gridview从绑定字段获取数据 [英] gridview getting data from bound field

问题描述

你好程序员，在这里得到一个小问题。如您所见，我在网格视图上获取数据。我的问题是如何获取绑定字段的数据？请先生帮帮我

以下是基于文本框标签获取的代码，但我无法进入绑定字段。抱歉我的英语

 Dim gvCourse As GridView = DirectCast（sender，GridView）
'获取存储在文本框中的值
 Dim strOrderID As String = DirectCast（gvCourse.Rows（e.RowIndex）.FindControl（lblOrderID），Label）.Text 
 Dim strFreight As String = DirectCast（gvCourse.Rows（e.RowIndex）.FindControl（txtFreight）， TextBox）.Text 
 Dim strShipperName As String = DirectCast（gvCourse.Rows（e.RowIndex）.FindControl（txtShipperName），TextBox）.Text 

谢谢

你好，



看到这个样本：



in clien t code sample：

< Columns> 
< asp：templatefield headerstyle-horizo​​ntalalign =  中心 headertext =  查看 >  
< itemtemplate> ; 
< asp：linkbutton id =   viewdata runat =   server text =  查看 >  
 OnClick =   viewdata_Click >  
 < /   asp：linkbutton  >  
 < /   itemtemplate  >  
< asp：boundfield datafield =   OrderId headertext =  订单ID /> 
< asp：boundfield datafield =  运费 headertext =  运费 /> 
< asp：boundfield datafield =   ShipperName headertext =  托运人姓名 /> 
 < /  列 >  
 < /   asp：templatefield   >  

样本背后的代码：

受保护的子viewdata_Click（发件人为对象，e为EventArgs）
 Dim viewdata As LinkBut​​ton = TryCast（sender，LinkBut​​ton）
 Dim row As GridViewRow = DirectCast（viewdata.NamingContainer，GridViewRow）
 '  row.Cells（0）是链接视图按钮.. 。
 Dim strOrderID As String = row.Cells（1）.Text.Trim（）
 Dim strFreight As String = row.Cells（2）.Text.Trim（）
 Dim strShipperName As String = row.Cells（3）.Text.Trim（）
 End Sub  

希望这可以帮助...

Hi,

See this sample:

In client code sample:

 <Columns>
    <asp:templatefield headerstyle-horizontalalign="Center" headertext="View">
      <itemtemplate>
         <asp:linkbutton id="viewdata" runat="server" text="View">
         OnClick="viewdata_Click">
         </asp:linkbutton>
      </itemtemplate>
      <asp:boundfield datafield="OrderId" headertext="Order Id" />
      <asp:boundfield datafield="Freight" headertext="Freight" />
      <asp:boundfield datafield="ShipperName" headertext="Shipper Name" />
 </Columns>
</asp:templatefield>

In code behind sample:

Protected Sub viewdata_Click(sender As Object, e As EventArgs)
    Dim viewdata As LinkButton = TryCast(sender, LinkButton)
    Dim row As GridViewRow = DirectCast(viewdata.NamingContainer, GridViewRow)
    ' row.Cells(0) is the link view button...
    Dim strOrderID As String = row.Cells(1).Text.Trim()
    Dim strFreight As String = row.Cells(2).Text.Trim()
    Dim strShipperName As String = row.Cells(3).Text.Trim()    
End Sub

Hope this could help...
