Question

我无法弄清楚如何在UpdatePanel中使用SqlDataSource.Update（）来避免页面刷新。这是应用程序结构：

Div点击事件调用ASP:Button＆gt; ASP:Button OnClick事件调用后面的SqlDataSource.Update（）代码＆gt;数据库列已更新

我试图在不刷新页面的情况下完成所有这些操作。这是我的代码：

Default.aspx的：

<form id="form1" runat="server">

    <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true" EnablePartialRendering="true"/>

    <asp:Timer ID="Timer1" runat="server" Interval="10000" OnTick="Timer1_Tick" Enabled="True" />

    <div class="square" id="myId" runat="server">
        <div class="content">
            <div class="table">
                <div class="table-cell">
                    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true">
                        <Triggers>
                            <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
                            <asp:AsyncPostBackTrigger ControlID="myBtn" EventName="Click" />
                        </Triggers>
                        <ContentTemplate>
                            <asp:Button ID="myBtn" runat="server" Text="Button" OnClick="my_Click" />
                            <p id="MyText" class="p">Unavailable for Dispatch</p>
                            <asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" DataSourceID="SqlDataSource1" CssClass="Grid" RowStyle-HorizontalAlign="Center" DataKeyNames="PhysicalAddress">
                                <Fields>
                                    <asp:BoundField DataField="OwnerName" HeaderText="OwnerName" ShowHeader="False" SortExpression="OwnerName">
                                        <ControlStyle BorderStyle="None" />
                                        <ItemStyle BorderStyle="None" />
                                    </asp:BoundField>
                                    <asp:BoundField DataField="Building" HeaderText="Building" ShowHeader="False" SortExpression="Building" ItemStyle-CssClass="building">
                                        <ControlStyle BorderStyle="None" />
                                        <ItemStyle BorderStyle="None" />
                                    </asp:BoundField>
                                    <asp:BoundField DataField="TimeOn" HeaderText="TimeOn" ShowHeader="False" SortExpression="TimeOn">
                                        <ControlStyle BorderStyle="None" />
                                        <ItemStyle BorderStyle="None" />
                                    </asp:BoundField>
                                    <asp:BoundField DataField="IPAddress" HeaderText="IPAddress" ShowHeader="False" SortExpression="IPAddress" ItemStyle-CssClass="hide">
                                        <ControlStyle BorderStyle="None" />
                                        <ItemStyle BorderStyle="None" />
                                    </asp:BoundField>
                                    <asp:BoundField DataField="PhysicalAddress" HeaderText="PhysicalAddress" ShowHeader="False" ReadOnly="True" SortExpression="PhysicalAddress" ItemStyle-CssClass="hide">
                                        <ItemStyle CssClass="hide" />
                                    </asp:BoundField>
                                    <asp:BoundField DataField="Available" HeaderText="Available" ShowHeader="False" SortExpression="Available" ItemStyle-CssClass="hide">
                                        <ItemStyle CssClass="hide" />
                                    </asp:BoundField>
                                </Fields>
                                <RowStyle HorizontalAlign="Center" />
                            </asp:DetailsView>
                        </ContentTemplate>
                    </asp:UpdatePanel>
                </div>
            </div>
        </div>
    </div> 
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:MyDbConnectionString %>" SelectCommand="SELECT [OwnerName], [Building], [TimeOn], [IPAddress], [PhysicalAddress], [Available] FROM [MyDb] WHERE ([OwnerName] = @OwnerName)" UpdateCommand="UPDATE [MyDb] SET [Available] = CASE WHEN Available = '0' THEN '1' ELSE '0' END WHERE ([OwnerName] = @OwnerName)"> <SelectParameters> <asp:Parameter DefaultValue="My Name" Name="OwnerName" Type="String" /> </SelectParameters> <UpdateParameters> <asp:Parameter Name="OwnerName" /> </UpdateParameters> </asp:SqlDataSource>

jQuery Div点击事件：

$('#myId').on('click', (function (clickEvent) {

    document.getElementById("myBtn").click();

    })
)

Default.aspx.cs

    protected void my_Click(object sender, EventArgs e)
{
    SqlDataSource1.UpdateParameters["OwnerName"].DefaultValue = "My Name";
    SqlDataSource1.Update();
    Response.Redirect(Request.Url.AbsoluteUri);
}

请记住，所有这些都可行，但在ADO.NET事件之后不能刷新整个页面。这是事件输出：

感谢您的任何建议。

Answer 1

我查看了上面发布的事件输出并回答了我自己的问题。

我将代码隐藏更改为：

    protected void my_Click(object sender, EventArgs e) {
SqlDataSource1.UpdateParameters["OwnerName"].DefaultValue = "My Name";
SqlDataSource1.Update();}

...当然我不再称为Response.Redirect。它现在按预期工作。

谢谢！

使用AJAX的ASP.net SqlDataSource.Update按钮
