Web Forms :: Asp Web User Controls Performance
Nov 18, 2010
i have a web application with master and content pages i just wanna know that can i use web user controls(.ascx) instead of these content pages and load them dynamically according to user clicks on the menu does using user control affects performance. i wanna load data from sql server in controls placed in web user controls so i m confused that it ll be a performance hit as i have to load the user control after every postback..plz give me suggestions on this. is there any performance testing tool that i can use to see the load on server.

I created an ASP page which contains a MultiView and two buttons, it is as below
<div style="width:700px; background-color:White">
<asp:MultiView ID="mvAgreement" runat="server"
onactiveviewchanged="mvAgreement_ActiveViewChanged"> [code]...
The first and third view are simple now.The second view contains a user control AgreementDetailUC, which dynamically loads many other user controls onto several dynamically created tabs, as show below
AgreementDetailUC.ascx is like:
<div style="width:700px; background-color:White; text-align:left">
<cc1:TabContainer ID="tcAgreementDetail" runat="server" Height="300px" AutoPostBack="false">
</cc1:TabContainer>[code]....
When <Next> and <Previous> button is clicked, it take several seconds to show the second view. Page_Init is run very fast, it seems the time is spent on rendering the page.
My questions are:
1. How can the performance be improved?
2. How to change the cursor to hour glass when a button is clicked and change it back when the new view is shown (I can set it to hour glass when a button is clicked, but don't know how to set it back to normal).

I tried to find out about subject but with no success. The point is that in the beginning I've made many user controls. My site is too slow. I have not idea yet if it is because of user controls.

I have been playing around with loading user controls in a CMS style where I can change the position and order. I have come up with this...
[Code]....
It all works fairly well - but I have alot of propertys in my user control code behinds where I could inject values into the usercontrol from my base class.
I like the way I can position usercontrols from the DB, I even added a time and date section where they could be switched on and off per day or time.
If I make every user control access the DAL for the data, it means i will have one select per user control, which means including my bassclass I could have upto 15 selects (visits tot he DB) to make the front page. Though this does not seem to make a performance problem, I was wondering if there was a better way of doing this.

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 have developed a gridview which has 7,000 records with some filtering. However, theuser is compaining that it is too slow. 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? Can you updaterecords this way? Can you cache with an Access database or do you have to use SQL Server? Can you think of any other ways to improve

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 trying to speed up a Gridview on my page that reads 8,000 records using an AccessDataSource. So I am trying to implement caching. I have used the information given here: [URL] but it has made no difference in the response time. Can anyone direct me on this? Is there something you have to specify in the gridview (besides the datasource). Would it work if I went to SQL Server?
This is my AccessDataSource code. You can see the 3 relevant lines starting 6 lines from the top.

I just wondering if the DataPager is equal to the MySQL limit command, if I use the limit I get the number of rows I asked for. Is it the same with the DataPager? Or does it get the full query table and only then filter?

I have developed a application using Visual Studio 2008 and SQLServer 2008. I have a page called "Billing Center" where i need to display more than 500 records in a gridview and the gridview has sorting enabled. If i limit the page size upto 10 only the gridview performs well but user requirement is to view atleast 500 records at once which is slowing down the gridview record retrieval process.
I am using the following C# code in code behind to sorting, paging and retrieval . Please guide me what am i doing wrong in this code and how to make it work with large data set.

I have an SP in backend that retreives multiple recordset/DataTable where each recordset/Datatable contains 10 records and 8 columns.
The Count of recordset/Datatable differs based on parameters.
The SP retreives Data in nearly 0.01 seconds.
I have been displaying the records by looping each Datatable and each record in DataGrid Template Control, this way the page loads very slowly.
Can some one please suggest me on how to display/Load the data more efficiently and faster in front end ASP.NET 2.0?
Can I perform some Multithreading to display records from different datatables?

I have created the stored procedure in SQL server 2005. i have used nested cusrsors in this SP. also many records are there. So, its performance is too low.
i forced to use cursor, because the this is calcualtion process. i have to fetch the records one by one, do the calculation and insert the result to the another relevent tables.
So it cause big performance issue.this is my sample scanario.
First i have to take the products from the customerforecast for the certain duration. (i used cursor to fetch the products)
then i need to get the list of machines can run for the each product. (i used cursor to fetch the machines)
then i have to fetch the Unit per hour value for the combination of machine and prduct.then i have to use formula and do the calculation and store the result to the 3 different tables.
