与数据网格中的两个组合框的关系 [英] relation with two comboboxes in a datagrid

问题描述

你好，

我是编程和论坛的新手，所以请原谅我可以说的愚蠢事情的进展。



所以这里是：

我想创建一个包含工作中使用的设备列表的表单，并且我在vb 2010中使用它来获取带有列的数据网格视图（两个组合框[使用的设备] ] / [功能]和两个文本框[数量] / [Obseravtions]）。



问题是两者应该连接组合框，由第二次提出 - 下面的列表取决于dgv中第一个组合框的选择。







现在我我试了大约三个小时，但我不能。



提前感谢您的帮助。

hello,
I'm new in programming and on the forum, so excuse me for advances on the stupid things I could say.

So here it is:
I want to create a form with a list of equipment used at work, and I use it for, in vb 2010 a datagridview with columns (two combobox [Equipment used] / [Features] and two textbox [Quantity] / [Obseravtions]).

The problem is that the two should be linked combobox, proposed by the second drop-down list depends on the choice focused on the first combobox in the dgv.



and now I'm trying for about three hours, but I can not.

Thank you in advance for your help.

一个建议，不要试图一次做太多，试着接近这个订单中的问题

- 首先将项目手动插入单个组合框（您可能需要谷歌获取有关如何操作的文档）

- 然后担心关于根据另一个的值改变组合框的内容。

- 最后，将这些组合框放入datagridview。

One suggestion, don't try to do too much at once, try approaching the problem in this order
- do the manual insertion of items into a single combobox first (you may need to google for the documentation on how to do that)
- then worry about changing the content of a combobox based on the value of another one.
-Finally, put those comboboxes into a datagridview.
