等待操作超时-延长超时时间

Question

我有一个在按钮单击事件中填充的网格视图：

    <asp:GridView CssClass="hoursGrid" ID="hoursReportGridView" runat="server" AutoGenerateColumns="False" BackColor="#DEBA84" BorderColor="#DEBA84"
        BorderStyle="None" BorderWidth="1px" CellPadding="3" CellSpacing="2" DataSourceID="SqlDataSource2" OnRowDataBound="hoursReportGridView_OnRowDataBound" DataKeyNames="DifferentUsers, DoubleBookedFlag, PointPerson, Person">
        <Columns>
            <asp:BoundField DataField="Person" HeaderText="Person" SortExpression="Project" />
            <asp:BoundField DataField="Project" HeaderText="Project" SortExpression="Project" />
            <asp:BoundField DataField="ProjectType" HeaderText="Project Type" ReadOnly="True" SortExpression="Sprint" ItemStyle-HorizontalAlign="Center" />
            <asp:BoundField DataField="Theme" HeaderText="Theme" ReadOnly="True" SortExpression="Theme" ItemStyle-HorizontalAlign="Center" />
            <asp:BoundField DataField="StoryNumber" HeaderText="Story Number" SortExpression="Story" ItemStyle-Width="6%" ItemStyle-HorizontalAlign="Center" />
            <asp:BoundField DataField="StoryTitle" HeaderText="Story Title" SortExpression="Story" ItemStyle-Width="20%" />
            <asp:BoundField DataField="Effort" HeaderText="Effort" SortExpression="Effort" ItemStyle-HorizontalAlign="Right" />
            <asp:BoundField DataField="Task" HeaderText="Task" SortExpression="Task"  ItemStyle-Width="20%" HtmlEncode="false" />
            <asp:BoundField DataField="OriginalEstimateHours" HeaderText="Original Estimate" SortExpression="OriginalEstimateHours" ItemStyle-HorizontalAlign="Right" />
            <asp:BoundField DataField="Monday" HeaderText="Mon" ReadOnly="True" SortExpression="Monday" ItemStyle-HorizontalAlign="Right" />
            <asp:BoundField DataField="Tuesday" HeaderText="Tues" ReadOnly="True" SortExpression="Tuesday" ItemStyle-HorizontalAlign="Right" />
            <asp:BoundField DataField="Wednesday" HeaderText="Wed" ReadOnly="True" SortExpression="Wednesday" ItemStyle-HorizontalAlign="Right" />
            <asp:BoundField DataField="Thursday" HeaderText="Thurs" ReadOnly="True" SortExpression="Thursday" ItemStyle-HorizontalAlign="Right" />
            <asp:BoundField DataField="Friday" HeaderText="Fri" ReadOnly="True" SortExpression="Friday" ItemStyle-HorizontalAlign="Right" />
            <asp:BoundField DataField="Saturday" HeaderText="Sat" ReadOnly="True" SortExpression="Saturday" ItemStyle-HorizontalAlign="Right" />
            <asp:BoundField DataField="Sunday" HeaderText="Sun" ReadOnly="True" SortExpression="Sunday" ItemStyle-HorizontalAlign="Right" />
            <asp:TemplateField HeaderText="Total" ItemStyle-HorizontalAlign="Right">
            <ItemTemplate>
                 <asp:LinkButton ID="taskLinkButton" Text='<%# Eval("Total") %>' Enabled='<%# Eval("StoryTitle").ToString() != "" %>' runat="server" OnClick="taskLinkButton_Click" />
            </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

C＃：

private void generateReport()
{
    //set sql parameters
    SqlDataSource2.SelectParameters["userParam"].DefaultValue = currentEntity;
    SqlDataSource2.SelectParameters["startDateParam"].DefaultValue = startingDay.ToString();
    SqlDataSource2.SelectParameters["endDateParam"].DefaultValue = endingDay.ToString();
    SqlDataSource2.SelectParameters["orgTeamPK"].DefaultValue = orgTeam;
    SqlDataSource2.SelectParameters["productId"].DefaultValue = productId;
    SqlDataSource2.SelectParameters["theme"].DefaultValue = themeSelected;
    hoursReportGridView.DataBind();
}

在SSMS中，查询最多可能需要45秒，导致网站崩溃：

等待操作超时

说明：执行当前Web请求期间发生未处理的异常。 请查看堆栈跟踪，以获取有关错误及其在代码中起源的更多信息。

在创建更有效的查询之前，是否可以延长超时时间，以使程序不会崩溃？

您可以增加CommandTimeout属性。 添加SqlDataSource的OnSelecting事件处理程序，并在后面的代码中添加以下内容：

protected void SqlDataSource2_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
    e.Command.CommandTimeout = 60;
}
