I have an active server page with a table using dynamic data. I want to put a condition on one of the cells so that if it is empty it will have a red background. Anyone any tips on how I can achieve this?

[stevie21]

In the "td" tag put an if statement.
If your dynamic data = null (or even if length of your variable name = 0) then
response.write "style='background-color:red' "
end if (close td tag and write the table contents, possibly as a non-breaking space)

It'd be tidier to use a css class instead of this "style="


Does this make sense?

stevie21 thanks for your answer,

Is it possible you could post the correct coding eg.

<td><if Recordset1.field1 = null then response.write "style='background-color:red'" endif>

<%=(Recordset1.Fields.Item("field1").Value)%></td>

This code is not working for me. What have I done wrong?

[stevie21]

Firstly, you've instantly closed the "td" tag : the if statement needs to be inside it.
Just for simplicity, if we can call your recordset field value "Kerplunker", then the code would be either

<td <% if isNull(Kerplunker) then
Response.Write "style='background-color:red' "
end if %>
>
One line up from here, OUTSIDE the if statement, the 1st td tag is ended. Otherwise you'd have
<td style='blah'
rather than
<td style='blah' >

Or you could start the asp with
<% if len(Kerplunker)=0 then ...

Finally, you could also
Response.Write "class='someClassThatHasRedBackground' "
if you're using stylesheets.


FINALLY - if Kerplunker is null then in the table cell contents you may also want to have
if isNull(Kerplunker) then
Response.Write " "
else
Response.Write Kerplunker
end if

I think empty table cells look odd if they don't have this nbsp code.

[stevie21]

In my FINALLY bit there, the first Response.Write should have the
(ampersand symbol) nbsp (semicolon)

This would all come after the first "td" tag is opened and before the other "/td" is closed. You could append </td> the end of each Response.Write here, or just have one </td> after the "end if " :

end if%> </td>

Excellent, thankyou very much for the help. I am pretty new to this but am picking it up slowly.

Thanks again.

I'm still picking it up slowly ;-)
