如何将选定行从网格视图绑定到另一个网格视图

Question

我想将选定的行从 gridview 添加到另一个 gridview。有人可以帮我吗？当我尝试将 gridview 绑定到另一个 gridview 时，另一个 gridview 不会出现。

我在下面发布的 aspx 文件是关于我如何创建网格视图的。 gridview1 将从数据库表中获取其 gridview 内容。虽然cs文件是关于我将如何将选定的行从gridview1绑定到gridview2。现在的问题是当我尝试绑定行时，gridview2 没有出现，只有 gridview1 出现了。

这是我的代码：

ASPX 文件：

            GridView2.DataSource = dt;
            GridView2.DataBind();
        }
    }
}

非常感谢任何帮助。谢谢！

我真的不明白你做的乱七八糟的代码（你的问题中遗漏了太多东西）。请参阅下面的链接，这些链接将向您解释示例。

• http://www.aspsnippets.com/Articles/Transfer-Selected-Rows-from-one-GridView-to-Another-in-Asp.net.aspx
• http://www.ittutorials.in/source/aspDotnet/scf13/move-gridview-rows-from-one-gridview-to-another.aspx

更新：

dt.Rows.Add() 必须在 for 循环内，因此每次都会添加新行。

尝试更新cs文件中的以下代码

for(int i=0; i<dataRow.Table.Columns.Count; i++)
{ 
   dt.Rows.Add(GridView1.SelectedRow.Cells[i2].Text);
   i2++;
}
GridView2.DataSource = dt;
GridView2.DataBind();
