Hello,

For what purpose?

[Alexandre Trevizoli]

I have an custom search form, that when user click on title of grid, they can search for that column on an edit field.

Try this approach:

1. UnimDBGrid1.ClientEvents.ExtEvents ->

function painted(sender, eOpts)
{    
    sender.getColumns().forEach( function(col){
        if (col.headerElement) {
            col.headerElement.addListener('click', function(a,b) {
                if (b.classList[0] && (b.classList[0].indexOf('x-header-el') == 0 || b.classList[0].indexOf('x-text-el') == 0)) {
                    ajaxRequest(sender, 'titleClick', {colIndx: col.getDataIndex()})
                }
            })
        }
    });
}

2. UniDBGrid1.OnAjaxEvent ->

procedure TMainmForm.UnimDBGrid1AjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);
begin
  if EventName = 'titleClick' then
    ShowMessage(Params.Values['colIndx'])

end;

                }
            })
        }
    });
}

end;

 

It's worked!
I make an simple change taking out this 

 if (b.classList[0] && (b.classList[0].indexOf('x-header-el') == 0 || b.classList[0].indexOf('x-text-el') == 0)) 

because some places that I click the listener not work, after taking out, work on every place of title.

But I tested that if I make some change on Title font color on runtime (when I click, in my original code, I change font color to Marron) listener is lost.
Could or Should I add it again after some change on grid? How?

Thanks a lot!
I think you could put this on roadmap of mobile development.
