If you want to speed up the site there are other steps you can take. Try reading "Speed Up Your Site" by these guys: http://www.websiteoptimization.com/speed/. This book is really good even though it is a couple years old. It's worth the read.
In .net you can disable viewstates if your are not using them and try to keep your control IDs shorter. The less characters that are sent to the client the faster the site will be.
Although, if your .aspx pages are NOT "doing" anything then static HTML pages would be faster as it won't have to process any code server side.

i am working on web application in which we are using Outproc session mgt.
As we manage session using Outproc there are two ways
1) Sql Server
2) State Server
in above we are using State session mgt.
In this case i want to know if we use Application variable then where actually this variable store on Web Server OR State Server.
Please tell me ... our further development depend on this ....
Thanx in Advance

Well Session object are different than application object so in any case application object will not be there on IIS reset or application stop only the session variables will remain

Hi all I am using following code to bind data with dropdown list
<asp:DropDownList ID="ddPCBackSide" runat="server" Width="150px" DataSourceID="PCBackSideSourceProductFields"
DataTextField="field_defaultvalue" DataValueField="field_defaultvalue">
</asp:DropDownList>
<asp:SqlDataSource ID="PCBackSideSourceProductFields" runat="server" ConnectionString="<%$ ConnectionStrings:sConnectionString %>"
SelectCommand="SELECT field_defaultvalue FROM cp_productfields WHERE field_product_id='Convert.ToInt32(Session["ProductId"])', field_type='DropDownList', field_ID='ddPCBackSide'"
ProviderName="<%$ ConnectionStrings:sConnectionString.ProviderName %>"></asp:SqlDataSource>
I am getting following error during compilation
Error 1 Type 'System.Web.UI.WebControls.SqlDataSource' does not have a public property named 'field_defaultvalue'.
Is there anything wrong in the syntax? Pls let me know.

Try changing the double quotes to single quotes. I haven't looked closely at this but first guess is that is causing the problem.
|
|
|
|
|
SQL query parameters are in single quote.
|
|
|
|
|
'" & Convert.ToInt32(Session["ProductId"]) & "', field_type='" & DropDownList & "', field_ID='" & ddPCBackSide & "'"
try by using this

Can we use static variables to maintain state in ASP.Net Application in place of storing at Application Object? What are merits/demerits
Abhinav

In traditional ASP, we always had the Application object to store application-wide variables in. This of course came at the price of memory allocations. In .NET we can now take advantage of Static Variables, which in most cases can be faster than accessing the Application object.
In .NET, most objects are actually classes, and Global.asax is no exception. To take advantage of this, we first have to give our Global.asax a Classname. We do this by adding the directive naming mine 'MyGlobals':
<%@ Application Classname="MyGlobals" %>
Then, we specify our Static Variable inside the script tags, using the 'Public' and 'Shared' keywords in the Global.asax:
VB:
Public Shared sGreeting as String = "Visit HarrisonLogic.com!"
C#:
Public Static String sGreeting = "Visit HarrisonLogic.com!"
Now that we have the variable 'sGreeting' set up, we can call it directly from our .aspx page using the Class name and the Variable name:
x = MyGlobals.sGreeting
But in case of at some sitiations you may need to acces certain data with respect to the applications like storing number of hit counts for the application.
Major differences
------------------
1) Static variables cannot persist its value after server post backs.
2) But Application object will persist its value after server post backs

i would like to create a .aspx page prgramaticlly in asp.net.

Self modifying code is very rarely needed in programming.
What is it that you think would be best solved using this?

In this case you have to wite Inline script for this page. Simply create a string and save it as ASPX.
Note that in page directive Codebehind attribute should not be there and do write all the login in

Hi everyone,
I have a situation where I must add ImageButtons dynamically on a page. This I managed to do, but I need them to respond to the Click event and they won't.
Here's a snippet which represents what I'm doing:
public partial class _Default : System.Web.UI.Page
{
ArrayList imagenes = new ArrayList();
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
ImageButton ib3 = new ImageButton();
ib3.ID = "ib3";
ib3.ImageUrl = "Puesta de sol.jpg";
ib3.Click += new ImageClickEventHandler(ImageButton_Click);
ib3.Width = new Unit(100, UnitType.Pixel);
ib3.Height = new Unit(100, UnitType.Pixel);
form1.Controls.Add(ib3);
imagenes.Add(ib3);
Session["Imagenes"] = imagenes;
}
else
{
imagenes = (ArrayList)Session["Imagenes"];
foreach (ImageButton ib in imagenes)
form1.Controls.Add(ib);
}
}
protected void ImageButton_Click(object sender, ImageClickEventArgs e)
{
Page.ClientScript.RegisterStartupScript(GetType(), null, "alert('HEY');", true);
}
}
After clicking on the ImageButton, the page reloads, enters the Else clause, the ImageButton is restored, but it won't enter the Click handler.
Also, I tried setting the handler manually inside the Else clause after the control has been added to the form but it won't enter the handler either.
My guess is this is happening because asp.net is actually assigning the handler, but the call to the handler is simply 'lost' during the restoration of the controls since it appears asp.net expects to fire events for 'static' controls only.
I've checked that when a Click event is fired for a 'static' ImageButton, the execution path goes through the Page_Load first and ends into the handler. That's why i re-create the control in the Else clause in Page_Load.
It's not as important for me to get every delegate for each control restored(which i guess it actually is) and working, as it is getting all of them getting into one handler as expected, since I'll possibly assing all of them the same handler.
Thanks a lot in advance for any help you could provide,
Oxi

Ok, strangely enough, when I set the handler now, after re-creating the controls, its working. I'm sorry, i thought i had tested this yesterday already.
I guess I can go on now.
Nonetheless, I'm still interested in a way of storing and retrieving the delegates just in case i stumble uppon a situation where I actually need to use different event handlers for different controls.
Thanks for your support,
Oxi.

Hello All,
I'm trying to develop an application where, i have a flash file running in an ASPX page and that page contains an aspx save button. I need to capture a portion of the screen(i 've filled a rectangle with color and an image in flash-- this need to be captured) and save that as a jpg file in the server on an aspx button click. Code behind is C#.net.
Can anyone help me.
Regards,
jeeva

You can't do that using ASP.NET. As the graphics is shown on the client computer, you will need a component that runs in the browser that captures the graphics and sends it to the server.
You can't even use a server control to trigger the process, as doing so will cause a postback, and when the browser returns from the postback, the page that you wanted to capture is gone.

Thanx for the reply.
can u figure out a possible solution for this?
i somehow want that portion of the screen to be saved on the server.
(Is it possible with javascript or vbscript).

You can't access the graphics of the client using client script. You need something like an ActiveX component or a Java applet.

That is because you haven't set write permission on the database file for the account running the code.
