New function for tADVColumnGrid (VCL and FNC)

It exists a very efficient function : GetColumnByName
property ColumnByName[AValue:string]: TGridColumnItem read GetColumnByName;

Is it possible to add a new using the tag of the column ?
Function GetColumnByTag
property ColumnByTag[AValue:Integer]: TGridColumnItem read GetColumnByTag;

working when tag > 0 (of course)

function TAdvColumnGrid.GetColumnByTag(AValue: Integer): TGridColumnItem;
var
   i: Integer;
 begin
   Result := nil;
   IF AValue > 0 THEN
   Begin
      i := 0;
      while i < Columns.Count do
      begin
        if Columns.Items[i].Tag = AValue then
        begin
          Result := Columns.Items[i];
          Break;
        end;
        inc(i);
      end;
   end;
 end;

We'll add it for the next update.
Not sure why you only allow Value > 0, a search on a negative value might be possible as well.

Thanks you

And yes you are right, negative value can be significant too
