从LinkBut​​ton后面的代码中获取asp网格中的当前行ID

Question

我有这样的asp网格：

<asp:GridView ID="gvDetails" runat="server" AutoGenerateColumns="false" Width="100%" ShowFooter="false" DataKeyNames="ID" Enabled="false" BorderStyle="solid" BorderWidth="1px" BorderColor="#ACA899" BackColor="#BFD3EE" CellSpacing="1" GridLines="none">
<asp:TemplateField HeaderText="ProductID" Visible="false" HeaderStyle-                  HorizontalAlign="left"  HeaderStyle-CssClass="gvheader" HeaderStyle-Font-Bold="true" ItemStyle-Width="40px" >
    <ItemTemplate>
       <asp:label runat="server" ID="lblProductID" Text='<%#eval("ProductID") %>'/>
    </ItemTemplate>
</asp:TemplateField>    
<asp:TemplateField HeaderText="" HeaderStyle-HorizontalAlign="left" HeaderStyle-CssClass="gvheader" HeaderStyle-Font-Bold="true" ItemStyle-Width="50px">
    <ItemTemplate>
       <asp:LinkButton ID="lnkbtnShowProductDetails" OnClick="lnkbtnShowProductDetails_Click" runat="server"  Enabled="true">Details</asp:LinkButton>                                                 
    </ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

在代码背后我有：

Sub lnkbtnShowProductDetails_Click(ByVal sender As Object, ByVal e As EventArgs)

End Sub

如何获取当前行的ID（datakeynames的值），我不想在这里使用命令和命令参数。

请帮助我!!

Answer 1

您可以使用以下完整解决方案。

protected void lblTicketNumber_Click(object sender, EventArgs e)
    {
        LinkButton b = (LinkButton)sender;
        GridViewRow row = (GridViewRow)b.NamingContainer;
        if (row != null)
        {
           int rowIndex = row.RowIndex;
           string key = LstViewTicket.DataKeys[rowIndex].Value.ToString();
        }

    }

Answer 2

您可以使用以下代码访问数据密钥名称

Sub lnkbtnShowProductDetails_Click(ByVal sender As Object, ByVal e As EventArgs)
   Dim lnkbtnShowProductDetails As LinkButton = DirectCast(sender, LinkButton)
   Dim gridViewRow As GridViewRow = DirectCast(lnkbtnShowProductDetails.NamingContainer, GridViewRow)
   Dim val = gv.DataKeys(gridViewRow.DataItemIndex)
   Dim key = gv.DataKeyNames(gridViewRow.DataItemIndex)
End Sub
