Any tips on where to start looking/investigate Re how to code pages to only load/render images when that part of the page is visible ?
e.g. Recent Google Image Search and Facebook interfaces.
Up to now my Ajax experience has been limited to extensions + Toolkit so not sure where to start looking.
i am looking for some sample code in order to upload and/or retrieve images stored in a database.even the web is full of samples, i was not able to find one without using blobs as i would like to save only the directory of an image when it comes to the place of storing. the reason behind is that i do want to have my database small for some reason and therefore only want to save links to my images inside.
View 5 Repliesi have two buttons, which point to some onclick-methods in my code-behind file. inside these btn_click-codes i want to start adding pure html-code to my page, which was told to me in this forum having done by using ascx-files. note: there would be no code-behind in case of using the ascx-files.
however i do not see a possibility to load these ascx-files within btn_click-code? how to do?
in order to give you an idea of my html-code i have pasted two of them here:

maybe this is the complete wrong approach (as i.e. i believe that body-tags should not be included in .ascx-code). in this - how to do better?
how to do the below?

View 1 RepliesI'm trying to use the WebImage (included with in assembly System.Web.Helpers with MVC 3 RC2) class to manipulate images, like cropping, resizing, etc.... I've found that when using with PNG images with alpha transparency the result of the transformation is rendered with black background or with bad distortions; that problem happens only with transparent PNG, other file formats are ok.

View 2 RepliesI am build an asp.net website that has an Access database. We are using a DataList with a couple fields inside the ItemTemplate. The one that is giving me trouble is the Hyperlink. The code is below. When the page loads the hyperlink renders like this:

As far as I know server controls doesn't have a .aspx file. So I need to load a aspx file in order for it to work like a template for my server control, and render my server control content.
View 4 RepliesI am trying to use aspx pages as an email templates. There will likely be a bunch of objects on the page which will be used as replacements in the html. Because it's an aspx page I'll be able to use databinding, repeaters, etc. At run time, I want to be able to instantiate the aspx page from its path, pass in a bunch of properties, and then get the rendered result of the page and email it. This seems pretty straightforward from a asp.net website (maybe using BuildManager or Server.Execute.) However, I want to be able to use the same templates via a console application by just loading up a page object from its filepath. Is this possible?
View 1 Replieson my dev machine (windows 7 with II7) I run a asp.net 4 web site. The web site run under the Visual Studio ASP.NET development server.
The problem is that I have a page that should load images from an external server. To test this behaviour I have created a virtual directory under IIS and I try to connect to the image with the following link:
http://localhost/ExtJPG/20080723112946001.jpg
I tested the link from a browser and It worked well, but I'm not able to load the image from my asp.net application. The page begin to load for a very long time and finally shows the classic red cross. if I right click and select show image the image display well.
Using the code such as found below, sometimes certain .PNG files will fail to load. While other images, nearly identical in size, never have any such problem. Build Action set to Resource. Why is that? Anybody figure it out? This is for a datagrid but I doubt the control has much to do with it. Probably certain .png files make Visual Studio 2008 choke because of some attribute set internally. But it's a mystery to me....anybody else notice this? # private void dGrid_LoadingRow(object sender, DataGridRowEventArgs e) { Employee emp = e.Row.DataContext as Employee; FrameworkElement ele = dGrid.Columns[4].GetCellContent(e.Row); string url ="http://localhost:7642/DisplayImageHandler.ashx?id=" + emp.ID; Uri imageUri = new Uri(url, UriKind.RelativeOrAbsolute); (ele as Image).Source = new BitmapImage(imageUri); } private void img1_ImageFailed(object sender, ExceptionRoutedEventArgs e) { Image img = sender as Image; // Display an image for error here }

View 2 RepliesI have tested my pages in Firefox & IE and looking at Firebug in Firefox for some reason some images are taking a long time to load. They are not very big in comparison to the ones which are loading quicker.
Attached is a screenshot of Firebug.
I especially notice it in IE with the progress bar at the bottom of the page, it just sits there saying loading image...
Could it be the path or something which is http://localhost:49211/Content/_layout/images/bg-footer.png for example
We are planning to introduce Load balancing in our server environment. Our site has lots of thumbnails (Thumbimages) to get displayed on the website. As all the images should be there under Web directory to get displayed on web site, do I need to maintain these TNs in all the servers? Is there any other way to accomplish this?
View 1 RepliesI've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).
I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?
In my webpage I have 20 .jpg Images. Sometimes it can take about 10 seconds before the webpage is loaded and all images are seen.
I have one .jpg image that are more important to visually see first before the others.
So my question is if it is possible to "force" one image to load the Very first to be seen visually? I dont know if this works in a specific order or the webpage renders it by random?

I'm going to design a database for an image gallery in ASP.NET Web App . Because of some reasons I've decided to store the image in Data Base , Not the address .
In the application i need two or more different size and weight image for each image that the admin insert .For instance , One of them is small and lightweight thumbnail , and the other is Original big one .
My question is : Should i have two column ( one for lightweight and small thumbnail and one for big and full size one ) in DataBase Or Is there any way i could load different size and wight image from Big and original image column ?
