Re: How to show / hide individual column of a DefaultDataTable using Ajax?

[ramlael]

I need som help with how to create an expandable row in a datatable. The 
idea would be to have functionality like an accordion where you click the 
table row and it expands to show more details of the object in the current 
row. 


U have mentioned "This is working fine for the table content (data rows) ",
Please can you provide the code?.

How to show / hide individual column of a DefaultDataTable using Ajax?

[Erich W Schreiner]

Dear all,

I'm trying to implement an Ajax button for showing / hiding some columns of a 
DefaultDataTable based on a Boolean associated with a custom session. Currently 
I have implemented an AttributeModifier that sets the style to "display:none" 
on 
the hidden columns.

This is working fine for the table content (data rows) where I am adding this 
AttributeModifier to the cellItem, but not for the column headers. The function 
getHeader() returns a Label that I can hide by adding the same 
AttributeModifier, but I do not know how to get to the  element itself. 
Effectively, I can hide the headers' label but not the header.

Any suggestions, please?

TIA & best regards,
Erich
