如何根据ASP.NET中的checkBox访问GridView行的值计算器

Question

嗨，我有一个GridView，具有多行和多列。我也在网格视图中添加了一个复选框。

但是现在我遇到了访问其checkBox（es）被选中的特定行的值的麻烦。

因为按下按钮，我想要将一列的值从未注册改为注册。

另一个按钮应该将检查行的帐户ID转发到另一个页面，其中输入的所有细节将被输出。

有谁知道该怎么做？

这里的代码段我使用：

提斯是GridView控件的代码和按钮：

<asp:GridView ID="GridView1" runat="server" CellPadding="4" ForeColor="#333333" 
     GridLines="None" Width="1500px"> 
     <Columns> 

        <asp:TemplateField > 
         <ItemTemplate> 
          <asp:CheckBox ID="myCheckBox" runat="server" /> 
         </ItemTemplate> 
        </asp:TemplateField> 

       </Columns> 
     <AlternatingRowStyle BackColor="White" /> 
     <EditRowStyle BackColor="#2461BF" /> 
     <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" /> 
     <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" /> 
     <PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" /> 
     <RowStyle BackColor="#EFF3FB" /> 
     <SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" /> 
     <SortedAscendingCellStyle BackColor="#F5F7FB" /> 
     <SortedAscendingHeaderStyle BackColor="#6D95E1" /> 
     <SortedDescendingCellStyle BackColor="#E9EBEF" /> 
     <SortedDescendingHeaderStyle BackColor="#4870BE" /> 
    </asp:GridView> 


    <asp:Button ID="DetailsBtn" runat="server" Text="See Details" /> 
    &nbsp; &nbsp; &nbsp; &nbsp; 
    <asp:Button ID="RegBtn" runat="server" Text="Mark Registered" /> 

这里是填充在GridView

Try 
     myconn.Open() 
     Dim sqlstring As String = "SELECT a.account_id AS 'No', a.accountid_number .BLA BLA BLA" 
     Dim smd As MySqlCommand 
     smd = New MySqlCommand(sqlstring, myconn) 
     smd.CommandType = CommandType.Text 

     Dim da As New MySqlDataAdapter(smd) 
     Dim cb As New MySqlCommandBuilder(da) 
     Dim ds As New DataSet() 
     da.Fill(ds) 

     GridView1.DataSource = ds.Tables(0) 
     GridView1.DataBind() 

     myconn.Close() 
    Catch ex As Exception 
     'System.Diagnostics.Debug.WriteLine(ex.ToString()) 
     Dim exmess As String = "alert('" & ex.Message.ToString() & "')" 
     Page.ClientScript.RegisterStartupScript(Me.GetType(), "ErrorAlert", exmess, True) 
     myconn.Close() 
    End Try 

的代码我应该怎么做这里的按钮？

Protected Sub RegBtn_Click(ByVal sender As Object, ByVal e As EventArgs) Handles RegBtn.Click 

End Sub

要查找的GridView检查行：

foreach (DataGridViewRow row in GridView1.Rows) 
{ 
Checkbox cbox = (Checkbox)row.FindControl("myCheckBox"); 
if(cbox.Checked) 
{ 
    // do your stuff ... 
} 
else 
{ // do your other stuff ... } 
}
