【问题描述】：

我有一个嵌套的 gridview，我想获取第一个 gridview 的值并将其分配给按钮的 commandArgument。有人可以建议如何做到这一点

正如您将在下面的代码中看到的那样，我已经使用以下代码获取行索引： " Text="保存更改" />

我需要的是 DataField="name"

查看下面的完整代码。

        <script language="javascript" type="text/javascript">
            function divexpandcollapse(divname) {
                var div = document.getElementById(divname);
                var img = document.getElementById('img' + divname);
                if (div.style.display == "none") {
                    div.style.display = "block"; img.src = "Images/Icons/minus.jpg";
                } else { div.style.display = "none"; img.src = "Images/Icons/plus.jpg"; }
            }</script>
        <asp:DropDownList ID="DateSelection" runat="server" AutoPostBack="True" Height="21px"
            Width="134px">
        </asp:DropDownList>
        <asp:GridView ID="GV_SL" runat="server" OnRowDataBound="gvUserInfo_RowDataBound"
            OnRowCommand="GV_SL_RowCommand" AutoGenerateColumns="False" 
            DataSourceID="SQL_Weekly" AllowSorting="True">
            <Columns>
                <asp:TemplateField ItemStyle-Width="50px">
                    <ItemTemplate>

                            <img id="imgdiv<%# Eval("name") %>" width="15px" border="0" src="Images/Icons/plus.jpg" /></a></ItemTemplate>
                    <ItemStyle Width="40px" />

我用 VB 代码对问题进行了排序。如果它对某人有帮助，请参见下文

Protected Sub GV_SL_RowCommand(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs)
    If (e.CommandName = "AddText") Then
        ' Retrieve the row index stored in the CommandArgument property.
        Dim index As Integer = Convert.ToInt32(e.CommandArgument)

        ' Retrieve the row that contains the button 
        ' from the Rows collection.
        Dim row As GridViewRow = GV_SL.Rows(index)
        Dim GroupName As String = GV_SL.Rows(index).Cells(1).Text

        'Rest of the code here

    End If
End Sub
