Web Forms :: Uploading And Retrieving Image To A Image Control Doest Not Work?
Jun 22, 2010
I have a problem about image control. I am using VS2005 in Vista and suddenly uploading and retrieving image to a image control doest not work. I am working with this in Windows XP and all goes fine. After transfering it to vista, I can't upload and retrieve an image stored in the File System. My codes are all the same.
I Used AsyncFileUpload(one of Ajac Control Toolkit Controls) to Uploading User's Image. this works well. But i want to change the image url of an image contorl to uploaded image url. how can i perform that? I put Image control in a Update Panel:
[Code]....
in C# code I wrote these:
[Code]....
But it does not work. Image is like Previous. Note that ImageOperations.ResizeFromStream() method resizes and saves the image to a specefic folder. actually I should trigger a Postback to Update the Update Panel but How to do that. I usedUpdatePanelNew.Update(); but it does not work!
i am working on an ecommerce application, user will be uploading several images of a product, instead of stripping the size (i.e the KB or MB size) after uploading it on the server, i want to strip the size of image before uploading it to the server ( bringing the size from any thing over 30KB down to 30KB) i.e on the client machine itself and then upload it to the server. i understand that this requires a download on the client machine which makes me ask the following questions :
a. can i use a java control in dotnet since java control can be used on all OSes b. is there any dotnet control that might be userfriendly to all OSes
I am trying to put a default image in an Image control in asp.net and it should show that particular image on the page when no other image is assigned or no image available in Database.
I know how to display an image in gridview from image path in database. Now, I want to display an image in an asp.net image control from image path in database. Can anyone point me to a tutorial? I haven't been able to find one that explains how to do it when I don't know what the image path will be. The images are in the root folder.
I am uploading an image with AsyncFileUpload, it works well, but i want to show to the user the image which him just uploaded, but i am having troubles to make that work.I have tried the OnClientUploadComplete event which receive sender and args paramenters, but the second paramenter only have the file name (without relative url), lenght, but not the file name after saved on the server.I also tried ScriptManager.RegisterClientScriptBlock and call my own function in order to pass the url, but for some reason i can't select the img control with jquery, seems like that peace of code is executing in another instance of the page... not sure.
I am converting a html pages into aspx. There are images flashing along the top of the webpage using javascript control. But it does not work after i put into the master page.
In the VB Developer Express, there are also green underline for class name (i.e. class="back")
I'm not even sure if this is the correct approach for this -
I have a DB that stores information, as well as a location to where images are stored
ie ProductImage = ~/ProductImages/BulkRetail.JPG
I'm using a repeater to list all the products, which works fine for all the labels I use but not for the image location. I'm using something like this, but it doesn't work:
i have a website which has a <IMG> and/or <asp:Image> in it.
The user has an option to upload an image. so if the user does upload an image it will be displayed in the stated controls above. but if they don't the control displays its alternative text or an "x" icon. can i just place a default image in it if there is no image reference to it to display?
I have developed simple application to display the image to my page . i had declared the image control in design page but i have assign the imageurl in codebehind . when i run this page in IE is display the image but when i ru the same page in mozilla and chrome it won't display the image how to fix this problem or anything i have to add in codebehind.
I am working on a website, using C# with a SQL backend. I'm using the Varbinary data type to store my images because the Image data type is eventually going away. I got the images into the DB and can pull them back out to display on the website. My question is how can I put the images from the DB into an Image control on the website? The images will be different sizes, so I need to keep them confined in one space on the site. I also need to randomly display the images, one at a time, on the website. The user needs to be able to hit the Next button to see the next image when they are ready. The user will only view the images, not make any changes and send data back to the DB.
Since the image will be confined within the image control, how can I allow the user to click on the image and open in a new window? The image needs to be bigger to allow the user to see more detail. Or would it be easier to allow the user to zoom in on the image within the current window?I am using VWD Express, C# 2010 Express & SQL 2005 Express.
I'm no expert with Image controls, or dynamically adding anything, but I seem to have some problem when dynamically adding image controls
When the page loads the images are "there", but they don't actually show an image...just an image "box" I guess you could call it. It's not the "broken" image or "invalid" image display, but a friendlier one that doesn't make sense to me why it's there.
I look at the page's source and literally everything's fine, but I'm not sure what's going wrong. I can show you my code, and hopefully someone will point out the dumb thing I'm doing wrong:
[Code]....
[Code]....
So, it takes all the .JPG files in the folder "Pictures" of my project's folder and creates an Image control to be put into Panel1 with the ImageURL as its filename (with Directory Path) and even set the ID to its filename (so no duplicate IDs). Again, the source is exactly how it should be, but no image is shown.
Me with C# asp.net. In my sqlserver database table I have 2 fields Id and Imagepath like
Id Imagepath
1 images/car1.jpg
1 images/car2.jpg
1 images/car3.jpg
2 images/car4.jpg
2 images/car5.jpg
On page1.aspx I have a text box and a button, on entering 1 in textbox and on button click load, I want to show page2.aspx and all the images with Id 1 (ie car1.jpg,car2.jpg,car3.jpg) should be shown. How can I show like this with out placing image control by default in page2.aspx because number of image varies ie if I enter 2 I want to show only 2 images.
look at the picture, i want that image preview will come when i choose the file location before uploading to the database. is it possible?
EDIT: i found codes in other sites, they say those only work in IE, so it means currently, this preview function doesnt support FF? coz im using FF or sometimes google chrome.
