等待操作超时-延长超时时间

Question

I have a grid view that is populated on a button click event:

    <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();
}

The query can take up to 45 seconds in SSMS and is resulting in the website crashing:

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

Until a more efficient query can be created, is it possible to make the timeout period longer so that the program wont crash?

Answer 1

You could increase the CommandTimeout property. Add the OnSelecting event handler of your SqlDataSource , and in your code behind add the following:

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