.gridJQGridOptionsColModel0FormatOptionsClick(
contains this values (an example):

Code: Select all

GRID_SELROW=7
IW_TrackID_=9
IW_SessionID_=0vfy7on1x14v61169d1o30vriu8r
callback=GRID.DoAjaxRequest
ajaxevent=JQGridOptions.ColModel.Items[0].FormatOptions.OnClick
rowid=7
cellvalue=Limited Function / Open
ComponentName=grid


So i now the cellValue but i also need to know the column name to see what the value is (A vendor , A Product?)

How to get this information?

I already See:

ajaxevent=JQGridOptions.ColModel.Items[0].FormatOptions.OnClick

It contains the colModel.Items[x]!!!

Hi

The Sender: TObject parameter in the event handler, is always the owner of the event

So, for

FormatOptionsLinkClick.OnClick

the Sender will be

procedure TIWForm1.LinkClick(Sender: TObject; AParams: TStringList);
var
FormatOptions: TIWCGJQGridFormatOptionsLinkClick;
begin
FormatOptions:= Sender as TIWCGJQGridFormatOptionsLinkClick;
FormatOptions.Col.Name; // This is the column
end;
