如何获取单元格值以从嵌套gridview更新数据？

Question

我有2个gridview。 Gridview内部gridview。第一个gridview显示相同发票号和党名等的总和...，当我点击加号时，它会在第二个gridview中显示多个条目。我想编辑那些条目。为此我只需要我的主键值Id。所以我可以获取数据并可以更新。如何从第二个Gridview获取ID？请帮我。先谢谢你。

这是我已经知道我想要的图像。请点击这个

这是使用ASP.NET的HTML代码

Answer 1

我为此写了一个解决方案。

C＃代码：

protected void grdUpdateData_SellsEdit(object sender, GridViewCommandEventArgs e)
{
    if(e.CommandName == "Edit")
    {   
        GridView grdUpdateData = (sender as GridView);
        int index = Convert.ToInt32(e.CommandArgument);   
        GridViewRow row = grdUpdateData.Rows[index];     
        int RowId = Convert.ToInt32((row.Cells[0].FindControl("lblId") as Label).Text);
    }
}

在HTML代码中进行一些更改：

<asp:TemplateField HeaderText="ID" ItemStyle-CssClass="Hide" HeaderStyle-CssClass="Hide"> //Include CSS to hide the column instead of using Visible = "false"
    <ItemTemplate>
        <asp:Label ID="lblId" Text='<%# Eval("Id") %>' runat="server"></asp:Label>
    </ItemTemplate>
</asp:TemplateField>

CSS代码：

 <style type="text/css">
    .Hide
    {
        display: none;
    }
 </style>

希望这有帮助！
