Hide Unhide Subform Columns

Try the following revised code

'hide all columns first
  For intCounter = 0 To NumFields
    Me.subformCertData.Form.Controls(lstFieldList.ItemData(intCounter)).ColumnHidden = True
  Next intCounter
 
'unhide the necessary columns
    For Each vItem In Me.lstFieldList.ItemsSelected
    Me.subformCertData.Form.Controls(lstFieldList.ItemData(intCounter)).ColumnHidden = Not (lstFieldList.Selected(intCounter))
  Next vItem

Select allOpen in new window

Can you please explain your requirement a bit more, it is unclear to me.

thanks

Well, it looked to me that in your code you're looping through each field to hide it, but then you run another loop to hide/display all selected items in the listbox. By using the revised code, you would first hide all coulmns and then loop to display all of selected items in the listbox.  There are other ways to accomplish this, but I thought I'd use the code you had and just reoreder it a bit.  Give it a try to see if it works...if it doesn't you can always change it back :)

" subform columns"

Is this subform in Datasheet View or Continuous View ?

mx

The subform is in Continous View

The ColumnHidden  property only applies to Datasheet View.  You need to use the Visible property.

mx

I tried it, and it didn't work.  

irudyk is there any solutions you could think of to hide unhide columns that might work better?  At this point I'm open to suggestions.  

the best way to do it is to Re-Arrange the fields:

Although you can set the field property to hidden (OR set its width to Zero), but that will leave an empty space in place of the hidden field (which is a column here),

so you will have to move the other columns to fill this space, thus Re-Arrange the fileds (columns).

And if you really want to hide columns, I would consider Datasheet View.

mx

I've changed ti to Datasheet view, and its still not doing it.  

I agree with mx,
that would be your easiest way out, which would take you a minute to do,
and irudyk already gave you the code to hide/unhide.

jaffer

way to go mx :)

Its still not hiding and unhiding the proper columns could something be preventing it from hiding and unhiding the right columns?  I'm selecting the items I want from a list box, the sub form is in data sheet view, and then I click on the list box to hide and unhide the columns I want.  The only problem is that it is hiding and unhiding the wrong columns.  

can you please upload a sample mdb, so that we can give the right solution.

jaffer

The program consists of a front end and backend database.  The password to get to the Administrative view of the front end database is Trial1.  It must be typed in exactly as Trial1.  It can be found in the tblPassword table where the user name is SysAdmin in the backend database 06-07 IT CertificationNew_be.mdb database located in the ITCertBE folder.  Wow that was a mouthful lol.  
The back end must be in the ITCertBE folder in order for it to work.  

You won't be able to see the code unless you enter Trial1 as the password.  Once the password has been entered, click the EnterAdminView button, find the frmSearch form and find the SortSubform function.  That is the function I'm having trouble with.

Hope that helps jafferr:

Thanks very much capricorn1.  

My real problem occurred cause I had not added the field to the subform and then I somehow got distracted and went on a tangent lol.  Great help and timely.
