I have a site that will not use theming. But by default the value is set to true. Does ASP.NET do a check everytime to see if I'm using themes. Is there a performance hit?
View 2 RepliesI have a GridView with a load of data in, there is an ID associated to the data that I would not like to be visible to the users. All worked fine when all the cells were visible, but as soon as I change the ID DataBound column to false, when I try to access the item in code I get "" instead of it's actual value (that worked perfectly when it was visible).

Is this possible without setting 'ValidateRequest' to false?
I have an update panel which has 2 set of controls each in their own separate panels. We can select either panel by a checkbox list and they become visible. Now I am trying to set a value by javascript in the panel that becomes visible on my checkbox click but the problem is that I cant access the controls through javascript as they are not rendered on page as visibility is false.
I cant find the controls inside the page source even though they are visible on page so javascript cannot access them. Is there any way other than doing a postback and setting them visible to access them via javascript?
In my database I have boolean column to declare if something is 'active'. In my web application I would only like one item to be able to have the 'active' status at once.
Therefore I have a radio button list in my aspx page to force the user to select one item. I know it is easy to set the selected item to true through my SQL update statement, but how do I automatically set everything else back to false/null!?
I have the following code which searches through the database and pulls out information. It all works fine:-
PHP Code:
protected void Button1_Click(object sender, EventArgs e)
{
string connStr = "Data Source=SQLB23.webcontrolcenter.com;User ID=wbsd;Password=*******;";
[code]....
Now i also want to show how many fields have been returned so i would want to show the message like so:-
Quote.You searched for ben, which returned 2 results.
How can i alter my code to achieve this?
I have a panel that contains several controls.
On the other hand i have a MultiView that contains Several view that in turn itself contains several controls .
In multiview we have to set ActiveViewIndex for the view which we want to see.
That same thing can be done through Panel containing another seleral panel's and setting its Visible property to True/False accordingly.
Is seems Multiview is just using this Visible property internally to render controls .Since other views (whose Index is not set to be active Index) are processed on the server for its Whole life cycle(I am confused here..whether i am right or not) .Same thing perhaps happen when we use a Panel insteed and use Visible=True/False. So, what is the difference between MultiView and Panel taking this scenario ?
I've GridView with Template field as
<asp:TemplateField HeaderText="Review">
<ItemTemplate>
<asp:ImageButton ID="imgBtnReview" ImageUrl="~/images/agt_reload.png" runat="server" Visible="false" CommandName="Review" CommandArgument='<%#Eval("id")%>' />
</ItemTemplate>
</asp:TemplateField>
Gridview is bound to a table. If a row in table has price greater than zero then the above mentioned Imagebutton should br visible in that row only.
Is it possible to do so.
I have a validator that check an input.
i what that the validator displayed "valid" if the value is valid, and "invalid" if the value is hasnt passed the validation.
can manage without adding an additional label for the valid state(by setting the visibility: true/false)?
does the validator control has am alternative value, or i have to override it?

I have developed a website in asp.net framework 2 . This website is being hosted in two different servers without any change in code. My issue is about the performance of these 2 sites. One website is taking much time for inserting datas to the DB (SQL server 2005). 2 websites are having different DB server.
I think the issue is for the DB server. How can we rectify the DB performance while insertion and Is there any other cause for this permance issue?
I am not sure if this is the right forum. I can not find a forum for LINQ.
I am working on an application using LINQ. Application performance is not up to par and my tests show that it is LINQ queries that are slow. I was wondering if anybody can recommend where I can find an article about optimizing LINQ performance maybe by compilation or other methods.
I am creating a service oriented application where trying to have everything using services....however there is something I am not sure of , I am having a page that calls the database at the page load...so what would be better and faster?? to call database in pageload , or to call wcf service from javascript during javascript load ??btw , I am using a repeater in the page , but I have created somekind of an engine to create the suitable html so...I'll be creating the repeaters html using the wcf and resend it back to the page If I am using a wcf service at the start.
View 1 RepliesI have develop a web application. I have put my web application in my server and user can access from any location.
My server regional and setting is English (US). Now my problem is
1) When user access to my system and his pc setting is English (UK), it will prompt and error
and after i debug i suspect it is because of Datetime conflict (dd/MM/yyyy and MM/dd/yyyy)
2) I cannot fix or limit my user to setting his/her pc regional setting to UK
So what can i do in my web application solve this issue?
(Can i write any code in my client side (.aspx) to convert or do standardization to US)
I would like to set a value:
[code]....
...where [HERE] is the placeholder for my value, from my code behind in ASP.NET before the page is rendered. I generate a guid, and I need that apart of the script on the page.
I have an approve button.on clicking on this button it should show that an inactive value is present .Onclicking yes conformation it should save the data or else clicking on no conformation should return false; how i will do that?After alert it always submit the data.

