等待操作超时 - Lengthen Timeout Period

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();
}

SSMS 中的查询最多可能需要 45 秒，并导致网站崩溃：

The wait operation timed out

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ComponentModel.Win32Exception: The wait operation timed out

在可以创建更高效的查询之前，是否可以延长超时时间以使程序不会崩溃？

Answer 1

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;
}
