How to determine if dbTreeGrid which row selected TreeKeyFields or Node (Column) field?

[fraxzi]

Hi Everyone,

When I double-click the rows in dbtreegrid, I need to know if the selected row is the TreeKeyField or the Clild node.

How to know?

 

Thanks,

Frances

Hi Sherzod,

Based on the above

if "Row.childNodes = 0" then
    ShowMessage('clicked');

I want to click on the child node and do something.

I do this:

function cellclick(sender, td, cellIndex, record, tr, rowIndex, e, eOpts)
{
    if (!record.hasChildNodes()) {
        ajaxRequest(sender, 'nodeclicked', {value: b}, false);
    }
}

and this:

procedure TLogs.dbGridPrjsAjaxEvent(Sender: TComponent; EventName: string; Params: TUniStrings);
begin
  if EventName = 'nodeclicked' then
  begin
    ShowToast('node clicked!');
  end;
end;

but not working.. i know I did something not right.

Try replace sender to this:

ajaxRequest(this,

Eureka!  It works!! 🤩

Thanks much!

Oh, one more thing.. How can I pass the cell value to ajaxRequest and get it?

ajaxRequest(this, 'nodeclicked', {value: record.data[cellIndex]}, false);

procedure TMainForm.UniDBTreeGrid1AjaxEvent(Sender: TComponent;
  EventName: string; Params: TUniStrings);
begin
  //
  //..
  // Params.Values['value']
end;
