用空行填充DataGridview [英] Fill DataGridview with empty rows

问题描述

嗨...
我在Windows窗体中有一个datagridview.即根据组合框中的选定值填充数据库中的数据.对于某些选定的项目，在数据库中有记录.对于一些没有记录.那时我需要保持一个固定大小的datagridview，其中没有任何记录(最少10条记录).如果记录数小于10，那么我需要用空行填充它以达到10的计数.有没有办法做到这一点.如果是，请帮助我..我试图将null值行添加到grid-view的数据源中.

Hi...
I have one datagridview in my windows form. That is filling data from database based on selected value in the combo-box. For some selected item there is record in the database. for some there is no records. At that time i need to maintain a fixed size datagridview with no records filled in it(minimum 10 record). if the number of record is less than 10 then i need to fill it with null rows to achieve the count of 10. Is there any way to do this. If yes please help me.. i tried to add null value row to the data-source of grid-view. but it causing some problems while processing the grid-view values.

推荐答案

从数据库中获取数据之后.遍历每个组合选择的数据，如果计数少于10，则添加，然后将更多对象添加到列表中，以达到计数10.
