如何向未绑定的DataGridView添加一行？ [英] How to add a row to a unbound DataGridView?

问题描述

我在C＃中有一个 DataGridView ，我想以程序化方式添加行。没有数据绑定到网格，但是当我调用 dataGrid.Rows.Add（）; 它会引发一个 System.InvalidOperationException 。

I have a DataGridView in C# and I want to add rows in a programmatic way. There is no data bound to the grid but when I call dataGrid.Rows.Add(); it throws a System.InvalidOperationException.

我浏览了互联网，只有拥有数据的人才发现这个问题。我想让网格从代码完全控制。

I looked all over the internet and I only found this problem for people who have data bound to it. I want the grid to be controlled completely from the code.

有人可以帮助我吗？

不确定是否有所作为，但我使用.Net框架3.5。

Not sure if it makes a difference but I use .Net framework 3.5.

推荐答案

我通常会用其他人提供的答案这不是这样，因为答案并不真正有用。

I usually go with answers provided by other people but this is not the case since the answers aren't really helpful.

正如我所说dataGridView1.Rows.Add（）;抛出异常，AddRange也是如此。

我做了很多检查后发现了答案。显然，如果我添加了很多行/秒（约30），则不喜欢它。

我通过网络接收我的行，所以我创建了一个行池，每隔一秒我更新了datagridview。

这似乎已经修复了没有显示的行和异常。

As I stated "dataGridView1.Rows.Add();" threw an exception and so did AddRange.
I found out the answer after doing a lot of checks. Apparently .Net does not like it if I add a lot of rows/second (about 30).
I receive my rows via networking so I created a pool of rows and every second I updated the rows from the datagridview.
This seems to have fixed both the rows not showing up and the exceptions.
