GridView

Question

我有一个 GridView 和一个包含按钮的 TemplateField。此按钮打开一个模式 window，其中包含另一个 GridView，如下所示：

Gridview1 中的模板字段：

<asp:TemplateField>
<ItemTemplate>
    <asp:Button ID="btnOpen" runat="server" Text="Show Gridview" OnClick="btnOpen_Click" data-toggle="modal" data-target="#myModal"/>
</ItemTemplate>

模态 Window:

<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" AutoGenerateColumns="false" DataSourceID="SqlgvDetail"
                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>

GridView2 SqlDataSource:

<asp:SqlDataSource ID="SqlgvDetail" runat="server" ConnectionString="<%$ ConnectionStrings:InventoryConnectionString %>"
    SelectCommand="SELECT td.metalid , td.enddate , td.startdate , td.clientref , td.quantity FROM trxdetail td">
</asp:SqlDataSource>

现在这段代码工作正常，并按预期打开带有 SelectCommand 的模态 window。但是，我需要根据 GridView1 中的行值添加一个 where 子句。例如。 ...WHERE td.clientref = GridView1.SelectedRow.Cells[0].Text

请帮忙！

编辑：模态 Window:

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
        <div class="modal-dialog" role="document">
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                    <h4 class="modal-title" id="myModalLabel">Modal title</h4>
                </div>
                <div class="modal-body">
                    <asp:GridView ID="gvDetail" runat="server" AutoGenerateColumns="false" DataSourceID="SqlgvDetail"
                    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">
                    <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                    <button type="button" class="btn btn-primary">Save changes</button>
                </div>
            </div>
        </div>
    </div>

模态 JS:

$(document).ready(function () {
        $("#btnOpen").click(function () {
            $("#myModal").modal();
        });
    });

您实际上可以将 <asp:ControlParameter> 设置为 GridView 的 SelectedValue。我想这就是你要找的。正如文档所说：

As a further shortcut, you can directly determine the data key value of the first key field of the selected row by using the SelectedValue property.

因此，您可以将 GridView1 上的 DataKeyNames 值设置为您想在 WHERE 子句中使用的任何值。

<asp:GridView ID="GridView1" runat="server" DataKeyNames="clientref"
    ...
</asp:GridView>

然后将其设置为您的 SqlDataSource 中的控制参数。

<asp:SqlDataSource ID="SqlgvDetail" runat="server"
    ConnectionString="<%$ ConnectionStrings:InventoryConnectionString %>"
    SelectCommand="SELECT td.metalid, td.enddate, td.startdate, td.clientref , td.quantity 
                   FROM trxdetail td
                   WHERE clientref=@clientref">
    <SelectParameters>
        <asp:ControlParameter ControlID="GridView1"
            PropertyName="SelectedValue"
            Name="clientref"
            Type="Whatever type clientref is" />
    </SelectParameters>
</asp:SqlDataSource>

请记住，您需要确保 GridView1 中的行实际标记为 SelectedRow。您可以在按钮单击事件中执行此操作。

protected void btnOpen_Click(object sender, EventArgs e)
{
    // Find the index to select
    Button btnOpen = (Button)sender;
    GridViewRow row = (GridViewRow)btnOpen.NamingContainer;
    int selectedIndex = row.DataItemIndex;

    // Set the selected index of the GridView
    GridView1.SelectedIndex = selectedIndex;

    // Bind the detail GridView now that the row is selected so 
    // that its SqlDataSource can get a SelectedValue for the
    // parent GridView
    gvDetail.DataBind();
}

GridView - SqlDataSource 中的客户端 "WHERE" 子句？

GridView - Client Side "WHERE" clause in the SqlDataSource?
