Title: Change color on a field on a form
Post by: McTim on March 01, 2012, 04:46:38 PM

I have a netwebform with an entry field and a readonly field.  Upon completion of the entry field, I call a procedure which does many things and returns a value.  I display this value in a readonly field o nthe same form.   I would like to change the color of the readonly field based on data within the result from my other procedure.   How do I go about this?   

BTW, using Nettalk 4  Clarion 8

you would create a condition to set the css of the read-only field.
View the generated source of the procedure, you want to be embedding in the Value::fieldname routine (where fieldname is the use equate of the read-only field.)

you'll see the class is set there (I don't remember NT4, but in NT6 it's "loc:class".

you would want to create a bunch of classes, in your own css file, setting the background-color property.

Then you can set loc:class here to the css class you want.

Unfortunately I don't remember all the specifics of NT4 so I can't be a lot more specific.

Bruce -
  Here is that routine cut from the generated source.  I'm not sure if I have an embed point available.  I have figured out that for now, I should be able to set it to Required (which will turn it RED) when it meets my condition but, not sure where/how to do this.

  My condition is basically 
      if result[1:2] = 'N,'
         !set color to RED
      else
         ! set color to green
      end

Thanks

Enter a local variable in the required condition i.e. loc:conditionvar
In the source  --- >

Value::Result  Routine
  ! Start of "Set Value"
  ! [Priority 5000]

------------------Place your condition here and set loc:conditionvar to true or false for required or not.   

  ! End of "Set Value"
  p_web._DivHeader('GetTicketNumber2_' & p_web._nocolon('Result') & '_value','adiv')
  ! Start of "Set Value"
  ! [Priority 5000]
 
  ! End of "Set Value"
  loc:extra = ''
  ! --- STRING --- Result
    loc:AutoComplete = 'autocomplete="off"'
  loc:readonly =Choose(loc:conditionvar,'readonly','')
  loc:fieldclass = 'FormEntry'
  If loc:conditionvar
    loc:fieldclass = clip(loc:fieldclass) & ' ' & 'formreadonly'
  End
  loc:fieldclass = clip(loc:fieldclass) & ' ' & 'formreadonly'
  If lower(loc:invalid) = lower('Result')
    loc:fieldclass = clip(loc:fieldclass) & ' ' & 'formerror'
  End
