Not to Display Blank Fields from Database

Apr 05, 2012 09:03 AM|LINK

Hey guys,

How is it possible not to display blank fields from a database. I've got tags associated with a post and they show up on the page but as a blank area. So if I have 5 blank columns in the database it will show 5 empty spaces in the tags.

Here is an example of what I'm talking about, scroll down to the first post: http://darvinkmanwah.com/default.aspx

If you hover between the tags you'll see orange lines, that's because of the CSS styles but it's pulling blank containers from the database. How do I close that gap and not display those empty containers?

Thanks for the help in advance ..,.

You can use where clause while accessing those tags from db. Only access where the values in those tags are not null and not empty spaces. If you can post the structure of the table, it will be easier to post exact solution.

Please Mark As Answer if it helped.

How do I close that gap and not display those empty containers?

In fact，as far as I see——I think it's time for you to ignore these gap by not setting or binding CSS to them。Maybe you can tell whether the bound value is null or empty——if yes，set its style as display or visibility:none。Maybe something looks like this：
```
<div style='<%#Eval("BoundFieldName").ToString().Equals("")?"display:none":"display:block"%>'>
   
</div>
```

Hey,

I'm glad to be back to the forum and working on my site again. I was wondering, is that piece of code written properly cause it's showing as though it is not formed properly. Here is my updated version but I'm not sure if it's correct:
```
<div style='<%# Eval("Work-in-Progress").ToString().Equals("")?"display:none":"display:block" %>'>

</div>
```
Thanks ...
