You can keep the controls in a seperate table and write an unbound rule to show or hide this table with controls and you can call this rule in the changed event of checkbox and view initialize.

event be like:

Changed event of checkbox,

if checkbox contains value "t"

show controls

else 

hide controls

Good day  @skb_ev;

Addtional to the above mentioned, please see this formal doc which I believe is explains the logic rules proper(http://help.k2.com/onlinehelp/K2Five/UserGuide/5.3/default.htm#Create/K2Designer/Rules/ServerRules.htm),

checkout with this form's properties setup for k2Designer rules(http://help.k2.com/onlinehelp/K2Five/UserGuide/5.3/default.htm#How-Tos/SetFormProperties/HowToUseSetFormPropertiesAction.htm) and http://help.k2.com/onlinehelp/K2Five/UserGuide/5.3/default.htm#Create/K2Designer/Rules/ServerRules.htm#Server_Conditions

However should you feel the issue is still not properly addressed, you can submit a feature request here(https://ideas.k2.com/).

Kind regards;

Hi Viktor

Step1:

Create an Item View :

=>Click on Contact TextBox and Untick Visibility

=>so when a view start, will only going to see firstName TextBox 

Step2: Click On Rules

See Attached Rules

=>(First Configure) then set the properties of Text Box1 control (Configure)

=>Click Configure

Note [If you want to Hide/Show more than one textbox just add the statement:

"then set the properties of Text Box1 control (Configure)" and change Text Box1 name to the correct  textbox ]

=>(Second Configure) then set the properties of Text Box1 control (Configure)

=>Click Confiqure

Results (Output)

Before the CheckBox is Ticked

After the CheckBox Is ticked

If u untick it

Hi Skb_ev

This solution hide certain row and close the space in between, Unlike the one i provided before where it hide the textbox but the space remain.

See the following steps to successfully hide and unhide a Row.

Step1: Create an item view.

         =>The Item view must have 1 row and 1 column and drag a table set it to 1 row and 2 column

         =>drag another table to that item view that contains 1 row and 1 column (Repeat 4 times) e.g

Hint: All 4 table row and column has been inserted in 1 row for item view, see blow screenshot

Step2: Click the table for the view on top and go to rules

          => When the View executed Initialize 

          => then set the properties of Table3 control (Confiqure)

=> Click (Configure) and set Visible to No e.g

Step3: Click checkbox to be highlighted and go to Rules e.g

=>Type the following Rules

    => Click the first (Configure) set visible to yes e.g

>Click second (Configure) set visible to No e.g

 

Results should be like this (see info below) 

=> Contact row has been hidden from start when a view initialize

=>After the checkbox has been checked, the contact row will appear between LastName row and Email Address

=> If you uncheck it, Contact row will disappear (etc etc etc)

LET ME KNOW IF THIS IS WHAT YOU WHERE LOOKING FOR OR YOU WANT ME TO DO SOME CHANGES

Dear Elvis

Dear Widson

Thank you for your tipps. I will have a look at the server side rules and do some tests if this could speed up my views an forms a little bit.

But what I was asking for was a "switch visibility" action to prevent the "if control has value than show that else hide that". It would be much easier if I could say "if control changed then switch visibility for control x, y, z"

Like the ".toggle()" function in jquery.

It's the some

Dear Elvis

Thank you for your proposal but as I allready "said" to the other 2 guys:

I don't need a "howto" I was asking for a "switch visibility" function. I ALLREADY KNOW! that I could do it with "if this than that (else other that)".

I will create an "idea" at idea.k2.com

Thank you all

regards

Viktor
