I have a gridview which displays data for all employees and their images (stored in database).
The images take more time to render completely when i click sort or paging or reload.
I'm using httphandler to display image as stream.
Is there a way i can speed up this image loading?
i have a gridview with 1 image colums
i want to be when loading images columns show a gif image.
I am trying to find the best way to have a page with a lot of data from queries to a database load faster. Looking at [URL], when viewing information about a domain, I see that their page loads and each section has a loading symbol, so the page itself displays fast and the data comes when it is available. How do they do this? Update panels around each section with a call to a Web Service? Also, Google AdWords seems to do this too when you load the Ads or Keywords tabs of a Campaign.

Basically what I'm doing right now is loading them from the server and displaying them in image tags. Problem is this crashes the browser. In chrome it will crash, in IE it will bog the computer down and lock it up. I think the browser is running out of memory or something.I'm wondering if I should be using a background worker or a different thread or something.. Is this possible with a web app?
I'm using Crystal Reports in a Webform inside of an MVC application. Images in the reports are not being displayed, however, on both the ASP.NET Development Server and IIS 7 (on Win7x64).
I know from a number of other questions similar to this that the CrystalImageHandler HTTP Handler is responsible for rendering the image, but I've tried all of the usual solutions to no avail.
So far, I have
Added the following to my appSettings (via http://www.mail-archive.com/bdotnet@groups.msn.com/msg26882.html)
<add key="CrystalImageCleaner-AutoStart" value="true" />

<add key="CrystalImageCleaner-Age" value="120000" />
Added the following httpHandler to system.web/httpHandlers (via http://stackoverflow.com/questions/2253682/crystal-report-viewer-control-isnt-loading-the-images-inside-the-report)
<add verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=12.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
Added the following to my Global.asax.cs (via http://stackoverflow.com/questions/2006011/crystal-reports-images-and-asp-net-mvc)
routes.IgnoreRoute("{resource}.aspx/{*pathInfo}");
and
routes.IgnoreRoute("CrystalImageHandler.aspx");

View 1 RepliesI had to move an asp.net website from Windows 2003 to another server with Windows 2008. Now when I run the website after setting everything up the images will not load. It is a logo that is in a folder named Images. The file is there along with the folder just like on the other site. Any reason this would not work now? Everything else is working except images. Is there something else I missed in the setup?

I have a set of images which are subjected to display inside a usercontrol(horizontally) but while loading the page the images are displaying vertically. Only after the page completely loaded they are displaying properly. How can I use jQuery to hide the images when the page is loading and display them when the page is fully loaded. Below is the usercontrol code I am using for displaying controls:
[Code]....
I'm creating a simple CMS for a fairly simple web page. I'm currently working on a part for displaying news on the main page.
The controls I have on the page:
- a GridView control with enabled pagging and a SELECT button,
- an Image control for displaying news cover picture,
- CKeditor control for editing news text,
- Repeater control for displaying pictures from database
How does it all work?
In Page_load I have the following:
vb.net Code:
connectionString = "Data Source=KORISNIK-PCSQLEXPRESS;Initial Catalog=****;
User ID=**;Password=****" conn = New SqlConnection(connectionString)
If conn.State = ConnectionState.Closed Or conn.State = ConnectionState.Broken Then
Try conn.Open() If Not IsPostBack Then bindGrid()
[Code] ...
As you can see, I load the GridView control with news from DB. At this moment all other control are disabled. User has to SELECT the row he wants to edit, and click the MODIFY button.
This is what happens when user clicks the MODIFY button:
vb.net Code:
Private Function selectForEdit() dsSelectForEdit = New DataSet
captionPicture.ImageUrl = "" enableCommands()
Dim sqlQuery As String
sqlQuery = "SELECT news.newsCaption, news.newsIntro, news.newsCoverPicture, news.newsStatus,
[Code] ....
Basically, I select newsDetails based on newsID. Also, this is where I take the coverPicture from the database using a generic handler.
This is the code for showImage.ashx:
vb.net Code:
Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
Dim newsID As Int32 If Not context.Request.QueryString("newsID") Is Nothing Then
newsID = Convert.ToInt32(context.Request.QueryString("newsID")) Else
Throw New ArgumentException("No parameter specified") End If
[Code] ....
This part works fine, as the picture is correctly displayed in the Image control. Now, I also want to load the pictures that are related to the selected news. So, I use this function:
vb.net Code:
Private Function selectNewsPictures() dsSelectPicturesForEdit = New DataSet enableCommands()
Dim sqlQuery As String sqlQuery = "SELECT newsDetailsPictureID,newsDetailsPicture,newsDetailsPictureCaption,newsDetailsPictureDescription FROM newsDetailsPictures WHERE newsID = @newsIDEditing" myCommand = New SqlCommand(sqlQuery, conn) myCommand.Parameters.Add("@newsIDEditing", SqlDbType.Int, 250)
[Code] ....
You can see that I take pictureID's and store them into a List (of integer). That way I can use those integers in showNewsPictures.ashx to display all the pictures.
showNewsPictures.ashx:
vb.net Code:
Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
Dim newsID As Int32 If Not context.Request.QueryString("pictureID") Is Nothing Then
newsID = Convert.ToInt32(context.Request.QueryString("pictureID")) Else
Throw New ArgumentException("No parameter specified") End If
[Code] ....
The picture ID's are being sent through pictureRepeater_ItemDataBound:
vb.net Code:
Private Sub pictureRepeater_ItemDataBound(sender As Object, e As RepeaterItemEventArgs)
Handles pictureRepeater.ItemDataBound
If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
Dim ctrl As New Image ctrl = e.Item.FindControl("pictureHolder")
ctrl.Width = 100 ctrl.Height = 100 ctrl.ImageUrl = "~/showNewsPictures.ashx?pictureID=" &
listOfIDs.Item(itemIndex) itemIndex = itemIndex + 1 End If End Sub
THE PROBLEM:
I load the page, select the news, click the MODIFY button and all works well. The news details are loaded, the cover picture is loaded, the repeater pictures are loaded.
I click the cancel button (clears all the commands and disables them) and I get an error saying the DataReader needs to be closed.And I never use one This happens either in showNewsPictures.ashx or showImage.ashx.
In some other scenario, this happens right after I click the MODIFY button.
I have a website using Telerik controls for ASP.NET. When an AJAX request starts, the Loading Panel (defined in the master page) will display, with a loading image, text, and faded white background color. It works totally fine in Firefox and Chrome, but the background image and text don't display in IE8. All that displays is the white background.LoadingPanel code: Loading ideas why IE8 isn't displaying the images? I've inspected the page source, and they're there in the CSS.

View 6 Repliesi have implemented an image preloader using javascript inside my mvc 2 web app, in order to display an animated "loading" image .gif while sequentially displaying page images.I have also implemented caching using a cache profile for the controller action that displays the specific page ([OutputCache(CacheProfile = "LongCache")]).The problem is that the image preloader javascript is called when caching is applied. I was wondering whether i could, somehow, use the image preloader code only when the page gets refreshed and not when the cached version is rendered.

I recently upgraded from VWD 2008 Express to VWD 2010 Express. A problem has developed in that the website's graphics no longer appear in Design mode, there are "Error Creating Control" error messages that did not exist before, and also debugging errors that did not exist before. (Note: these problems did not exist when I first used VWD 2010; they may have originated with recent automatic Windows updates (I use Vista Home Premium SP2 with IIS 7)). The problem exists if I open the website either as a project file or as a website directory.
