In a page load routine I put items in a listbox. I only want to do this one time. I have the following code which works but I'm thinking there's a better way to do this.
if HiddenField.Value = 0 then
HiddenField.Value = 1
other stuff
end if
I am working on a ASP.NET 2.0 application. It is hosted on IIS 6 on Windows 2003 server.
Few pages have jpeg images (around 50 images and 50 KB each). It takes long time to load the page for the first time. But when i open the same page for the second or third time it is faster.
why does a web page take long time to load for the first time?
Is it cached somewhere when it loads for the first time? Do we have any control over it?

Issue:
As my pages are taking time to load first time.
So user has to wait till full page gets loaded and thats irritating . Was this the reason MVC was evolved?
Solution :Should i use partial rendering on all pages including home page, and all forms getting called from home page.
So even if half page is loaded thats less frustrating
For Partial rendering what i plan is : i will put Scriptmanager with Enable partial renderingand update panel for half part of page.
So that user dont have to wait for full page to load.
Is my plan correct? Problem is i cannot regenerate page load issue every time.

View 3 RepliesI made two web user controls that i want to show on web form. On web form there is PlaceHolder.

Control1 somehow disappears. Here is piece of code:
PlaceHolder1.Controls.Add(control1);
PlaceHolder1.Controls.Add(new LiteralControl("<br>"));
PlaceHolder1.Controls.Add(control2);

I've noticed that page load time increases dramatically as you load up a ddlistbox with items. 10,000 or so results in a pretty much unacceptable wait time for my setup. The dropdown I'm trying to load is Airports - like all of them. What are some alternative UI solutions that give the user the ability to easily select any (literally) airport, but without a ginormous page loading time? (Currently the dd is keyed to the airport's 3 letter code, so it's convenient for the prepared user to just type the 3-letter code and have the right airport selected. The display is then set to code, city, country.)
View 7 RepliesI have some code I only want to execute the first time I display a form. With this in mind I created a class variable which I initialize the first time I execute page load.
public partial class CLVideoDefinition : System.Web.UI.Page
{
string videofile;
string first;
protected void Page_Load(object sender, EventArgs e)
{
if (first != "N")
{
I then select a value from a drop down list , but when it does the auto postback it executes page load but my class varaible has been reinitialized to null and will then execute the code I only want to execute on the first run. why my class variable has been reinitialized.

View 1 RepliesI have an ASP.net MVC 2 application that runs well locally. However when I move the files to my production server, I get a first time lag of about 30 seconds, I assume this is a first compile. After that the application works fine. Then after about 20-30 minutes of non use, the applications takes another 30 seconds or so to load.
I did try to precompile the code, but there is still a lag during the first load.
Are there any trick to getting the application to work faster on the first load?

I am having a Gridview which takes much time to load its data, I tried to make the loading faster by implementing paging in gridview and reducing the rows to render in the grid and it got worked to an extent but still it lags in processing to bind data.

DataTable dtProducts = objProducts.GetProductDetails(iCat.ToString(), userId);
dgrdProductList.DataSource = dtProducts;
dgrdProductList.DataBind();
public DataTable GetProductDetails(String CatID, String UserID)
{
DataAccess DAB = new DataAccess();
DataTable dtbProducts = new DataTable();
try

string SQL = "select *,CAST(ShortDescription AS varchar(200)) AS ShortDescriptionList from vw_products where IsActive=1 AND CategoryID = " + CatID +

" PW_UserLangRel ON PW_Language.ID = PW_UserLangRel.LanguageID WHERE PW_Language.IsActive=1 AND PW_UserLangRel.CompanyID=" + UserID +
" ) Order By ID Desc,LanguageID";
dtbProducts = DAB.Fill(SQL, CommandType.Text).Tables[0];
}
catch (Exception ex)

throw new Exception(ex.Message + "WebShopPaolo.CProducts.AddProductImages");

View 4 RepliesFor some reason it takes 7 seconds to open a connection to a sql server database for the firt time, subsequent connections takes a second.
I'm using C# and asp.net
Its after compilation, i essence every time i restart the site, which means every time it needs to actualy create the "first" connection. i understand that setting up connection pooling has overhead, but i have never seen that i should take 7 second to set it up.
