Display Large Photo From Thumbnail
Feb 17, 2011
I am creating a website where users can upload a profile picture. When a photo is uploaded I am resizing it and generating two new files one for a thumbnail view and one for a large view. Both photos are stored in the same folder and the file names are stored in to two different columns in an SQL table against the users membership account. The two new files use the following naming convention:
Random_name_small.jpg
Random_name_large.jpg
I am then using a grid view with a custom template and an image button to display the Random_name_small.jpg. What I would like to do is when some clicks on this thumbnail photo to then display the associated Random_name_large.jpg. From the SQL select command I am reading both the Random_name_small.jpg and Random_name_large.jpg and then binding Random_name_small.jpg to the image button. Can this be done using the details view or should I be rewriting the code manually to display these images.

I am creating a gallery of thumbnail pictures and when a user clicks one I need to show the full image. What I was going to do was on click set a varible for that picture and open ViewImage.aspx what would load that image big until I discover and ImageBox doesn't have a click event. Whats the best way of acheiving showing a large image simply from clicking a thumbnail?

I have a ModalPopupExtender control inside accordin control, users can add images, that I sotre the path in database(sql server) and the actual image in physical address inside web server,I automatically resize the image to thumbnail size in C#, when users first connect to the site,the see the thubmnail version of the image,which is much faster to download,and by clicking the thubnail, the hidden asp:pnael is shown with imzge in full size, I use javascript to unhide the panel and also change the image source to actual image,everything works fine in IE, but in Firefox and Chrome, the first time user clicks on thumbnail can not see the full size image,only after couple of time, they see the full size image? what could be the problem?
I am using asp.net ,C# what is the best way to achieve this?

I have an Image control on my page that should display a thumbnail preview of the actual image. The URL property of this control is assigned through the code-behind using:
imgHolder.URL = @table.Row[0].ItemArray[0].ToString();
Before moving my files to another location, this assignment works fine (The files used to be located inside the application folder). But after moving all files to another drive in the same server, the images don't seem to render any longer. I can upload/download files fine but they just won't display as thumbnails on the page.

A user will upload the images through FTP in the images folder. So my requirement is when he clicks on the link say for eg [URL] all the images should be displayed in the thumbnail format. What I did is I opened the IIS and over there I selected the directory listing. So when I click on the link [URL] it shows the list of images. But I want this in the thumbnail format.

i am facing a prblem about image resizing.. i know it is a common problem but the scinario is little different here. i have some image in my server image directory and also have their small 128 X 128 sized thumbnail..i show a page with those images like 'facebook photo album' and also linked another page to display them..when a picture is clicked it refferd to that page and that page loads the full sized original image along with picture comments bla bla..., the page width is fixed to 1024px, and the div's width is 800px max which contains the <asp:image..../>; that shows the full sized image. here the problem comes, when a original sized picture is greater that 800px then the remaining part of the picture is croped !! i know it will happen.. that is why i planned to show a thumbnail like pic which's size will be 800px max and link the page with a pop up java script page which will contain the full sized picture only. the problem is i can't resize the picture in a limit of 800px on fly.

I need to create a thumbnail solution in order to display pictures of products.
There can be more than 1 thumbnail per product and I need a way to enlarge the image as well.
The thumbnails will be displayed in atleast 3 or 4 pages across the system and I need the ability to delete them as well.
For version 2 of the software (knowing PM's it may be thrown into Version 1), I think I will need to be able to enhance this feature to allow movie clips so that's something I need to keep in mind.
The images will be stored in the DB so I can sort the code to retrieve them but I'm originally a windows programmer and this is my first major ASP.NET project and also my first attempt at C#.

I've got:
<asp:HyperLink ID="HyperLink2" runat="server" NavigateUrl='<%# "PropertyDetails.aspx?propertyId=" & Eval("propertyId").tostring %>'><asp:Literal ID="Image1" runat="server" Text='<%# Eval("imageId", "<img src=""images/properties/{0}_thumb") %>' /><asp:Literal ID="Image2" runat="server" Text='<%# Eval("imageFormat", "{0}"" alt="""">") %>' /></asp:hyperlink>
which displays an image from my db.
However, if there is not an image - e.g. if my property record doesn't have any images associated with it, I would like to display a default thumbnail.

I 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.

we have a classic ASP Webpage for displaying reporting data.
The process is following:
user inputs reporting criteria reporting criteria are passed to a method in a VB6 DLL containing the reporting business logic (generating a dynmic sql statement) VB6 DLL method returns xml data xml data are displayed with xsd transformation 150.000 datarows are displayed in some seconds (less than 10 seconds maybe) Now we want to extend this reporting function and decided to use asp.net (2.0) So I have written a little prototyp application with a SqlDataSource Object and a GridView Control.
A table with less data (about 100 or so) are displayed quickly.
But a view with about 150.000 datarows needs about 2 minutes and ended with a OutOfMemoryException!
The request of the customer is definitvely to display the data on one page like in the old classic asp application!
