ADO.NET :: Dynamically Image Displaying In Liq To Sql?
Nov 10, 2010
I try to establish a dynamic HTML table with data for an item. i am getting trouble showing the image for the item, i am getting my data from the database, i have saved my image as image in the database, and i used byte[].
I have the following code for desplaying data:
protected void DDLitem_SelectedIndexChanged(object sender, EventArgs e)
{
var item = new ItemControl(); // this is in the BLL layer.
List<Goods> get = item.returnGoods(DDLGoods.SelectedItem.Text); // DDLGoods is a DropDownList. and the method returns a List<Goods>
var out = new StringBuilder();
out.Append("<table><tr><td>Name:</td><td>Designation:</td><td>Price:</td><td>Item Number:</td>");
foreach (var v in get)
{
out.Append("<tr><td>" + v.name + "</td><td>" + v.designation + "</td><td>" + v.price + "</td><td>" + v.itimId + "</td><td></tr>");
}
out.Append("</table>");
Label1.Text= out.ToString();
}
I need to wrigth in the foreach loop somethink that will desplay my v.image.

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.

Here is this thing which to me looks possible, but when I searched over the net I couldnt find anything.
I want to create a page where I can upload an image using any upload function and then display it. Now after diplaying it I want to select the hotspots for an image map. The coordinates of image map values are stored in a database.
Basically I want that to create image maps and hotspots I dont use any offline software, this work is successfully completed and working perfectly, but i want generate one identification where i click the hot spots position in image or CSS file Generate for user identifications, So how can i solve this problem.
I hope You are clear in that what I am looking for.

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 want to create a page that will dynamically change the images displayed, based on which link the user clicked to get there. For example I have different movies listed and when you click a link for one of them it displays all the images for that movie. I need it to be on one page because at the moment I have hundreds of pages and its very hard to manage. I have the images stored in BLOBS on SQL Server 2005. I can retrieve all the images for a certain category and store the Image data for each one into a list of images. What I cant do, is display the images on the page. I can display one image by using the queryString to get the image by ID, then putting the Eval code into an asp:image, but I dont know how to do it for multiple images.

Situation: I have a drop down list which I need to pass on to a webservice on button click. I am using Sys.Net.WebServiceProxy.Invoke to make webservice call.
Everything is happening inside a usercontrol which loads on runtime using dynamicpopulate extender.
I get following error:
Sys.InvalidOperationException: Cannot serialize object with cyclic reference within child properties.
Situation: Usercontrol also has a listview which is bound to dataset. However on calling listview.DataBind() in side the webservice method.
I get following error:
The ListView control 'ProductsListView' does not have a naming container. Ensure that the control is added to the page before calling DataBind.
There is no problem when call to service method is parameter less and listitem is not bound.

Objective:

Problem:
I have stored the the pdf uploaded as byte[FileUpload1.FileBytes] using "image" datatype in database. My problem now is to retrieve the binary data and decode to a pdf. I followed the code in the article [URL], which lets me to download a file, but when i tried to open the pdf it showed me error.
"adobe reader could not open test.pdf because it is either not a supported filetype or because the file has been damaged (for example it was sent as an email attachment and wasnt correctly decoded)"
More than download, I need to display the pdf.