This is the code i used.how i wiil stay back on Confirm 'no' click?
I'm working with ASP.Net web services and am having a problem with a long-running process that takes about 5 minutes to complete, and it's timing out. To fix this, I was able to set the executionTimeout on the server's web.config to 10 minutes, and then set the .Timeout property on the Web Service object to approximately 9 minutes. Now, I'm worried that this may possibly cause some other web service calls to sit there for 10 minutes before they time out rather than the previous 90-100 seconds. I know the default on the client side is 100 seconds, but wasn't sure if updating the server's timeout setting would affect this.
Bottom line is - Is it safe to update the server's timeout setting to a long amount like 10 minutes, and rely on the default timeout on the client, or could this end up causing some problems?
I am working on an ASP.NET 3.5, C#, ASP.NET AJAX, JQUERY web application which currently is having some performance issues. I have a screen with the forms view control and when I edit the form and save it for the first time the POST takes 4.89 seconds and when I perform the same operation again for the second time the POST only takes 1.09 seconds. What could be the reason for this strange behavior?
Note: I am using firebug and I am disregarding the page resources (like js, images) load time.
EDIT: I am using the Web Deployment Project to precompile the application.
I'm now getting into EF and from what I'm seeing so far, I wouldn't have to worry about writing stored procedures any more. Looks like EF takes care of all of that -- including INSERT's that store data in multiple tables. One of the things they taught us when learning stored procedures was that they're compiled which has performance benefits. How does EF 4 fare against using stored procedures?
View 3 RepliesI'm trying to make a decision about how to display my data. What I have now is a list of products displayed in a repeater. But for code-maintenance I've put my product items in a seperate usercontrol and loading them in a loop with db results using LoadControl.The product control itself is very simple, just a few public properties like title, url, rating but I'm not sure if this will affect my performance. I did some reading here and on forums and some people say it's not the best practice especially if you have more then 20 or 30 of these controls. So, is it really a performance hit using this method or does it stay ok with around 10.000 hits a day.
View 2 RepliesI have developed a gridview which has displays 8,000 records. However, the user is compaining that it is too slow. A major function of this gridview is to filter on two of the columns. It seems to me that if the records were stored in memory it would be much faster. This is caching, I think. Is that the case? Since filtering is being done I don't think custom paging will help much. When they submit a filter, with custom paging wouldn't the entire table be read again? So I was thinking of trying caching which is available on SQL Server. Am I on the right track? Can you cache with an Access database? Can you think of any other ways to improve performance of a gridview?
View 1 RepliesI did not post this in database forum because the data will run on an asp.net site.I have 3 solution in my mind and i would like some opinions.What i want to do is create a parent-child relationship on 2 controls.A listbox and a textbox.I will populate the listbox with data(this is taken care of so ignore) and what i want to do is when i click on an item in the listbox then the textbox to show it's joined related item(one item only).This is not a problem in windows forms app but in asp, since i'm new i don't know what would be better for a faster retrieval on the page.So the 3 options i have in mind are:
1)DAL.The standard create a query and let one @parameter wait for the id.
2)ADO.NET with possibly an sqldatasource.In standard forms i would have chosen simple ado.net but in asp?So either constantly open,close the db and retrieve the item or use an sqldatasource and chance the parameter.
3)Asynchronous handler page.Bind the textbox to an asynchronous page that contains the connection and expect the @id parameter.
I admit that i'm not fond of DAL but if it will boost speed then i will use it.But i have a though that says that simple ADO will be faster.
I have a strange situation on a production server. Connection for asp.net get queued but the CPU is only at 40%. Also the database runs fine at 30% CPU.
Some more history as requested in the comments:
In the peak hours the sites gets around 20,000 visitors an hour.
The site is an asp.net webforms application with a lot of AJAX/POSTs
The site uses a lot of User generated content
We measure the performance of the site with a testpage which does hit the database and the webservices used by the site. This page get served within a second on normal load. Whe define the application as slow when the request takes more than 4 seconds.
From the measurements we can see that the connectiontime is fast, but the processing time is large.
We can't pinpoint the slowresponse the a single request, the site runs fine during normal hours but gets slow during peak hours
We had a problem that the site was CPU bound (aka running at 100%), we fixed that
We also had problems with exceptions maken the appdomain restart, we fixed that do
During peak hours I take a look at the asp.net performance counters. We can see behaviour that we have 600 current connections with 500 queued connections.
At peak times the CPU is around 40% (which makes me the think that it is not CPU bound)
Physical memory is around 60% used
At peak times the DatabaseServer CPU is around 30% (which makes me think it is not Database bound)
My conclusion is that something else is stopping the server from handling the requests faster. Possible suspects:
Deadlocks (!syncblk only gives one lock)
Disk I/O (checked via sysinternals procesexplorer: 3.5 mB/s)
Garbage collection (10~15% during peaks)
Network I/O (connect time still low)
To find out what the proces is doing I created to minidumps.
I managed to create two MemoryDumps 20 seconds apart. This is the output of the first:
!threadpool
CPU utilization 6%
Worker Thread: Total: 95 Running: 72 Idle: 23 MaxLimit: 200 MinLimit: 100
Work Request in Queue: 1
Number of Timers: 64
and the output of the second:
!threadpool
CPU utilization 9%
Worker Thread: Total: 111 Running: 111 Idle: 0 MaxLimit: 200 MinLimit: 100
Work Request in Queue: 1589
