无论如何在这里发布图片？ Datagridview以另一种形式传递给Texbox [英] is there anyway to post pics in here? Datagridview passing to Texbox in another form

问题描述

在表单2中有一个搜索键，在form1中有一个datagridview



我希望将所选的值从form1的dgv传递给form2 = tb 1中的2个文本框和tb 2



如果要求2笔交易，我必须将另一个值传递给另外2个2格式的文本框


$保存前b $ b = tb 3和tb 4.



提前谢谢..

推荐答案

请参阅在表单之间传递数据 [ ^ ]。

看起来很受欢迎关于形式合作的问题。最强大的解决方案是在表单类中实现适当的接口，并传递接口引用而不是引用Form的整个实例。有关更多详细信息，请参阅我以前的解决方案：如何以两种形式复制列表框之间的所有项目 [ ^ ]。



另请参阅此处的其他解决方案讨论。如果应用程序足够简单，解决方案就像在一个表单中声明一些 internal 属性并将对一个表单的实例的引用传递给另一个表单的实例一样简单形成。对于更复杂的项目，这种违反严格封装的样式和松散耦合可能会增加代码的意外复杂性并引发错误，因此封装良好的解决方案将是优惠。

It looks like the popular question about form collaboration. The most robust solution is implementation of an appropriate interface in form class and passing the interface reference instead of reference to a "whole instance" of a Form. Please see my past solution for more detail: How to copy all the items between listboxes in two forms[^].

Please also see other solutions in this discussion. If the application is simple enough, the solution could be as simple as declaring of some internal property in one form and passing a reference to the instance of one form to the instance of another form. For more complex projects, such violation of strictly encapsulated style and loose coupling could add up the the accidental complexity of the code and invite mistakes, so the well-encapsulated solution would be preferable.
