Question

How can you dynamically name a cfform or cfgrid?

Asked by: leerljr68

I have a cfgrid inside a loop so that a different grid is created for each iteration of the loop. The problem is, to show all the grids, they each have to have a different name. How can I dynamically name each grid so that this works?

I tried setting up the FormName in a CFset, but CFgrid does not like the #FormName# in the name.

<cfset GrdHeight = (qryLOBContact.recordcount * 20) + 20 >
<cfset FormName = "#LOB_ID#ContactList"><cfdump var="#FormName#">
 
<cfform format="flash" action="?Act=upd" name="ContactList" skin="haloBlue" accessible="true" height="#FrmHeight#" width="935">
<cfgrid name="#FormName" format="flash" query="qryLOBContact" height="#GrdHeight#" colheaderbold="true" colheadertextcolor="##067ab4" >

I'm assuming your are only creating _one_ form, but multiple cfgrids.  I haven't tried it, but your code should work, or maybe a slight variation:

<cfloop from="1" to="#howeverManyGrids#" index="counter">
    <cfgrid name="ContactList#counter#" ....>
</cfloop>

OR using a query

<cfloop query="yourQuery" >
    <cfgrid name="ContactList#currentRow#" ....>
</cfloop>

 

by: azadisaryevPosted on 2009-10-22 at 08:22:21ID: 25635267

hope your error is not because you are missing the closing # in <cfgrid name="#FormName"...

'cos as _agx_ said, it should work just fine

The problem is, ANY time I put # in the cfgrid name, it fails. When I just name it, it works for the first grid and fails for the rest.  I've tried dynamically naming the forms and the grids, because I don't care which one truthfully, as long as the out put works.

 

by: leerljr68Posted on 2009-10-22 at 08:32:20ID: 25635397

When I use the code in the post this is what happens:  The queries and data from the loop show up, but not the grids.

 

by: _agx_Posted on 2009-10-22 at 08:33:02ID: 25635403

It has to be somethin else in your code, because this works just fine:

<cfset howeverManyGrids = 5>
<cfform format="flash" action="?Act=upd" name="ContactList" accessible="true" width="935">
	<cfloop from="1" to="#howeverManyGrids#" index="counter">
		<cfoutput></cfoutput>
    	<cfgrid name="ContactList#counter#" format="flash">
			<cfgridcolumn name="firstName" header="First Name">		
			<cfgridcolumn name="lastName" header="LastName">
		</cfgrid>
	</cfloop>
</cfform>

Minus that line of course (not needed)

 

by: azadisaryevPosted on 2009-10-22 at 08:37:29ID: 25635453

yes, i can also assure you that a cf variable as name of cfgrid works just fine.

does your #LOB_ID# evaluate to a number?
irc, cf does not like variable names that start with a number.

change your code to this:
<cfset FormName = "ContactList" & LOB_ID><cfdump var="#FormName#">

Okay I tried that and your example does work...let me look at my other code and figure out what I have that is conflicting.  I will post back with questions or award points from there.  Thank you!  Great start here.

 

by: azadisaryevPosted on 2009-10-22 at 08:38:32ID: 25635472

yep, confirmed: make sure your dynamic names DO NOT start with a number. only letter or _ (underscore).

> DO NOT start with a number. only letter or _ (underscore).

Yes, non standard field names can create those subtle problems that are hard to spot.  Even though you can do it in some places .. my advice is don't ;-)

 

by: leerljr68Posted on 2009-10-22 at 09:10:27ID: 25635836

Okay...after fussing with this I got it.  Thanks to you both!  I will get the points award and close the question.
