C＃如何将datagridview的currentrow复制到单个datarow？ [英] C# how to copy datagridview's currentrow to single datarow ?

问题描述

 DataRow dr; 
 dr =（（dgv.DataSource） as  DataTable）。行[dgv.CurrentRow.Index]; 

dgv是在winform上预定义的DataGridView。

dr总是单身。



我尝试了什么：



找到上面的代码。

但它不能正常工作。因为'CurrentRow.Index'没有与'DataTable的索引'相匹配。

我认为将DataGridViewRow复制到DataRow是最简单的方法。这是不可能的？



尝试这个的原因是当更改dgv时更新到/从数据库中删除。来自本地dgv的远程DB CRUD的任何其他更好的解决方案都应该很棒。



提前谢谢。

解决方案

< blockquote>使用CurrentRow项及它的DataBoundItem属性：对我来说，它返回一个DataRowView，它允许我访问Row本身：

 DataRowView drv = myDataGridView.CurrentRow.DataBoundItem as DataRowView ; 
 if（drv！= null）
 {
 DataRow dr = drv.Row; 
} 
 

DataRow dr;
dr = ((dgv.DataSource) as DataTable).Rows[dgv.CurrentRow.Index];

dgv is DataGridView predefined on winform.
dr is single always.

What I have tried:

Above code was found.
But it doesn't work right. Because 'CurrentRow.Index' is not macthed to 'DataTable's Index'.
I think to copy DataGridViewRow to DataRow is simplest way. Is it impossible?

Reason trying this is for Update to/Delete from database when dgv is changed. Any other better solution for remote DB CRUD from local dgv should be great.

Thanks in advance.

解决方案

Use the CurrentRow item and it's DataBoundItem property: for me, it returns a DataRowView which lets me access the Row itself:

DataRowView drv = myDataGridView.CurrentRow.DataBoundItem as DataRowView;
if (drv != null)
    {
    DataRow dr = drv.Row;
    }
