为什么delphi下DBGrid的Column能改长度，但是delphi7下DBGrid的Column不能改长度？

zhbruce 2003-09-29 10:36:56

在未编译状态下，我设好了Column的长度，编译时，Column就变得很长。与原来设好的不符。
这种情况只出现在delphi7下，delphi6没有这个问题！
请问如何解决这个问题？

dbgrideh 实现有条件合并单元格的例子内含修改的dbgrideh 4.2控件

Delphi DBGridEhColSelect设置DBGridEh列显示

Delphi功能丰富的数据库浏览器程序源代码，让DBGrid组件的标题能进行对DBGrid内的数据对行排序，把DBGrid组件内的数据导出到HTML文件，让DBGrid1控件能自动调节字段的宽度（数据网格自动适应宽度），用法:用DBGrid的DBGrid1DrawColumnCell事件调用DBGridRecordSize(Column); 然后调用DBGridAutoSize(DBGrid1)即可，用法:DBGridToHtml(DBGrid1,Date,Table);DBGrid1为DBGrid控件,Date为一个TSrings的变量,Table为HTML文件的标题。导出到文件:Date.SaveToFile(FileName); FileName为要导出文件的路径及文件名。。。

Ehlib 是著名的数据库连接控制，版本为5.0.13，DBgrid增强VCL控件；支持多表头，多固定列，按表头排序，支持合计列，并支持直接打印。可以和PB的ataWindow媲美。本版本含完整源代码，支持以下 IDE： Delphi 5,6,7,2005 C++Builder 5,6 BDS 2006 (Delphi 2006, C++Builder 2006) Delphi 2007 RAD Studio 2009 (Delphi 2009, C++Builder 2009) Embarcadero RAD Studio 2010 (Delphi 2010, C++Builder 2010) 本人已在Delphi 2010中运行通过，在本人编制的进销存软件中应用完全正常。注：Delphi2010里面安装不要修改bpl文件的输出路径，采用默认值，否则安装难以成功。 Version 5.0的改进： + At design-time grid can show such components as DataSource, DataSet, DataDriver in its the bottom left part. These components can be selected in object inspector by mouse clicking. It allows to find quickly and select components which is connected to the grid. + New mode - RowPanel. In this mode grid allows to show out cells of record one under another and change height of every cell separately. + Grid can have special panel of detail information for record. It is allowed to put any control from component palette on this panel. At run time, panel is hidden and user can open it by pressing on a '+' sign which is shown at the begining of every row. + Grid can scroll data smoothly and by small steps of one pixel size. Grid can scroll data smoothly vertically and horizontally. + Hot track. Grid can highlight a cell or a row under mouse cursor. + Grid can show vertical line in gradient mode between data rows and bottom part of the grid. + In mode Column.AlwaysShowEditButton grid shows EditButtons in shadow mode. It doesn't irritate eyes by big amount of edit buttons in the grid. + New property EditButtonsShowOptions is added in the Grid of type TEditButtonsShowOptionsEh. TEditButtonsShowOptionsEh = set of (sebShowOnlyForCurCellEh, sebShowOnlyForCurRowEh, sebShowOnlyWhenGridActiveEh, sebShowOnlyWhenDataEditingEh); When Column.AlwaysShowEditButton is True, this property allows to customize, in which cases it is need to show EditButtons. : See detail information
