本文介绍了一个用于在包含多个复选框的网格中批量选择或取消选择所有可见行的函数。该函数可在FieldChange事件中调用，允许用户一次性选择或取消选择所有行。确保网格属性中的MultipleRow复选框被选中。

The below function is to be used on a grid with multiple check boxes. Place the code behind a FieldChange event and users will have the option to Select or Deselect grid rows all at once.

Fucntion selectAllRows(&rs As Rowset)

   Local number &i;

   Local Row &row;

   For &i = 1 To &rs.ActiveRowCount

      &row = &rs.GetRow(&i);

      /* Make sure we only select visible rows. */

      If &row.Visible = True Then

         &row.Selected = True;

      End-If;

   End-For;

end-function;

/*main line*/

Local Rowset &rs;

&rs = GetLevel0()(1).GetRowset(Scroll.scroll_table);

/*Call Function*/

selectAllRows(&rs);

The same code would work for multiple check boxes "Deselect All", just change the name of the function and line &row.Selected = True; to &row.Selected = False;

Make sure the Multiple Row (Check Box) is checked on the grid properties.
