Forms Data Controls :: Retrieve An Image From DB And Display It?
Aug 14, 2010
I am having a problem displaying an image in the fileupload tool.
This is it. I have an image upload tool and also have a VARBINARY field in the database to save the image. during the save process I add the uploaded image into the database VARBINARY field. This is how i add it.
DR["IMAGE"] = FileUpload1.FileBytes;
It saved successfully without no errors. Now after saving i need to display that image in a ImageBox control which is available in my web form. How to display an image which is saved as VARBINARY in the database into an image box?
I'm amazed that it took me minutes to figure out how to retrieve text from a specific SQL database record and display it on my aspx page using FormView---and yet days later I still can't figure out how to retrieve/display the corresponding database image...(I feel like I went to a fast food restaurant, received my burger and drink in minutes---but for the fries I'm told to leave the restaurant, drive to another county, and search for the granite boulder under which I am to find the next clue in the quest to get my fries.
I don't want to waste anybody's time---I do see that this issue has come up here before (but each solution seems more complicated than the previous one): clearest way (or your favorite past thread on this topic) to retrieve/display/edit binary image data using FormView?
I am trying since more than 5 days to retrieve and display an image in a web page, no success so far.1. I have a table named image, with three fields ImageID, Img_data, Img_contenttype .2. I am able to display the ImageID as a link in my page.3. On clicking the link i am going to my viewImage.aspx?img=ImageID .This far it works ok. ImageID is passing in the query string.4. In this page imageID is being captured from query string and stored in ImageIdview int variable. viewImage.aspx has an image tag to display the image as below.
I know this might sound like a simple quesiton, but I am having problems allowing me to upload images along with other information (name, image, biography, wbsite links) to a sql server database, as well as showing images from the database using a drop list control feature. I am using [URL] for hosintg. VB language.
I have a page which displays details and a pictures of employees. The details are stored in a SQL database and the images are on the server. How can I set a default Image to display (e.g. an Image saying "Awaiting Image") if an employee picture is missing?
I can't use NullImageUrl as the Images are not stored in the database. I can't use the solution found on [URL] as an ImageField does not accept an ID attribute.

I have a method that retreives data from table and needs to display in details view. The method is give below: The problem I am facing is I did put some break points to figure out if all the lines are executed but the problem I am facing is that the compiler is not going in the while(reader.read()) loop(I have made to loop bold so that would be easy to locate) and hence unable to retreive data.
public static Workstation GetWorkstationByName(string workstationName) { Workstation computer = new Workstation(); string key = "workstation_workstation_" + workstationName; if (workstationName == null) return null; if (SiteUtility.Cache[key] == null) { string con = SiteProvider.Instance.AltirisConnectionString; List<Workstation> workstationlist = new List<Workstation>(); SqlConnection cn = new SqlConnection(con); SqlCommand cmd = new SqlCommand("Select [Server] from vComputer where Name = '@workstationName';", cn); cn.Open(); cmd.Parameters.Add("@workstationName", SqlDbType.VarChar).Value = workstationName; SqlDataReader reader = cmd.ExecuteReader(); while (reader.Read()) { Workstation ws = new Workstation(); ws.Server = reader["Server"] as string; workstationlist.Add(ws); } string ADSPath = "LDAP://" + SiteProvider.Instance.DomainString;..............
I have a page where I will insert all the data into the database. The page where I'm having problems is when I select an item from the checkboxlist it only displays one item. The data which is displayed is only the one that was inserted with one selected item from the checkboxlist. The following code is the page I'm using to try to retrieve the data from the database. I am trying to do is when a user selects the first, second, or third, or fourth item. The corresponding data appears in the gridview. In my current code, the record which has one item selected appears. If the user has more than one selected it does not appear. It comes up as empty. Is there a way I can do it?
I have data in mydatabase. My AnswerText in the database is test1,test2,test3 While retrieving it is displaying as test3,test1,test2. I am using the below code to display the data.

I want to display the AnswetText as test1,test2,test3. Basically i want the same order which i added to the database while retrieving also.
