I have a gridview which displays rows and columns all linked to an sql statement... and all works as normal.
I want to include a new column, that displays an image depending on what the value of the column is. If the column has a value - it will display an image. If the column value is null no image whill be displayed.
My sql is something like:
SELECT c.call_id, title, a.call_id as b_attach FROM calls c LEFT JOIN attachments a ON c.call_id = a.call_id GROUP BY c.call_id,title,description, a.call_id
What's returns from this sql is:
Call_id | title | b_attach 1235 | title goes here | 1235 1382 | another title |NULL
So if there's something in b_attach - diplay image in gridview column, else display nothing in gridview column
I have a gridview and would like to display one of 5 icons depending on the value returned from the database for that row (simply just A, B, C, D or E). Which event in my datagrid should I be looking at to check what value I'm getting? I presume once I can check a value I can simply set an image source using if statements?
i have 2 tables assignment and feedback, in a gridview it displays all the assignments, the assignments then get feedback. im then wanting to change the view feedback button in the gridview depending on if there is new feedback for example:
the feedback table has a state field in it so when its 1 i want that image button to change to the one with the +
I am in the process of moving all of the images in my web application over to a CDN but I want to easily be able to switch the CDN on or off without having to hard code the path to the images. My first thought was to add an HttpHandler for image extensions that depending whether a variable in the web.config (something like ) will serve the image from the server or from the CDN. But after giving this a little though I think I've essentially ruled this out as it will cause ASP.NET to handle the request for every single image, thus adding overhead, and it might actually completely mitigate the benefits of using a CDN.
An alternative approach is, since all of my pages inherit from a base page class, I could create a function in the base class that determines what path to serve the files from based off the web.config variable. I would then do something like this in the markup:
<img src='<%= GetImagePath()/image.png' />
I think this is probably what I'll have to end up doing, but it seems a little clunky to me. I also envision problems with the old .NET error of not being able to modify the control collection because of the "<%=" though the "<%#" solution will probably work.
I have a fileupload control in a contentplaceholder in a masterpage. I have to preview the image whenever I browse an image beside it in an imagecontrol.
My application is running on a different server .So I can't give the filepath of my local system.
Also I don't want to store the image in any location and i'm not supposed to use any session variable to pass it to generic handler.
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 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 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.
