We have a .aspx file which has about 400 lines of javascript code. Is it a good idea to have such huge code in its own file? What is the performance difference in having huge javascript code in aspx as against the .js file?
View 5 RepliesI was thinking about the performance when I use code to hide some control in aspx page using delimiters or in cs file. For e.g. If I have a panel and I want it to get shown following some condition, so I can achieve this by two ways
1: Using code in aspx file, something like this
<% if(isAllowed) { %>
<asp:Panel ...></asp:Panel>
<% } %>
2: In the code file, something like this
<asp:Panel ID="pnlMyPanel" Visible="false"></asp:Panel>
And in cs file
if(isAllowed)
pnlMyPanel.Visible=true;
In my view, first way should be good as it will not at all create any Panel in the page. Am I correct here?
Does it have any major effect on performance/ memory if my web.config is really huge (say, 1000+ entries in <appSettings>)? Is it a good idea to maintain a different custom xml config file for all business specific settings for my app?
View 3 RepliesI have one Store Procedure that generating report ..
For storing the data there , i used many temp. tables. There is many Select Query , little less insert and delete query.
Now if there is huge data around 1 lac in temp table my select query taking to much time and also may be insert and delete query
I added Primary key to all auto Increment Field in temp table. Also defined Clustered index on that primary key as unique Clustered index to improve the performance .
But there is not so much improvement in case of huge temp table.
Right now the whole Store Procedure is taking time to complete around 1.5 days or around 30 hours ..
So i want to increase the performance as much that it completes on nearly 3-4 hours.
I was wondering which of these two is better from the aspect of performance.
I was thinking that possibly Class files stored in App_Code works faster because they are sort of pre-compiled but i am not 100% sure.
Specifically i am overriding onInit event on each page using some functions that i am not certain where to place.
Not that i complaint on the speed but i want to be sure that i am doing the right thing.
I am working on an ASP.NET project that has significant backend processing existing in PLSQL. I was wondering if I re-write this code properly in C# can I get similar performance results or is the PL/SQL code going to beat my C# code every time?

I can extract that files in a folder and then copy them to all 100 websites folders
I can extract the archive directly to 100 websites folders
which one is better in performance and less prone to errors

View 2 RepliesI'm currently exporting a database table with huge data (100000+ records) into an xml file using XmlTextWriter class and I'm writing directly to a file on the physical drive.
_XmlTextWriterObject = new XmlTextWriter(_xmlFilePath, null);
While my code runs ok, my question is that is it the best approach? Or should I write the whole xml in memory stream first and then write the xml document in physical file from memory stream? And what are the effects on memory/ performance in both cases?
EDIT
I will indeed be using XmlTextWriter but I meant to say whether to pass a physical file path string to the XmlTextWriter constructor (or, as John suggested, to the XmlTextWriter.Create() method) or use stream based api. My current code looks like the following:

View 2 RepliesI'm working on a C# web app and I've to handle some javascript code.
I can do it both using javascript injection from my .cs file, which I'm doing now or choose to include my code into an external js file.
I would like to know when you would prefer to choose one way over the other.
According to me, it can be more clear to put code in external .js file and it can ease debugging.
Code injection from code-behind would however keep together all the necessary code for my component.

$.ajax({ [code]....

View 3 RepliesI have a relatively simple page that will do most of its operations on the client side using Javascript or JQuery. However, initially I do need to retrieve some data from the DB server based on QueryString parameters.
I plan on passing this data in the form of a JSON string to the script by an old-fashioned ASP manner ( var severData = <%=MyPublicData %>) block where MyPublicData is defined in CodeBehind as:
Public string MyPublicData;
The question is, which event in the ASP.NET page lifecycle is the best for this? Page_Init ? Page_Load? Also, is it worth the effort to do this in ASP.NET MVC. I did look at this possiblity but it seemed a little too much for a simple page like this where I do more 90% of the work on the client.
