Web Forms :: Displaying An Image Within An Image Control On A Website From A SQL Database?
Oct 19, 2010
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 am trying to display an image from "C:emp". Here's the code:
string root = "C: emp"; string[] files = Directory.GetFiles(root); foreach (string f in files) { if (Path.GetFileName(f).Contains(user.WorkEmail)) img1.ImageUrl = root + Path.GetFileName(f); } }
If an image is not found, I get a thumbnail with a red "X" - fine, as expected.If an image is found, I get a thumbnail but no image gets loaded/displayed. When I right click the thumbnail and go 'Properties' it shows the correct filename.
I have div In my page that in this div I put image control
<div id="DLogos"> <asp:Image ID="imglogo" runat="server" CssClass="ILogos" /> </div> according to below code <div id="Dart1_I1" visible='<%# !string.IsNullOrEmpty(Eval("image1").ToString())%>'>
If in database was image it show div and if there wasn't any image it didn't show div but above code is for div that I put in datalistnow I want do some thing like that for Div that I don't put it in datalist I should write code for that in behindecode page but I don't know How I can do it?behind code
SqlCommand _cmd = new SqlCommand("storeinfo1", _cn); _cmd.CommandType = CommandType.StoredProcedure; _cmd.Parameters.AddWithValue("@behcode", data); _cn.Open(); SqlDataReader _dr = _cmd.ExecuteReader(); while (_dr.Read())
I need displaying my image file stored from my database into the image control. I've had read some articles and watch video tutorial which there were perfectly working and I followed it but I wasn't able to make it work. The image control just displayed blank.

How can I display photogarphs in an image control so that they are all the same size for an online catalogue without distorting the actual image.
I have taken the photos with a digital camera, loaded them in to Photoshop, cropped the image and finally resized the images to an acceptable size (while constraning proportions to avoid image distorsion).
The problem is that the images all have different height dimensions as while resizing i was able to choose the width that I wanted but as I had to constrain proportions to avoid distorsion, it caused the heights of the images to differ.
On my web form I have an image control that is set to the same width as the images but as the heights of the images differ from one and other, it is impossible for me to set a fixed height that will prevent some of the images being distorted when displayed in the image control.

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..
