给gdv_pro.ActiveFilterString赋值就能直接控制DataGrid过滤

gdv_pro.ActiveFilterString语法：

最简单方式：gdv_pro.ActiveFilterString =" [列名] = '值' ";

或: gdv_pro.ActiveFilterString =" [列名] in ('值1','值2','值3') ";

或 gdv_pro.ActiveFilterString =" [列名] =1 And/Or [列名] =2 ";

清除过滤条件用：gdv_pro.ActiveFilter.Clear();

此外，可设置ShowFilterPanelMode=Never;禁用控件底端出现的过滤条件显示面板
