Create previous button with no changes on variables

Thu, 24 Apr 2014 08:15:41 GMT

hello,

I have buttons that shows me tables or caches through a variable.

Now when I want to go to my previous selection, it takes into account the change of my variables.

How to retrieve only the previous selection without taking into account changes in my variables?

Thank you in advance

Can you provide some sample apps or sample file?

Here is an example. With the previous button if I changed my variable vHide after selecting an operator, the previous button returns the old value of vHide.

thanks for your help.

Like this?

Update : add one more action in Previous Button

Add >> External >> Set Variable >>

Variable

vHide

Value

=IF(vHide = 0,0,1)

'Back' is not actually 'previous selection' it is 'back operation' , for back selection use set expression with $1 like in attached sample.

Thanks but I have a lot dimensions in my application.

The solution from Manish seems good.

I have a problem. My variable does not change but I can not recover the previous selection.

Sorry,I thought it was good.

Have you another idea?

thanks

It's working but only for one Back....

Yes, so there is no solution to just fetch previous selections!

But for a pleasant navigation, I do not see any other solutions as buttons.

Perhaps, with the v12...

For that have to create one more action in button.

right click on button>>Go to button properties>> Action>>Add>> External>> Set Variable.

Variable : Vhide

Value :

If (Vhide=0,0,1)

thanks, it's working but I can't recover the previous selection. It's only for previous action.

So, it's not really a perfect solution.
