Web Forms :: Displaying An Image From Code Behind?
Mar 1, 2010
I have a list basically built with some html and javascript code.. I want one of the columns to display a picture if a certain object in a <List> is null. I have to do this if statement in the business layer. How do I do this?Here is the code for when i just display "Yes" isntead of a picture...
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 a newbie to Asp.net,learning from the Apress's Begining Asp.net...book.While very curious to see an image given by me on the browser,I'm stuck at the very first step,Configuration : Win7(32-bit),VS2008 Pro/.net 3.5,Firefox as default browser.Now,In created a simple website(not web app) in C#,added three images(.png,.jpg,.gif) to the App_Data folder(using the solutn. explorer of course).Then added the Image control from the toolbox & in the ImageUrl property, selected one of the images->presses f5 to start in debugging mode but every time the browser displays the alternate text given by me.
Tested my method by assigning the String(containing my image's path) returned by it to a label..its getting the path alright..then why wont it display when I run the code?when I viewed the page's source..this is what I see..
I can do the above by placing the relevant .jpg into the VWD project.
However, I would like to be able to to do this without adding the image file to the project.
e.g. In code, get the image from C:/images/NameOfImage.jpg
The reason I am trying to do this is the website will allow the user to upload as many images as they like. Each one's details will be stored in a database, including details of which location they have uploaded the image to. On retrieval, I will get the location of a specific image from the database, and display it on the page.
I have stored image path in database. While displaying I have to get the image path from database and set it as the ImageUrl of Asp.NET Image control.But it is not displaying the image. below is the code of that.protected void Button1_Click(object sender, EventArgs e)
I have a modal popup extender with an asp:image control, and 2 buttons.
I have tried to load the image from a file on the local project folder which I have dynamically created through serverside code, but it will not display the image however I tried.
here are the codes of the modalpopupextender and the hidden popup panel:
I'm using varbinarymax.....IN SQL gridview image and setting the nullimage value doesn't this problem.. I'm looking for code that can make this lil miracle happen
& it doesn't really matter which way , whether the code says if image null then display this image from ~/Images/thispic.jpg or if i1 display this image from ~/Images/thispic.jpg for a little bit more insight into this I'm creating a legend for the database and the null has been used for displaying one pic so i'm after the 1 or visa versa to display another image.... and i'm not trying to upload pics to 1000 plus documents, and when i came at it from a sql angle tying 5 tables together the parent table ended up not sending the proper return. is this even possible or am i ahead of visual studio
I am building an upload page for photos, and would like to preview the image once uploaded. I have looked at a few posts but have not quite reached a working solution.

I have a byteArray which I can only convert into an Image (Drawing.Image) I was wondering how I can display it a webpage. I used memoryStream as I dont want to user to have to download the image. Eventually I will use this to display images in google maps.. I can convert it into a graphic but once again not sure what I will do with it. The Error I have been getting lately is Cannot implicitly convert type 'System.Drawing.Image' to 'System.Web.UI.WebControls.ImageField'
I am unable to figure out the best way of handling the following scenario. So far I have just been messing around with the code trying to get all these pieces to fit together.
I have a multiform view, and within one of those views I want an image to be displayed that is created on the fly based on data from a database, though I have hard coded the values to at the moment, I'll add the database piece later.
I load two images as bitmap objects, add the smaller image onto the larger image, then write the new image to a file as a jpeg. I then load the jpeg into the view controller
[Code]....
First question, I really do not want to create a temporary file. I have tried several different pieces of code to convert the bitmap object into an image I can load into the web controller, but have failed.
Second, I need to set a hotspot in the image that is being displayed in the multiview View2, and I am not able to do so. Is there an easy way of doing this, or should I call the above code as part of an ImageMap, where I can easily set the hotspot? If so, how?
I realize this is kind of a convoluted post, but I am at a cross roads and not sure which direction to go.
I derive the list of images as follows have a drodown list which contains the possible filders. The user selects the folder and clicks a button to display the images. On the button click I get the contents of the folder using getfileinfo|(0 and add the details to a datatable. I create a field in the table that contains the path and the imagename (fieldname imagePath)
