转移选定的记录 [英] transfer selected records

问题描述

如何在VB.NET中将所选记录(使用复选框选中)从一个datagridview传输到另一个datagridview


我在第一列中有一个带复选框的Datagridview，如果有10条记录，而我在Datagridview中使用复选框仅选择了5条记录，则在按钮的单击事件上它会在第二个Datagridview中被查看

我卡住的代码:

How do i transfer selected records(selected using check box) from one datagridview to another datagridview in VB.NET


I have one Datagridview with checkbox in 1st column, if there are 10 records and I select only 5 records using checkbox in Datagridview, on the click event of button it gets viewed in 2nd Datagridview

The code where i stuck :

For j As Integer = 0 To DataGridView2.Rows.Count - 1 
    If CBool(DataGridView2.Rows(j).Cells(1).Value) = True Then 
        Dim r As Form1.DataGridView2.Rows.count
        Form1.DataGridView2.Rows(r-1).Cells(0).Value = DataGridView2.Rows(j).Cells(0).Value 
    End If 
Next

它显示了无法使用编程插入数据的异常.

It shows exception that data can not be inserted using programming.

推荐答案

在按钮click事件上，使用数据表dt = gridview1.datasource;.这将为您提供第一个gridview的数据.之后，您可以进行循环检查是否选中了特定的行.如果不这样做，请从数据表中删除该行.然后将该数据表分配给第二个gridview

希望对您有帮助.

on the button click event , take the datatable dt=gridview1.datasource; which will give you the data of first gridview. After that you can do a loop in which you can check whether a particular row is selected or not.If not than remove that row from your datatable.After that assign this datatable to your second gridview

Hope this helps you.
