推荐答案

这里讨论并解决了类似的问题：这里 [ ^ ]



总的来说，它说：

根据例外情况，您似乎尝试读取已经删除的行。



所以我认为应该添加一些逻辑来避免这种情况。

1.检查目标行是否存在;

2.当它存在时，做一些事情。

Here similar issue discussed and resolved: here[^]

Overall, it says:
According to the exception, it seems that you try to read a row which has been deleted already.

So I think some logic should be added to avoid this.
1. check if the target row is existed ;
2. When it is existed, do something.

我的代码也出现了同样的错误

我是如何使用linq将datagridview与表绑定..



我将我的代码更改为

I was also getting the same error with my code

This row has been removed from a table and does not have any data. BeginEdit() will allow creation of new data in this row.

How ever i was binding datagridview with table using linq..

I change my code to

<pre lang="c#">
var qry = from si in tempdset.ItemSuppliers.AsEnumerable()
          where si.itemid == Convert.ToInt32(cmbSuppItem.SelectedValue.ToString())
          select si;
DataGridview1.DataSource = qry.AsDataView();

来自

from

<pre><pre lang="c#">
var qry = from si in tempdset.ItemSuppliers.AsEnumerable()
          where si.itemid == Convert.ToInt32(cmbSuppItem.SelectedValue.ToString())
          select si;
DataGridview1.DataSource = qry.ToList();
</pre></pre>

其中，

temdset是一个DataSet，而ItemSuppliers是表名。

where,
temdset is a DataSet and ItemSuppliers is table name.
