Timeout when calling SqlDataAdapter.Fill(DataSet)

Posted By:      Posted Date: September 13, 2010    Points: 0   Category :ASP.Net
This issue has stumped me for a while.  Hopefully someone here can give me some insight. When my site runs the following code it works just fine 99% of the time. Dim sda As New Data.SqlClient.SqlDataAdapter(cmd) Dim ds As New Data.DataSet Try sda.Fill(ds) Catch ex As Exception ... The command is calling a SQL Server 2005 stored procedure that takes 20 parameters and returns 6 tables of about 5-50 rows each. The paramters are all NVARCHAR, INT, or BIT data types.  Only one of the parameters is Input/Output. There is a total of about 100 rows returned. Normally this takes a fraction of a second, but for some queries, it times out after 30 seconds. When I run the exact same query in the Management Studio query window it takes 1 second. Any idea what I can do to get the same performance from .Net as I am getting from Management Studio?

Webservice timeout while calling windows service



We have a .net product built in .Net 2.0.
It consist of three blocks.
First is a asp.net web application which calls webservice which in turn call a windows service to get results from database.
Our problem is that windows service is taking time to get results from database because of which timeout is occuring.

Now we have already set timeout property in web application while calling web service through proxy. However, we could not find how to set timeout property for webservice(This will stop webervice from timeout before windows service send back the result).

If somebody have done it, please help


Intermittent timeout calling ASMX web service yet Upload data transfer completes OK

I'm calling my webservice from a web page and getting a timeout despite setting very high values in my web.config files. This occurs intermittently when the file is usually pretty large but yet the file is still getting uploaded completely (as if the timeout DID NOT occur). Here is a function in my .aspx file which calls my ASMX proxy class:
private void UploadFile(HttpPostedFile postedFile, string fileNameOnly) 
    // create an instance of the proxy class to talk to our service; calling it client: 

ReportViewer Control large dataset timeout


Reporting Services 2008 R2

I have a rather large report that returns around 40,000 records. (I've tried telling the business that this is not a useable report and no one is listening.)

When I execute the report through a webservice and stream it to an excel file the response time is fine.  Trying to load the report using the report viewer control it just hangs.

When I run the report through SSRS own Report Manager, I get the following error

  • An error occurred within the report server database. This may be due to a connection failure, timeout or low disk condition within the database. (rsReportServerDatabaseError)
    • Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.



This is on my own local dev machine at the minute and I've only just gotten the correct dataset it will be run against.

The stored proc runs in a couple of seconds.

Does anybody have any suggestions in what I can do?

Any help would be appreciated.

TableAdapter/DataSet calling Stored Procedure



I am able to get data with an TableAdapter using OracleClient (ODP.NET) and typing SQL statements.

Now I want to just call a stored procedure from the database instead of calling a command like "select * from table".  But I cant choose "Use existing stored procedures", just "Use SQL statements" in the TableAdapter Configuration Wizard. So how to call a procedure?

Introducing ADO.NET and the Typed DataSet

In reviewing the applications it seemed everything they were doing involved database reads, writes, and manipulation. The development staff had been reviewing the articles and code samples for ADO.NET. They had spent many years refining their existing ADO based infrastructure and perfecting their use of ADO

Create and Use a Typed DataSet by Using Visual C# .NET

This article shows you how to create and use a typed DataSet in a small Web application. Typed DataSets, which inherit from the DataSet class, create first-class members of a DataSet's DataTables and DataColumns, yielding the many benefits that come with the use of strong typing.

Persist large dataset across ASP.NET pages. No database


Can anyone give me suggestions on how to implement the following requirement?

1. A online wizard (step-by step operation) processes user requests across several ASP.NET pages.  The session data is stored in memory until the user submits the request.  Once the request is submitted, a XML file is created and the data are passed to XML.

# Case Study: The parent page has a "select" button.  Click "select" will pop up a child page.  The users can select 1000+ items from a datagrid in the child page.  Once the user clicks "confirm", the selected items in the child page will be populated to the selected item gridveiw in the parent page.  The user can keep selecting more in the child page and the selected items will be appended to the gridview in the parent page.


- What's the best way to extract strings from a text file and convert to a dataset in memory and then present it in a datagrid in UI?

- What's the best way to persist and manipulate a large dataset across pages?  Session? or ViewState? Can it be accomplished by LINQ?

The app doesn't interact with a DB.  Once the request is submitted, it will convert the in memory data to a XML file.  What technology can be used to accomplished this?&nb

Why not Dataset use to Saving?


Hie Friends,

I have searched on net and even i worked on 2 huge shipping projects.

Everywhere i found that while binding data to control use dataset but when we save, they recommend use command (use generic collection and create command object with store procedure) why not we use dataset as in .NET 2.0 it is improved lot and data adapter has new feature batchupdatesize.

why we need to create property page which maps to all column in a database.

E.g. if i have employee table with empid and empname in database then i use to create emp.cs with properties of empid and empname and use same properties for saving. If i use these properties for validation in business rule then no problem. But why we use them in saving for creating command object.


SQL 2008 timeout


I am recently getting a timeout exception when executing this method. This table stores images and it might be due to the size of the table. I have no idea! Help!

DAL Dataset showing all the column


I follow the tutorial and create DAL with Dataset. I created a Table Adapter with many column, but when i Call a simple Get for 2 column only. The system display 2 column and the rest column with empty data.

My question is that will this affect the performance? because i only need 2 column.

example: Table with 40 column define in Dataset in DAL. I have GetMember from Dataset with 40 column, some request only 1 column (with 39 empty), some request 22 column (with 18 empty column). Will this affact the performance?

Should i create a seperate DatasetAllColumn, Dataset1Column, Dataset22Column ?? so system only return exact column i need. and hofully the performance is optimized to it best.

ReadXML Timeout


I am reading an XML file from an external URL and putting it into a dataset that is the populates a repeater. This works fine when I run it locally, however on the published web site I receive A connection attempt failed because the connected party did not properly respond after a period of time error messages.

However, if i type the URL directly into a browser, I get the XML file almost immeadately which leads me to believe that I am going about this the wrong way or I need to some how to extend the timeout period.

Here is my code:

Protected Sub ButtonValidate_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ButtonValidate.Click
        If Page.IsValid = False Then
        End If

        TableCellVATSIMIDResults.Text = "<br />VATSIM ID Validation Results for <i>" & TextBoxVATSIMID.Text & "</i>"
        Dim DataSetVATSIMValidation As New DataSet
        DataSetVATSIMValidation.ReadXml("http://cert.vatsim.net/cert/vatsimnet/idstatus.php?cid=" & TextBoxVATSIMID.Text)


<asp:Repeater runat="server" ID="RepeaterVATSIMValidation">

Calling webservice from the server


I have a sample web service and aspx file. I deployed them to an existing website that contains classic asp files.

web-service: --- using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Services; [WebService(Namespace = "http://localhost/MyWebServices/")] public class MembershipRegisWebService : System.Web.Services.WebService { public MembershipRegisWebService () { //Uncomment the following line if using designed components //InitializeComponent(); } [WebMethod] public string HelloWorld() { return "Hello World."; } }

aspx.cs file: --- using System; using System.Collections.Generic; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.Services; public partial class CallWebService : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { MembershipRegisWebService mrWs = new MembershipRegisWebService(); Response.Write("Calling web service:" + mrWs.HelloWorld()); } }

It runs locally, but it shows an error when running it from the server:
