cxgrid的过滤%x%问题【备查】

把这个文件复制到你的程序目录
\DevExpress VCL\ExpressDataController\Sources\cxLike.pas

function LikeStr(const AStr, APatternStr: string; APercent, AUnderline: Char): Boolean;
var
  vPatternStr : string;
begin
  vPatternStr := Format('%%%s%%', [APatternStr]);
  Result := Like(PChar(AStr), Length(AStr), PChar(vPatternStr),
    Length(vPatternStr), APercent, AUnderline, #0);
end;

===========

补充，在ExpressDataController\Sources中，重新编译ExpressDataController\Packages\cxDataD11.dproj后ok。
