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.
View 7 RepliesI have a simple user control which is nothing but a simple input field with runat="server":
<input id="mySimpleTextBox" type="text" runat="server"/>
My observation so far in the output rendered by a datalist (when I use this user control inside it) is that the value for the name attribute is the same.I want to use this control inside a datalist/repeater such that I'd want a unique value for the input element's name attribute when the datalist/repeater renders. How is this done?
EDIT: My bad obversation. Actually the names are unique. However, when I try to post the page to another web page which outputs the key & value of all the items in Request.Form I don't see the input elements...
I would like to know the performance impact of using the culture invariant resources instead of culture specific ones.
For example, we plan to deploy a website and not have any en-US resources. This is because our culture invariant resources are always identical to the en-US resources.
When adding a new page or user control to an ASP.NET webforms application, the code-behind class contains an empty Page_Load() event handler:
public partial class Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
}
I have an existing web app, where many pages and controls still contain these empty event handlers (they are not used).
Question: Is there any performance impact due to these empty event handlers and should they therefore be removed from all pages and controls?
Does putting multiple classes in one file impact performance? Has anyone had any experience with this.
I've read various discussions around application structure and logic of where code can be found with regard to design best practice but little has been said as whether there is any negative/positive/neutral impact on performance.
In my website I am using thread to perform the function which downloads the CSV from a website and parses the data into the database.
Now if I am not able to stop the thread then what could be the impact on the performance?
Also If I unknowingly start another thread then would it impact my website's performance?

I have an ASP.net VB Web app I'm working on that has a requirement to provide a list of all our component part numbers to our engineers for selection into a custom Bill of Materials for reworking of an assembly. The list of part numbers is currently generated from a stored proc in our MRP systems/SQL database. The number of records being generated is slightly over 39K part numbers.
Although the SP only takes a few seconds to generate the data the web page is taking a couple of minutes to load, primarily because of the time to fill the control presenting the records to the engineers. I've bound the data to a combobox control to the engineer. They want to be able to type the first few characters of the part number if they know it and have the list filtered or be able to just scroll the data to find the part they are looking for.
I've read elsewhere that they may be a way to only populate a certain quantity of records rather than all 39K then filter based on the users actions. Unfortunately the discussions about doing this didn't provide any examples, references, etc.
My questions are these...
Is there a better way to handle this quantity of records than a stored proc and combobox? A
ny examples of a method to populate a certain number of records then filter based on user action?
I have developed one simple application in that i am using mysql database. but my database size more thatn 4,50,0000, as well as ecah and every second my database is updated i.e record ll be added to the table how can i get the details for one single click.
View 1 RepliesI'm building a asp.net web application with lots and lots of controls and huge volumes of data. My application is very slow and it is taking a large amount of time to load the data into the .net controls like grid, tree view etc. I also have some ajaxified pages and controls in my application. I want to reduce the page load time in each postbacks.What are the standards/best practices to be followed while developing large asp.net applications?
View 3 RepliesI want to insert a large amount( approx 7000 records) of data into a table, My scenarios is that i need to check whether the record already exists then it will not insert it. Currently i am using a stored procedure for this which gets called for each record.
IF EXISTS(SELECT 'True' FROM MYTABLE WHERE ID = @ID)
BEGIN
--This means it exists, return it to ASP and tell us
SELECT 'This record already exists!'
END
ELSE
BEGIN
--This means the record isn't in there already, let's go ahead and add it
SELECT 'Record Added'
IF EXISTS(SELECT 'True' FROM [Aadil].[dbo].[SharePointSitesData] WHERE ID <> @ID)
I have 65 columns in the grid, if the columns are reduced to 20 then the speed when accessing from client is more or less similar to that accessing from web browser. Does it mean that all this performance issue is due to the data only ???
View 1 RepliesIn my database m having 1000 record and I want to display 10 record on each page on gridview so every time it fetch 1000 record so while page loading it is quite time consuming ..
View 1 RepliesI have about 5,00,000 data. I want to display the records according to group by. It takes to me about 2 minutes. Is it good?
If not, then what is best process to display the record in a very fast way?
Moreover, I have encrypted one field in database and encryption is done from my code behind. So when I display the records, I have to decrypt those. That's why I make paging on 100 records per page.
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.
View 9 RepliesI have a web performance test which contains a request whose response is greater than 5MB, and the Extract Hidden Fields rule fails to find (necessary and required!) hidden fields in the response. Response header contains
HTTP/1.1 200 OK
Transfer-Encoding : chunked
Vary : Accept-Encoding, User-Agent
Cache-Control : private
Content-Type : text/plain; charset=utf-8
Date : Sat, 19 Feb 2011 15:24:38 GMT
Server : Microsoft-IIS/6.0
X-AspNet-Version : 2.0.50727
X-Powered-By : ASP.NET
Other than that and the response size, there is nothing remarkable about this scenario. In fact, this same test succeeds when a smaller data set is used. I suspect the Web Performance Test framework is having issues parsing the "chunked" encoding or sheer volume of data. Ahem, how can I obtain these required hidden fields from my response? ie resolutions, work arounds, converting auto-extraction to manual, etc.

View 1 RepliesI 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 have a user control that is common to the application. It searchs for lakhs of Items in one go from the db and I set the selected Items in a list in a session to pass on to the pages that use it. Hence making the application a tad slower. The gridview that contains the Items should have sorting, page indexing. What according to u,I should do to enhance the application's performance ?
