Changing field colors through broker

Jan,

Is it possible to access report fields from the broker in order to set their background color or other visual properties?

Thank you,

Igal

Hi Igal,

It depends on what exactly you're trying to achieve.

One method is to use a formatter helper function in your data broker, and use the 'htmlText' format on the data field. Such a formatter helper function could look something like:

Code: Select all

function formattedData pData
   local tFormattedData
   put "<p>" into tFormattedData
   if pData is a number and pData < 0 then
      put "<font color=" & quote & "red" & quote & ">" & pData after tFormattedData
   else if pData is a number and pData = 0 then
      put "<font bgcolor=" & quote & "yellow" & quote & ">" & pData after tFormattedData
   else
      put htmlSafe(pData) after tFormattedData
   end if
   put "</p>" after tFormattedData
   return tFormattedData
end formattedData

function htmlSafe pData
   replace "&" with "&" in pData
   replace quote with """ in pData
   replace "<" with "<" in pData
   replace ">" with ">" in pData
   return pData
end htmlSafe
and then your data field would have an expression similar to:

Code: Select all

formattedData(sCustomer["balance"])
If the customer's balance is negative, the balance will be printed in red; if the balance is 0 then the balance will pe printed in black with a yellow background. Admittedly a silly example, but quite a nifty way if all you need is to manipulate data field formatting.

The only other option (right now) is to use multiple items on the layout, each with the proper formatting in place, and with mutually exclusive printing conditions. This can be applied to any type of report item (not just data fields) but can be a bit cumbersome to setup.

HTH,

Jan Schenkel.
