Hi Munklefish 
Well, now that I've looked your code over again, it seems that you fill the DataTable with very different data for each request, based on the search being done. The method I was referring to is most useful if you have a couple of tables that very seldomly change, then you can load those into Applicationstate (a piece of RAM on the webserver that is shared between all users).
It would work something along the lines of (coding from memory here - might need a bit of IntelliSense later  ):
protected void LoadData()
{
if(Application["myData"] == null)
{
dsMyData = new DataSet();
SqlDataAdapter adapter = new SqlDataAdapter("SELECT * FROM orders", strConnectionString);
adapter.Fill(sdMyData, "orders");
Application["myData"] = dsMyData;
}
else
dsMyData = (DataSet)Application["myData"];
}
This requires your connectionstring to be in the variable strConnectionString and a DataSet named csMyData to be declared on the Page level. Then you can call the LoadData method from the PageLoad eventhandler, and you will always have the tables in RAM, except for the first time of course. Application is emptied when the last users Session times out (by default 20 minutes after his/her last click on the page).
Since you actually don't need the DataTables in the code you showed me, then the DataReader is actually faster for just getting stuff from the DataBase. (also from memory ... don't hit me if it's not perfect!)
SqlConnection connection = new SqlConnection("server=(local);database=shop;user=me;password=secret");
SqlCommand command = connection.CreateCommand();
command.CommandText = "SELECT * FROM orders WHERE ...yadayadayada...";
connection.Open();
dlOrders.DataSource = command.ExecuteReader();
dlOrders.DataBind();
connection.Close();
Hope this was of some use to you.
Kind regards - Jakob

After I covert a 2005 Web Site Project to a 2005 Web Application Project, I got the following Error on a web reference which point to a web service. I removed the reference and add it again but got the same error:
Custom tool error: Unable to import WebService/Schema. Exception of type 'System.Exception' was thrown.
Any help is appreciated.

Thanks, that's what I did. Actually you need to compile a program to generate the machinekey. Just thought that could be added into the Service State to be better solution!
I am writing my own Session State, will see how it comes out
Thanks for all your help!

Hello,
I am trying to figure out how to get a textbox in a template field to autopostback. I added a text box to the item template and set the autopostback to true, and it does actually post back. However, I am trying to read information from that text box that caused the post back and I always get a null reference error. How do I make the text box content available in the TextChanged event within the Gridview? Thanks in advance.

I have the global.asax file, generated by Visual Studio 2005, with the usual Application_Error method, that's supposed to handle all uncatched exceptions in the web application.
Well, this method is never called, even when I force a NullReferenceException intentionally.
I'm using ASP.NET 2.0.
Does anyone can help me?

Hi Dario. What does your Application_Error code look like? Is it possible it is getting called, but not coded in such a way as to make that obvious?
Another possibility is if the exception is generated on a different thread than the main ASP.NET thread. Here's an article that describes it better than I can (Look about halfway down for ASP.NET specifics):

It simply writes in a log (SQL Server) a message including the exception.

I think that is the problem, because after a few tests I noticed that Application_Error has been called some times, but not all the times it should have been called.
Thanks!

Looking for a little help. I have a web app that is timing out between 10 and fifteen minutes. The problem is that I have my Session State Timout set to 20 (in Web.Config) and my IIS AspSessionTimeout is set to 20 minutes.
Anyone have any ideas?
Thanks for your time and consideration,
-B

Hi there.
I made an app that displays string, lines and stuff (the code is in Page_Load). I need a way to make sure that part of what is on the asp.net page gets printed on one page and part on another page. I thought that could be achieved by locating what I need way down with a high y value (above 1300) but it didn´t work. Then I tried saving the image on the hard drive and then print out but it didn´t work either, all still get´s printed out on one page (the first).
How can I control what goes on the first page and what on the second page when the contents of my page get printed out on a printer of a user that visits my page?

One strategy would be to use the CSS style attribute page-break-before: always;. Here's an example of what I mean:
<html>
<head>
<title> Page Breaks with CSS </title>
</head>
<body>
<form runat="server">
<p>This text should print on the first page</p>
<p style="page-break-before: always;">
This Text should print on the second page
</p>
</form>
</body>
</html>

Is "ClassName" defined in a .vb file local to the project? Is "ClassName" part of a compiled assembly? If the latter, make sure you have added a reference to the compiled assembly in the new project.
|
|
|
|
|
The class is a ClassName.vb file. Originally is located on app_code folder. After I covert to web application project, it located on old_app_code folder.
|
|
|
|
|
Just guessing here - but should you move it to app_code in the new project then?
|
|
|
|
|
Just find it out I need to put the project name before the class name:
Dim cls As New ProjectName.ClassName
Thanks for the help.
