Im trying to change the information on each row depending on the result from the query. Im thinking that at the minute my problem is that I'm only returning the first result from the query into the result.
e.g. query returns row 1 with '1232' row 2 '1243' but result is only ever set to '1232'
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

View 2 RepliesI was wondering if anyone could help me. I have a template field which has four itemtemplates that each hold a label in a gridview. These labels are always constant with the same strings. What I want to do is change the css formatting of these four labels depending on the value of a column. So the css formatting would have to be done for each row, not the whole column. I bind the gridview to a dataaccesslayer so there is no sqldatasource on the page. Does anyone have any idea how to do this and where it would be done. I will have the dataview with the data sorted in the correct order. The actual column that is used to alter the CSS will not be in the gridview although I could assign it to the datakeyname if that makes it easier as the data is not sensitive.
View 1 RepliesI 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?

View 3 Repliesi have a database with a field for 'hasimage' with values true/false.

currently i have a single static image which takes user to the url.
code aspx:
<a runat="server" id="hlkmail">
<img src="../images/send_mail_icon.jpg" alt="" /></a>

<a runat="server" id="hlkmail"><img src="../images/send_mail_icon.jpg" alt="" /></a>
<a runat="server" id="hlkgallery"><img src="../images/galleryl_icon.jpg" alt="" /></a>

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.
