Question

我有一个GridView（gvSummary），每行包含一个按钮。单击此按钮时，将打开一个显示第二个GridView（gvDetail）的模式窗口。从源代码中，我似乎无法引用第二个GridView。当我尝试它时会给出错误消息"The name gvDetail does not exist in the current context."

<asp:TemplateField ShowHeader="False">
    <ItemTemplate>
        <div>
            <asp:Button ID="btn_open" runat="server" OnClick="btn_open_Click" Text="Show Gridview" CssClass="openModal" CommandName="cmdDetail"/>
                <div class="modal" id="idModal">
                    <div class="container">
                        <div class="modal-header">
                            <h1>Transaction Details<a class="close-modal" href="#">&times;</a></h1>
                        </div>
                        <div class="modal-body">
                            <asp:GridView ID="gvDetail" runat="server" DataSourceID="SqlgvDetail" AutoGenerateColumns="false"
                            OnRowDataBound="gvDetail_RowDataBound" CssClass="table table-hover table-bordered" EmptyDataText="No data to display." >
                                <Columns>
                                    <asp:BoundField DataField="metalid" HeaderText="Metal ID"/>
                                    <asp:BoundField DataField="enddate" HeaderText="End Date" DataFormatString="{0:dd-MM-yyyy}" />
                                    <asp:BoundField DataField="startdate" HeaderText="Start Date" DataFormatString="{0:dd-MM-yyyy}" />
                                    <asp:BoundField DataField="clientref" HeaderText="Client Ref" />
                                    <asp:BoundField DataField="quantity" HeaderText="Quantity" DataFormatString="{0:N2}" />
                                </Columns>
                            </asp:GridView>
                        </div>
                        <div class="modal-footer">
                            <asp:Button ID="btn_close" runat="server" Text="OK" CssClass="close-modal btn-sm btn-primary"/>
                        </div>
                    </div>
                </div>
            <div class="modal-backdrop"></div>
        </div>
    </ItemTemplate>
</asp:TemplateField>

上面的TemplateField位于第一个Gridview中。有没有办法从源代码中引用这个GridView？

感谢任何帮助。

如果我理解正确，您正在尝试获取子gridview gvDetail的参考？如果是这样，我认为你可以做到这一点。您应该可以通过其父网格视图gvDetail事件找到OnROwDataBound。

protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // get the reference of child gridview
        GridView gvDetail = e.Row.FindControl("gvDetail") as GridView;
    }
}

引用位于模态窗口内的GridView - （C＃）
